Аннотация: The effect of 0.3 and 0.7 M NaCl on biomass yield, total nitrogen content, intracellular lipid content, and fatty acid profile of the lipids of the alga Botryococcus braunii IPPAS H-252 in different phases of the culture cycle was studied. The presence of sodium chloride in the medium inhibited the growth of algal cells for the first 3 days of the experiment, causing a decrease in total nitrogen, enhanced synthesis of triacylglycerols, and considerable changes in the lipid fatty acid profile: decreases in polyenoic acid contents (from 68.34% to 29.38% and 12.8%) and proportions of long-chain saturated acids (from 0.53% to 5.3% and 14.13% of the total fatty acids) at 0.3 M NaCl and 0.7 M NaCl, respectively. In later phases of the culture, at 0.3 M NaCl, the content of polyenoic acids rose to the values characteristic of the active growth phase of this alga. At 0.7 M NaCl, the proportion of polyenoic acids grew less significantly, but biomass concentration and total nitrogen increased, similarly to the experiment with 0.3 M NaCl.

Аннотация: The effect of nitrogen limitation in a medium on the composition of intracellular lipids in the alga Botryococcus braunii Kutz IPPAS H-252 in the course of culture development was investigated. Under the conditions of nitrogen limitation, the alga under investigation accumulated lipids as triacylglycerols, and this process was accompanied by substantial changes in the total fatty acid (FA) composition, which were manifested in a decrease in trienoic acids (from 52.8-57.2 to 19.5-24.7% of total FAs) and an increase in the content of oleic (from 1.1-1.2 to 17.1-24.4%) and saturated (from 23.7-26.0 to 32.9-46.1%) acids. In the control culture, the directionality of FA redistribution was less marked, and these changes were noticed at the later stages of culture development. Under nitrogen limitation, marked changes in the FA composition of polar lipids occurred by the 13th day, and they were characterized by an increase in the content of saturated acids (up to 76.8%) and a dramatic decrease in the content of all polyenoic acids (up to 6.8%). The changes in the FA composition of triacylglycerols were noticed as early as by the 7th day; these changes consisted in an increase in the content of oleic acid, and its high content (28.4-38.4%) was maintained up to the end of culturing. In the control culture, triacylglycerols with a high content of oleic acid were found by the 13th day, although, by this time, the content of total lipids and triacylglycerols did not change.

Аннотация: A study has been carried out to investigate the influence of nitrogen deficiency on intracellular lipid composition, including total fatty acid composition of lipids, polar lipids, and triacylglycerols, of the alga Botryococcus braunii Kutz IPPAS H-252 in batch culture. Under nitrogen limitation, the alga accumulates lipids as triacylglycerols and the total fatty acid (FA) composition changes: trienoic acids decrease (from 52.8-57.2 to 19.5-24.7% of the total FAs) and the oleic acid increases (from 1.1-1.2 to 17.1-24.4%) as does the saturated acids (from 23.7-26 to 32.9-46.1%). A similar rearrangement in the FA spectrum occurs at later times in the control culture, but it is less pronounced. Under nitrogen limitation, considerable changes in the polar lipid FAs are registered at day 13: saturated acids increase (from 28.6-35.5 to 76.8%) and all polyenoic acids markedly decrease (from 56.9-64.1 to 6.8%). Changes in the triacylglycerol fatty acid spectrum are seen on day 7: the oleic acid increases (from 14.7 to 34.2%) and remains at a high level till the end of the culture. In the control, triacylglycerols with large contents of oleic acid are detected at day 13, the total lipids and triacylglycerols still remaining unchanged. В© Springer 2005.

Аннотация: The structure of liquid hydrocarbons and fatty acids produced by the green alga Botryococcus was identified. Two representatives of this alga, Botryococcus braunii Kutz, strain IPPAS H-252, introduced into culture earlier and an organism isolated for the first time from the Shira Lake, were used for this identification. Fatty acid composition of B. braunii, strain H-252, lipids was characterized by a high content of trienoic acids of C16-C18 series. The hydrocarbon composition of this strain was represented by straight-chain and branched-chain C14-C28 components; long-chain linear aliphatic C20-C27 hydrocarbons (54.4%) and 2,6,10,14-tetramethylhexadecane (20.5%) predominated among them. The strain H-252 differed in its fatty acid and hydrocarbon composition from the strains described earlier as Botryococcus braunii. The fatty acid composition of the Botryococcus isolate was represented mainly by C12-C32 saturated and monoenoic acids. The hydrocarbons formed by this isolate were represented by dienoic and trienoic components. C29 (48.9-56.3%) and C31 (11.1-16.3%) hydrocarbons predominated among the C23-C31 dienoic hydrocarbons, and C27, C29, and C31 trienoic hydrocarbons comprised 2.5-2.6% of total hydrocarbons. This type of hydrocarbons and the lipid fatty acid composition were characteristic for the race A of B. braunii.

A Temperature Dependence of the Intra- and Extracellular Fatty-Acid Composition of Green Algae and Cyanobacterium / N. N. Sushchik [et al.] // Russian Journal of Plant Physiology. - 2003. - Vol. 50, Is. 3. - P374-380, DOI 10.1023/A:1023830405898 . - ISSN 1021-4437

Аннотация: The effect of ambient temperature on the composition of intracellular fatty acids and the release of free fatty acids (FFA) into a medium by cyanobacterium Spirulina platensis and eukaryotic microalgae, Chlorella vulgaris and Botryococcus braunii, was studied using their batch cultures. It was found that all the species studied, regardless of their taxonomic status, responded to the temperature regime by similar changes in their intracellular fatty acid composition: the relative content of more unsaturated fatty acids decreased with the elevation of temperature. At the same time, in the prokaryote, this temperature shift blocked, first of all, the elongation of 16: 0 to 18:0 and then their further desaturation. In eukaryotes, the change in the desaturation of dienoic to trienoic fatty acids was the most pronounced process. The ratio of dienoic to trienoic fatty acids remained almost unchanged in S. platensis. The relative content of extracellular unsaturated FFA increased in the prokaryotic organism S. platensis at a higher temperature. But no significant changes in the composition of extracellular unsaturated FFA were detected in eukaryotic algae upon temperature elevation.

Аннотация: Lipid composition and hydrocarbon structure of two colonial green algae of the genus Botryococcus, i.e., a mu seum strain and a field sample collected for the first time from Lake Shira (Khakasia, Siberia), have been compared. Polar lipids, diacylglycerols, alcohols, triacylglycerols, sterols, sterol esters, free fatty acids and hydrocarbons have been identified among lipids in the laboratory culture. The dominant fraction in the museum strain was formed by polar lipids (up to 50% of the lipids) made up of fatty acids from C12 to C24. Palmitic, oleic, C16 - C18 dienoic and trienoic acids were the main fatty acids of the museum strain. Aliphatic hydrocarbons were found in the lipid of the museum strain. However, these amounted maximally to about 1% of the dry biomass at the end of exponential growth phase. The qualitative and quantitative compositions of FAs and hydrocarbons of the museum strain of Botryococcus, (registered at the Cambridge collection as Botryococcus braunii Kutz No LB 807/1 Droop 1950 H-252) differed from those of the Botryococcus strain described in the literature as Botryococcus braunii. The Botryococcus sp. found in Lake Shira is characterized by a higher lipid content (< 40% of the dry weight). Polar lipids, sterols, triacylglycerols, free fatty acids and hydrocarbons have been identified among lipids in the field sample. The main lipids in this sample were dienes and trienes (hydrocarbons < 60% of total lipid). Monounsaturated and very long chain monounsaturated fatty acids, including C28:1 and C32:1 acids, were identified in the Botryococcus found in Lake Shira. The chemo-taxonomic criteria allow us to unequivocally characterize the organism collected from Lake Shira as Botryococcus braunii race A.

Аннотация: The lipid composition of the green alga Botryococcus was studied at three different cultivation temperatures: suboptimal (18В°C), optimal (25В°C), and supraoptimal (32В°C). Cultivation at the supraoptimal temperature was found to considerably inhibit the synthesis of nearly all intracellular lipids, except for triacylglycerides, and to influence their fatty acid composition. In particular, the content of trienoic fatty acids was significantly lower at the supraoptimal than at the optimal cultivation temperature. At the same time, the fatty acid composition of the extracellular lipids of the alga virtually did not depend on cultivation temperature. В© 2002 MAIK "Nauka/ Interperiodica".

Аннотация: The lipid fraction of the green alga Botryococcus cultured in a batch mode was found to contain polar lipids (more than 50% of the total lipids), di- and triacylglycerols, sterols and their esters, free fatty acids, and hydrocarbons. In aging culture, the content of polar lipids somewhat decreased and that of triacylglycerols increased by more than four times. The content of hydrocarbons in the algal biomass did not exceed 0.9% and depended little on the culture age. Intracellular lipids contained saturated and unsaturated (mono-, di-, and trienoic) fatty acids. The maximum content of C16:3 and ?-C18:3 fatty acids (up to 35% of the total fatty acids) was detected in the phase of active growth. The extracellular and intracellular lipids of the alga differed in the proportion of particular lipids and in the fatty acid pattern. В© 2001 MAIK "Nauka/Interperiodica".

Gut content analysis of Gammarus lacustris from a Siberian lake using biochemical and biophysical methods / M. I. Gladyshev [et al.] // Hydrobiologia. - 2000. - Vol. 431, Is. 2-3. - P155-163 . - ISSN 0018-8158

Аннотация: We studied the gut contents of Gammarus lacustris from the littoral of Shira lake, a Siberian salt lake, by microscopic analysis in conjunction with measuring of fluorescence of chlorophyll and composition of fatty acids. Gammarus ingested primarily fresh seston, probably settled on the bottom. Additionally, the amphipods obtained essential polyunsaturated fatty acids of ?3 family by selectively consuming bottom sediment particles. A considerable part of the ingested seston comprised cells of Botryococcus sp., which passed the intestinal tract in living form and their photosynthetic activity increased. This viable gut passage was likely one of the causes of bloom of Botryococcus in the littoral. Unlike a number of literature data, there was no selective digestion of any fatty acid species, including polyunsaturated acids, in the intestinal tract.

Установлено, что температурная реакция внутриклеточного состава ЖК была схожей у всех изученных видов: независимо от их таксономического положения при повышении т-ры относительное содержание более ненасыщенных ЖК уменьшалось. При этом, у прокариотического вида повышение т-ры вызывало подавление элонгации 16:0 в 18:0 и их дальнейшей десатурации, а у эукариотических видов - снижение десатурации диеновых кислот до триеновых. В противоположность эукариотическим видам, у S. platensis с повышением т-ры соотношение диеновых и триеновых к-т практически не менялось. Для эукариотических водорослей достоверного влияния температурного фактора на состав внеклеточных СЖК обнаружено не было. В то же время у цианобактерий S. platensis относительное содержание ненасыщенных внеклеточных СЖК при повышении т-ры увеличивалось. Ил. 2. Табл. 3. Библ. 31

Batch culture -- Botryococcus braunii -- Liquid hydrocarbons -- Productivity
Аннотация: The growth, productivity, and changes in the chemical composition of the green alga Botryococcus braunii Kutz H-252 were studied at different phases of growth in a luminostat culture. Modification of the Prat medium resulted in an increase in the alga yield to 3.9 g/l and a decrease in the generation time to 3-4 days. The specific growth rate during the exponential phase was 0.235/ day. These values are comparable with the best results obtained abroad. Among the pigments of B. braunii, besides chlorophylls a and b, carotene, lutein, neoxanthin, and violaxanthin were also identified. The highest content of these pigments, based on dry weight, was achieved during the exponential growth phase. During culture aging, there was an accumulation of carbohydrates and lipids in addition to a simultaneous decrease in the concentration of nitrogen-containing substances. It was discovered that this strain can synthesize liquid hydrocarbons. These hydrocarbons were found both in the alga biomass (ca. 1% of dry weight) and among the extracellular metabolites (up to 10.3 mg/l).

Аннотация: Целью работы было получение устойчивой лабораторной культуры и исследование физиолого-биохимических свойств водоросли B. braunii. Штамм B. braunii Kutz H-252 выращивали на модифицированной среде Прата. В результате последовательных пересевов в течение 3 мес была получена более активная культура. Приведены статистически обработанные средние из трех экспериментов результаты роста B. braunii в условиях периодической культуры. Проанализированы состав пигментов и их динамика по ходу роста и старения культуры. Минеральный состав биомассы водоросли в целом типичен для водорослевой культуры. Отмечается высокое содержание калия в биомассе. Прослежен биохимический состав B. braunii в ходе роста. Особое внимание уделено составу липидов. Ил. 4. Библ. 13

Аннотация: Исследованы рост, продуктивность и динамика хим. состава биомассы зеленой водоросли Botryococcus braunii Kutz H-252 в ходе стадийного развития в условиях лабораторной люминостатной культуры. На модифицированной среде Прата получен урожай водоросли 3,9 г/л при сокращении времени генерации до 3-4 сут; уд. скорость роста культуры на экспоненциальной фазе роста составила 0,235 сут{-1}, что сопоставимо с лучшими зарубежными результатами. Среди пигментов у B. braunii идентифицированы, помимо хлорофилла a и b, каротин, лютеин, неоксантин и виолаксантин. Показано, что максимальное содержание данных пигментов на единицу сухой биомассы приходится на экспоненциальную фазу роста. В ходе старения культуры отмечено накопление в биомассе углеводов и липидов на фоне снижения конц-ии азотсодержащих компонентов. Выявлена способность данного штамма к синтезу жидких углеводородов, к-рые обнаружены как в биомассе водоросли ('ПОДОБН'1% к весу сухого в-ва), так и среди экстрацеллюлярных продуктов обмена; максимум внеклеточных углеводородов составил 10,3 мг/л.
