Some generalizations based on stratification and vertical mixing in meromictic Lake Shira, Russia, in the period 2002-2009 / D. Y. Rogozin [et al.] // Aquatic Ecology. - 2010. - Vol. 44, Is. 3. - P485-496, DOI 10.1007/s10452-010-9328-6 . - ISSN 1386-2588

Аннотация: In a brackish, temperate, 24-m-deep Lake Shira, the profiles of salinity, temperature, oxygen and sulfide concentrations were measured on a seasonal basis from 2002 to 2009. The lake was shown to be meromictic with autumnal overturn restricted to mixolimnion. The depth of mixolimnion and position of oxic-anoxic interface varied annually. The spring mixing processes contribute to the formation of mixolimnion in autumn. The exceptionally windy spring of 2007 caused the deepening of mixolimnion in the winter of 2008. The winter position of oxic-anoxic interface was affected by the position of lower boundary of mixolimnion in all winters. The salinity in the winter mixolimnion increased compared with the autumn because of freezing out of salts from the upper water layers meters during ice formation and their dissolution in water below. The profiles of salinity and temperature were simulated by the mathematical 1-D model of temperature and salinity conditions taking into account ice formation. The simulated profiles generally coincided with the measured ones. The coincidence implies that simplified one-dimensional model can be applied to roughly describe salinity and density profiles and mixing behavior of Lake Shira. В© 2010 The Author(s).

Effect of way of cooking on content of essential polyunsaturated fatty acids in muscle tissue of humpback salmon (Oncorhynchus gorbuscha) / M. I. Gladyshev [et al.] // Food Chemistry. - 2006. - Vol. 96, Is. 3. - P446-451, DOI 10.1016/j.foodchem.2005.02.034 . - ISSN 0308-8146

Аннотация: Contents of fatty acids in filets of unfrozen (control), boiled, fried, roasted and boiled in a small amount of water humpback salmon, collected from a wholesale market in Krasnoyarsk city (Siberia, Russia) were analyzed. Special attention was paid to essential polyunsaturated fatty acids of ?3 family: eicosapentaenoic, 20:5?3 (EPA) and docosahexaenoic, 22:6?3 (DHA). Heat treatment in general did not decrease content of EPA and DHA in humpback, except a modest reduction during frying. Cooked humpback appeared to be the valuable source of essential ?3 PUFAs, namely EPA and DHA. It was hypothesized that the absence of significant reduction of PUFAs' contents in red flesh of fishes of Salmonidae family during heat treatment may be due to a high level of natural antioxidants which formed in the course of evolution as adaptation to their ecological niche.

Direct utilization of human liquid wastes by plants in a closed ecosystem / G. M. Lisovsky [et al.] // Advances in Space Research. - 1997. - Vol. 20, Is. 10. - P1801-1804 . - ISSN 0273-1177

Аннотация: Model experiments in phytotrons have shown that urea is able to cover 70% of the demand in nitrogen of the conveyer cultivated wheat. At the same time wheat plants can directly utilize human liquid wastes. In this article by human liquid wastes the authors mean human urine only. In a long-term experiment on "man-higher plants" system with two crewmen, plants covered 63 m2, with wheat planted to - 39.6 m2. For 103 days, complete human urine (total amount - 210.7 1) wassupplied into the nutrient solution for wheat. In a month and a half NaCl supply into the nutrient solution stabilized at 0.9-1.65 g/l. This salination had no marked effect on wheat production. The experiment revealed the realistic feasibility to directly involve liquid wastes into the biological turnover of the life support system. The closure of the system, in terms of water, increased by 15.7% and the supply of nutrients for wheat plants into the system was decreased. Closedness of biological turnover of matter in a man-made "man - higher plants" ecological system might involve, among other processes, direct utilization of human liquid wastes by plants. The amount of urine comprises 15-20% of the total amount of water cycling within the system including water as part of food, household, hygiene and potable water necessary for man. What is more, it they contains most nitrogen-bearing compounds emitted by man, almost all of the NaCl and some other substances involved in the biological turnover. Human liquid wastes can be utilized either by preliminary physical-chemical treatment (evaporating or freezing out the water, finally oxidizing the organic matter, isolating the mineral components required for plants, etc.) and further involvement of the obtained products or by direct application into the nutrient solution for plants. The challenge of direct utilization is that plants have no need of Na+ and Cl-, and also the organic forms of nitrogen emitted by man cannot fully meet the demand of plants forthis element. Besides, hygienic and/or psychological reasons make it desirable to avoid direct use of liquid wastes in the nutrient solutions that would have direct contact with edible part of plants (tubers, roots, bulbs). Feasibility of direct utilization of liquid wastes by plants in a closed "man - higher plants" ecosystem has been experimentally studied on wheat - grain culture as a model plant with the edible part in the form of seeds spatially dissociated with the nutrient medium. The wheat covered 60-65% of the area under higher plants. The studies have been carried out in "Bios-3"experimental facility described in detail elsewhere (Lisovsky, 1979; Gitelson et al., 1989).

Intracellular degradation of poly-?-hydroxybutyrate in the hydrogen-oxidizing bacterium alcaligenes eutrophus / T. G. Volova [и др.] // Mikrobiologiya. - 1999. - Vol. 68, Is. 1. - С. 63-69 . - ISSN 0026-3656

Cell dimensions -- Degradation -- Hydrogen-oxidizing bacteria -- Poly-?-hydroxybutyrate
Аннотация: The intracellular degradation of poly-?-hydroxybutyrate (PHB) in Alcaligenes eutrophus culture was found to occur at different rates, depending on growth conditions. The degradation of PHB probably allows protein synthesis and cell growth under nonoptimal environmental conditions. The isolated native granules of poly-?-hydroxybutyrate were stable, unless they were isolated from biomass subjected to freezing-thawing treatment. Degradation of isolated granules could also be stimulated by increasing the ionic strength of the medium or adding cell-free extracts. It is anticipated that bacterial cells contain soluble factors that either stimulate or inhibit the degradation of PHB granules.

Аннотация: Cold extracts with high activities of enzymes of luminescent reaction were prepared from mycelia of luminous fungi Armillaria borealis IBSO 2328, Mycena citricolor IBSO 2331, and Neonothopanus nambi IBSO 2391. The authors describe techniques of preparing cold extracts with high levels of luminescence from mycelial biomass of different species of luminous basidiomycetes. The investigation of cold extracts showed that in experiments with freezing and thawing of the samples as well as in experiments with lyophilization followed by dissolution of the dry samples, the levels of enzyme activity were high, with in vitro luminescence exhibited after addition of NADPH and the hot extract containing the substrate. High activity levels of the enzymes of luminescent reaction were measured in lyophilized cold extracts stored over three years. In lyophilized preparations, the enzymes of luminescent reaction had high thermostability, even when dry preparations of cold extracts were exposed to a temperature of 100°C for 60 minutes. © Beijing Academy of Agriculture and Forestry Sciences.
