Аннотация: The physiological, biochemical, genetic, and cultural characteristics of the glucose-utilizing mutant strain Ralstonia eutropha B8562 were investigated in comparison with the parent strain R. eutropha B5786. The morphological, cultural, and biochemical characteristics of strain R. eutropha B8562 were similar to those of strain R. eutropha B5786. Genetic analysis revealed differences between the 16S rRNA gene sequences of these strains. The growth characteristics of the mutant using glucose as the sole carbon and energy source were comparable with those of the parent strain grown on fructose. Strain B8562 was characterized by high yields of polyhydroxyalkanoate (PHA) from different carbon sources (CO 2, fructose, and glucose). In batch culture with glucose under nitrogen limitation, PHA accumulation reached 90% of dry weight. In PHA, ?-hydroxybutyrate was predominant (over 99 mol %); ?-hydroxyvalerate (0.25-0.72 mol %) and ?-hydroxyhexanoate (0.008-1.5 mol %) were present as minor components. The strain has prospects as a PHA producer on glucose-containing media.

Заглавие : Phylogenetic diversity of winter bacterioplankton of eutrophic Siberian reservoirs as revealed by 16S rRNA gene sequences

Аннотация: Using 16S rRNA gene sequence analyses we investigated the bacterial diversity of winter bacterioplankton of two eutrophic Siberian reservoirs. These reservoirs show similarity in phytoplankton community composition in spring and autumn but tend to differ in summer in exhibiting cyanobacterial bloom. Forty-eight unique partial 16S RNA gene sequences retrieved from two libraries were mostly affiliated with the class Actinobacteria, ? subdivision of the class Proteobacteria, and the phylum Cytophaga-Flavobacterium-Bacteroides. The clone library of the pond exhibiting summer cyanobacterial bloom showed more diversity in sequence composition. A significant number of bacterial 16S rRNA gene clones were closely related to freshwater bacteria previously found in different aquatic ecosystems. This finding confirms the assumption that some bacterial clades are globally distributed.
