Anaerobic Degradation of the Invasive Weed L. () and Copper Immobilization by a Community of Sulfate-Reducing and Methane-Producing Bacteria.

The weed L. poses a global threat to the environment as it spreads uncontrollably on roadsides, in forests, fields, meadows, and farmland. Goldenrod emits toxic substances that suppress other plants on the site, displacing wild ones.

[Diversity and Physiological and Biochemical Properties of Heterotrophic Bacteria. Isolated from Lake Baikal Neuston.].

For heterotrophic microorganisms (44 strains) isolated-from the surface film of Lake Baikal, iden- tification was carried out and their. physiological and biochemical characteristics were determined. Com- pared to the water column, diversity of cultured heterotrophs was low, indicating formation of stable micro- bial communities at the air-water interphase interface.

Results from the Survey of Antibiotic Resistance (SOAR) 2011-13 in Ukraine.

Objectives: To determine the antibiotic susceptibility of respiratory isolates of Streptococcus pneumoniae and Haemophilus influenzae collected in 2011-13 from Ukraine.

Methods: MICs were determined by CLSI broth microdilution and susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints.

Results: A total of 134 isolates of S.

[Resistance to Dehydratation of Extremophilic Bacteria from Antarctic Region and Hypersaline Reservoirs].

Purpose: To determine resistance to dehydratation of bacteria resistant to UV irradiation.

Methods: Objects of research - extremophilic bacteria (from Antarctic islands and hypersaline reservoirs of Israel and Crimea). Dehydratation of bacteria was carried out in sealed desiccator; the exposure without access of moisture was 5 weeks, temperature - 22 - 25 °C, humidity - 1 - 4 %.

PHYLOGENETIC ANALYSIS AND AUTECOLOGY OF SPORE-FORMING BACTERIA FROM HYPERSALINE ENVIRONMENTS.

Multi-resistant to extreme factors spore-forming bacteria of Bacillus genus are isolated from hypersaline environments of the Crimea (Ukraine) and the Dead Sea (Israel). Phylogenetic analysis showed distinction of dominating extremophilic culturable species in studied regions. In Crimean environments they are B.
