Isolation of kerosene-degrading bacteria from soil samples and determination of optimal growth conditions
Summary
Researchers isolated bacteria from kerosene-contaminated soil capable of breaking down rocket fuel hydrocarbons, identifying promising candidates for bioremediation of fuel-contaminated sites.
Bacteria capable of decomposing hydrocarbon rocket power kerosene T-1 were isolated and studied. In the course of the studies, 30 isolates of microbial cultures were isolated from soils contaminated with hydrocarbon rocket fuel, of which 9 isolates were selected that actively assimilate kerosene T-1 as the only headwater of carbon. The strains that showed the best results in these screening analyses on four nutrient media with a concentration of T-1 kerosene 1% (10 g/kg) grow well 9 isolates of culture microorganisms: 4, 8, 14, 23, 5, 18, 20, 25 and yeast 12/5. Isolates on a medium with a concentration of T-1 kerosene 2% (20 g/kg) and 5% (50 g/kg) showed good growth in bacterial cultures 5, 18, 20, 25, and yeast 12/5.

Enhanced remediation of petroleum in soil by petroleum-degrading bacterium strain TDYN1 and the effects of microplastics
Researchers conducted a pot experiment to evaluate the petroleum hydrocarbon degradation capability of bacterium strain TDYN1 in soil and to assess how microplastics affect the bioremediation process. They found that while TDYN1 effectively degraded total petroleum hydrocarbons (TPH), the presence of microplastics in soil influenced degradation dynamics, with implications for in situ bioremediation strategies.
