Summary: This study reports the isolation of new bacillus strains with high performances in metabolizing phenols, one of which showed outstanding efficiency in metabolizing phenol at concentrations up to 1200 mg L-1 and degrading a wide range of other phenolic compounds simultaneously. The genes encoding phenol hydroxylase (PH) and catechol-2,3-dioxygenase (C23O) were detected and characterized, confirming the degradation of phenol occurs via the meta pathway. This novel strain is believed to be a promising organism for developing more robust and efficient bioremediation processes of degrading phenolic compounds.

Summary: Arsenic is a semimetal toxic to humans, commonly exposed through consumption of contaminated water. This study isolated a high As-resistant bacterium Pseudomonas migulae VC-19 from sediments of the As-rich Camarones River in Chile, showing high rates of As(III) conversion when immobilized on activated carbon. It has the potential for biotechnological application in treating arsenic contaminated waters.

Summary: A new strain, Shinella sp. FLN 14, capable of utilizing fluorene as a sole carbon source and effectively co-metabolizing various PAHs and heterocyclic derivatives was isolated and characterized. The strain exhibited high PAHs degradation activity and showed potential for bioremediation of PAHs-contaminated environments.

Summary: Arsenic mobilization in groundwater systems is influenced by diverse microorganisms and physicochemical factors, with diverse microbial communities found in the Po Plain. The oxidation state of arsenic is a key driver in shaping these communities, with the oxidation rate linearly correlated to As(III) concentration. These findings provide valuable insights for biotechnology-based arsenic bioremediation efforts.

Summary: Oil-contaminated environments are enriched with microorganisms that can utilize petroleum for growth and metabolic activities. Three isolates were identified as Pseudomonas sp., Acinetobacter sp., and Enterobacter sp. respectively. The isolates showed degradation efficacy in diesel oil and burned engine oil, indicating their potential use for bioremediation purposes.

Summary: Bacteriophages, specifically the PHB09 lytic bacteriophage, show promise as a potential biocontrol agent against Pseudomonas syringae pv. actinidiae (Psa) infections, which have become increasingly resistant to conventional treatments. This bacteriophage demonstrates a narrow host range and remains stable under a wide range of environmental conditions, indicating its potential effectiveness in controlling kiwifruit bacterial canker.

Summary: Microorganisms play an important role in degrading edible oil contaminated effluents, especially in the bioremediation of restaurant wastewater. Lipase shows high efficiency and environmental friendliness in waste oil degradation. The supplementation of lipase can enhance the performance of lipolytic consortium, leading to a decrease in oil and chemical oxygen demand values in restaurant wastewater.

Summary: This study successfully overexpressed the AzK gene in Escherichia coli for the efficient degradation of Remazol Red-R and Acid-Blue 29 dyes. Optimal conditions were determined as 1.5% inoculum size, 0.5 mM IPTG concentration, and 6 hours incubation time. The crude extract achieved 76% and 74% decolorization of RRR and AB-29, while the purified enzyme achieved 94% and 93% decolorization within 0.3 hours. Kinetic analysis revealed the enzymatic characteristics and HPLC and GC-MS analyses confirmed the effective biotransformation of dyes into less toxic metabolites. This study highlights the potential of recombinant azoreductase for the degradation of textile azo dyes.

Summary: To counter the increased deposition of greenhouse gases in the atmosphere, alternative fuels to replace conventional fossil fuels have become necessary. This study investigated two different samples as anolytes for microbial fuel cells, which can generate energy by utilizing organic substrates. Strains A1 and A2 produced the highest voltage outputs, while strain A6 generated the least electricity.
