We investigated predator-prey interactions in a model system consisting of the bacterivorous flagellate Poterioochromonas sp. strain DS and the freshwater bacterium Sphingobium sp. strain Z007. This bacterial strain tends to form a subpopulation of grazing-resistant microscopic flocs, presumably by aggregation. Enhanced formation of such flocs could be demonstrated in static batch culture exper...

The efficacy of two rhizobacteria (Sphingobium fuliginis TIK1 and Sphingobium sp. IT4) of Phragmites australis for the sustainable treatment of water polluted with phenolic endocrine-disrupting chemicals (EDCs) was investigated. Strains TIK1 and IT4 have recently been isolated from Phragmites rhizosphere and shown to degrade various 4-alkylphenols-TIK1 via phenolic ring hydroxylation and meta-c...

Non-enantioselective alcohol dehydrogenases (ADHs) are rarely found in the biocatalysis portfolio. Generally, highly enantioselective ADHs sought for. Using such for oxidation of racemic alcohols generally results a kinetic resolution starting material, which is unfavourable if ketone represents product interest. In current contribution we report ADH from Sphingobium yanoikuyae ( Sy ADH) as non...

The study highlights a deeper insight of the genes involved in the degradation of diverse number of refractory environmental pollutants, the pool of available genomic data needs to be enhanced. There seems to be a high urgency for such ecologically important microbes to be sequenced and their genomes to be critically analyzed. Sphingobium indicum B90A is the most efficient degrader of Hexachlor...

We have identified and analyzed two DNA regions responsible for stable maintenance of a plasmid in the genus Sphingomonas and Escherichia coli. A 37 bp fragment, upstream of the repA gene, is required for stable maintenance of the low-copy-number small plasmid pYAN-2 (4,687 bp) from Sphingobium yanoikuyae. It does not encode any significant protein sequence and has one direct repeat for possibl...
