Abstract Diversity of the functional genes encoding dissimilatory nitrite reductase was investigated for the first time in denitrifying halobenzoate degrading bacteria and in two 4-chlorobenzoate degrading denitrifying consortia. Nitrite reductase genes were PCR-amplified with degenerate primers (specific to the two different types of respiratory nitrite reductase, nirS and nirK), cloned and se...

Environment is recognized as a huge reservoir for bacterial species and a source of human pathogens. Some environmental bacteria have an extraordinary range of activities that include promotion of plant growth or disease, breakdown of pollutants, production of original biomolecules, but also multidrug resistance and human pathogenicity. The versatility of bacterial life-style involves adaptatio...

Pakistan is among top three chickpea producing countries but the crop is usually grown on marginal lands without irrigation and fertilizer application which significantly hampers its yield. Soil fertility and inoculation with beneficial rhizobacteria play a key role in nodulation and yield of legumes. Four kabuli and six desi chickpea genotypes were, therefore, evaluated for inoculation respons...

Baeocera franzi (Löbl, 1973) mutator 2000 recorded for first time Zhejiang province, binhanum (Pic, 1922) Scaphoxium intermedium ...

During parasitological surveys in the Okavango Delta and Panhandle in Botswana, two species of climbing perches belonging to the family Anabantidae were investigated for ectoparasites. The fishes were the blackspot climbing perch, Microctenopoma intermedium (Pellegrin) and the manyspined climbing perch, Ctenopoma multispine Peters. Five trichodinid species were found from the skin, fins and gil...
