in pakistan besides pesticide contamination from agricultural field, the manufacturing industriesare also contributing relatively high quantities of toxic pesticides into the environment. these pesticides maybe toxic, mutagenic or carginogenic and may be bioaccumulated or biomagnified by the biota. because ofpersistent nature of pesticides, its removal from environmental system become difficult...

BACKGROUND This study aimed to develop a biocontrol system for ginseng root rot caused by Fusarium cf. incarnatum. METHODS In total, 392 bacteria isolated from ginseng roots and various soils were screened for their antifungal activity against the fungal pathogen, and a bacterial isolate (B2-5) was selected as a promising candidate for the biocontrol because of the strong antagonistic activit...

Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...

We report an easy procedure for isolating chromosome-clustered genes. By following this methodology, the entire set of genes belonging to the phenylacetic acid (PhAc; 18-kb) pathway as well as those required for the synthesis and mobilization of different polyhydroxyalkanoates (PHAs; 6.4 kb) in Pseudomonas putida U were recovered directly from the bacterial chromosome and cloned into a plasmid ...

Antifungal activity of air contaminant bacterial isolate was evaluated against Curvularia specie at different pH and temperature. The bacterial isolate was found to be active at 7.0 pH and 30°C and preferred inulin and starch as carbon source. The inhibitory antifungal compound was eluted in water and methanol that exhibited good activity as compared to other solvents. The methanol extracts of ...
