Herbicides and its transformation products have been reported in ground water and the non toxic organism and environment can be affected. For this purpose the leaching potency of fenoxaprop-p-ethyl and atrazine (tracer) in silty loamy soil was conducted in columns under disturbed soil laboratory condition with average rain fall of 90 mm per week (assuming worst case scenario) to every of soil column. Fenoxaprop-p-ethyl was applied at two different applications rate to the soil cores. Similarly atrazine was also applied at the recommended rate. The leachates were collected on weekly basis from...

Xylanase enzymes are group of enzymes that can degrade Xylan present in plants. Xylan lignin and cellulose formed a complex matrix in plants. Lignin imparts colour to cellulose and thus eventually imparts colour to paper and pulp. Xylanase facilitates the removal of lignin from the paper pulp thus improves the brightness of paper. Xylanase was produced by Aspergillus niger using different carbon sources. UV irradiation of Aspergillus niger slightly improves the Xylanase activity than native Aspergillus niger. Twenty minutes exposure of Aspergillus niger to UV irradiation was considered...
