Changes in enzymes activities of soil samples exposed to electromagnetic radiations (EMR) from mobile phone

This study aimed at investigating the changes in activities of dehydrogenase, catalase, alkaline phosphatase, acid phosphatase and alkaline protease of soil samples exposed to electromagnetic radiations (EMR) from mobile phone for the periods of 0, 30, 60 and 90 days. EMR-unexposed soil samples served as the source of control enzyme activities. The mean enzyme activities from the EMR-exposed soil were significantly...

Higher tolerance of a novel lipase from Aspergillus flavus to the presence of free fatty acids at lipid/water interface

The main objective of this work was to identify novel lipases of industrial interest. In this paper, Aspergillus flavus lipase (AFL) was isolated from the traditional tannery of Fez city in Morocco; it kept its stability even in the presence of high concentrations of detergent from 0 to 10 mM sodium deoxycholate (NaDC). Bile salts showed no inhibitory effect on the lipolytic activity, whereas the calcium salts showed a...
