Screening for antioxidants of microbial origin.

Abstract

Recently, the development of natural antioxidative substances has been expected to replace the synthetic compounds which are widely used at the present time. Some natural antioxidants of microbial origin have already been isolated, but the screening procedures used were indirect and complicated.1>2) Wehave also tried to isolate these active substances from fungi. In this paper, a simple and direct method for screening, identification and evaluation of the isolates will be described. Filamentous fungi, just isolated from soil samples, were cultured on a reciprocating shaker at 30C for 3 ~4 days.
