Abstract

A bioassay was used for Pythium sylvaticum-induced damping off of cress seedlings to identify conducive and suppressive peats. It was found at the end of the assay that microbial activity in unconditioned peats was negatively correlated with the counts of P. sylvaticum and there were also significant differences between bacterial sequence populations from suppressive and conducive peats.

Abstract

This article describes a slow sand filter method for the analysis of the spatial and temporal structure of the microbial community in water. Research shows that passage of water through the sand column completely removes the zoospores of Phytophthora cryptogea. The method employs polymerase chain reaction-coupled denaturing gradient gel electrophoresis technique among others.
