Abstract:
The toxic effects of 11 kinds of organic solvents on microbial cell were investigated. It was found that methanol, acetonitrile and methylbenzene had evident toxic effects on the surface morphologies of A. niger spores, forcing the spores deformation and even rupture. After incubated with t-Amyl alcohol, the morphology of the A. niger spores showed significant changes in both surface and size. Organic solvents also affected the mycelium morphology, the growth of A. niger and their catalytic abilities. Methanol, acetonitrile and chloroform had the higher toxicities than other solvents, while acetone, isopropanol and isooctane had lower cell toxicities. No evident relationship between solvent toxicity and the logP values of the solvents was found in this research.
