Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

Abstract:: Experiments were conducted to determine both the influence of wood moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products. The fungitoxicity of MIT was studied by determining the product of...
