Streptomyces padanus strain PMS-702 is an antagonist of Rhizoctonia solani AG-4, the causal agent of damping-off of cabbage. Treatment of cabbage seeds with the culture filtrate of S. padanus strain PMS-702 was effective in reducing the incidence of damping-off of cabbage. The major active ingredient from the culture filtrate of S. padanus strain PMS-702 was purified by silica gel column chromatography and identified as the polyene macrolide, fungichromin, by NMR and mass spectral data. Bioassay studies showed that fungichromin had a strong antifungal activity against R. solani AG-4, and its minimum inhibitory concentration (over 90% inhibition) was found to be 72 mug/mL. This is the first report of fungichromin from S. padanus as an active ingredient for the control of Rhizoctonia damping-off of cabbage.

Though the Java programming language was designed with extreme care, there are still a few ambiguities and irregularities left in the language. The ambiguities are those issues that are not defined clearly in the Java language specification. The different results produced by different compilers on several example programs justify our observations. The irregularities are issues that often confuse programmers. It is hard for a confused programmer to write robust programs. Furthermore, a few issues of the Java language are left intentionally open to the compiler writers. Their effects on Java programs are discussed. The problems of ambiguity, irregularity, and dependence on implementations frequently trap an incautious Java programmer. Some suggestions and solutions for the problems are provided in this paper. (C) 2003 Elsevier Inc. All rights reserved.
