The purpose of this research was to study the biocide effect of three agroindustrial subproducts, concretely sugar beet, sugar cane and wine vinasse. Results from in vitro testing determined that wine vinasse is what shows a 100% capacity to suppress fungal growth with concentrations between 5% and 7% for Fusarium oxysporum f.sp. melonis race 0 and 1, Sclerotinia sclerotiorum, Pythium aphanidermatum and Phytophthora parasitica and 10-15% for F. oxysporum f.sp. radicis-cucumerinum. On the other hand, sugar cane vinasse produced an increase at high concentrations and sugar beet vinasse showed an approximate 100% suppressor effect on fungal growth for only some of the phytopathogens tested: S. sclerotiorum (15%), P. aphanidermatum (7%), P. parasitica (15%) and F. oxysporum f.sp. radicis-cucumerinum (15%). In the soil samples analyzed none of the three vinasse extracts decreased fusaric microbiota, producing an increase in the three samples tested. This would implicitly convey an improvement in soil quality by producing a potential increase in bacterial and fungal microbiota. 相似文献

A new methodology of biological treatment and conversion of farm waste (manure and wash water) with the use of intensively cultivated phototrophic microorganisms (microalgae) is reviewed. Criteria for selection of microalgae and peculiarities of their intensive cultivation for efficient removal of biogenic elements from and destruction of the organic components of the wastes as well as the possibilities of cost-effective utilization of the resulting microalgal biomass are considered. Advantages and drawbacks of the new methodology are compared with those of conventional anaerobic techniques. Special attention is paid to the integrated technologies combining the aerobic conversion methods with microalgal post-treatment. 相似文献
