功能性有机物料腐熟剂的生产与应用 总被引:1,自引:0,他引:1
《化肥工业》2015,(1)
将枯草芽孢杆菌、苏云金芽孢杆菌、深绿木霉菌、酿酒酵母菌、白腐菌分别通过固体发酵和液体发酵制备成菌剂,然后按一定的质量比进行混合,制得的粉状功能性有机物料腐熟剂具有效果好、能防控有害生物、使用方便的特点。通过玉米秸秆腐熟效果试验,证明该功能性有机物料腐熟剂可加速玉米秸秆的腐熟,提高小麦产量。 相似文献

硝基苯有巨毒,易导致癌症,在工业上硝基苯被大量使用,造成环境污染.在硝基苯的生化处理过程中,如果选择不当在发酵过程中易产生苯胺、亚硝酸盐等二次污染物.本文通过应用高酒精耐爱性短小芽孢杆菌(Bacillus pumilus)ZY05处理硝基苯污染,经发酵试验短小芽孢杆菌在降解硝基苯污染的过程中不产生苯胺,亚硝酸盐等有毒代谢产物,优化了短小芽孢杆菌对硝基苯的降解条件. 相似文献

Protocatechuic acid, or 3,4-dihydroxybenzoic acid, is produced by both soil and marine bacteria in the free form and as the iron binding component of the siderophore petrobactin. The soil bacterium, Bacillus thuringiensis kurstaki ATCC 33679, contains the asb operon, but does not produce petrobactin. Iron restriction resulted in diminished B. thuringiensis kurstaki ATCC 33679 growth and the production of catechol(s). The gene product responsible for protocatechuic acid (asbF) and its receptor (fatB) were expressed during stationary phase growth. Gene expression varied with growth temperature, with optimum levels occurring well below the Bacillus anthracis virulence temperature of 37 °C. Regulation of protocatechuic acid suggests a possible role for this compound during soil growth cycles. 相似文献
