In this paper, the authors found the pyritized rod like bacteria in desmocollinite and the Cyanophytes’s gelationous sheath and the degraded organic matter of blue green algae in collinite of high sulfur coal seams No.
应用带能谱仪的扫描电镜(SEM-EDX)和透射电镜(TEM),在乌达矿区高硫煤9煤层和10煤层的基质镜质体中发现了黄铁矿化的杆状菌落,在无结构镜质体中发现了蓝藻胶鞘及其降解有机质,这些菌藻类体的发现表明低等生源在高硫煤形成过程中起了重要作用。
The insecticidal toxin protein isolated from Photohabdus bacteria was with high effect and broad spectrum,therefore,the limited anti-insect transgenic crops gene resources were supplemented.
Bt制剂的大量使用及表达Bt毒素的转基因植物的应用已引发了抗性昆虫种群的发展,光杆状菌属细菌产生的杀虫毒素蛋白是一类高效、杀虫谱广的新型杀虫蛋白,使得有限的用来开发转基因抗虫作物的基因资源得到了补充。
