Bacterial strain VKM B-2445 is characterized by ethylenediaminetetraacetate (EDTA) requirement for cell growth. This strain could not grow on glucose and organic acids as the sole sources of carbon and energy, but it was able to metabolize these substrates added to EDTA medium. EDTA initiated assimilation of glucose, succinate, fumarate, malate, and citrate and supplied nitrogen for the biomass production from these substrates. Utilization of primarily nongrowth substrates by strain VKM B-2445 started when EDTA was exhausted or at least considerably degraded.
细菌菌株VKM B - 2445的特点是细胞生长需要乙二胺四乙酸(EDTA)。该菌株不能以葡萄糖和有机酸作为唯一的碳源和能源进行生长,但能够代谢添加到EDTA培养基中的这些底物。EDTA启动了葡萄糖、琥珀酸、富马酸、苹果酸和柠檬酸的同化作用,并为利用这些底物生产生物质提供氮源。当EDTA耗尽或至少大量降解时,菌株VKM B - 2445开始利用主要的非生长底物。
