摘要
研究了厌氧、加还原剂和好氧条件下运动发酵单胞菌ＡＴＣＣ２９１９２和ＡＴＣＣ３５０００的生长速率及生长量。在复合培养基不加还原剂的厌氧条件下，生长速率最高，２９１９２和３５０００分别为０．３０９ｈ￣（－１）和０．４７２ｈ￣（－１）。２９１９２对还原剂和氧气比３５０００更为敏感。结果表明，还原剂还原力愈强，抑制生长的效应愈强；还原剂随浓度升高，毒性亦增强。
This research investigated the effects of anaerobic conditions, reducingagents and aeration on Zymomonas mobilis ATCC 29192 and ATCC 35000. In stirred batchcultures with a 2% glucose, 1% peptone, and 1% yeast extract medium sparged withnitrogen, 29192 and 35000 had greatest growth rates of 0.309/h and 0.472/h, respectively.29192 was more sensitive towards the reducing agents and oxygen than 35000. The strongerthe reducing power, the more inhibitory the agent was. These agents tested caused varyingdegrees of toxicity. Higher levels of agents were always more toxic.
