We isolated a mutant 311-60 of Strep-tomyces hygroscopicus var. jinggangensis which was showed resistive to phosphate and produced more Jingsimycin when the parent strain was treated by UV and added

通过紫外线处理和高浓度磷酸盐选择分离到静丝霉素的耐磷高产突变株311-60,在10到30mM磷酸盐条件下抗生素的积累明显地超过了亲本菌株,在正常发酵条件下超产可达45.2%: 突变株203-4的菌落形态与亲本菌株差异较大,在10到30mM磷酸盐条件下其静丝霉素产量超过亲本,亦属于耐磷突变株。

Biosynthesis of polyhydroxyalkanoates (PHAs) by Ralstonia eutropha with single and mixed short-chain- length organic acids as carbon sources was studied. Different initial concentrations of carbon and nitrogen sources in the media played an important role in the output of PHAs. Under the same concentration of carbon sources, a lower concentration of nitrogen was more propitious to the biosynthesis of PHAs. The concentrations of volatile organic acids at 8 g/L and concentrations of (NH4)2SO4 at 0.3 g/L were probably...

Biosynthesis of polyhydroxyalkanoates (PHAs) by Ralstonia eutropha with single and mixed short-chain- length organic acids as carbon sources was studied. Different initial concentrations of carbon and nitrogen sources in the media played an important role in the output of PHAs. Under the same concentration of carbon sources, a lower concentration of nitrogen was more propitious to the biosynthesis of PHAs. The concentrations of volatile organic acids at 8 g/L and concentrations of (NH4)2SO4 at 0.3 g/L were probably the most appropriate for the PHAs fermentation. Among the four kinds of short-chain-length organic acids for experiments, lactic acid was used up the first, acetic acid, propionic acid and butyric acid successively. Furthermore, acetic acid was produced when propionic acid was used as carbon source for the biosynthesis of PHAs by Ralstonia eutropha, which was never reported before. Interestingly, when mixed acids were used as carbon sources at the levels of 5 L fermenter and 500 ml flask to biosynthesize PHAs, the 5 L fermenter excelled the latter almost in all technical indexes.

研究了真氧产碱杆菌利用单一以及混合短链有机酸作为碳源进行聚羟基烷酸酯(PHAs)的生物合成. 不同的碳氮浓度比对产物的形成有较大影响;在同样的碳源浓度下,较低氮源浓度更加有利于产物的合成;当短链有机酸浓度为8 g/L、硫酸铵浓度为0.3 g/L时对PHAs的合成最为有利.在4种短链有机酸分别单独用作碳源时,乳酸的消耗速度最快,其次为乙酸、丁酸以及丙酸;在单酸发酵条件下,丁酸的PHAs产量最高(2.72 g/L). 通过比较摇瓶以及5 L罐水平的混合酸发酵发现,发酵罐中的各项发酵指标均优于摇瓶. 研究还发现,真氧产碱杆菌在利用丙酸为碳源进行产物合成时,在发酵后期还伴随有乙酸产生.

The effects of Bacillus cereus on the growth of Gluconobacter oxydans and 2-keto-L-gulonic acid (2-KGA) formation during two-step fermentation process of vitamin C were investigated. It is shown that under co-culture conditions of the two strains, comparing to single strain fermentation with G. oxydans , as much as about 5 times of cells of G. oxydans , 2~3 times 2-KGA and 2~3 times of bioconversion activities were formed, suggesting that the improved 2-KGA formation may caused only by stimulation of B. cereus...

The effects of Bacillus cereus on the growth of Gluconobacter oxydans and 2-keto-L-gulonic acid (2-KGA) formation during two-step fermentation process of vitamin C were investigated. It is shown that under co-culture conditions of the two strains, comparing to single strain fermentation with G. oxydans , as much as about 5 times of cells of G. oxydans , 2~3 times 2-KGA and 2~3 times of bioconversion activities were formed, suggesting that the improved 2-KGA formation may caused only by stimulation of B. cereus on the growth of G. oxydans . The results of bioconversion with resting cells of G. oxydans also showed that neither the culture supernatant nor the cell-free extracts indicated any obvious clue of direct effect on the biotransformation activity.

通过分析维生素C二步发酵过程中活菌数、产酸量、pH、糖酸转化活力等 ,研究了蜡状芽孢杆菌 (俗称大菌 )对氧化葡糖杆菌 (俗称小菌 )生长和产酸的影响。结果表明 ,在大菌存在情况下 ,小菌的活菌数约为单菌培养条件下的 5倍 ,产酸量为单菌培养条件下的 2~ 3倍 ,糖酸转化活力为单菌培养条件下的 2~ 3倍 ,提示在混合菌发酵条件下大菌仅仅是通过刺激小菌的生长而促进小菌产酸。用小菌休止细胞进行的糖酸转化实验结果也表明 ,无论大菌的发酵上清液还是破碎的菌体 ,都未发现对小菌产酸产生直接影响。
