查询词典 bacterium

For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.

分别将菌株接入含有不同矿粉的培养基中培养，检测其在有氮、无氮培养基中荚膜多糖含量的变化，并在以钾长石和黑云母为矿源的情况下，比较研究了菌株在有氮、无氮培养基中对矿物的风化能力，通过一系列的实验，证实胶质芽孢杆菌在生长过程中所分泌的粘稠胞外聚糖可帮助细菌有效黏附在矿物表面，形成细菌-矿物复合体，并改变及维持该复合体内部的微环境，有助于该菌的解钾作用，而且细菌分泌的胞外蛋白质在该菌对含钾硅酸盐矿物的解钾作用过程中发挥重要作用；将胶质芽孢杆菌接入以钾长石和黑云母为矿源的有氮、无氮培养基中培养，检测到该菌碳酸酐酶活性的变化，并进行批量发酵后小分子酸性分泌产物的提取、分离、纯化与鉴定等方面的研究，结果表明，该菌可产生2-羟基苯甲酸，4-羟基苯乙酸，4-羟基苯甲酸甲酯等小分子物质。
