中文拼音 [róngyuánjūnzhū]
溶源菌株
英文
lysogenic strain-
In this study a microbial system for biphenyl biodegradation is set up in order to investigate the effects of surfactants on biodegradation of hydrophobic organic compounds. four strains which can grow on biphenyl as the sole carbon and energy sources are selected out, in which alcaligenes eutrophus dj1 and pseudomonas sms02 are chosen as degradation strains. after studing the bioavailability of three nonionic surfactants ( op - 10, tween - 80, and triton x - 100 ), they are added into the biodegradation system of biphenyl
為了考察表面活性劑對疏水性有機污染物生物降解的影響，本論文選擇聯苯作為模擬研究體系，篩選、馴化得到四株可利用聯苯作為碳源生長的菌株；考察了聯苯降解菌株對三種非離子表面活性劑op - 10 、 tween - 80 、 tritonx - 100的生物可利用性；用高效液相色譜法測定了非離子表面活性劑對聯苯的增溶曲線；較系統地研究了加入非離子表面活性劑對聯苯生物降解速率的影響。Three phenanthrene - degrading bacteria were isolated from soil samples contaminated by oil, which are capable of using phenanthrene as sole carbon and energy sources, and were identified to be belonged to sphingomonas, strain zx4 as s. paucimobilis, strain zx6 as s. aromaticivorans and strain eva 17 not being identified to species, respectively, based on the results of physio - biochemical tests and the phylogenetical analyses of 16s rdna sequence
實驗結果分述如下： 1 、本研究從石油污染土壤中分離到3株菲降解細菌（ zx4 、 zx6和eva17 ） ，它們都能以菲為唯一碳源和能源生長。經鑒定3菌株都歸于鞘氨醇單胞菌屬（ sphingomonas ） ，其中zx4菌株為少動鞘氨醇單胞菌（ sphingomonaspaucimobolis ） ， zx6菌株為溶芳烴鞘氨醇單胞菌（ sphingomonasaromatics ） ， eva17菌株比較獨特，尚未能鑒定到種。From the result of electrophoresis, it known that the different components of the enzyme system were expressed cooperatively. in order to study the essence of cellualase induction of different carbon sources, the extracellular, plasm - membrane - bound and intracellular cellulases were made to transform different soluble inducers, and the productions were analyzed by gc chromatogram. the results supported the assumption that cellobiose acted as the direct inducer or the metabolic analogue, b - gentiobiose from cellobiose acted as the true inducer through different metabolism ways in different strains
制備細胞膜外、細胞膜、細胞內纖維素酶，用定位於這三部位的纖維素酶分別轉化底物，然後進行氣相色譜定性分析，從而探討了不同碳源之間的誘導本質，結果認為不可溶的胞外纖維素以纖維二糖為橋梁，遵循不同的代謝途徑，直接或間接地誘導了兩株不同真菌纖維素酶的合成。
