Sulfid also can be regarded as a marker of the action of sulfur bacteria. 8 ) based on research results, author postulated that early generation of hydrocarbons is closely related to the action of sulfur bacteria. many kind of algae such as dinoflagellates, diatom, prynesiophytes etc have rich biological lipids which has lower polymerization
6 、從未熟一低熟源巖生烴組分及其演化、可溶有機質轉化生烴等方面，探討了未熟一低熟油的形成機制，提出本區未熟一低熟油氣的形成是低活化能的富氫腐泥組分受到硫細菌早期低溫降解作用的結果。In order to efficiently improve the stability of the apparatus, a dual - optical detection circuit was adopted. to eliminate the multiple scattering effects on transmittance measurements, the range of the transmittance was limited to 70 - 100 % by adjusting the width of the light flow cell and changing the intensity of the incident light through regulating the load voltage of the laser light source. moreover, the data acquisition software was programmed in microsoft visual bas
通過調節激光光源負載電壓改變光強度及調摘要整檢測池的寬度，消除了多重散射對透光率的影響，將透光率的變化范圍控制在滿足beer1a毗ert定律的范圍內工將溫度、溶液密度和透光率信號經模數轉換，並用microsoftvisualbasic語言編寫的數據採集軟體，實現了實驗過程中各被測量的自動連續採集。Using pcr technology, a 2. 4kb dna fragment, part of tryptopanase operon, containing a promoter, a regulator gene tnac located downstream of the promoter and a desired tryptopanase gene tnaa which can be expressed by the promoter from e. coli k - 12, was cloned to pmd18 - t vector. the dna sequence is the same as which was published on science
為了證明質粒上的基因能表達出有活性的色氨酸酶，將這個dna片段克隆到pet28c質粒的bamhi和hind位點上，使該片段受t7rna聚合酶的啟動子控制，然後轉化噬菌體de3的溶源菌bl21 （ de3 ） 。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。分享友人
