    摘要介紹了石煤提釩傳統工藝的改進以及酸法萃取、無鹽焙燒酸浸萃取、氧化焙燒堿浸等幾種從石煤無污染提取五氧化二釩的工藝流程，上述工藝不但生產過程無環境污染，釩的回收率還大有提高，是很有前途的清潔生產工藝。
  2. Extraction, isolation and purification of alkali - soluble polysaccharide from leaf mustard

    堿溶性包心芥菜多糖的分離純化研究
  3. So some methods suitable to large plasmid extraction, including lysis by sds and a method from a literature, were used to try to extract the large plasmid from the strain cell. the lysis reactions in these two methods are gentle, so the large plasmid cannot be injured in the lysis process, opposite to lysis by alkali. it would be helpful to keep the integrality of the large plasmid during the extraction

    因此我們採用了適合於大質粒提取的sds法，和文獻中應用於硝基苯降解性質粒的提取方法，來嘗試對菌株細胞進行質粒提取，這兩種方法裂解反應溫和，不會像堿裂解法那樣，在裂解過程中損壞質粒，可以實現質粒提取的完整性。
  4. The plasmid extraction from wild strains needs an appropriate method. first, lysis by alkali was used to extract plasmid from strain pseudomonas xn - 1. but the expected result had not been got, and a lot of cracked plasmid dna fragments were got only

    對於野生菌株的質粒提取，需要選擇合適的提取方法，我們首先採用了細菌細胞質粒提取常用的堿裂解法，但是未取得理想的效果，只得到了許多破碎的質粒dna片段。
  5. The bioactive strain ' s fermentation product was isolated and purified primarily using methods of solvent extraction, acid - alkali extraction, ab - 8 macropore absorption chromatography, 1 x 007 positive ion exchange chromatography, the result showed the purification product has prominent bioactivity inhibit staphalococcus aureus

    中國熱帶農業科學院、華南熱帶農業大學2003屆碩士研究生採用有機劑抽提法、酸堿抽提法、大孔吸附樹脂柱層析和陽離子交換樹脂柱層析等方法對hsl 306菌株發酵產物進行了初步分離純化。
  6. Three different extraction methods ( cold methanol, hot ethanol and alkali extraction ) were analyzcd and compared using the direct infusion electrospray ionization - mass spectrometry ( esi - ms ) as the evaluation standard

    本研究以特定厭氧條件下培養的大腸桿菌為研究對象，以電噴霧質譜直接進樣測定為評價標準，比較並分析了冰甲醇、熱乙醇和堿抽提3種抽提方法。
