- Photochemical reduction of plastoquinone by ascorbic acid inethanol was sensitized with some derivatives of chlorophyll.The order of effectiveness was as follows: allomerized chlorophylla > chlorophyllin a > chlorophyll a > chlorophyll b> pheophytin a.
- Quenching of the fluorescence of chlorophylla by plastoquinonewas observed. The quenching constant calculatedwas 71 litreper mole.

甘露醇微生物转化的研究 总被引:4,自引:0,他引:4
研究了碳源、pH及添加西红柿汁对发酵乳杆菌生产甘露醇的影响。结果表明:以果糖为碳源,浓度为150g/L时,Lactobacillus Ferm101能够生产相当量的甘露醇而无山梨醇产生。在培养过程中通过调控pH并添加西红柿汁可使甘露醇收率达到51%. 相似文献

When myosin is dehydrated it becomes insoluble. The number of detectable SH groups in myosin coagulated by dehydration is the same as in native soluble myosin. In this respect coagulation by dehydration differs from coagulation brought about in any of the other ways now known, but resembles the coagulation that occurs in muscle during rigor and in the egg after fertilization. 相似文献
