- 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
