To investigate the mechanisms of biohydrogen production by anerobic fermentation of solid organic waste, gas chromatography is used to analysis the biogas and volatile fatty acid in anaerobic bio-reactor. Firstly, the ability of hydrogen production by digested sludge from the West Lake, Enteobacter aerogences, digested sludge from sewage farm, the fluid of methane pool and dejecta have been studied. The rule of the ability of hydrogen production by different bacteria under different control condition. Simultaneity, the importance of the synergistic effect on hydrogen production has been proved.

本文首先选用西湖底的厌氧活性污泥、产气肠杆菌、污水处理厂的淤泥、沼气池发酵液以及猪粪等不同菌群对废弃食物——马铃薯进行厌氧发酵产氢特性实验研究，得到马铃薯在各不同菌群及工况下的发酵产氢能力，同时发现产氢菌间的协同作用很重要，在控制好发酵条件的情况下，产氢菌群发酵通常会好于单一产氢菌的发酵。

Factors for the content of higher alcohols include composition of malt liquid, yeast species and its inoculative use level, and fermentation conditions (fermentation temperature, fermentation methods, fermentation degree etc.).

影响高级醇含量的因素有酵母菌种及接种量、麦汁成分和发酵工艺(如发酵温度、发酵方法、发酵度等)。

4Mm harvested in preculture, is the best. In this form, Rhizopus oryzae R1021 produced most L-lactic acid (76. 62g/L), the pellet size in production medium in flask and fermentor are 1. 9mm and 2. 6mm, respectively, and its L-lactic acid productivity reached or exceeded that of the immobilized cell with polyurethane foam. The produced L-lactic acid and the yield of L-lactic acid based on the total glucose and the productivity are above 74g/L and 74% and 2. 69g/L h, respectively, in 7 batches repetitive fermentation in fermentor, and the size of pellets remain 2. 6mm～3. 4mm.

摇瓶种子培养获得的菌球直径为1.4mm时，这种大小的菌球产酸最高，为76.62g/L；研究表明以直径1.4mm的菌球为种子，在摇瓶发酵和发酵罐发酵中菌球大小分别为1.9mm和2.6mm；这种菌球的产酸水平最高，可以达到甚至超过聚氨酯泡沫载体固定化细胞发酵乳酸的水平；在反复7批次发酵罐发酵过程中，菌球的大小始终保持在2.6mm～3.4mm之间，L-乳酸产量、得率和生产能力分别保持在74g/L、74％和2.69g/L h以上。

The methanol contents of carambola wine fermented from fresh and frozen carambola juice were 33 and 74 ppm respectively. The alcohol content, soluble solid, specificity gravity, pH and titrable acid are almost the same during the fermentation of carambola juice and puree, the methanol content of the must would increase as the fermentation progressing. The methanol content of the wine fermented from carambola juice and carambola puree were 74 and 256 ppm respectively, so the separation of the pulp from carambola puree can decrease the methanol content efficiently in carambola winemaking.

新鲜及冷冻杨桃汁经发酵后，甲醇含量分别为33及74 ppm，杨桃汁与杨桃泥在发酵期间其酒精度、可溶性固形物、比重、pH、可滴定酸的变化情形相似，而甲醇则随著发酵时间增加而增加，杨桃汁及杨桃泥所酿造之杨桃酒其甲醇量分别为74 及256 ppm，结果显示杨桃发酵前汁渣分离将可有效降低杨桃酿造酒中甲醇含量。

Through the research of stability of the fermentation broths of actinomycete strain HJ1-2 to heat, acid. alkali and light, it had a stable activity to heat, acid and UV, but unstable to alkali.
