Based on reviewing key techniques for bioethanol production from lignocellulose, advantages and disadvantages of various physical, chemical and biological pretreatments, along with the latest methods, were analyzed. Moreover, the characteristics of many kinds of microbes, such as their thermotolcrance and ability of pentose's usage, and the widely-used fermentation modes are also summarized in this review to provide some new ideas for ethanol production from lignocellulose.

His experiments supported the germ theory of disease also reducing mortality from puerperal fever and he created the first vaccine for rabies. He was best known to the general public for inventing a method to stop milk and wine from causing sickness - this process came to be called pasteurization.

他提出了以微生物代谢活动为基础的发酵本质新理论，发明了沿用至今的巴氏消毒法，成功地拯救了法国处于困境中的酿酒业、养蚕业和畜牧业；他发现传染病的微菌在特别的培养之下可以减轻毒力，从而发明了鸡霍乱疫苗、狂犬病疫苗，建立起了细菌理论。

And thiamine was confirmed to be the most important factor affecting the production of pyruvic acid.

优化后7L罐中发酵的产量、生产强度和产率分别达到80.51g/L、1.83g/Lh和0.69g/g，比对照提高了44.36%、57.48%和22.78%，达到或高于已报道的同类菌株的国际最佳研究结果。

While traditional fabrication technique is: raw material infusion, prefractionation, stewing, redistillation, taking out and cooling, yeast adding, barrel filling and cultivating, water feeding and grains mixing, barrel filling and fermenting, distilling, final spirits or alcohol.

而传统酿造工艺为：原料浸泡、初蒸、焖粮、复蒸、出甑摊凉、加曲、装桶培菌、加水配槽、装桶发酵、蒸馏、成品酒或酒精。

In this paper, it was analyzed that the change of organic substances and bacteria growth in fermenting liquid during the retting of flax stem by rapid retting strain No.

在实验室条件下，利用亚麻脱胶菌Ym68'，对亚麻原茎进行快速脱胶试验，定期测定了发酵液中的各项指标。

EPS composition fermented with strain 7 and Streptococcus thermophilus together was stable and consists of glucose, galactose and rhamnose, but EPS with normal starters of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus does not consist of rhamnose.

产粘7号菌在诱变前后与不产粘嗜热链球菌共同发酵产生的EPS单糖组成不变，都是由葡萄糖、半乳糖和鼠李糖组成；而不产粘嗜热链球菌与不产粘保加利亚乳杆菌产生的EPS不含鼠李糖，只有葡萄糖和半乳糖。

As biosurfactant is a secondary metabolizing product, traditional methods can't access the processing easily, so they focus mainly on screening high productive strains and the effects on production by various fermentation conditions.

但是，由于其是次生代谢产物，传统方法主要是进行高效菌株的筛选，以及研究不同发酵条件对其产量的影响。
