乳酸菌..how to reproduction? (use chinese to respond)

Lactobacillus is a genus of Gram-positive facultative anaerobic bacteria. They are a major part of the lactic acid bacteria group, named as such because most of its members convert lactose and other sugars to lactic acid. They are common and usually benign. In humans they are present in the vagina and the gastrointestinal tract, where they are symbiotic and make up a large portion of the gut flora. Many species are prominent in decaying plant material. The production of lactic acid makes its environment acidic which inhibits the growth of some harmful bacteria.

Some Lactobacillus species are used industrially for the production of yogurt, cheese, sauerkraut, pickles, and other fermented foods, such as silage. Sourdough bread is made using a "starter culture" which is a symbiotic culture of yeast and lactic acid bacteria growing in a water and flour medium. Korean kimchi is also made using lactic acid fermentation techniques. Many lactobacilli are unique among living things as they do not require iron for growth and have an extremely high hydrogen peroxide tolerance. Lactobacilli, especially L. casei and L. brevis, are some of the most common beer spoilage organisms.

Several members of the genus have had their genome sequenced.

Many lactobacilli are unusual in that they operate using homofermentative metabolism (that is, they produce only lactic acid from sugars) and are aerotolerant despite the complete absence of a respiratory chain. This aerotolerance is manganese-dependent and has been explored (and explained) in Lactobacillus plantarum.

天然乳酸菌飼料添加劑是通過微生物發酵，真空冷凍乾燥製成的活菌凍干制劑，其中含多種天然乳酸菌、酶制劑和微量養素。活菌含量高達每克菌粉乳酸菌超過1000億，由於採用了特殊的年產工藝和配方工藝，乳酸菌有著良好的存活性和穩定性。在10℃以下保存，有效期為12個月。在電冰箱已相對普及的情況下，已具備推廣條件。

天然乳酸菌飼料添加劑用於秸桿青貯時體現六大優勢：

１縮短髮酵週期，快速降低PH值。
２抑制腐敗細菌的生長繁殖，解決了飼料的腐敗問題。
３抑制酵母菌和黴菌的生長繁殖，避免了飼料因發熱而消耗能量，也解決了飼料的霉變問題。
４降解纖維素並轉化為乳酸，提高了飼料的利用率。
５保持了飼料的鮮嫩汁液和營養成分，提高了飼料的適口性和消化率。
６明顯減少流出物，降低了飼料干物質的損失。
