Yeast facultative anaerobic organism

It is a unicellular fungus, which is usually distributed in high-sugar and acidic environments, such as the surface of vegetables and fruits and the soil of vegetable gardens and orchards. Under aerobic conditions, carbohydrates are decomposed into carbon dioxide and water; In the absence of oxygen, sugar will be decomposed into carbon dioxide and alcohol.

lactobacillus

Refers to a spore-free, Gram-positive bacterium whose main product of fermented sugar is lactic acid. Bacteria are often arranged in chains. Homotypic lactic acid fermentation is called lactic acid fermentation, and heterotypic lactic acid fermentation is called lactic acid fermentation. Besides lactic acid, there are more substances such as acetic acid, ethanol and CO2. There are microaerobic bacteria and obligate anaerobic bacteria.

actinomyces

Actinomycetes are a group of prokaryotes. Through asexual spores and bacterial division and reproduction. Most of them are heterotrophic aerobic bacteria. Some species can decompose complex organic matter such as cellulose at high temperature. It is widely distributed in nature, most of which are saprophytic and a few are parasitic. Produce a variety of antibiotics.
