短乳杆菌常在传统发酵食品中可分离得到，如泡菜，干酪等，微耗氧，属于异型

Lactobacillus brevis can often be isolated from traditional fermented foods, such as kimchi, cheese, etc. It is slightly oxygen-consuming and belongs to heteromorphic lactic acid fermentation. It is rod-shaped with round ends, 0.7-1.0×2.0-4.0μm in size, and often long. Rod-shaped, the colony is rough, flat and almost transparent. It produces lactic acid, ethanol, acetic acid and other mixtures through the phosphoketolase (PK) pathway. Bifidobacteria often use this approach, which can simultaneously utilize five-carbon sugars and Six-carbon sugar, without carbon metabolism inhibition effect (Jae-Han Kim et al. 2009), more than 90% of Lactobacillus brevis can utilize arabinose, fructose, glucose, gluconic acid, maltose, melibiose, ribose, 11 -89% of Lactobacillus brevis can use esculin, galactose, lactose, sucrose, xylose, raffinose.

Lactobacillus brevis is often isolated from traditional fermented foods, such as pickles, cheese, etc. it consumes little oxygen and belongs to heterotypic lactic acid fermentation. It is rod-shaped, with a round end and a size of 0.7-1.0 × 2.0-4.0 μ m. Bifidobacteria often use this pathway to produce lactic acid, ethanol, acetic acid and other mixtures. They can utilize both pentose and hexose, and do not have the effect of carbon metabolism repression (Jae Han Kim et al. 2009), More than 90% of Lactobacillus brevis could utilize arabinose, fructose, glucose, gluconic acid, maltose, cellobiose and ribose, and 11-89% could utilize aescin, galactose, lactose, sucrose, xylose and raffinose.<br>

It produces lactic acid, ethanol, acetic acid, etc. through the way of ethyl ketolase phosphate (PK) It can utilize five-carbon sugar and six-carbon sugar at the same time, and has no carbon metabolism repression effect (Jae-Han Kim et al. 2009). More than 90% of Lactobacillus brevis can utilize arabinose, fructose, glucose, gluconic acid, maltose, melibiose and ribose, and 11-89% of Lactobacillus brevis can utilize escin, galactose, lactose, sucrose, xylose and cotton
