Expression of a Clostridium thermocellum endoglucanase gene in Lactobacillus plantarum.

abstract：:Spontaneous vegetable fermentations, with their rich flavors and postulated health benefits, are regaining popularity. However, their microbiology is still poorly understood, therefore raising concerns about food safety. In addition, such spontaneous fermentations form interesting cases of man-made microbial ecosystem...
