Display of a β-mannanase and a chitosanase on the cell surface of Lactobacillus plantarum towards the development of whole-cell biocatalysts
BACKGROUND Lactobacillus plantarum is considered as a potential cell factory because of its GRAS (generally recognized as safe) status and long history of use in food applications. Its possible applications include in situ delivery of proteins to a host, based on its ability to persist at mucosal surfaces of the human intestine, and the production of food-related enzymes. By displaying differen...
متن کاملTuning constitutive recombinant gene expression in Lactobacillus plantarum
BACKGROUND Lactobacillus plantarum constitutes a well-recognized food-grade system for the expression of recombinant proteins in the field of industrial and medical biotechnology. For applications in vivo or in biotechnological processes, the level of expression of e.g. antigens or enzymes is often critical, as expression levels should be of a certain effectiveness, yet, without putting too muc...
متن کاملExpression of mannanase gene from Bacillus circulans NT 6.7 in Escherichia coli and Lactobacillus plantarum
The mannanase gene of B. circulans NT 6.7 was cloned and expressed in Escerichia coli and food-grade Lactobacillus plantarum expression system. B. circulans NT 6.7 mannanase gene consisted of 1,083 nucleotides encoding 360 amino acid residues which belonging to glycosyl hydrolase family 26. In E. coli system, mannanase gene was cloned into pET21d and expressed in E. coli BL21* (DE3). Beta-manna...
متن کاملAntibiofilm potential of Lactobacillus plantarum spp. cell free supernatant (CFS) against multidrug resistant bacterial pathogens
Biofilm formation is a major determinant factor in development of bacterial infections. In addition, bacteria embedded in a biofilm are more resistant to antimicrobials and thus the ability of bacteria to persist and grow in a biofilm seems to be the major factor for pathogenesis and therapeutic failure. In the current study, a Lactobacillus plantarum spp was isolated from Siahmazgi cheese, tra...
متن کاملFrom mannan to bioethanol: cell surface co-display of β-mannanase and β-mannosidase on yeast Saccharomyces cerevisiae
BACKGROUND Mannans represent the largest hemicellulosic fraction in softwoods and also serve as carbohydrate stores in various plants. However, the utilization of mannans as sustainable resources has been less advanced in sustainable biofuel development. Based on a yeast cell surface-display technology that enables the immobilization of multiple enzymes on the yeast cell walls, we constructed a...
