As an attractive host,Bacillus subtilis is a nonpathogenic bacterium that can efficiently secrete large quantities of a variety of enzymes into the culture medium. Such secretion facilitates further purification steps and simplifies product recovery. Many Processes concerning production technology and large-scale fermentation using this bacterium is very well acquainted. The major advantage of B. subtilis is that it does not produce LPS. And it has no significant bias in codon usage which is considered as an added advantage. However, some problems could be found down the pipeline, such as instability of plasmids, reduced or non-expression of the protein of interest, and even production of extracellular proteases which recognize and degrade heterologous proteins. Our talented scientists have extensive experience to help you solve all your problems.
