WebEach mutant constructed should be assigned a strain number. Strain numbers usually consist of two to three capital letters designating the lab where they were constructed and a serial numbering of the strains in a central laboratory collection. Every mutation should be assigned a name that corresponds to a particular gene or phenotype, and an ... The construction of strain GH16 was achieved by knocking out five genes encoding extracellular proteins and an operon from Bacillus subtilis G423. We then analyzed the amount of protein impurities in the γ-PGA produced by the resulting strain GH16/pHPG, which decreased from 1.48 to 1.39%. See more The tasA-yqxM operon, lip, epr, bpr, ylqB and yweA genes were successively knocked out from G423 strain and the deficient strain GH16 … See more The flagellar protein deficient strain GH17 was constructed by deleting the first 30 genes of the fla-che operon in GH16 strain, while the terminal ylxL gene was retained. The … See more Approximately 1.0% of the proteins still remained in the γ-PGA extracted from fermentation broth of GH18/pHPG strain. Therefore, advanced … See more A total of 26.1 kb of PBSX sequences, from genes xkdB to xlyA, were deleted from GH17 strain, resulting in strain GH18. We found that the … See more
