    摘要: The present disclosure is generally related to compositions and methods for constructing and obtaining Bacillus sp. host cells (strains) having enhanced protein production phenotypes. Certain embodiments of the disclosure are therefore related to genetically modified Bacillus sp. cells derived (obtained) from parental Bacillus sp. cells (e.g., such as parental Bacillus cells expressing/producing a protein of interest). Thus, certain embodiments are directed to modified Bacillus sp. cells expressing/producing an endogenous protein of interest, or a heterologous protein of interest, wherein the modified Bacillus sp. cell comprises a genetic modification of a yitMOP operon, a combined genetic modification of a yitMOP operon and a sdpABC operon, a genetic modification of a yitM gene and the like, wherein the modified Bacillus sp. cells produce an increased amount of the POI relative the parental cells from which they were derived (i.e., when grown/cultivated/fermented under identical conditions).

    摘要: The present disclosure is generally related to compositions and methods for constructing and obtaining Bacillus licheniformis cells having increased protein production phenotypes. Thus, certain embodiments are related to modified B. licheniformis cells derived from parental B. licheniformis cells. Certain embodiments are related to modified B. licheniformis cells comprising a modified rghR locus. Certain embodiments are related to modified B. licheniformis cells having a modified rghR locus and comprising an increased protein productivity phenotype. In certain other embodiments, modified B. licheniformis cells having a modified rghR locus produce a reduced amount of red pigment. In certain other embodiments, modified B. licheniformis cells comprise an increased protein productivity phenotype and produce a reduced amount of red pigment.
