The present disclosure relates generally to bacterial delivery vehicles for use in efficient transfer of a desired payload into a target bacterial cell. More specifically, the present disclosure relates to bacterial delivery vehicles with desired host ranges based on the presence of a chimeric receptor binding protein (RBP) composed of a fusion between the N-terminal region of a RBP derived from a lambda-like bacteriophage and the C-terminal region of a different RBP.

This disclosure describes compositions and methods for enhanced production of enduracidin in genetically engineered strains of Streptomycesfungicidicus. In particular, the present disclosure describes the genetic manipulation of regulatory genes orf24 and orf18 associated with the enduracidin (enramycin) biosynthesis gene cluster from Streptomyces fungicidicus to generate vector constructs and recombinant strains producing greater yields of enduracidin.

A method for producing a fibroin-like protein is provided. A fibroin-like protein is produced by a method of culturing Escherichia coli having a gene encoding the fibroin-like protein in a medium, inducing expression of the gene encoding the fibroin-like protein, and collecting the fibroin-like protein, wherein accumulation of an organic acid at the time of inducing the expression is reduced, and wherein the gene is expressed under control of a tryptophan promoter.

Disclosed herein are an expression vector capable of expressing myrcene, an Escherichia coli strain transformed with the vector and having improved capability of producing myrcene and a method for producing myrcene and a method for recycling glycerol using the same. In an aspect, the transformed Escherichia coli strain of the present disclosure can produce myrcene with high purity on a large scale using glycerol or glucose as a carbon source. Also, the Escherichia coli strain of the present disclosure is economical and environment-friendly because it can produce high value-added myrcene using waste glycerol as a carbon source. In addition, the strongly volatile myrcene can be produced and isolated at the same time.
