Metabolic deficiences revealed in the biotechnologically important model bacterium Escherichia coli BL21(DE3). [PDF]
The Escherichia coli B strain BL21(DE3) has had a profound impact on biotechnology through its use in the production of recombinant proteins. Little is understood, however, regarding the physiology of this important E. coli strain. We show here that BL21(

A programmable CRISPR/Cas9-based phage defense system for Escherichia coli BL21(DE3). [PDF]
Abstract Escherichia coli BL21 is arguably the most popular host for industrial production of proteins, and industrial fermentations are often plagued by phage infections. The CRISPR/Cas system is guided by a gRNA to cleave a specific DNA cassette, which can be developed into a highly efficient programable phage defense system.

Tailoring Escherichia coli BL21 (DE3) for preferential xylose utilization via metabolic and regulatory engineering. [PDF]
Abstract Xylose is the most abundant pentose in nature. However, it is usually obtained in mixtures with glucose, leading to carbon catabolite repression in many microorganisms. Among E. coli lineages, significant metabolic and regulatory differences exist, requiring distinct metabolic engineering strategies to develop a xylose-

Characterisation of the bacterial biosensor GMG in E-coli BL21 (DE3)
In this work, a gold biosensor has been constructed and characterised in Escherichia coli (E. coli). Though gold biosensors have been previously reported, a NOT gate gold biosensing genetic circuit was constructed using an orthogonal inverter system as ...

Isolation and characterization of the E. coli membrane protein production strain Mutant56(DE3) [PDF]
Membrane protein production is usually toxic to E. coli. However, using genetic screens strains can be isolated in which the toxicity of membrane protein production is reduced, thereby improving production yields. Best known examples are the C41(DE3) and
