Polyhydroxybutyrate-enhanced transformation of log-phase Escherichia coli.

Relationship of cell surface hydrophobicity with biofilm formation and growth rate: A study on Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli

Objective(s): This study was designed to determine the relationship of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli isolates in multispecies biofilms and their individual phenotypic characters in biofilm consortia. Materials and Methods:  The subject isolates were recovered from different food samples and identified on the basis of growth on differential and selective med...

Enhanced production of polyhydroxybutyrate by multiple dividing E. coli

BACKGROUND Most bacteria are grown in a binary fission way meaning a bacterial cell is equally divided into two. Polyhydroxyalkanoates (PHA) can be accumulated as inclusion bodies by bacteria. The cell division way and morphology have been shown to play an important role in regulating the bacterial growth and PHA storages. RESULTS The common growth pattern of Escherichia coli was changed to m...

Enhanced Expression of Recombinant Activin A in Escherichia coli by Optimization of Induction Parameters

Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...
