Cloning and sequencing of a poly(DL-lactic acid) depolymerase gene from Paenibacillus amylolyticus strain TB-13 and its functional expression in Escherichia coli

Article Abstract:

Research has been conducted on gene encoding poly(DL-lactic acid) depolymerase from Paenibacillus amylolyticus strain TB-13. The authors report the cloning and overexpression of this gene, and demonstrate that purified recombinant poly(DL-lactic acid) depolymerase tends to degrade different biodegradable polyesters.

High level production of porphyrins in metabolically engineered Escherichia coli: systematic extension of a pathway assembled from overexpressed genes involved in heme biosynthesis

Article Abstract:

The authors have investigated the overproduction of Escherichia coli porphyrins and porphyrinogens. They report that this overproduction has been caused by the extention of heme biosynthetic pathway consisting of genes obtained from different microorganisms.

n-Hexane sensitivity of Escherichia coli due to low expression of impl ostA encoding an 87 kDa minor protein associated with the outer membrane

Article Abstract:

Research has been conducted on Escherichia coli resistance to n-hexane. The authors suggest that the gene product, an 87 kDa minor protein associated with outer membrane, reduces n-hexane influx.
