A markerless gene replacement method was adapted by combining a suicide plasmid, pEX18Tc, with a counterselectable marker, the upp gene encoding uracil phosphoribosyltransferase (UPRTase), for the medium-chain length polyhydroxyalkanoates (PHA(MCL))-producing strain Pseudomonas mendocina NK-01. An NK-01 5-fluorouracil (5-FU) resistant background strain was(More)
Agricultural soils are often cocontaminated with multiple pesticides. Unfortunately, microorganisms isolated from natural environments do not possess the ability to simultaneously degrade different classes of pesticides. Currently, we can use the approaches of synthetic biology to create a strain endowed with various catabolic pathways that do not exist in(More)
Agricultural soils are usually co-contaminated with organophosphate (OP) and pyrethroid pesticides. To develop a stable and marker-free Pseudomonas putida for co-expression of two pesticide-degrading enzymes, we constructed a suicide plasmid with expression cassettes containing a constitutive promoter J23119, an OP-degrading gene (mpd), a(More)
We determined the complete genome sequence of a soil bacterium, Streptomyces albulus NK660. It can produce ε-poly-l-lysine, which has antimicrobial activity against a spectrum of microorganisms. The genome of S. albulus NK660 contains a 9,360,281-bp linear chromosome and a 12,120-bp linear plasmid.
The twin-arginine translocation (Tat) pathway exports folded proteins across the cytoplasmic membranes of bacteria and archaea. Two parallel Tat pathways (TatAdCd and TatAyCy systems) with distinct substrate specificities have previously been discovered in Bacillus subtilis. In this study, to secrete methyl parathion hydrolase (MPH) into the growth medium,(More)
