Two novel transposon delivery vectors based on mariner transposon for random mutagenesis of Bacillus thuringiensis.
Two new mariner transposon delivery vector systems, pMarA333 and pMarB333, had been constructed to randomly mutagenize Bacillus thuringiensis in vivo. The results showed that both systems could randomly insert into the genome of B. thuringiensis YBT881 (CCAM 020673). These systems could have potential for further construction of mutant libraries of B. thuringiensis and other Bacillus strains.

متن کاملTransposon mutagenesis in Halomonas eurihalina.
We have established a transposon mutagenesis procedure for the moderate halophile Halomonas eurihalina, a bacteria that produces an exopolysaccharide (EPS) of considerable biotechnological interest. We used suicide plasmids pUT and pSUP102 to introduce the transposons mini-Tn5 and Tn1732 into H. eurihalina via Escherichia coli mediated conjugation. Southern hybridization analysis demonstrated t...
متن کاملImproving the functional expression of a Bacillus licheniformis laccase by random and site-directed mutagenesis
BACKGROUND Laccases have huge potential for biotechnological applications due to their broad substrate spectrum and wide range of reactions they are able to catalyze. These include, for example, the formation and degradation of dimers, oligomers, polymers, and ring cleavage as well as oxidation of aromatic compounds. Potential applications of laccases include detoxification of industrial efflue...
متن کاملMutagenesis of Bacillus Licheniformis through Ethyl Methanesulfonate for Alpha Amylase Production
The present study is concerned with the improvement of Bacillus licheniformis strain GCB30 for alpha amylase production in 250 ml Erlenmeyer flasks. Chemical mutation using ethyl methanesulfonate (EMS 50-300 μ/ml) was undertaken for 10-60 min. Twenty eight isolates were selected on the basis of clear zones of starch hydrolysis. Only one isolate designated as B. licheniformis EMS-200 gave 102.78...
