conclusions potato peels were proved to be potentially useful substrates for biosurfactant production by b. pumilus dsvp18. the strain possessed a unique property to reduce surface tension of the media from 72 to 28.7 mn/m. in addition, it showed a stable surface activity over a wide range of temperatures, ph, and saline conditions and had strong antimicrobial activity. this potential of the id...

in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...

american foulbrood (afb) disease is caused by the sporeforming bacterium paenibacillus larvae larvae. traditional diagnosis is based on culture technique is time and laboratory work consuming. in this study with standard strain, pcr was developed by specific primers and pcr products were electrophoresed on 0.8 % agarose gel. the pcr primers were selected on the basis of the 16s rrna gene and am...

The nucleotide sequences of the 3' end of the 16S rDNA and the 16S-23S internal transcribed spacer (ITS) of 40 Bacillaceae species were determined. These included 21 Bacillus, 9 Paenibacillus, 6 Brevibacillus, 2 Geobacillus, 1 Marinibacillus and 1 Virgibacillus species. Comparative sequence analysis of a 220 bp region covering a highly conserved 150 bp sequence located at the 3' end of the 16S ...

To produce chitoorigosaccharides using chitosan, we attempted to construct Paenibacillus fukuinensis chitosanase-displaying yeast cells as a whole-cell biocatalyst through yeast cell-surface engineering. The localization of the chitosanase on the yeast cell surface was confirmed by immunofluorescence labeling of cells. The chitosanase activity of the constructed yeast was investigated by halo a...
