the chitinase producing ability of pseudomonas fluorescens strains viz., pf1, pb2 and fp7 was evaluated in a culture medium with and without a chitin source. the addition of 1% (v/v) chitin in culture medium significantly increased the bacterial population and chitinase activity. among three strains tested, fp7 responded well to the addition of chitin by producing 31.2% increased chitinase in c...

The utilization of native yeast strains associated with a distinct terroir for autochthonous grape types represents novel trend in winemaking, contributing to the production unique wines regional character. Hence, this study aimed isolate H. uvarum from surface various fruits and characterize its fermentation capability Prokupac must. Out 31 yeasts, 8 isolates were identified as uvarum. able gr...

the aims of this study were to compare the promoter sequence of the mannose-binding lectin (cmbl) gene in iranian native and commercial chicken strains; as well as to compare the cmbl gene expression in crossbred and inbred chickens. in total 79 native (western azerbaijan native fowls, wanf) and 49 commercial (arian commercial strain, acs) birds were reared as parents under same management prac...

Many species or strains of the genus Pseudomonas have been characterized as plant growth promoting rhizobacteria (PGPR). We used a combination of phenotypic and genotypic techniques to analyze the community of fluorescent Pseudomonas strains in the rhizosphere of commercially grown Mentha piperita (peppermint). Biochemical techniques, Amplified rDNA Restriction Analysis (ARDRA), and 16S rRNA ge...

in this research, bacillus strains efficiency were tested to control root knot nematode, meloidogyne javanica .one hundred and fifty strains were isolated from tomato rhizosphere. antagonistic activity of strains on m. javanica was checked in vitro assay. nematicidal ability of bacterial suspension of 1 × 108 cfu/ml was investigated on nematode egg and larvae with three replication using random...
