Isolation and characterization of endophytic bacteria from Pennisetum purpureum Schumach

Pennisetum purpureum Schumach, commonly called elephant grass, found in tropical and subtropical climates is used as an energy crop well a forage grass. As part of ongoing exploration environmentally friendly agricultural approaches Vietnam, which includes the utilization endophytic species endogenous bacteria fertilizer synthesis, studies were conducted on Elephant grass specimens gathered examined to investigate advantages during growth. Endogenous capable generating IAA identified from Schumach samples collected provinces Hai Duong, Cao Bang, Thai Nguyen. Five these strains chosen for their capacity stimulate plant development fight harmful bacteria. All selected gram-negative motile After 72 hours medium with pH 7, 100 mg/l L-tryptophan, 30°C liquid NA media, study five bacterial (HDR5, HDR9, TNT3, CBR1, CBR2) that produced maximum amounts IAA. HDR5 CBR2 demonstrated ability inhibit plant-pathogenic Xanthomonas strains. The investigation HDR5’s 16S rRNA nucleotide sequence revealed it closely linked genus Enterobacter. suggests use synthesis effective eco-friendly approach.
