| Abstract | The objective of this study was to select highly effective plant growth-promoting bacterial endophytes (PGPE) from sugarcane. The PGPE were isolated from healthy roots of sugarcane and were evaluated for their plant growth-promoting (PGP) traits including phosphate solubilization, siderophore production, indole-3-acetic acid (IAA) production and antimicrobial activities. Based on 16S rRNA gene sequencing, 99 isolates of endophytic actinomycetes belong to genera Actinomadura, Microbispora, Micromonospora and Streptomyces and 52 isolates of endophytic bacteria belong to genera Acinetobacter, Bacillus, Enterobacter, Kluyvera, Lysinibacillus, Micrococcus, Paenibacillus, Pantoae and Staphylococcus. On the basis of PGP-traits, Enterobacter sp. EN-16, Pantoae sp. EN-29, Microbispora sp. GKU 827 and Streptomyces sp. GKU 833 were selected to determine for effects of plant growth on maize plants in pot experiment. The significantly increased root and shoot biomasses were observed in maize plants with co-inoculation of Microbispora sp. GKU827, Enterobacter sp. EN-16 and Pantoae sp. EN-29. This finding revealed that co-inoculation of good candidates from both bacteria and actinomycetes gave better enhancement of plant growth than individual inoculated and un-inoculated treatments. |
