| 英文摘要 | - Viticulture is the main agricultural production in the Sao Francisco Valley, Brazil; however, farm soil management systems require large volumes of fertilizer that could contribute to climate change. Therefore, using plant growth -promoting rhizobacteria (PGPR) has been reported to reduce or replace plant input. This study aimed to evaluate the bacteria in the rhizosphere of Vitis vinifera cultivated in the Sao Francisco Valley in Pernambuco, Brazil, and to characterize the mechanisms that promote plant growth. The PGPR with the greatest biotechnological potential was identified using sequencing. The bacteria were isolated from tryptic soy agar (TSA) culture medium inoculated with 100 mu L of a serial dilution. The isolates obtained were characterized phenotypically and tested for their ability to solubilize phosphate, promote biological nitrogen fixation (BNF), and produce indole-3 acetic acid (IAA), biofilms, and antibiotic factors against Xanthomonas campestris pv. viticola. A total of 423 bacteria were obtained, of which 99 presented positive results for at least one of the growth -promotion mechanisms, representing 6.85% for phosphate solubilizers, 0.74% for BNF, 5.7% for IAA synthesizers, 11.27% for biofilm producers, and 4.01% for promoting antibiosis against X. campestris pv. viticola. Isolates 3.19 and 31.14; 3.17 and 17.04; 5.35 and 5.42; and 5.37 identified as Stenotrophomonas, Bacillus, Pseudomonas, and Clostridium, respectively, presented a biotechnological potential for future experiments to promote vine growth. |
