Phosphate-solubilizing bacteria (PSB) have the ability to solubilize insoluble phosphorus (P) and release soluble P. Extensive research has been performed with respect to PSB isolation from the rhizospheres of various plants, but little is known about the prevalence of PSB in the grapevine rhizosphere. In this study, we aimed to isolate and identify PSB from the grapevine rhizosphere in five vineyards of Northwest China, to characterize their plant-growth-promoting (PGP) traits, evaluate the effect of stress on their phosphate-solubilizing activity (PSA), and test their ability to stimulate the growth of Vitis vinifera L. cv. Cabernet Sauvignon. From the vineyard soils, 66 PSB isolates were screened, and 10 strains with high PSA were identified by 16S rRNA sequencing. Sequence analysis revealed that these 10 strains belonged to 4 genera and 5 species: Bacillus aryabhattai, B. megaterium, Klebsiella variicola, Stenotrophomonas rhizophila, and Enterobacter aerogenes. The selected PSB strains JY17 (B. aryabhattai) and JY22 (B. aryabhattai) were positive for multiple PGP traits, including nitrogen fixation and production of indole acetic acid (IAA), siderophores, 1-aminocyclopropane-1-carboxylate (ACC) deaminase, chitinase, and protease. JY17 and JY22 showed strong PSA under stress conditions of high pH, high salt, and high temperature. Therefore, these two isolates can be used as biofertilizers in saline-alkaline soils. The inoculation with PSB significantly facilitated the growth of V. vinifera cv. Cabernet Sauvignon under greenhouse conditions. Use of these PSB as biofertilizers will increase the available P content in soils, minimize P-fertilizer application, reduce environmental pollution, and promote sustainable agriculture.Additional key words: promote plant growth; inorganic phosphate; stress conditions; saline-alkaline soil; Vitis vinifera L. cv.

RESUMOGossypium hirsutum L. consiste na espécie de algodão mais cultivada em todo o mundo, apresentando importante significância histórica e econômica, principalmente no continente americano. Além das típicas pragas que afetam amplamente o algodoeiro, sabe-se que a planta exibe uma diversa comunidade microbiana simbiótica. Micro-organismos endofíticos são definidos como aqueles que passam parte ou todo o período de vida colonizando assintomaticamente tecidos vegetais e, por vários mecanismos, podem promover o crescimento do hospedeiro e participar de sua proteção frente à patógenos. O objetivo do atual estudo foi o isolamento e avaliação qualitativa de diversas potencialidades biotecnológicas de bactérias endofíticas isoladas de folha de algodão. Nove morfotipos bacterianos foram isolados, com 77,7% exibindo positividade para pelo menos um dos testes de triagem. O mesmo percentual de isolados (77,7%) foi capaz de gerar ácido-indolacético (AIA), 66,6% solubilizaram fosfato e 55,5% cresceram em meio livre de nitrogênio. Dois isolados, AL1 e AL8, geraram exoenzimas extracelularmente e apenas um morfotipo, AL1, foi hábil em inibir o crescimento de uma das cepaspadrão bacterianas empregadas como indicadoras. Os resultados são promissores para a condução de estudos futuros que consolidaram essas possíveis aplicações das bactérias endofíticas de algodão sobre as mais diversas áreas no campo biotecnológico. PALAVRAS-CHAVE: algodão, bactérias endofíticas, bioprospecção.

“…Among the most promising alternatives for fertilizer, stone powder is noted, which provides the use of crushed rocks rich in micronutrients and macronutrients as restorative and renewing sources of the soil, can help reduce highly soluble chemical products such as fertilizers in the NPK form (Beneduzi et al, 2013).…”

A B S T R A C TThe study was conducted in a greenhouse at the Agricultural Research Corporation of Rio Grande do Norte (EMPARN), in order to evaluate the effect of biofertilizers and potassium phosphate rocks, triple superphosphate (TSP) and potassium chloride (KCl), crushed rocks on the chemical properties of the soil and performance of the bacteria Paenibacillus polymyxa in the absorption of macronutrients by the cowpea bean crop. An Ultisol (10 kg per pot) was used with the addition of biofertilizers at levels 40, 70, 100 and 200% of recommendation for TSP and KCl, inoculated or not with bacteria. There was an effect of fertilization on the absorption of macronutrients, being the best results for P and K with TSP + KCL, and N, Ca and Mg for the biofertilizers. In the chemical properties of the soil, the pH was lower in biofertilizers of higher levels, but it was better especially with its addition to P (BPK200). For Ca it was better with TSP + KCl, and Mg with pure rock. The P. polymyxa did not influence in absorption of elements by the plant. The biofertilizers and rocks could satisfy the nutrient needs of the plants by making them potential for sustainable agriculture.Biofertilizantes e performance do Paenibacillus na absorção de macronutrientes pelo feijão caupi e fertilidade do solo R E S U M O O trabalho foi conduzido em casa de vegetação, na Empresa de Pesquisa Agropecuária do Rio Grande do Norte (EMPARN) para avaliar o efeito de biofertilizantes de rochas potássica e fosfatadas, superfosfato triplo (SFT) e cloreto de potássio (KCl), rochas moídas nas propriedades químicas do solo e no desempenho da bactéria Paenibacillus polymyxa na absorção de macronutrientes na cultura do feijão caupi. Utilizaram-se 10 kg de um Argissolo Amarelo Distrófico por vaso com adição dos biofertilizantes nos níveis 40, 70, 100 e 200% da recomendação para SFT e KCl, inoculados ou não com a bactéria. Houve efeito da fertilização na absorção dos macronutrientes sendo os melhores resultados para P e K com SFT+KCL, e N, Ca e Mg para os biofertilizantes. Nas propriedades químicas do solo o pH foi mais reduzido nos biofertilizantes de maiores níveis porém melhorando com sua adição especialmente para P (BPK200). Para Ca foi melhor com o SFT+KCl, e para Mg rocha pura. O P. polymyxa não influenciou na absorção dos elementos na planta. Os biofertilizantes e as rochas supriram a necessidade de nutrientes das plantas revelando-se como potencial para uma agricultura sustentável.
