“…Este resultado comprova o potencial de promoção de crescimento de plantas por Bacillus sp. já encontrado em vários estudos com diferentes culturas (Araujo & Guerreiro, 2010;Figueiredo et al, 2010;Araujo, 2008;Coelho et al, 2007;Malik et al, 1997).…”

Objetivou-se selecionar e caracterizar bactérias do gênero Bacillus em rizosfera de Brachiaria brizantha como promotoras de crescimento de plantas e correlacionar os diferentes critérios de seleção das bactérias utilizados em laboratório e casa-de-vegetação. Após coleta de amostras de plantas em três municípios da região oeste de São Paulo, foram realizados o isolamento de bactérias da rizosfera e posterior caracterização fenotípica quanto ao potencial de colonização de raízes de braquiária, antagonismo a fungos fitopatogênicos, produção de auxinas, fosfatases e proteases, além da caracterização genotípica utilizando a técnica de PCR-RAPD. Como avaliação final dos isolados bacterianos foi realizado experimento em casa-de-vegetação com inoculação de sementes e cultivo de Braquiaria brizantha com efetivação de três cortes, durante 180 dias. O experimento foi distribuído em delineamento inteiramente casualizado com quatro repetições. Dos 45 isolados de Bacillus sp. avaliados, sete foram competentes para colonização radicular e três (1A, 2B e 6A) foram capazes de promover o crescimento de Brachiaria brizantha, na média de três cortes efetuados na cultura. A avaliação da produção de auxinas e fosfatases foi relevante no protocolo de seleção dos isolados de Bacillus sp. como promotores de crescimento de plantas. A produção de proteases foi detectada em todos os isolados avaliados, mas não houve correlação desta característica com o crescimento das plantas.

“…Entre os gêneros mais estudados, destacam-se: Bacillus, Pseudomonas, Azospirillum e Rhizobium. Os efeitos desses microrganismos sobre o desenvolvimento das plantas são amplos e incluem os efeitos benéficos na germinação de sementes, emergência de plântulas e crescimento das plantas (Figueiredo et al, 2010).…”

“…In the rhizosphere the synergism between various bacterial genera such as Bacillus, Pseudomonas and Rhizobium has been demonstrated to promote plant growth and development. Compared to single inoculation, co-inoculation improved the absorption of nitrogen, phosphorus and mineral nutrients by plants (Figueiredo et al, 2010;. A significant increase in root and shoot biomass was observed in chickpea plants when co-inoculated with Mesorhizobium and Pseudomonas (Sindhu et al, 2002a, b).…”

“…Plant growth-promoting bacteria (PGPB) are beneficial microorganisms inhabiting the rhizosphere (FIGUEIREDO et al, 2011). They stimulate plant growth through by acting as biofertilizers and bio-stimulants, increasing the ability of the plant to resist stressful situations (GLICK, 2014;HUANG et al, 2014).…”

Plant growth-promoting bacteria (PGPB) comprise of soil microorganisms that cause positive effects on plant growth. The hypothesis according to which the inoculation of lima bean with PGPB Bacillus stimulates vegetative growth, which may result in a higher plant productivity, was tested. Thus, this study aimed to evaluate the effects of inoculation of two varieties of lima bean (branca and boca de moça) with Bacillus sp., UFPEDA 472 strain, based on plant growth responses. The experiment was conducted in a greenhouse using a completely randomized design. Three treatments were applied separately to each lima bean variety: the first used inoculation with Bacillus, one was submitted to nitrogen supplementation, and one was the absolute control (non-inoculated plants). The following variables were evaluated: absolute and relative growth rate, root length, stem diameter, fresh and dry mass of shoots and roots, shoot:root ratio and total chlorophyll. The results showed that lima bean displayed better growth responses when inoculated with Bacillus sp. UFPEDA 472 in relation to the treatment with nitrogen and/or non-inoculated plants. When inoculated with PGPB Bacillus, the lima bean var. branca was superior to boca de moça in terms of root length and root dry mass. The lima bean var. boca de moça inoculated with Bacillus sp. UFPEDA 472 was superior to branca in terms of absolute growth rate, stem diameter, fresh and dry mass of shoot, shoot:root ratio and total chlorophyll. In general, the lima bean var. boca de moça inoculated with Bacillus shows a better growth performance. Our results suggest that growth responses of lima bean varieties branca and boca de moça are related with a positive interaction with the PGPB Bacillus.
