“…Drenching of > 50 μg/ml EtOAc extract to the culture dishes showed significantly lower disease severity of bakanae, indicating the induction of systemic resistance by chemical compounds. It is well known that Bacillus species produce many kinds of small peptides and lipopeptides, such as fengycin, iturin and surfactin, having antifungal and ISR activity ( Bais et al, 2004 ; Crane et al, 2013 ; Dimkic et al, 2013 ; Ongena et al, 2009 ; Park et al, 2006 ).…”

In our previous study, we reported that a novel endophytic bacterium Bacillus oryzicola YC7007 has suppressed bacterial diseases of rice via induced systemic resistance and antibiotic production. This endophytic strain, B. oryzicola YC7007 was used as a biological control agent against bakanae disease of rice caused by Fusarium fujikuroi, and its mechanism of interaction with the pathogen and the rice was further elucidated. Root drenching with B. oryzicola YC7007 suspension reduced the disease severity of bakanae significantly when compared with the untreated controls. The treatments of B. oryzicola YC7007 suspension (2.0 × 107 cfu/ml) to the rice rhizosphere reduced bakanae severity by 46–78% in pots and nursery box tests containing autoclaved and non-autoclaved soils. Moreover, in the detached rice leaves bioassay, the development of necrotic lesion and mycelial expansion of F. fujikuroi were inhibited significantly by spraying the culture filtrate of B. oryzicola YC7007. Drenching of ethyl acetate extracts of the culture filtrate to the rhizosphere of rice seedlings also reduced the bakanae disease severity in the plant culture dish tests. With the root drenching of B. oryzicola YC7007 suspension, the accumulation of hydrogen peroxide was observed at an early stage of rice seedlings, and a hormonal defense was elicited with and without pathogen inoculation. Our results showed that the strain B. oryzicola YC7007 had a good biocontrol activity against the bakanae disease of rice by direct inhibition, and was also capable of inducing systemic resistance against the pathogen via primed induction of the jasmonic acid pathway.

“…subtilis, an ubiquitous bacterium commonly found in various ecological niches that does not have any history of pathogenicity from contact in the environment, was shown to be a potential biocontrol agent of harmful phyto-pathogenic fungi and bacteria, mosquitoes and nematodes (Ongena et al, 2010). Table 2 enumerates a wide array of B. subtilis derived biopesticides along with their chemical nature, producing strain and antagonist strain.…”

“…Por otro lado, el género Bacillus sp agrupa bacterias que se destaca por formar endoesporas que permiten su . supervivencia en diferente condiciones medioambientales adversas; poseen además la ventaja de presentar múltiples mecanismos antagónicos frente otros organismos especialmente hongos patógenos de plantas (Ongena, Henry & Thonart, 2009;Ramírez, Lozano, Méndez, Rojas & Torres, 2017;Tejera-Hernández, Rojas-Badía & Heydrich-Pérez, 2011).…”

“…Varios reportes anteriores han mencionado que especies de Bacillus, incluidos B. subtillus y B. pumilus, reducen la incidencia y severidad de patógenos en plantas, y actúan como inductores de resistencia (Araújo Almeida et al, 2007;Mertz, Henning and Zimmer, et al, 2009;Ongena et al, 2009;Pérez-García, Romero & Vicente, 2011;Xu, Jeffries, Pautasso & Jeger, 2011); además, promueven el crecimiento en consecuencia del aumento de la fijación de nitrógeno, solubilización de nutrientes, síntesis de fitohormonas y también de forma indirecta por inhibición del crecimiento de fitopatógenos, por eso son consideradas bacterias promotoras del crecimiento vegetal (PGPB) (Manjula & Podile, 2005;Pérez-García et al, 2011;Souza, Ambrosini & Passaglia, 2015;Xu et al, 2011).…”

Las especies de Typha sp son utilizadas en tratamientos de fitorremediación de manera exitosa. CEMIT - DGICT - UNA ha propuesto como alternativa a problemática del lago Ypacaraí, el uso de esta planta para su recuperación. El objetivo de este trabajo fue utilizar especies de Bacillus sp. para estimular la germinación de las semillas y aumentar el vigor y crecimiento de las plántulas de Thypa dominguensis. Para ello, se aislaron Bacillus sp. de semillas de Thypa dominguensis y se seleccionaron dos aislados que fueron utilizados para el tratamiento de las mismas mediante la inoculación con suspensiones bacterianas; las semillas fueron sembradas y acondicionadas en casa de vegetación por 30 días, al cabo de los cuales se procedió con las evaluaciones y se observó que las plantas tratadas con laUniversidad Nacional de Asunción. Dirección General de Investigaciones Científicas y Tecnológicas. San Lorenzo, Paraguays bacterias presentaron mejor porcentual de germinación, mayor longitud y biomasa con relación al testigo, demostrando que el tratamiento fue eficiente en la estimulación del crecimiento y aumento de la biomasa.
