“…4) a nivel in vitro en comparación del control sin inoculación. No se han reportado estudios acerca del efecto de la peletización con Pseudomonas en el desarrollo de la maca, pero estudios similares han reportado que peletizar semillas con inoculantes bacterianos beneficia al desarrollo y crecimiento de las plantas (O'Callaghan 2006; Ryu et al 2006), por otro lado se ha reportado que solo la inoculación de Pseudomonas en semillas de maíz, tomate y maní promueve el crecimiento y estimula la germinación ratificando la aplicación de inoculantes bacterianos en semillas y plantas (Widnyana 2016;Fatemeh 2014;Dey et al 2004). El efecto promotor del crecimiento vegetal se debe a que producen y segregan reguladores del crecimiento como auxinas, giberelinas y citoquininas, mejorando procesos como germinación de semillas, nutrición mineral y desarrollo de raíces (De Souza et al 2015), y a la vez las raíces pueden segregar exudados radiculares como lipopolisacáridos, celulosa, tiamina, aminoácidos, biotina e isoflavonoides, que sirven como nutrientes para las bacterias (Hansen et al 1997).…”

Se produjo biomasa de Pseudomonas sp. LMTK32 a partir de la modificación del medio de cultivo Caldo Extracto de Levadura Manitol (LMC) con el objetivo de incrementar el número de células viables con capacidad de promover la germinación de semillas de maca peletizadas y reducir los costos de producción. En el proceso de optimización, los componentes extracto de levadura y manitol del medio de cultivo LMC fueron reemplazados por fuentes comerciales de sacarosa y glutamato, cuyas concentraciones fueron determinadas en matraces mediante el diseño estadístico de Box-Behnken; además, se determinó el efecto del porcentaje de inóculo en el tiempo de producción de biomasa. Posteriormente se determinó a nivel de biorreactor que 28.57 h-1 fue el valor adecuado del coeficiente volumétrico de transferencia de oxigeno (kLa) a 600 rpm, produciendo 1.28x1011 UFC/mL. En el medio modificado M1, empleando 12.06 g/L-1 de sacarosa, 11.50 g/L-1 de glutamato de sodio y 10.9% de inoculante se obtuvo 15x108 UFC/mL, superando en 52% más el número de células viables con respecto al tratamiento control LMC (7.8x108 UFC/mL). A nivel in vitro, la peletización de semillas de maca con Pseudomonas sp. LMTK32 producidas en biorreactor y en el medio modificado M1 favoreció su germinación. A partir de sustratos orgánicos comerciales se puede producir inoculantes bacterianos eficientes en el desarrollo de cultivos de maca, sin alterar su capacidad de promover el crecimiento vegetal.

“…In previous studies, Paenibacillus species have been used as biological control agents. For example, P. alvei strain K165 has been applied against the cotton black root rot pathogen, Thielaviopsis basicola [25]; P. alvei strain K165, against Verticillium wilt of olive trees [26]; P. polymyxa E681, in sesame seed pelleting for prevention of damping-off diseases and wilt [27] and P. polymyxa cw, against tomato and red pepper powdery mildew [28]. On the other hand, Paenibacillus species are some of the most industrially significant facultative anaerobic bacteria.…”

The chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) is one of the most important insect pests of chestnut. The aim of this study was to isolate and characterize bacteria from D. kuriphilus to obtain new microbial agents for both biological control and other biotechnological applications. D. kuriphilus larvae were collected from chestnut fields located in Bursa and Yalova provinces of Marmara Region of Turkey during May-July 2014. Four bacterial isolates were obtained from D. kuriphilus. According to their morphological, biochemical and molecular properties, these isolates were identified as Staphylococcus saprophyticus (Dk1), Paenibacillus sp. (Dk2), Pseudomonas flourescens (Dk3) and Paenibacillus sp. (Dk4). To the best of our knowledge, this is the first study on the bacterial flora of D. kuriphilus. In our study, the potential of these isolates as a biological control agent against different hazardous pests and other possible biotechnological applications of importance were discussed under the light of literature.

Despite the phytotoxicity of olive-mill solid waste (OMSW) due to its high polyphenols content, OMSW have fertilizer characteristics, which make it a potential source for organic fertilization. Composting of OMSW treatment process was conducted in this study to eliminate the phytotoxicity and solve the environmental impact of this waste. Recycling of OMSW was carried out via composting of six batches of trials using equal proportions of OMSW, cow manure (C) and wheat straw (W). The treatment process was performed at two time intervals (two and five months), after each one, the recipient species (Vicia faba L.) was planted. The results showed the efficiency of composting in reducing OMSW original toxicity after two months than five months. The germination percentage and the plumule and radicle lengths of V. faba showed a significant improvement when the OMSW was composted with C at different proportions before using as soil amendments. Besides, the total biomass was noticeably increased at the high concentration of C-OMSW. Similarly, the total pigments concentration in V. faba was increased by using various composts after two months, where the highest pigment content was observed at 40% W-OMSW treatment.The maximum uptake of potassium and sodium was recorded through the application of W-OMSW compost to soil after two months. Furthermore, the C-OMSW composts showed the highest concentration of nitrogen, calcium, iron and manganese. However, the C-W-OMSW composts recorded the highest concentration of phosphorous, magnesium and copper. Finally, this study developed a low cost treatment that will enable the growers to convert OMSW into a natural nontoxic compost rich with essential nutrients which have positive effects on plants growth.
