Selection of microrganism for the mobilization of cellulolityc agricultural biomass for energy production
2012
Selection of microorganisms for the mobilization of cellulolytic agricultural biomass for energy production. R. Di Bonito, D. Taschini, C. Viola, Campi otti C.A. Unit Energy Efficiency in Agriculure, ENEA Casaccia, Roma, Italy The production of biofuels as renewable energy source could significantly reduce the negati ve impact of fossil fuels. However, this activity has resulted in increasing land cultivation specifically with carbohydrate-rich crops for energy production, and resulting shortage of crop production for food . The use of residual agricultural biomass as a substrate for biofuels or biogas production could improve the sustainabi lity of the bio-energy production but sti li requ…
Activity of bacterial seed endophytes of landrace durum wheat for control of Fusarium foot rot
2022
Five bacterial endophytic isolates obtained from durum wheat seeds (landrace “Timilia reste nere”) and identified as belonging to Pantoea (isolates A1, F7, F15 and G1) and Paenibacillus (isolate B) genera on the basis of 16S rDNA gene sequences, were assayed in vitro and in vivo for their ability to inhibit Fusarium culmorum growth and the disease (Fusarium foot rot) it causes in durum wheat. All isolates significantly reduced in vitro growth of F. culmorum in comparison with the control. After 120 hours of incubation, isolates B and G1 showed the greatest mycelial growth inhibition, i.e., respectively, 76 and 74%. When durum wheat “Simeto” seeds were treated with bacterial isolates singly …
Hydrolytic enzyme activity of Paenibacillus sp. strain B2 and effects of the antagonistic bacterium on cell integrity of two soil-borne pathogenic fu…
2000
Paenibacillus sp. strain B2, isolated from the mycorrhizosphere of Sorghum bicolor and having an antagonistic activity towards soil-borne fungal pathogens, possessed extracellular cellulolytic, proteolytic, chitinolytic and pectinolytic enzyme activities. The eventual role of these lytic enzymes in cellular interactions between Paenibacillus sp. strain B2 and Phytophthora parasitica and Fusariumoxysporum was investigated by electron microscopy and molecular cytology. Electron microscopic observations showed that the presence of Paenibacillus sp. strain B2 resulted in disorganisation of cell walls and/or cell contents of P. parasitica and F. oxysporum. However, when P. parasitica was treated…
