Based on the premise that plant biomass can be efficiently degraded by mixed microbial cultures and/or enzymes, we here applied a targeted metagenomics-based approach to explore the metabolic potential of two forest soil-derived lignocellulolytic microbial consortia, denoted RWS and TWS (bred on wheat straw). Using the metagenomes of three selected batches of two experimental systems, about 1.2...

A bacterial strain, DC-186(T), isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15-36 degrees C and pH 5.5-8.0. Strain DC-186(T) was positive in tests for catalase, oxidase and beta-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C(...

Heparinase from different sources can eliminate heparin or/and heparan sulfate into various low-molecular weight heparins with different characteristics. Porcine intestinal mucosa heparin was degraded into a series of oligosaccharides by a novel heparinase from the species Sphingobacterium. Disaccharide components from the digests were separated and purified by ultrafiltration and HPLC. Five ma...

Abstract Background Root-knot nematodes ( Meloidogyne spp.) are the most destructive agricultural pests, which parasitize thousands of different plant species in world. Using antagonistic bacteria can be a potential alternative to hazardous chemical nematicides. This study was conducted evaluate biocontrol activities isolated from vermicompost and earthworm against M. javanica infected tomato p...

Abstract Background Plant growth-promoting bacteria (PGPB) can be used as a safe and sustainable agricultural measure to increase plant yield. In this study, cultivable rhizospheric, endophytic, epiphytic associated with canola were isolated on nutrient agar medium. The SDS-PAGE method was for grouping the bacterial strains. Bacterial strains more than 80% similarity in their protein patterns p...

Abstract Industrial aquaculture has proliferated due to increased world demand for fish and seafood. Aerobic bacterial biofilters typically perform the nitrogen abatement of wastewater. Recirculation systems (RAS) require nitrifying microorganisms developed in biofilter. Despite advantages these biofilters, there are disadvantages, such as time needed mature, decrease oxygen concentration, accu...

Key agreement protocol is of fundamental importance in providing data con dentiality and integrity between two or more parties over an insecure network. In 2004, Popescu [14] proposed an authenticated key agreement protocol in which its security is claimed. However, Yoon and Yoo [19] discovered its vulnerabilities two years later and proposed an improved variant of it. In this paper, we highlig...
