This study was conducted to compare different liquid culture media for Paenibacillus larvae growth in order to find the best one to be used in studies on activity of antimicrobial substances, such as essential oils. P. larvae presented poor growth in usual broths such as Mueller-Hinton, commonly employed in antimicrobial activity assays. Growth in liquid media was evaluated using Paenibacillus ...
Antibiotic resistance is ancient and widespread in environmental bacteria. These are therefore reservoirs of resistance elements and reflective of the natural history of antibiotics and resistance. In a previous study, we discovered that multi-drug resistance is common in bacteria isolated from Lechuguilla Cave, an underground ecosystem that has been isolated from the surface for over 4 Myr. He...
زانتان پلی ساکارید مهم تجاری است که توسط xanthomonas campestris تولید می شود و به دلیل ویسکوزیته ی بالا در صنایع دارویی ، غذایی و ازدیاد برداشت نفت کاربرد دارد. زانتان پلی مری خطی از گلوکز با پیوند ? (1?4) می باشد که زنجیره جانبی باردار منفی به آن متصل شده است. تجزیه ی زانتان نیز مانند تولید آن می تواند کاربردهای عمده ای داشته باشد. دو دسته آنزیم تخریب کننده ی زانتان وجود دارد. گروه اول شامل هی...
In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...
A novel inulin-degrading bacterium was isolated from a soil sample collected on Jerusalem artichoke roots. It is a Gram-positive, aerobic, motile and central endospore-forming straight rod, and exhibits phenotypic properties being consistent with its classification in the genus Paenibacillus. The predominant cellular fatty acids were anteiso-C15:0, C16:0 and anteiso-C17:0. This strain represent...
Paenibacillus sp. strain JDR-2, an aggressively xylanolytic bacterium isolated from sweetgum (Liquidambar styraciflua) wood, is able to efficiently depolymerize, assimilate and metabolize 4-O-methylglucuronoxylan, the predominant structural component of hardwood hemicelluloses. A basis for this capability was first supported by the identification of genes and characterization of encoded enzymes...
Various bacterial strains (e.g., strains belonging to the genera Bacillus, Paenibacillus, Serratia, and Salmonella) exhibit colonial branching patterns during growth on poor semisolid substrates. These patterns reflect the bacterial cooperative self-organization. A central part of the cooperation is the collective formation of a lubricant on top of the agar which enables the bacteria to swim. H...
