Plant growth promoting rhozobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. Environmental protection and the need to enhance agricultural output have made research in new sustainable technologies necessary. As in most sectors of agriculture, there is increasing demand for organic tomatoes. Therefore, the overall strategy for increasing crop yields, sustaining them at a high level and maintaining proper soil health must include an integrate approach to develop effective and more consistent active plant growyh promoting rhozobacteria (PGPR) inocula,...

Xylan is the major hemicellulosic constituent of hard and soft wood, and is the next most abundant renewable polysaccharide after cellulose.Xylanases and associated debranching enzymes produced by a variety of microorganisms including bacteria, yeast and filamentous fungi, bring about the hydrolysis of hemicelluloses. Xylanolytic enzymes are receiving increasing attention because of their potential application in pulp bleaching and bioconversion of lignocelluloses into feedstocks and fuels.The xylan degrading system includes endo-1,4-xylanases (1,4- -xylan xylanohydrolase; EC 3.2.1.8), which...
