Anaerobic conversion of biomass upon disintegration in ultrasonic fields of low intensity

Abstract

Disintegration is the destruction of the cell structure to release all its contents. This process facilitates bacteria access to nutrients and it results in a substrate decomposition rate increase. We can use thermal (the brief heating below one hundred degrees temperature at normal pressure or higher one hundred degrees temperature at enhanceable pressure) and chemical (enzymes and catalysts addition, which can positively influence the process speed), biochemical and physical-mechanical methods (the sonication). © 2014 WIT Press.
