A review of applications of cavitation in biochemical engineering/biotechnology
TL;DR: An overview of the applications of the cavitation phenomenon in the specific area of biochemical engineering/biotechnology, discussing the areas of application, the role of cavitation, the observed enhancement and its causes by highlighting some typical examples is provided in this paper.
Journal ArticleDOI
Sonobioreactors: using ultrasound for enhanced microbial productivity
TL;DR: This review focuses on the productivity enhancing effects of ultrasound on live biological systems and the design considerations for sonobioreactors required for ultrasound-enhanced biocatalysis.
Journal ArticleDOI
Extracellular proteins, polysaccharides and enzymes impact on sludge aerobic digestion after ultrasonic pretreatment.
TL;DR: Ultrasonic pretreatment enhances enzymatic activities and promotes the shifts of extracellular proteins, polysaccharides and enzymes from inner layers of sludge flocs to outer layers, i.e., pellet and TB-EPS, to increase the contact and interaction among extraceocytes that were originally embedded in the sludge Flocs, resulting in improved efficiency in aerobic digestion.
Journal ArticleDOI
Inactivation of microorganisms by low-frequency high-power ultrasound: 1. Effect of growth phase and capsule properties of the bacteria.
TL;DR: The results of this study demonstrate that the main reason for bacterial resistance to ultrasonic deactivation is due to the properties of the bacterial capsule.
Journal ArticleDOI
Effects of ultrasonic disintegration on sludge microbial activity and dewaterability.
TL;DR: Analysis results showed that the changes of sludge microbial activity and dewaterability were dependent on sludge disintegration degree during ultrasonic treatment, and a transmutative power function model can be used to describe the process of ultrasonic disintegration.

Ultrasound Stimulates Ethanol Production during the Simultaneous Saccharification and Fermentation of Mixed Waste Office Paper
TL;DR: Intermittent exposure of SSF processes to ultrasonic energy under selected conditions was bacteriostatic and decreased ethanol production but may be useful for the controlling bacterial growth in other processes.
Journal ArticleDOI
Acceleration of cell growth and ester formation by ultrasonic wave irradiation
TL;DR: In this paper, the effects of ultrasonic wave irradiation on cell growth and the formation of ethanol and other volatile components in the fermentation process were investigated, and it was suggested that irradiation accelerates the development of ethanol, mainly by decreasing the dissolved carbon dioxide concentration.
