Abstract

Abstract:

The mycelial pellet is a kind of microorganism grain formed naturally under certain culture conditions. And it has the characteristics of not only strong metabolites ability and adsorption capacity of pollutants, but also good biological activity, fast sedimentation rate and easy solid-liquid separation. Recently, it has become a research hotspot in biomedical engineering and environmental protection fields at home and abroad. The characteristics and formation mechanism of mycelial pellets, optimization of culturing conditions were reviewed. The applications of mycelial pellets, including in industrial fermentation production, water pollution control and economic microalgae recovery etc., were introduced in detail. Then, the problems that existed in the current research were analyzed. Furthermore, this paper concluded the research directions and development trends of research on mycelial pellets.

Key words: mycelial pellet, formation mechanism, biomass carrier, fermentation, recovery
