Regulatory mechanism underlying mycelium aggregation during filamentous fungi submerged fermentation / 生物工程学报

ABSTRACT

Filamentous fungi are one of the platforms for producing fermented products. The specific characteristic of their submerged fermentation is the aggregation of mycelia that is affected by environmental conditions, leading to significantly different rheology for fermentation broth. Such a rheological change not only affects the transfer of mass, heat and momentum, but also the biosynthesis of target products and the efficiency of their production. In this article, strategies for morphological regulation of filamentous fungi are reviewed, and the impact of calcium signal transduction and chitin biosynthesis on apical growth of hyphae and branching of mycelia for their aggregation are further commented.
