Tohoku Univ. Technology:High-density culture of mutant filamentous fungi: T12-060
For mass fermentative production of useful substances!
Filamentous fungi have an advantage to produce a wide variety of useful substances in industry. However, it is well-known that hyphal aggregation during the liquid culture often prevents fungi to grow with high density, resulting in low productivity of useful substances. This invention discloses a mutant strain of a filamentous fungi, in which α-1,3-glucan synthase (AGS) gene is deficient, for high productivity of substances. The α-1,3-glucan in the cell wall in AGS deficient mutant (AGΔ) is significantly reduced. The AGΔ cells are dispersed well in a liquid medium and cultured with higher density compared with that of wild type. Such phenotype of AGΔ results in an increasing productivity of useful substances per unit.
