Temperature-responsive regulation of the fermentation of hypocrellin A by Shiraia bambusicola (GDMCC 60438).

ABSTRACT:

Background

Hypocrellin A (HA) is a perylene quinone pigment with high medicinal value that is produced by Shiraia bambusicola Henn. (S. bambusicola) and Hypocrella bambusae (Berk. & Broome) Sacc. (Ascomycetes) with great potential in clinical photodynamic therapy. Submerged cultivation of S. bambusicola is a popular technique for HA production. However, there is not much research on how temperature changes lead to differential yields of HA production.

Results

The temperature regulation of submerged fermentation is an efficient approach to promote HA productivity. After a 32 °C fermentation, the HA content in the mycelia S. bambusicola (GDMCC 60438) was increased by more than three- and fivefold when compared to that at 28 °C and 26 °C, respectively.
