Edible and medicinal mushrooms have usually been considered as a sustainable source of unique bioactive metabolites, which are valued as promising provisions for human health. Antrodia cinnamomea is a unique edible and medicinal fungus widespread in Taiwan, which has attracted much attention in recent years for its high value in both scientific research and commercial applications owing to its potent therapeutic effects, especially for its hepatic protection and anticancer activity. Due to the scarcity of the fruiting bodies, the cultivation of A.

In the present study, the relationships among fermentation conditions (in terms of pH and shaking/agitation speed), mycelial morphology and the production of Monascus yellow pigments were investigated in both shake-flask and scale-up bioreactor experiments. In the shake-flask fermentation, the highest yield of the Monascus yellow pigments was obtained at pH 5.

First, the established kinetic models and kinetic parameters showed that the cell growth, Monacolin K formation and glycerol consumption in SSF were more rapid than those in SmF. Secondly, the comparison of fatty acid composition of mycelial cells indicated a better fluidity and permeability of the cell membrane in SSF than that of SmF, which was also consistent with the difference in the ratio of extracellular/intracellular Monacolin K between the two systems.

However, almost all studies in this field have focused on the biological activity of Antrodin C and relatively rare information has been reported regarding the biosynthetic process of Antrodin C. In this study, the strategies of pH-shift and glucose feeding for enhanced production of Antrodin C in submerged fermentation of A.

A comparative study showed that MK production in SSF was about 5.5 times higher than that of submerged fermentation when 26 % of glycerol was used, which may be due to the formation of glycerol concentration gradients in the inert carrier and less catabolite repression in SSF.

Methods: Anti-CBL antibody, was raised by immunization against CBL-BSA in rabbits. CBL-OVA was coated by physical adsorption onto the microtitre plate, CBL or sample with CBL as a competitor.
Objective: In order to survey the natural occurrence of citrinin in Monascus products.
Methods: A total of 114 samples with either solid or liquid phases, collected from markets or delivered by the food production factories were analyzed by HPLC for citrinin.
Results: The results revealed that 68 (59.
