- Recently all the nations are competitively focusing on developing biorefinery technologies.
Biorefinery is defined as a bioprocess to produce high-valued industrial chemicals and energy
using natural biomasses which are present enormously in nature. Cassava is a good alternative
biomass source which could be used to produce various biorefinery products. The roots of
cassava are mainly composed of 20∼25% starches and contain plenty of valuable nutrients
such as vitamin C and calcium. Recently, it has been reported that a newly-developed super
cassavas is being tested to be used as a carbon and energy source in biorefinery industries. Our
research team intended to develop an economic bioprocess for mass production of
exopolysaccharides(EPS) using cassava as a carbon source in liquid mycelial fermentations of
Schizophyllum commune [1]. This product has the potent capability of maintaining high
moisturized conditions on epidermal tissue, and also having positive effects on the restoration
of epidermal tissue. First of all, medium optimization process was carried out in order to find
an optimal composition of the production medium containing the cassava biomass.
Approximately 2~3 fold increase in EPS productivity was observed in the shake flask cultures
performed with the optimized production medium [2]. For the purpose of enhancing the EPS
production, intensive strain improvement program was also carried out by obtaining large
amounts of protoplasts for the isolation of single colonies. Mass screening for high-yielding
producers was possible through the formation of the protoplasts of S. commune because high
concentration of protoplasts(5x106 protoplasts/ml) could be recovered with efficient cell wall
disrupting enzymes. Notably, the protoplast regeneration rate was as high as 98% when RPA
medium containing 1.2M sorbitol was used as a regeneration medium.
