Various types of functional biopolmers were produced from many kinds of edible mushrooms by submerged cultures. Amongst 23 mushrooms examined, Paecilomyces japonica showed the highest biopolyemr production (about 30 g/l).The influence of pellet morphology of P. japonica on fermentation broth rheology and exo-biopolymer production was investigated. Compact pellets with least hairiness and roughness, which improved the flow characteristics of the fermentation broth were observed at 40 g/l of sucrose and hence regarded as the most productive morphological form. At mild agitation, high aeration and optimum substrate concentration, pellets were the most predominant morphological form compared to free mycelia. Compact pellets with least hairiness and roughness, which improved the flow characteristics of the fermentation broth were observed at 40 g/l of sucrose and hence regarded as the most productive morphological form. The molecular mass and its distribution of the biopolymers was analyzed by MALS. Basic funtionalities of several biopolymers was also investigated. |
