Effects of oxygen-radical pretreatment on the viscosity of CMC solutions and CMC hydrolysis. a Apparent viscosity of the CMC suspensions pretreated with oxygen gas and plasma 2.0% (w/v) was measured using a rheometer at a shear rate of 200 s−1. Values were normalized based on the effects of temperature and shearing on viscosity. b Pretreatment time-dependent production of reducing sugars released from oxygen-gas- (circles) or oxygen-radical-pretreated (triangles) CMC by enzymatic hydrolysis using culture supernatant was assayed using the DNS method. Error bars represent the mean ± standard error of the mean of three independent experiments
