Alternatively, first step of autohydrolysis (S0 = 4.22) allowed a high oligosaccharides recovery (68%) and subsequent lime pretreatment attained a 57% of delignification and 99% of glucan to glucose conversion.
To achieve this and accordingly improve subsequent hydrolysis, pretreatment techniques are essential [ 6, 14, 16, 32].
Both the microbial and metabolic consortium shifted extensively towards enhanced biodegradation subsequent to pretreatment, providing insight for the enhanced methane yield.
However, a significant decrease (P < 0.05) was noticed for all the studied serum parameters subsequent to pretreatment with HaE for 14 days, as compared to the corresponding DMBA group (Tables 1, 2, and 3).
ICSE also has positive impacts on the efficiency of subsequent chemical pretreatments involved with organic solvent, acid, and alkali (Liu et al. 2014b).
Subsequent to this pretreatment, 91.71% cellulose, 39.29% hemicellulose, and 18.30% lignin were recovered.
However, subsequent to NH3-H2O2 pretreandent and washing the solid fraction exhibited a 19.54% increase in cellulosic composition and the percentage of hemicellulose, lignin, and ash decreased slightly compared to raw material prior to pretreatment (Table 1).
During subsequent chlorination, ozonation pretreatment reduced the formation of haloacetonitriles from EOM, but increased the yields of trihalomethanes, dihaloacetic acid and trichloronitromethane from both EOM and IOM.
The research results showed that the dyed MAO film achieved the optimal color saturation (L* a* b*) = (53.55, 1.17, − 29.16) when the specimen was immersed in a blue dye to undergo a dyeing process with an applied anodic current of 1 A subsequent to the pretreatment at an applied cathodic voltage of 30 V.
