dc.description.abstract | To convert the water hyacinth nature to achieve maximum hydrolysis yield, an experiment was done using sulphuric acid as a catalyst for the pre-treatment process. The enzymatic digestibility of Water Hyacinth (Eichhorniacrassipes) after pre-treatment was determined by measuring the hydrolysis Yield ofthepre-treated material obtained from 24 pre-treatment conditions i.e. Temperatures (108°Cand121°C), sulphuric acid concentrations (0.0,1.0,2.0and3.0%),andresidencetimes(1.0,2.0 And3.0h).When plant material was pre-treated at 121° C for using 3.0% (v/v) sulphuric acid and 1.0h Residence time, highest reducing sugar yield(36.68g/L) from enzymatic hydrolysis was obtained and Enzymatic hydrolysis was 73.4%.The total reducing sugars obtained from pre-treatment and Enzymatic hydrolysis (69.6g/L) were fermented into ethanol using Saccharomycescerevisiae. They
Were converted into 18.25g/L ethanol, which is equivalent to 0.4979g ethanol/g of glucose | en_US |
