“…In this study, the higher the CMY values for the four equations, the higher the μ m values so determined. A similar observation has been reported in the literature with the application of MGM when employing acid pretreatment …”

“…The change in the amounts of cellulose, hemicellulose and lignin as a result of sulphuric acid pretreatment is shown in Figure . As sulphuric acid concentration increases, cellulose and hemicellulose degradation increases, but acid pretreatments were less effective in lignin degradation; the results of this study were consistent with this finding. The highest cellulose, hemicellulose and lignin degradation rates as a result of sulphuric acid pretreatment were 27.5% ± 1.4%, 35.9% ± 2.9% and 14.5% ± 1.5%, respectively.…”

“…This phenomenon may be attributed to the weakening of the bacteria's resistance to SO 4 2− ions deposited in the reactor when the sulphuric acid concentration applied is more than 3% v/v. Sarto et al reported the optimal amount of sulphuric acid applied to organic waste was 5.0% v/v. Syaichurrozi et al reported optimal biogas yield for Salvinia molesta with a sulphuric acid concentration of 4.0% v/v.…”

“…Syaichurrozi et al reported the organic sample yield increased from 22.72 to 24.14 mL/g VS as a result of the acid pretreatment. 5% v/v sulphuric acid has been used on the water hyacinth plant by Sarto et al who demonstrated an associated increase in total biogas of 131.45% compared to untreated product. The application of pretreatments leads to different results depending on the type of substrate.…”

In this study, anaerobic co-digestion of apple pulp (AP) with high carbon content and chicken manure (CM) with high nitrogen content was evaluated with regard to sulphuric acid pretreatment conditions in the concentration range of 1%-6% v/v. The best mixing ratio of CM:AP was determined as 3:1 w/w under untreated conditions for which the methane yield was 255.88 ± 11.55 mL/g VS (volatile solid). Sulphuric acid pretreatments were applied to this mixture ratio.The highest methane yield after pretreatment was 466.01 ± 10.85 mL/g VS in the reactor, where the sulphuric acid pretreatment concentration was 3.0% v/v. Control of acid pretreatment results were achieved by analysis of lignocellulosic degradation and increase in soluble chemical oxygen demand. The highest cellulose, hemicellulose and lignin degradation after pretreatment were 27.5% ± 1.4%, 35.9% ± 2.9% and 14% ± 1.5% w/w, respectively. The cumulative methane yields (CMY) were analysed by the modified logistic model, modified Bertalanffy model (MBM), modified Gompertz model (MGM) and modified Holling model (MHM). The MBM and MGM were found to fit the experimental data better than other models. The MHM has not previously been applied to CMY. In addition to the kinetic studies, new critical points for CMYs were identified in the logistics model (lm). The importance and critical properties of these points with regard to CMY are introduced. The differences and superior properties of these critical points compared to other modelling methods are discussed.

“…Different cost-effective pretreatment methods have been identified based on different types of lignocellulosic biomass and productivity (Srivastava et al 2015). The effectiveness of these pretreatments depends on the physical structure and chemical composition of the biomass, as well as the pretreatment conditions (Sarto et al 2019). The choosing of a pretreatment method can determine the success in overcoming this complicated structure and the factors that constrain the enzymatic hydrolysis of the lignocellulosic biomass (Sun et al 2016).…”

Effects of acid, alkali, ionic liquid (IL), and microwave-alkali pretreatments on cellulosic water hyacinth (WH) were investigated based on the total reducing sugars (TRS) and ethanol production. For the first time, IL pretreatment with (1-Ethyl-3-methylimidazolium acetate ([EMIM][Ac]) was used for WH, and the efficiency was compared with the other methods. Cellulase and Saccharomyces cerevisiae were fermented together for 72 h. Based on the results, all pretreatment methods effectively increased the sugar content as well as the ethanol yield. Untreated WH had 25 ± 1.5 mg/g of TRS, which was increased to 157 ± 8.2 mg/g, 95 ± 3.1 mg/g, 51 ± 4.2 mg/g, and 45 ± 2.6 mg/g via alkali, microwave-alkali, acid, and IL pretreatments, respectively. The highest TRS level of 402 mg/g was obtained in 24 h and 6.2 ± 0.4 g/L of ethanol in 48 h of fermentation with the alkali-treated WH. The ethanol production was followed by other treatment methods of WH in the order of microwave-alkali, acid, and IL. The results indicated that the ethanol production from WH was related to the type of pretreatment as well as the TRS production.
