“…This allowed obtaining a net energy in the amount of 1.309 and 1.279 MJ/kg VS, respectively. Głąb and co-workers [40] show that from one cubic diameter of methane an energy equal 0.036 MJ can be obtained [40]. Results obtained in the present work shown that for the best variant of treatment of rye straw with sulfuric acid net energy of 11.105 MJ/kg VS can be obtained.…”

“…In our research, we received 0.04 L of ethanol from each kilogram of rye straw (VS), so the net energy gain was 0.674 MJ/kg VS. According to Głąb and co-workers [40] the calorific value of ethanol is 21.26 MJ per L [40].…”

“…The use of waste biomass, e.g., straw, reduces the cost of obtaining raw material and reduces energy demand through properly selected pre-treatment. The energy needed is only used for the fermentation and rectification of ethanol [40,41]. In our research, we received 0.04 L of ethanol from each kilogram of rye straw (VS), so the net energy gain was 0.674 MJ/kg VS.…”

The study describes sulfuric acid pretreatment of straw from Secale cereale L. (rye straw) to evaluate the effect of acid concentration and treatment time on the efficiency of biofuel production. The highest ethanol yield occurred after the enzyme treatment at a dose of 15 filter paper unit (FPU) per gram of rye straw (subjected to chemical hydrolysis with 2% sulfuric acid (SA) at 121 °C for 1 h) during 120 h. Anaerobic digestion of rye straw treated with 10% SA at 121 °C during 1 h allowed to obtain 347.42 L methane/kg volatile solids (VS). Most hydrogen was released during dark fermentation of rye straw after pretreatment of 2% SA, 121 °C, 1 h and 1% SA, 121 °C, 2 h—131.99 and 134.71 L hydrogen/kg VS, respectively. If the rye straw produced in the European Union were processed into methane, hydrogen, ethanol, the annual electricity production in 2018 could reach 9.87 TWh (terawatt-hours), 1.16 TWh, and 0.60 TWh, respectively.

“…In the above study, likewise in research of Głąb et al [31], the substrate pretreatment involved the acidic pre-hydrolysis. In turn, Cao et al [32] compared various methods for sorghum biomass pre-hydrolysis and achieved the best result upon the coupled use of a diluted sodium hydroxide solution and hot hydrogen peroxide.…”

Bioconversion of Sweet Sorghum Residues by Trichoderma citrinoviride C1 Enzymes Cocktail for Effective Bioethanol Production

Improved cost-effective bioethanol production using inexpensive enzymes preparation was investigated. Three types of waste lignocellulosic materials were converted—for the production of enzyme preparation, a mixture of sugar beet pulp and wheat bran, while the source of sugars in hydrolysates was sweet sorghum biomass. A novel enzyme cocktail of Trichoderma citrinoviride C1 is presented. The one-step ultrafiltration process of crude enzyme extract resulted in a threefold increase of cellulolytic and xylanolytic activities. The effectiveness of enzyme preparation, compared to Cellic® CTec2, was tested in an optimized enzymatic hydrolysis process. Depending on the test conditions, hydrolysates with different glucose concentrations were obtained—from 6.3 g L−1 to 14.6 g L−1 (representing from 90% to 79% of the CTec2 enzyme yield, respectively). Furthermore, ethanol production by Saccharomyces cerevisiae SIHA Active Yeast 6 strain DF 639 in optimal conditions reached about 120 mL kg d.m.−1 (75% compared with the CTec2 process). The achieved yields suggested that the produced enzyme cocktail C1 could be potentially used to reduce the cost of bioethanol production from sweet sorghum biomass.
