“…There are different techniques and strategies used to combine hydrolysis and the fermentation step in one single reactor [ 136 , 137 ]. Separate hydrolysis and fermentation (SHF), where enzymatic hydrolysis is separated from the fermentation step has the ability to perform each step under optimal conditions [ 138 , 139 ].…”

As the need for non-renewable sources such as fossil fuels has increased during the last few decades, the search for sustainable and renewable alternative sources has gained growing interest. Enzymatic hydrolysis in bioethanol production presents an important step, where sugars that are fermented are obtained in the final fermentation process. In the process of enzymatic hydrolysis, more and more new effective enzymes are being researched to ensure a more cost-effective process. There are many different enzyme strategies implemented in hydrolysis protocols, where different lignocellulosic biomass, such as wood feedstocks, different agricultural wastes, and marine algae are being used as substrates for an efficient bioethanol production. This review investigates the very recent enzymatic hydrolysis pathways in bioethanol production from lignocellulosic biomass.

“…A sacarificação e a fermentação são processos que podem ser realizados de forma isolada (hidrólise e fermentação separadas) ou simultaneamente (sacarificação e fermentação simultâneas). Isso torna-se possível pela utilização de processos que envolvam a interação entre a enzima responsável pela hidrólise do substrato e a levedura responsável pela fermentação (SHADBAHR et al, 2018;SZAMBELAN et al, 2018). As técnicas combinadas geram menores custos operacionais e maior rendimento de etanol (AZHAR et al, 2017;SEWSYNKER-SUKAI;KANA, 2018;SOTI et al, 2018), além de permitirem a fermentação dos açúcares à medida que estes são liberados, eliminando os problemas de inibição causados pelo acúmulo de mono-e dissacarídeos (FERNANDES-KLAJN et al, 2018).…”

“…To meet this exorbitant demand there is a necessity to quantify a number of unexplored feedstock in order to meet the concerned capacity production with its advancement. As per the availability of reports some of the successfully explored potential starchy sources like wheat 4,5 , corn 6,7 , barley 8,9 , sweet potato 10 , maize 11 , rice 12 , potato 13 , cassava 14 and waste food grains 15 already has gained importance with defined technology and resources. Though these food crops have a huge demand in agriculture, there are all possibilities that they may pose threats of food vs. fuel conflicts 16 .…”

Current technologies for the production of biofuels from various renewable feedstocks have considerably captured vast scientific attention due to the fact that they can be used as an alternative fuels. Bioethanol being one of the most interesting biofuels and due to its positive impact on the environment has been categorised significantly in terms of scientific and technological investments. The aim of this study was to investigate, tubers of Amorphophallus paeoniifolius biomass as a feedstock for bioethanol production. The composition analysis of A.paeoniifolius tubers revealed high carbohydrate content (78.30 ± 0.33%). The feedstock was subjected to physicochemical pretreatment by treating with dilute acid followed by pressure cooking. The pretreatment factors were optimized by CCD using RSM approach. The optimum condition was found to be 1.32%v/v of HCl, 5.83%w/v of Elephant Foot Yam Biomass and 66.84 min of pressure cooking time yielding 45.87 g/L of total sugar. The second order polynomial equation was generated for the saccharification of the biomass and validated with R2 0.89. The fermentation of pretreated biomass in the presence of Saccharomyces cerevisiae MTCC170 yielded 22.12 ± 0.62 g/L of bioethanol at 120 h utilising 92% of initial total sugar. The resultant ethanol yield and productivity was estimated to be 0.51 g/g and 0.30 g/L.h respectively. The Gompertz model equation was applied to experimental data using nonlinear regression with the least square method and the kinetic fermentation parameters such as maximum ethanol concentration (Pm), production rate (rpm) and lag phase (h) were estimated to be Pm =21.90 g/L, rpm =0.57 g/L.h and tL =8.22 h.
