“…Sugar and phenolic content are presented in Table 1 . The obtained total sugar (789.35 mg/g DW), reducing sugar (120.32 mg/g DW), and phenolic (76.17 mg EGA/g DW) contents were in line with the results highlighted by Zouhair, et al (2020) [ 34 ] using the same procedures. Based on their results, the total sugar, reducing sugar, and phenolic compounds were 358.28–668.38 mg/g DW, 121.99–267.89 mg/g DW, and 74.37–101.24 mg EGA/g DW, respectively.…”

“…The content of cellulose (19.35%) and hemicellulose (6.75%) in our samples was higher than those reported for argan pulp from nine different localities varying from 8.16% to 16.53% and 3.27% to 5.02% for cellulose and hemicelluloses, respectively [ 34 ]. These differences can be explained by the varying environmental conditions, such as light, temperature, and osmotic conditions, which can affect cellulose synthesis [ 35 ].…”

“…Similarly, argan pulp dry matter, protein, and fat contents have been reported in nine different regions. Depending on the region, dry matter content ranged from 83.75% to 89.82%, while fat and protein content accounted for 5.37% to 7.40% and 5.01% to 9.26%, respectively [ 34 ].…”

Argan pulp is an abundant byproduct from the argan oil process. It was investigated to study the feasibility of second-generation bioethanol production using, for the first time, enzymatic hydrolysis pretreatment. Argan pulp was subjected to an industrial grinding process before enzymatic hydrolysis using Viscozyme L and Celluclast 1.5 L, followed by fermentation of the resulting sugar solution by Saccharomyces cerevisiae. The argan pulp, as a biomass rich on carbohydrates, presented high saccharification yields (up to 91% and 88%) and an optimal ethanol bioconversion of 44.82% and 47.16% using 30 FBGU/g and 30 U/g of Viscozyme L and Celluclast 1.5 L, respectively, at 10%w/v of argan biomass.

The present work describes comparative dilute acid pretreatment of the argan pulp (residue produced during the argan oil extraction) used as an economical source for bioethanol production. Response surface methodology was used to optimize the pretreatment process and to explore the effect of operational parameters (acid concentration, temperature, time and biomass loading), depending on the acid type (HCl, H2SO4) and pretreatment approach, on total and reducing sugars recovery, in addition to phenolic compounds rate as inhibitors produced during pretreatment process. Experimental results predict an optimal yield of total and reducing sugars of 171.46 mg/ml and 54.83 mg/ml, respectively, were achieved at an optimized time of 30 min with 7% of sulfuric acid at 160°C using 40 % for biomass loading.

“…Dela é possível obter energia elétrica e biocombustíveis, como o etanol, cujo consumo é crescente em substituição dos derivados de petróleo como o óleo diesel e a gasolina (Smuga-Kogut, et al, 2019;Chohan, et al, 2020). Uma vantagem importante dos biocombustíveis, como o etanol, sobre os combustíveis derivados do petróleo é que (1) contribuem para a mitigação das emissões de GEE, (2) fornecem uma fonte de energia limpa e sustentável, (3) são biodegradáveis e contribuem para a sustentabilidade, e (4) aumentam a renda agrícola nos países em desenvolvimento (Zouhair et al, 2020).…”

A transformação de biomassas agroindustriais em bioetanol, além de ser uma rota alternativa para produção de combustíveis, traz uma valorização dos rejeitos e resíduos provenientes do processo. Este artigo relata a produção e caracterização física e química do bioetanol a partir do resíduo de biomassa mista, composta por cascas da banana Musa acuminata, da laranja Citrus sinensis e do maracujá Passiflora edulis f. flavicarpa. As amostras de mostos fermentados, B1 e B2, foram destilados após 24 h e 96 h, obtendo, respectivamente, 18,5% e 11% de rendimento alcoólico. O bioetanol produzido foi caracterizado através de paramentos físicos e químicos, como pH, condutividade elétrica, teor alcoólico, índice de acidez e sólidos totais de acordo com a Agência Nacional do Petróleo (ANP). Uma análise empregando a técnica de headspace acoplada a um cromatógrafo a gás com detector de massas (HS/GC-MS) foi realizada para identificação do etanol nas amostras. Os resultados encontrados nas análises de B1 e B2 foram, respectivamente, pH 3,75 e 3,64, índice de acidez 56,21 e 56,21 mg/L, condutividade 81,4 e 219 µS/cm, teor alcoólico 15,60 e 13,04 v/v e sólidos totais 0,0543 e 0,1465 mg/L. Os estudos das propriedades e características demonstraram a viabilidade de produzir etanol a partir de biomassa das frutas, sendo uma forma de agregar valor a estes resíduos.
