After forty years of research development, an overview solid-state fermentation (SSF), focusing on its applications, mainly the very recent papers last five years, is presented. This review comprises most important developed processes concerning production enzymes, biopulping processes, and traditional for food fermentation, such as Chinese daqu koji, industrial biomolecules organic acids, pigments, phenolic compounds, aromas biosorbents. SSF bioreactors design that has been reported, so...
Summary This study describes, for the first time, potential use of selected lactic acid bacteria (LAB) to conduct improved coffee bean fermentation during on‐farm wet processing. Among different strains tested, Lactobacillus plantarum LPBR01 showed a suitable production organic acids and flavour‐active esters in coffee‐pulp simulation medium was used as starter culture under field conditions. The results indicated that L. able establish an accelerated acidification process potentially...
Abstract Brazilian bioethanol is one of the most prominent biofuels produced on a large scale, representing 30% global fuel ethanol production share. Around 8.6 billion gallons were in 2019, second only to US same period (15.8 gallons). Obtained from sugarcane highly energy‐efficient process, biofuel, which can be used Brazil as 100% (hydrated, minimum mass content 92.5%) or volume proportion 27% (anhydrous ethanol) common gasoline, has contributed reduction oil dependency and CO 2...
Sugarcane ethanol production generates about 360 billion liters of vinasse, a liquid effluent with an average chemical oxygen demand 46,000 mg/L. Vinasse still contains 11% the original energy from sugarcane juice, but this is diluted. This residue, usually discarded or applied in fertigation, suitable substrate for anaerobic digestion (AD). Although technology not yet widespread—only 3% bioethanol plants used it Brazil past, most discontinuing process—the research continues. With biomethane...
Ethanol production from lignocellulosic biomasses raises a global interest because it represents good alternative to petroleum-derived energies and reduces the food versus fuel conflict generated by first generation ethanol. In this study, alkaline-acid pretreated brewers’ spent grain (BSG) was evaluated for ethanol after enzymatic hydrolysis with commercial enzymes. The obtained hydrolysate containing glucose concentration of 75 g/L adopted, dilution up 50 g/L, fermentation strain...
Hydrothermal carbonization (HTC) is a promising thermochemical process to convert residues into hydrochar. While conventional HTC utilizes one type of residue as raw material only, Co-HTC generally combines two. By mixing dry and wet wastes, can advantageously avoid water addition. Therefore, this work investigated the potential hydrochar derived from sawdust non-dewatered sewage sludge dye (methylene blue) adsorbent evaluated toxicity resulting (PW) on Daphnia magna. Three hydrochars were...
