“…In [130], a microbial community is operated in an anaerobic chamber reactor to treat ethanol distillery vinasse. In Brito Codato et al [131], the researchers ferment ethanol from hydrolyzed sugarcane bagasse after being grown in solid-state with vinasse as an impregnation solution by a consortium of A. niger and T. reesei for ethanol production. In [132], vinasse, cachaça, and straw deacetylation pretreatment liquor were used to generate methane by co-digestion.…”

Vinasse is a toxic pollutant if it is poured into the ecosystem indiscriminately; despite this, it integrates components that make it valuable in nutrients and water. However, its use has been questioned due to the costs involved in its purification. This systematic review focuses on the valorization of vinasse from the studies performed for its post-industrial use. Trends in vinasse management and bioproduct development were analyzed. The PRISMA statement was used as a formal guide for collecting and analyzing 131 studies from 2018 to 2022. We determined that biological processes are the most used to obtain the benefits of vinasse, obtaining up to three post-industrial bioproducts. While it is true that there is a predominant trend of studies focused on the generation of biofuels, it must be noted that the beginning of the sucro-alcohol chain was the agricultural field. In this sense, we determine that 14% of the studies treat vinasse for agricultural reuse purposes, so, under Circular Economy principles, the reincorporation of vinasse into the agricultural field to take advantage of its goodness in nutrients and minerals as a sustainable and eco-efficient alternative should be a research trend that accelerates the consumption of vinasse generated in alcohol distilleries.

“…The most important enzymes in cellulose and hemicellulose degradation are endoand exoglucanase and xylanase, as mentioned earlier. Pretreated corn cobs are a complex lignocellulosic material that have a high glucan and small xylan content and as such were used as the inducer of enzyme production in the sequential solid-state and submerged cultivation of the selected fungal strains [15,22,[60][61][62][63][64][65]. The activity of glucanases and xylanases were monitored during the cultivation of F. oxysporum f.sp.…”

Screening of Lignocellulolytic Enzyme Activities in Fungal Species and Sequential Solid-State and Submerged Cultivation for the Production of Enzyme Cocktails

Various fungal species can degrade lignocellulolytic materials with their enzyme cocktails composed of cellulolytic and lignolytic enzymes. In this work, seven fungal species (Mucor indicus DSM 2185, Paecilomyces variotii CBS 372.70, Myceliophthora thermophila CBS 663.74, Thielavia terrestris CBS 456.75, Botryosphaeria dothidea JCM 2738, Fusarium oxysporum f.sp. langenariae JCM 9293, and Fusarium verticillioides JCM 23107) and four nutrient media were used in the screening for effective lignocellulose degrading enzymes. From the seven tested fungi, F. oxysporum and F. verticilliodes, along with nutrient medium 4, were selected as the best medium and producers of lignocellulolytic enzymes based on the determined xylanase (>4 U mg−1) and glucanase activity (≈2 U mg−1). Nutrient medium 4 supplemented with pretreated corn cobs was used in the production of lignocellulolytic enzymes by sequential solid-state and submerged cultivation of F. oxysporum, F. verticilliodes, and a mixed culture of both strains. F. oxysporum showed 6 times higher exoglucanase activity (3.33 U mg−1) after 5 days of cultivation in comparison with F. verticillioides (0.55 U mg−1). F. oxysporum also showed 2 times more endoglucanase activity (0.33 U mg−1). The mixed culture cultivation showed similar endo- and exoglucanase activities compared to F. oxysporum (0.35 U mg−1; 7.84 U mg−1). Maximum xylanase activity was achieved after 7 days of cultivation of F. verticilliodes (≈16 U mg−1), while F. oxysporum showed maximum activity after 9 days that was around 2 times lower compared to that of F. verticilliodes. The mixed culture achieved maximum xylanase activity after only 4 days, but the specific activity was similar to activities observed for F. oxysporum. It can be concluded that both fungal strains can be used as producers of enzyme cocktails for the degradation of lignocellulose containing raw materials, and that corn cobs can be used as an inducer for enzyme production.
