“…Furthermore, α‐ d ‐GlcUase showed a fluctuant decreasing behaviour to reach a maximum value of the enzymatic activity of 5.8 × 10 −3 U mg −1 . The pH considered the optimum value was 6 reported (Broeker et al ., 2018; Tamayo et al ., 2021).

SummarySolid‐state fermentation (SSF) can improve the availability of nutrients in food products by converting complex molecules into simpler ones with the help of microorganisms. The present research focuses on using the fungi Aspergillus oryzae in SSF to ferment grasshoppers (Sphenarium purpurascens). The fermentation was carried out for eight days, and kinetic growth, enzyme, and bioactive compounds (TPC, ABTS, and DPPH) production were monitored. Second order equation modelled the growth of A. oryzae on a grasshopper substrate. During fermentation, a protein increase of 50% was obtained after day 4. TPC, ABTS, DPPH scavenging activity percentage, β‐glucan, and amylase activity increased 116%, 70%, 10%, 380%, and 629.6% at 8, 0.5, 3, 4, and 7 days, respectively, as maximum during fermentation. Results herein clearly indicate that Aspergillus oryzae could use Sphenarium purpurascens as a substrate in SSF to produce enzymes and bioactive compounds of industrial and nutritional interest.

“…Cutaneotrichosporon curvatus has been reported to be useful in the production of sustainable single cell oil from undetoxified lignocellulosic hydrolysates [ 45 , 46 ]. The genus Aspergillus contains some well-known members capable of degrading cellulose and using other plant materials as a source for alpha-glucuronidase [ 47 , 48 ]. Naganishia diffluens is another well-documented fungal taxon with cellulose degradation capabilities that has been investigated to explore its enzymatic production potential [ 49 , 50 ].…”

The lack of efficient ways to dispose of lignocellulosic agricultural residues is a serious environmental issue. Low temperatures greatly impact the ability of organisms to degrade these wastes and convert them into nutrients. Here, we report the isolation and genomic characterization of a microbial consortium capable of degrading corn straw at low temperatures. The microorganisms isolated showed fast cellulose-degrading capabilities, as confirmed by scanning electron microscopy and the weight loss in corn straw. Bacteria in the consortium behaved as three diverse and functionally distinct populations, while fungi behaved as a single population in both diversity and functions overtime. The bacterial genus Pseudomonas and the fungal genus Thermoascus had prominent roles in the microbial consortium, showing significant lignocellulose waste-degrading functions. Bacteria and fungi present in the consortium contained high relative abundance of genes for membrane components, with amino acid breakdown and carbohydrate degradation being the most important metabolic pathways for bacteria, while fungi contained more genes involved in energy use, carbohydrate degradation, lipid and fatty acid decomposition, and biosynthesis.

“…Aspergillus oryzae, for instance, has been notably certified as a safe fungal species in the synthesis of various industrial enzymes for use in the food-processing industries [ 10 , 11 ]. Several species of Aspergillus have been found to possess the Alfa-glucuronidase enzyme, which is an essential biocatalyst in the biotransformation of lignocellulosic agro-industrial wastes into biofuels [ 12 ]. Filamentous fungi species, especially A. niger , among other microorganisms, are known to synthesize phytases enzyme, a form of phosphatases that is used as additives in animal feed and for production of ethanol in food and chemical industry, while the alkaline phosphatases, an enzyme derived from Aspergillus species, such as A. fumigatus, were reported to be an indispensable biotechnological tool for probing of nonisotopic, nucleic acids dephosphorylation, enzyme-linked immunoabsorbent assays (ELISA), and labelling of proteins [ 13 , 14 ].…”

Cytochrome P450s (P450ome) constitute an extended superfamily group of heme-thiolate enzymes identified in all biological domains. P450omes play a critical role in the oxidation of steroids and fatty acids, xenobiotic degradation of hydrophobic compounds, biosynthesis of hormones, and primary and secondary metabolism in organisms. Aspergillus species are among the most economically important fungal organisms in human medicine, industry, and agriculture worldwide. Exploring insight on the genome-wide annotations of cytochrome P450s in Aspergillus species is necessary for their biosynthetic applications. In this present study, we report the identification of 306 cytochrome P450s and their robust profiling in eight notable Aspergillus species (A. carbonarius, A. clavatus, A. flavus, A. fumigatus, A. nidulans, A. niger, A. oryzae, and A. terreus). Based on the evolutionary relationship, the Aspergillus P450s families clustered into 15 clades, with clades V, I, and XIII recording higher percentages (17.3%, 15.00%, and 14.71%, respectively) of Cyp families. Cyps were classified into 120 families 64 clans, and their putative functions were also elucidated. P450s were predicted to be located in 13 subcellular components, but the endoplasm reticulum was the dominant location across the eight Aspergillus species. Cyps genes of Aspergillus species were associated with seven secondary metabolism-related gene clusters. Elucidating the genome-wide annotations of P450s enzymes in Aspergillus species will form vital potential biotechnological tools that could be harnessed for industrial, pharmaceutical, and agricultural use.
