“…Similarly, enzymatic hydrolysis of galactomannans like guar gum, 3 locust bean gum, 4 and Gleditsia sinensis gum 28 majorly produced DP2 and DP3 oligosaccharides. On the contrary, hydrolysis of copra meal and konjac glucomannan by endo-β-mannanase from Aspergillus quadrilineatus resulted in DP2 and DP4 and DP2 and DP5, respectively, as the major end products 8 while, Penicillium oxalicum SO endo-β-mannanase released DP7 as the major oligosaccharide from guar gum. 29 Fig.…”

“…6 In this context, copra meal has been hydrolyzed using endo-β-1,4-mannanases from microbial sources to produce β-manno-oligosaccharides to augment the growth of probiotic bacteria. 7,8 However, no study has been carried out to date that elucidates the structural features (composition, degree of polymerization, linkage) of purified β-manno-oligosaccharides from copra meal and their corresponding prebiotic potential for probiotic Lactobacillus spp. (isolated from human and food sources).…”

“…Mannans’ degradation is accomplished by various GHs (glycoside hydrolases) such as β-mannanase, β-mannosidase, β-glucosidase, acetyl-mannan-esterase, and α-galactosidase producing manno-oligosaccharides [ 48 ]. The later were utilized as prebiotics that enhance immune responses and modulate gut microbiota [ 49 ]. Yang et al identified two β-mannanase genes ( s331 and s16942 ) from S. chartarum that were expressed in Aspergillus niger with high protein titers and activities [ 50 ].…”

Fungi are renowned as a fountainhead of bio-metabolites that could be employed for producing novel therapeutic agents, as well as enzymes with wide biotechnological and industrial applications. Stachybotrys chartarum (black mold) (Stachybotriaceae) is a toxigenic fungus that is commonly found in damp environments. This fungus has the capacity to produce various classes of bio-metabolites with unrivaled structural features, including cyclosporins, cochlioquinones, atranones, trichothecenes, dolabellanes, phenylspirodrimanes, xanthones, and isoindoline and chromene derivatives. Moreover, it is a source of various enzymes that could have variable biotechnological and industrial relevance. The current review highlights the formerly published data on S. chartarum, including its metabolites and their bioactivities, as well as industrial and biotechnological relevance dated from 1973 to the beginning of 2022. In this work, 215 metabolites have been listed and 138 references have been cited.

“…Different studies have concluded that oligosaccharides prevent gut damage caused by pathogenic bacteria or a diet containing harmful chemicals such as lectin ( 48 ). The oligosaccharides enhance the population of probiotic bacteria and increase the production of short chain fatty acids (SCFA's), including acetate, propionate, and butyrate ( 7 , 49 ). These acids have an important role in increasing the transepithelial fluid transport and epithelial defense barrier and in decreasing mucosal inflammation and oxidative stress.…”

The gut microbiota in the human body is an important component that plays a pivotal role in the ability of the host to prevent diseases and recover from these diseases. If the human microbiome changes for any reason, it affects the overall functioning of the host. Healthy and vigorous gut microbiota require dietary fiber supplementation. Recently, oligosaccharides have been found to play a significant role in the modulation of microbiota. Several such oligosaccharides, i.e., xylooligosaccharides (XOS), mannooligosaccharides (MOS), and arabino-xylooligosaccharides (AXOS), are derived from hemicellulosic macromolecules such as xylan, mannan, and arabino-xylan, respectively. These oligosaccharides serve as substrates for the probiotic production of health-promoting substances (short-chain fatty acids, branched chain amino acids etc.), which confer a variety of health benefits, including the prevention of some dreaded diseases. Among hemicellulose-derived oligosaccharides (HDOs), XOS have been largely explored, whereas, studies on MOS and AXOS are currently underway. HDOs, upon ingestion, help reduce morbidities by lowering populations of harmful or pathogenic bacteria. The ATP-binding cassette (ABC) transporters are mainly utilized for the uptake of oligosaccharides in probiotics. Butyrate generated by the selective fermentation of oligosaccharides, along with other short-chain fatty acids, reduces gut inflammation. Overall, oligosaccharides derived from hemicelluloses show a similar potential as conventional prebiotics and can be supplemented as functional foods. This review summarizes the role of HDOs in the alleviation of autoimmune diseases (inflammatory bowel disease, Crohn's disease), diabetes, urinary tract infection, cardiovascular diseases, and antimicrobial resistance (AMR) through the modulation of the gut microbiota. The mechanism of oligosaccharide utilization and disease mitigation is also explained.
