“…Increase in beta-glucosidase was also observed in long-term organically fertilized paddy fields using composted farmyard manure. Endo-β-1,4-xylanase hydrolyzes β-1,4 bonds in plant xylan found in hemicellulose [55]. Also, superoxide dismutase among plant growth promoting enzymes was high in oil cake amended soil.…”

Organic fertilizer application in agricultural land is known to improve soil microbial processes, fertility, and yield. In particular, stable changes in soil chemical composition through multi-year fertilization of organic fertilizers are thought to cause changes in the microbial community. Here, the effects of oil cake amendments (OC) on soil bacterial diversity, community profile and enzyme activity were evaluated and compared to those amended with chemical fertilizer (NPK). The comparison of diversity indices between OC and NPK amended soils shows that application of oil cake has increased microbial diversity potentially with an increase in the number of different microbial groups. The ordination plot distinguished and clustered both treatments showing differential effects of soils chemical factors on the microbial communities of each treatment. Proteobacteria, Verrucomicrobia and Bacteriodetes were significantly abundant in OC amended soil than in the NPK received soil, indicating alterations in community structure, composition, and diversity con-current to the changes in pH, Ca and Mg contents of the soil. These shifts in bacterial community structure and composition could also be observed from the phylum to the genus level in both NPK and OC amended soils partially explained by differences in soil chemical factors. The OC soil compared to the NPK amended soil also contain significantly higher abundance of predicted genes corresponding to enzymes related to biogeochemical cycling, decomposition and plant growth promotion. Collectively, these results support the use of an unconventional organic fertilizer positively altering bacterial populations in jujube orchards. The application of oil cake-based organic fertilizer improved microbial diversity and enhanced potential ecosystem functions related to bio-geochemical cycles, mineralization and plant growth promotion.

“…Based on the mechanism of action and binding to substrate, xylanases can also be classified into different enzymes that constitute its enzymatic system, namely: endo-β-1,4-xylanases, β-D-xylosidases, α-glucuronidases, arabinases, acetyl xylan esterases, ferulic acid esterases and p-coumaric acid esterase [ 42 ]. Endo-β-1,4-xylanases (EC 3.2.1.8), the main components of xylanases, are those with endoxylanase activity, which break β-1,4-glycosidic bonds within the xylan chain, producing xylooligosaccharides and xylose units [ 60 , 92 ]. β-D-xylosidases (EC 3.2.1.37) act on these xylooligosaccharides non-reducing ends generated from xylan, successively removing their D-xylose residues [ 60 , 93 , 94 ].…”

Human population growth, industrialization, and globalization have caused several pressures on the planet’s natural resources, culminating in the severe climate and environmental crisis which we are facing. Aiming to remedy and mitigate the impact of human activities on the environment, the use of lignocellulolytic enzymes for biofuel production, food, bioremediation, and other various industries, is presented as a more sustainable alternative. These enzymes are characterized as a group of enzymes capable of breaking down lignocellulosic biomass into its different monomer units, making it accessible for bioconversion into various products and applications in the most diverse industries. Among all the organisms that produce lignocellulolytic enzymes, microorganisms are seen as the primary sources for obtaining them. Therefore, this review proposes to discuss the fundamental aspects of the enzymes forming lignocellulolytic systems and the main microorganisms used to obtain them. In addition, different possible industrial applications for these enzymes will be discussed, as well as information about their production modes and considerations about recent advances and future perspectives in research in pursuit of expanding lignocellulolytic enzyme uses at an industrial scale.
