Metatranscriptomic analyses reveal ruminal pH regulates fiber degradation and fermentation by shifting the microbial community and gene expression of carbohydrate-active enzymes

Animal Microbiome, 2021
Background Volatile fatty acids (VFA) generated from ruminal fermentation by microorganisms provide up to 75% of total metabolizable energy in ruminants.

Uncovering CAZyme Induction in the Thermophilic Fungus Thermoascus Aurantiacus [PDF]

, 2021
Abstract Background: Filamentous fungi are excellent lignocellulose degraders, which they achieve through producing carbohydrate active enzymes (CAZymes). CAZyme production is highly orchestrated and the application of –omics methods such as RNA-Seq has greatly expanded understanding of this important biotechnological process.

“CATAStrophy,” a Genome-Informed Trophic Classification of Filamentous Plant Pathogens – How Many Different Types of Filamentous Plant Pathogens Are There?

Frontiers in Microbiology, 2020
The traditional classification of fungal and oomycete phytopathogens into three classes – biotrophs, hemibiotrophs, or necrotrophs – is unsustainable. This study highlights multiple phytopathogen species for which these labels have been inappropriately ...

dbCAN-PUL: a database of experimentally characterized CAZyme gene clusters and their substrates [PDF]

Nucleic Acids Research, 2020
Abstract PULs (polysaccharide utilization loci) are discrete gene clusters of CAZymes (Carbohydrate Active EnZymes) and other genes that work together to digest and utilize carbohydrate substrates. While PULs have been extensively characterized in Bacteroidetes, there exist PULs from other bacterial phyla, as well as archaea and ...

High activity CAZyme cassette for improving biomass degradation in thermophiles [PDF]

Biotechnology for Biofuels, 2018
توفر الكائنات الحية الدقيقة المحبة للحرارة وإنزيماتها العديد من المزايا للتطبيق الصناعي على نظيراتها المحبة للوسطى. على سبيل المثال، تم عزل اللاهوائية شديدة الحرارة، Caldicellulosiruptor bescii، مؤخرًا من الينابيع الساخنة في كامتشاتكا، سيبيريا، وتبين أن لها نشاطًا عالي التحلل. بالإضافة إلى ذلك، فهي واحدة من عدد قليل من الكائنات الحية الدقيقة التي تعتبر

dbCAN-seq update: CAZyme gene clusters and substrates in microbiomes

Nucleic Acids Research, 2022
Abstract Carbohydrate Active EnZymes (CAZymes) are significantly important for microbial communities to thrive in carbohydrate rich environments such as animal guts, agricultural soils, forest floors, and ocean sediments. Since 2017, microbiome sequencing and assembly have produced numerous metagenome assembled genomes (MAGs).

Genome-Wide Comparison of Carbohydrate-Active Enzymes (CAZymes) Repertoire of Flammulina ononidis

Mycobiology, 2018
Whole-genome sequencing of Flammulina ononidis, a wood-rotting basidiomycete, was performed to identify genes associated with carbohydrate-active enzymes (CAZymes). A total of 12,586 gene structures with an average length of 2009 bp were predicted by the

Variation of Carbohydrate-Active Enzyme Patterns in the Gut Microbiota of Italian Healthy Subjects and Type 2 Diabetes Patients

Frontiers in Microbiology, 2017
The human gut microbiota (GM) has been associated, to date, with various complex functions, essentials for the host health. Among these, it is certainly worth noting the degradation of the so-called microbiota-accessible carbohydrates (MACs), which the ...
