Screening and identification of marine alginate lyase-producing bacteria and optimization of enzyme production conditions [PDF]

Zhongguo niangzao
Alginate lyases are mostly derived from marine bacteria with unique living environments. Using sodium alginate as the sole carbon source, a strain with high-yield alginate lyase from 56 strains of marine bacteria was screened using primary screening by ...

Microbial ecological memory of recurrent drought enhances host stress tolerance through enrichment of plant‐beneficial bacteria

iMetaOmics, EarlyView.
Recurrent desiccation induced niche‐specific microbial ecological memory in the green part of Calohypnum plumiforme, marked by enrichment of plant‐beneficial bacteria, especially Methylobacterium and Sphingomonas, and functional shifts toward symbiosis and stress protection, potentially enhancing host tolerance within a “holobiont ecology memory ...

Comparative Characterization of Aspergillus Pectin Lyases by Discriminative Substrate Degradation Profiling

Frontiers in Bioengineering and Biotechnology, 2020
Fungal genomes often contain several copies of genes that encode carbohydrate active enzymes having similar activity. The copies usually have slight sequence variability, and it has been suggested that the multigenecity represents distinct reaction ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Structural And Functional Characterization Of Ulvan Degrading Polysaccharide Lyase Enzymes

The FASEB Journal, 2018
Ulvans are the sulfated cell wall polysaccharide present in marine green algae. Ulvan polysaccharides are composed mainly of 3‐sulfated rhamnose, glucuronic acid, iduronic acid and xylose. The sulfation pattern in ulvan resemble glycosaminoglycans in vertebrates.

The O-specific polysaccharide lyase from the phage LKA1 tailspike reduces Pseudomonas virulence [PDF]

Scientific Reports, 2017
AbstractPseudomonas phage LKA1 of the subfamily Autographivirinae encodes a tailspike protein (LKA1gp49) which binds and cleaves B-band LPS (O-specific antigen, OSA) of Pseudomonas aeruginosa PAO1. The crystal structure of LKA1gp49 catalytic domain consists of a beta-helix, an insertion domain and a C-terminal discoidin-like domain.

Contribution of cell wall modifying enzymes on the texture of fleshy fruits: The example of apple [PDF]

Journal of the Serbian Chemical Society, 2013
Cell walls consist of polysaccharide assemblies (pectin, hemicelluloses and cellulose), whose structure and interactions vary depending on fruit genetic, and its stage and conditions of development.

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and

Insights into the mechanism of substrate specificity in a novel PL15_3 subfamily oligo-alginate lyase VBAly15A

Applied and Environmental Microbiology
Alginate is a major component of brown algae cell walls and can be degraded via β-elimination by alginate lyases. These enzymes are classified into polysaccharide lyases and oligo-alginate lyases (Oals), with Oals mainly represented by the PL15 and PL17 ...

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...
