Biopesticide and biofertilizer potential of tropical earthworm vermicast tea

Notulae Scientia Biologicae, 2023
The adverse effects of chemical pesticides have continued to drive the search for safe, biological alternatives. Studies on biopesticide potential of earthworm casts have remained largely limited to those of temperate earthworms. We evaluated the insect

Starmerella bacillaris Strains Used in Sequential Alcoholic Fermentation with Saccharomyces cerevisiae Improves Protein Stability in White Wines

Fermentation, 2022
Haze can appear in white wines as a result of the denaturation and subsequent aggregation of grape pathogenesis-related (PR) proteins. Yeast cell-wall polysaccharides, particularly mannoproteins, represent a promising strategy to reduce the incidence of ...

Bovine Serum Chitinase [PDF]

European Journal of Biochemistry, 1979
1. A glycol-chitin-splitting enzyme without lysozyme (muramidase) activity has been found in calf serum. The enzyme also degrades colloidal chitin and is thus a true chitinase, 1,4-beta-poly-N-acetylglucosaminidase, without exo-beta-N-acetylglucosaminidase effect. 2.

Novel domain-structure-containing chitinases A and B of Bacillus velezensis produced by recombinant Escherichia coli cells: Synergism on chitin degradation and their potential in suppressing Candida albicans cell germination

Journal of Genetic Engineering and Biotechnology
Bacillus velezensis RB.IBE29 harbors two chitinases belonging to the glycoside hydrolase family 18 and exhibiting a novel domain structure. The roles of these chitinases in crop production have been reported; nevertheless, their contribution to ...

Synergistic Action of a Metalloprotease and a Serine Protease from Fusarium oxysporum f. sp. lycopersici Cleaves Chitin-Binding Tomato Chitinases, Reduces Their Antifungal Activity, and Enhances Fungal Virulence

Molecular Plant-Microbe Interactions, 2015
As part of their defense strategy against fungal pathogens, plants secrete chitinases that degrade chitin, the major structural component of fungal cell walls.

Purificação e caracterização da quitinase de uva (Vitis vinífera L. cv Red Globe) para a produção de quitosana a partir de quitina de camarão

Química Nova, 2010
Chitinase is produced by a wide variety of plants as a defense against peste attacks. In this study, grape chitinases were purified 16 times by fractionation in 80% ammonium sulfate followed by dialysis and filtration.

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.
