A polyphasic approach to the study of chitinolytic bacteria in soil [PDF]

Chitin is the most abundant nitrogen-containing polymer in nature, with >1x10^10 tonnes produced annually in terrestrial and marine habitats. Chitinolytic bacteria are able to degrade this recalcitrant substrate through a multiplicity of chitinases.

N-Acetyl Glucosamine Obtained from Chitin by Chitin Degrading Factors in Chitinbacter tainanesis

, 2011
A novel chitin-degrading aerobe, Chitinibacter tainanensis, was isolated from a soil sample from southern Taiwan, and was proved to produce N-acetyl glucosamine (NAG).

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Complement Component 3C3 and C3a Receptor Are Required in Chitin-Dependent Allergic Sensitization to Aspergillus fumigatus but Dispensable in Chitin-Induced Innate Allergic Inflammation

mBio, 2013
Levels of the anaphylatoxin C3a are increased in patients with asthma compared with those in nonasthmatics and increase further still during asthma exacerbations.

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Chitins and Chitosans as Immunoadjuvants and Non-Allergenic Drug Carriers

Marine Drugs, 2010
Due to the fact that some individuals are allergic to crustaceans, the presumed relationship between allergy and the presence of chitin in crustaceans has been investigated.

Chitin-binding capacity of rLdpA.

After incubation of serially diluted rLdpA (2.5–40 μg) with chitin (1 mg) in 100 μL of PBS, rLdpA in the supernatant (sup.) and sediment (sed.) was evaluated by SDS-PAGE. (TIF)

Chitin soil amendment triggers systemic plant disease resistance through enhanced pattern‐triggered immunity [PDF]

Chitin triggers localised and systemic plant immune responses, making it a promising treatment for sustainable disease resistance. However, the precise molecular mechanisms underlying chitin‐induced systemic effects in plants remain unknown.
