Antibiotics and Carbohydrate-Containing Drugs Targeting Bacterial Cell Envelopes: An Overview

Pharmaceuticals, Journal Year: 2022, Volume and Issue: 15(8), P. 942 - 942

Published: July 29, 2022

Certain bacteria constitute a threat to humans due their ability escape host defenses as they easily develop drug resistance. Bacteria are classified into gram-positive and gram-negative according the composition of cell membrane structure. Gram-negative have an additional outer (OM) that is not present in counterpart; latter instead hold thicker peptidoglycan (PG) layer. This review covers main structural functional properties wall polysaccharides (CWPs) PG. Drugs targeting CWPs discussed, both noncarbohydrate-related (β-lactams, fosfomycin, lipopeptides) carbohydrate-related (glycopeptides lipoglycopeptides). Bacterial resistance these drugs continues evolve, which calls for novel antibacterial approaches be developed. The use carbohydrate-based vaccines valid strategy prevent bacterial infections also addressed.

Overview of recent researches on nitrifying microorganisms in soil

Soil Science & Plant Nutrition, Journal Year: 2021, Volume and Issue: 67(6), P. 619 - 632

Published: Oct. 17, 2021

Nitrogen cycle, a most important elemental cycle in earth ecosystem, is carried out by three major microbial processes including nitrogen fixation, nitrification and denitrification. Nitrification particularly agricultural soil ecosystems because it involved loss, groundwater pollution leaching, greenhouse gas nitrous oxide emission. Recent genomic, metagenomic physiological analysis of nitrifying microorganisms gives new insights into their ecology functions soils. In the last decade, there have been number findings regarding nitrification. The discovery archaea complete bacteria has overturned conventional theory that driven ammonia-oxidizing nitrite-oxidizing bacteria. Each newly discovered unique properties, for example, different affinity ammonia. These shown to actually play roles Soil conditions practices such as fertilization tillage influence contribution each microorganism activity addition, inhibition technologies developed prevent loss fertilizer This review provides an overview recent researches on diversity characteristics microorganisms, factors affecting soil, involvement emissions, control technologies.

Niche Differentiation of Comammox Nitrospira in the Mudflat and Reclaimed Agricultural Soils Along the North Branch of Yangtze River Estuary

Frontiers in Microbiology, Journal Year: 2021, Volume and Issue: 11

Published: Jan. 14, 2021

The discovery of complete ammonia oxidation (comammox), oxidizing to nitrate via nitrite in a single organism, has redefined the traditional recognition two-step nitrification driven by two functional groups (ammonia-oxidizing and nitrite-oxidizing microorganisms). However, understanding distribution niche differentiation comammox Nitrospira estuarine mudflats their reclaimed agricultural soils is still limited. Here, we investigated abundance, diversity community structures northern Yangtze River estuary. Quantitative PCR showed abundances amoA genes were lower than that ammonia-oxidizing bacteria (AOB) nearly all samples. Amplicon sequencing revealed significantly ( P < 0.001) different between original soils, indicating among clades (clade A.1, clade A.2, B). A.1 was dominant group mudflats, while B predominated soils. members A.2 could be clearly divided into groups, mudflat-preferred soil-preferred suggesting more complicated ecological preferences within this sub-clade. Furthermore, it demonstrated salinity, organic matter (OM) NO 3 – -N had influence on environment. Clade half positively correlated with negatively concentrations OM -N. In contrast, other exact opposite pattern: negative correlation salinity positive co-occurrence network operational taxonomic units (OTUs) same (sub-)clade mostly correlated, similar from . Taken together, our results ecosystems where primary factors responsible for distinct patterns.

Competition between ammonia-oxidizing archaea and complete ammonia oxidizers from freshwater environments

Applied and Environmental Microbiology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 13, 2024

Nitrification is a key process in the global nitrogen cycle. Aerobic ammonia oxidizers play central role cycle by performing first step of nitrification. Ammonia-oxidizing archaea (AOA) and complete (comammox) are dominant nitrifiers environments with low ammonium availability. While AOA have been studied for almost 20 years, comammox were only discovered 8 years ago. Until now, there has gap our understanding whether can co-exist or if one strain would be under ammonium-limiting conditions. Here, we present study characterizing competition between freshwater varying substrate concentrations. Our results will help elucidating niches two lakes.
