Mangroves are complex land-sea transition ecosystems whose microbiota essential for their nutrient recycling and conservation. Brazil is the third-largest estuarine area in world "Baía de Todos os Santos" (BTS) one of largest bays country, with wide anthropogenic exploration. Using a metagenomic approach, we investigated composition functional adaptability as signatures microbiome pristine anthropized areas BTS, including those under petroleum refinery influence. The taxonomic analysis showed dominance sulfate-reducing Desulfobacteraceae, Rhodobacteraceae, Flavobacteriaceae. Taxa were significantly diverse between disturbed areas. Disturbed mangroves notary increase abundance halophilic, sulfur-related, hydrocarbon-degrading genera decrease diatoms compared to area. metabolic profile BTS was correlated differentially abundant microbiota. Two ecological scenarios observed: marked by functions central metabolism associated biomass degradation another mechanisms microbial pollution conditions environmental degradation.

Polyhydroxybutyrate (PHB)-Based Biodegradable Polymer from Agromyces indicus: Enhanced Production, Characterization, and Optimization

Polymers, Journal Year: 2022, Volume and Issue: 14(19), P. 3982 - 3982

Published: Sept. 23, 2022

Recently, there has been significant interest in bio-based degradable plastics owing to their potential as a green and sustainable alternative synthetic due biodegradable properties. Polyhydroxybutyrate (PHB) is polymer that produced by bacteria archaea carbon energy reserves. Due its rapid degradation natural environments, it can be considered plastic alternative. In the present study, dye-based procedure was used screen PHB-producing isolated from mangrove soil samples. Among seven isolates, Agromyces indicus (A. indicus), identified means of 16S rRNA analysis, accumulated highest amount PHB. The extracted characterized UV-Vis spectrophotometer, Fourier-transform infrared (FTIR) spectroscopy, for presence phbB gene, which confirmed structure maximum PHB production A. achieved after 96 h incubation at pH 8.0 35 °C 2% NaCl, with glucose peptone nitrogen sources, respectively. strain found capable accumulating when various cheap agricultural wastes, such rice, barley, corn, wheat bran, were sources. response surface methodology (RSM) through central composite design (CCD) optimizing synthesis highly efficient augmenting yields. As result optimum conditions obtained RSM, this increase content approximately 1.4-fold compared an unoptimized medium, would substantially lower cost. Therefore, isolate B2 may regarded one best candidates industrial remove environmental concerns associated plastic.

Effects of Degradation on Microbial Communities of an Amazonian Mangrove

Microorganisms, Journal Year: 2023, Volume and Issue: 11(6), P. 1389 - 1389

Published: May 25, 2023

Mangroves provide a unique ecological environment for complex microbial communities, which play important roles in biogeochemical cycles, such as those carbon, sulfur, and nitrogen. Microbial diversity analyses of these ecosystems help us understand the changes caused by external influences. Amazonian mangroves occupy an area 9000 km2, corresponding to 70% Brazil, on studies biodiversity are extremely scarce. The present study aimed determine community structure along PA-458 highway, fragmented mangrove zone. Mangrove samples were collected from three zones, (i) degraded, (ii) process recovery, (iii) preserved. Total DNA was extracted submitted 16S rDNA amplification sequencing MiSeq platform. Subsequently, reads processed quality control analyses. most abundant phyla Proteobacteria, Firmicutes, Bacteroidetes all locations, but significantly different proportions. We observed considerable reduction degraded Important genera involved nitrogen metabolism absent or dramatically reduced this Our results show that human impact areas, construction has resulted loss biodiversity.

Abstract Characterization of ubiquitous microorganisms has encountered many challenges, such as determining unknown microorganisms, their interactions, and unresolved functions in natural environments. Evolution metagenomics tools, however, revolutionized assessment methodologies. Metagenomics enabled unearthing the secret microbial treasure a culture-independent manner proven more successful than conventional It provided an unparalleled platform for functional taxonomic characterization microbiota dwellings altered lakes. Of late, research articles have used to understand microorganisms’ role environmental clean-up. Consequently, these studies been consolidated form review articles. However, most them are related characterization, procedure metagenomics, wastewater treatment, whereas only few were directly lake bioremediation. Therefore, this highlights applications unraveling potential rejuvenation. A paradigm shift from recent breakthroughs is also emphasized. The discusses merits, demerits previous molecular techniques, understanding world contaminated Furthermore, metagenomic Finally, future directions proposed designing possible strategies
