The link between ancient microbial fluoride resistance mechanisms and bioengineering organofluorine degradation or synthesis

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: May 30, 2024

Abstract Fluorinated organic chemicals, such as per- and polyfluorinated alkyl substances (PFAS) fluorinated pesticides, are both broadly useful unusually long-lived. To combat problems related to the accumulation of these compounds, microbial PFAS organofluorine degradation biosynthesis less-fluorinated replacement chemicals under intense study. Both efforts undermined by substantial toxicity fluoride, an anion that powerfully inhibits metabolism. Microorganisms have contended with environmental mineral fluoride over evolutionary time, evolving a suite detoxification mechanisms. In this perspective, we synthesize emerging ideas on defluorination/fluorination resistance mechanisms identify best approaches for bioengineering new degrading making compounds.

Efficacious use of Micrococcus yunnanensis GKSM13 for the growth of rice seedlings under copper stress with elucidation into genomic traits

Current Plant Biology, Journal Year: 2023, Volume and Issue: 37, P. 100318 - 100318

Published: Dec. 30, 2023

Rice is widely cultivated worldwide, and beneficial bactrial colonization are particularly desirable for sustainable agriculture because they promote growth production by preventing excessive heavy metal contamination. The present study was conducted with the aim of improving rice seedlings (MTU1010 variety) under copper (Cu) stress using Cu-tolerant plant promoting bacteria (PGPB) Micrococcus yunnanensis GKSM13. Strain GKSM13 able to produce factors (PGPFs) such as indole-3-acetic acid (IAA), gibberellin A3 (GA3) ammonia, accumulate proline, fix N2, inhibit 2,2-Diphenyl-1-picrylhydrazyl (DPPH). treated Cu2+ co-inoculated significantly improved their in morphological biochemical aspects. When analysed field emission scanning electron microscope (FE-SEM), found be associated root cells form large number coccoid cells. uptake reduced 57.5% presence treatment also Cu-induced oxidative activating antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APOX) glutathione (GPOX), which supported DPPH inhibition reduction malondialdehyde (MDA) accumulation. Insight into genome strain reveals tryptophan (trp), ent-kaurene, cyanase (cyn), phosphate-specific transport (pst), major facilitator superfamily transporter (MFS), sulphate (cys), proline (pro) SOD (sod) genes, responsible alleviating stress. Therefore, application M. could provide a agricultural solution Cu-affected mining areas.

A heavy metal hypertolerant plant growth-promoting bacterium was isolated from the arsenic-contaminated garden soil of Bhagobangola I block (Murshidabad district). Metagenomic classification identified bacterial isolate as a member genus Microbacterium. Taxonomic assessment strain revealed its maximum average nucleotide identity (89.99 %) with Microbacterium paraoxydans DSM 15019. Prokaryotic genome annotation performed by Prokka, DFAST and RAST. The entire consisted 3365911 bases 69.90 % GC content. Prokka detected 3216 coding sequences (1461 hypothetical sequences), 3283 genes, 10 miscellaneous RNAs, 3 rRNAs, 53 tRNAs 1 tmRNA in genome. 3257 (1217 rRNA tRNA RAST 3285 49 RNAs Only 25 these could be categorised subsystems. In RAST, 789 32 were considered non-hypothetical hypothetical, respectively. genes gene clusters responsible for arsenic resistance (arsR, arsB, arsC, acr1, acr2 acr3), tolerance to other metals (copper, manganese, zinc, etc.) growth promotion (auxin biosynthesis, siderophore-mediated iron acquisition, phosphate polyphosphate metabolism, trehalose also bioremediation potential nature confirmed silver diethyl dithio carbamate (SDDC) method pot experiments, aforementioned traits point towards tool biofertilizer reducing toxicity promoting growth.
