Horizontal Gene Transfer of Antibiotic Resistance Genes in Biofilms

Antibiotics, Год журнала: 2023, Номер 12(2), С. 328 - 328

Опубликована: Фев. 4, 2023

Most bacteria attach to biotic or abiotic surfaces and are embedded in a complex matrix which is known as biofilm. Biofilm formation especially worrisome clinical settings it hinders the treatment of infections with antibiotics due facilitated acquisition antibiotic resistance genes (ARGs). Environmental now considered pivotal for driving biofilm formation, biofilm-mediated development dissemination. Several studies have demonstrated that environmental biofilms can be hotspots dissemination ARGs. These encoded on mobile genetic elements (MGEs) such conjugative mobilizable plasmids integrative (ICEs). ARGs rapidly transferred through horizontal gene transfer (HGT) has been shown occur more frequently than planktonic cultures. models promising tools mimic natural study via HGT. This review summarizes state-of-the-art techniques visualize three main HGT mechanisms biofilms: transformation, transduction, conjugation.

Economic significance of biofilms: a multidisciplinary and cross-sectoral challenge

npj Biofilms and Microbiomes, Год журнала: 2022, Номер 8(1)

Опубликована: Май 26, 2022

Abstract The increasing awareness of the significance microbial biofilms across different sectors is continuously revealing new areas opportunity in development innovative technologies translational research, which can address their detrimental effects, as well exploit benefits. Due to extent affected by biofilms, capturing real financial impact has been difficult. This perspective highlights this globally, based on figures identified a recent in-depth market analysis commissioned UK’s National Biofilms Innovation Centre (NBIC). outputs from and workshops organised NBIC its research strategic themes have revealed breath opportunities for biofilms. However, there are still many outstanding scientific technological challenges must be addressed order catalyse these opportunities. discusses some challenges.

Plant Growth-Promoting Bacteria (PGPB) with Biofilm-Forming Ability: A Multifaceted Agent for Sustainable Agriculture

Diversity, Год журнала: 2023, Номер 15(1), С. 112 - 112

Опубликована: Янв. 13, 2023

Plant growth-promoting bacteria (PGPB) enhance plant growth, as well protect plants from several biotic and abiotic stresses through a variety of mechanisms. Therefore, the exploitation PGPB in agriculture is feasible it offers sustainable eco-friendly approaches to maintaining soil health while increasing crop productivity. The vital key application its effectiveness colonizing roots phyllosphere, developing protective umbrella formation microcolonies biofilms. Biofilms offer benefits PGPB, such enhancing resistance adverse environmental conditions, protecting against pathogens, improving acquisition nutrients released environment, facilitating beneficial bacteria–plant interactions. bacterial biofilms can successfully compete with other microorganisms found on surfaces. In addition, plant-associated are capable colonization sites, cycling nutrients, pathogen defenses, tolerance stresses, thereby agricultural productivity yields. This review highlights role surfaces strategies used by biofilm-forming PGPB. Moreover, factors influencing biofilm at root shoot interfaces critically discussed. will pave formulations addressing challenges related their efficacy competence for sustainability.

Pseudomonas putida mediates bacterial killing, biofilm invasion and biocontrol with a type IVB secretion system

Nature Microbiology, Год журнала: 2022, Номер 7(10), С. 1547 - 1557

Опубликована: Сен. 19, 2022

Many bacteria utilize contact-dependent killing machineries to eliminate rivals in their environmental niches. Here we show that the plant root colonizer Pseudomonas putida strain IsoF is able kill a wide range of soil and plant-associated Gram-negative with aid type IVB secretion system (T4BSS) delivers toxic effector into bacterial competitors manner. This extends targets T4BSSs-so far thought transfer effectors only eukaryotic cells-to prokaryotes. Bioinformatic genetic analyses showed this machine entirely encoded by kib gene cluster located within rare genomic island, which was recently acquired horizontal transfer. P. utilizes not as defensive weapon but also an offensive invade existing biofilms, allowing persist its natural environment. Furthermore, can protect tomato plants against phytopathogen Ralstonia solanacearum T4BSS-dependent manner, suggesting be exploited for pest control sustainable agriculture.

Biofilm formation in xenobiotic-degrading microorganisms

Critical Reviews in Biotechnology, Год журнала: 2022, Номер 43(8), С. 1129 - 1149

Опубликована: Сен. 28, 2022

The increased presence of xenobiotics affects living organisms and the environment at large on a global scale. Microbial degradation is effective for removal from ecosystem. In natural habitats, biofilms are formed by single or multiple populations attached to biotic/abiotic surfaces interfaces. attachment microbial cells these possible via matrix extracellular polymeric substances (EPSs). However, molecular machinery underlying development differs depending species. Biofilms act as biocatalysts degrade xenobiotic compounds, thereby removing them environment. Quorum sensing (QS) helps with biofilm formation linked in contaminated sites. To date, scant information available about biofilm-mediated toxic chemicals Therefore, we review novel insights into impact contamination remediation, regulation sites, implications large-scale compound treatment.
