Oil spills threaten coastlines where biological processes supply essential ecosystem services. Therefore, it is crucial to understand how oil influences the microbial communities in sediments that play key roles functioning. Ecosystems such as are characterized by intensive bioturbation due burrowing macrofauna may modify metabolisms. It thus consider when determining impact of on communities. In this study, an experimental laboratory device maintaining pristine collected mudflat microcosms...
Marinobacter hydrocarbonoclasticus SP17 forms biofilms specifically at the interface between water and hydrophobic organic compounds (HOCs) that are used as carbon energy sources. Biofilm formation HOC-water has been recognized a strategy to overcome low availability of these nearly water-insoluble substrates. Here, we present genome sequence SP17, which could provide further insights into mechanisms enhancement HOCs assimilation through biofilm formation.
Microbial communities inhabiting hypersaline wetlands, well adapted to the environmental fluctuations due flooding and desiccation events, play a key role in biogeochemical cycles, ensuring ecosystem service. To better understand functioning, we studied soil microbial of Salineta wetland (NE Spain) dry wet seasons three different landscape stations representing situations characteristic ephemeral saline lakes: S1 usually submerged, S2 intermittently flooded, S3 with halophytes. community...
A set of 11 expression vectors was constructed, each them harbouring a cloning cassette under the control promoter. Some these enable foreign proteins in cytoplasm, while others include synthetic sequence coding for very efficient secretion signal sequence. Other features are an fl origin replication (in plus or minus orientation) and promoterup mutation that enhances already high level from vectors. With such versatile vector family, cloning, sequencing sitedirected mutagenesis can be...
Integrons, genetic elements known to be involved in the adaptation of pathogenic bacteria, were first discovered clinical setting. However, they are ancient structures found various environments. When integrons have a low diversity, with three integrases and gene cassettes essentially encoding antibiotic resistance, natural environments, show greater both integrases. Although large number from environmental samples been identified, integrase diversity remains poorly documented, has not yet...
Deciphering the ecology of marine obligate hydrocarbonoclastic bacteria (MOHCB) is crucial importance for understanding their success in occupying distinct niches hydrocarbon-contaminated environments after oil spills. In coastal sediments, MOHCB are particularly subjected to extreme fluctuating conditions due redox oscillations several times a day as result mechanical (tide, waves and currents) biological (bioturbation) reworking sediment. The adaptation was investigated by an experimental...
ABSTRACT The first gene cassettes of integrons are involved in the last adaptation response to changing conditions and also most expressed. We propose a rapid method for selection clones carrying an integron cassette that is useful finding adaptive genes environmental metagenomic libraries.
Abandoned brownfields represent a challenge for their recovery. To apply sustainable remediation technologies, such as bioremediation or phytoremediation, indigenous microorganisms are essential agents since they adapted to the ecology of soil. Better understanding microbial communities inhabiting those soils, identification that drive detoxification process and recognising needs interactions will significantly improve outcome remediation. With this in mind we have carried out detailed...
Environmental integrons are ubiquitous in natural microbial communities, but they mostly uncharacterized and their role remains elusive. Thus far, research has been hindered by methodological limitations. Here, we successfully used an innovative approach combining CRISPR-Cas9 enrichment with long-read nanopore sequencing to target, a complex community, putative adaptive environmental integron, InOPS, unravel its complete structure genetic context. A contig of 20 kb was recovered containing...
