The Pseudomonas putida АК5 that was isolated from the slime pit of a Nizhnekamsk oil chemical factory can metabolize naphthalene via salicylate and gentisate. Catabolic genes are localized on non-conjugative IncP-7 plasmid pAK5 about 115 kb in size. "classical" nah-1 operon novel sgp-operon (salicylate-gentisate pathway) both involved degradation by P. АК5, first described for Pseudomonas. includes six open reading frames (ORFs) (sgpAIKGHB). four ORFs code entire 5-hydroxylase –...
Biodegradation of phenol is an effective method for removing this toxicant from contaminated sites. Phenol a toxic compound living cells, so many bacteria degrade in relatively low concentrations, up to 0.75 g L−1. The Rhodococcus opacus strain 1CP destructor wide range pollutants. In the absence carbon source medium, cells R. easily form cyst-like resting (CLC). purpose work was evaluate viability during long-term storage and efficiency process destruction by germinating after dormancy....
Pollution of the environment by crude oil and products (represented various types compounds, mainly aliphatic, mono- polyaromatic hydrocarbons) poses a global problem. The strain Pseudomonas veronii 7-41 can grow on medium-chain n-alkanes (C8-C12) polycyclic aromatic hydrocarbons such as naphthalene. We performed genetic analysis physiological/biochemical characterization cultivated in mineral medium with decane, naphthalene or mixture hydrocarbons. genes responsible for degradation alkanes...
Alkane-oxidizing bacteria play a crucial role in the global carbon cycle. Rhodococcus species are well-known hydrocarbon degraders, distinguished by harboring of multiple homologs AlkB family alkane monooxygenases. Although different types rhodococcal AlkBs have been described, overall picture their diversity remains unclear, leaving gaps current classification. We conducted phylogenetic analysis all identified (sensu lato) and examined genomic context corresponding genes. The sequence...
The impact of geographical factors, functional zoning, and biotope type on the diversity microbial communities chemical components in dust urban ecosystems was studied. Comprehensive analyses bacterial fungal communities, polycyclic aromatic hydrocarbons (PAHs), metals road leaf three zones Murmansk Moscow with contrasting anthropogenic load were conducted. We found that structure affected zoning city, type, components. Fungal instead impacted only by type. Our findings revealed mostly PAHs...
The phylloplane is an integrated part of green infrastructure which interacts with plant health. Taxonomic characterization the aim to link it ecosystem functioning under anthropogenic pressure not sufficient because only active microorganisms drive biochemical processes. Activity remains largely overlooked. We aimed study interactions among biological characteristics phylloplane: taxonomic diversity, functional diversity and activity, pollution grade. Leaves Betula pendula were sampled in...
We performed a comparative study of the total bacterial communities and cultivable polycyclic aromatic hydrocarbons (PAH)-degrading bacteria in different functional zones Moscow Murmansk that were formed under influence PAH composition road leaf dust. The PAHs determined by high-performance liquid chromatography (HPLC); communities’ diversity was assessed metabarcoding. degraders isolated their direct plating on medium with PAHs. quantity declined dust from traffic to recreational zone. For...
Strains of the genus Delftia are poorly studied microorganisms. In this work, complete genome naphthalene-degrading tsuruhatensis strain ULwDis3 isolated from seawater Gulf Finland Baltic Sea was assembled. For first time, genes encoding naphthalene cleavage pathways via salicylate and gentisate were identified in a Delftia. The part one operon (nag genes). Three open reading frames (ORFs) found D. that encode 1.2-dioxygenase. One ORFs is nag operon. physiological biochemical characteristics...
The complete genome of the naphthalene- and n-alkane-degrading strain Pseudomonas sp. OVF7 was collected analyzed. Clusters genes encoding enzymes for degradation naphthalene n-alkanes are localized on chromosome. Based Average Nucleotide Identity digital DNA-DNA Hybridization compared with type strains group fluorescent pseudomonads, bacterium studied probably belongs to a new species. Using light, fluorescent, scanning electron microscopy, ability form biofilms different architectures when...
For the first time, a mycological analysis of outdoor urban environment (air, leaves, sealed surfaces) was carried in cities subarctic (Murmansk) and temperate (Moscow) climatic zones. The chemical composition dust deposited on leaves dominant tree species taken as an indicator air quality. Assessment complex impact factors (climate zone, type substrate, anthropogenic load) quantitative qualitative parameters mycobiome performed. Compared to Moscow, Murmansk characterized by increased number...
