The anaerobic biodegradation of naphthalene, an aromatic hydrocarbon in tar and petroleum, has been repeatedly observed environments but scarcely pure cultures. To further explore the relationships physiology naphthalene-degrading microorganisms, sulfate-reducing bacteria (SRB) were enriched from a Mediterranean sediment with added naphthalene. Two strains (NaphS3, NaphS6) oval cells isolated which showed naphthalene-dependent sulfate reduction. According to 16S rRNA gene sequences, both...

Summary Among the dominant deltaproteobacterial sulfate‐reducing bacteria ( SRB ), members of genus D esulfobacula are not only present in (hydrocarbon‐rich) marine sediments, but occur also frequently anoxic water bodies encountered upwelling areas. Here, we 5.2 Mbp genome toluolica Tol2 , which is first an aromatic compound‐degrading, . The has apparently been shaped by viral attacks (e.g. CRISPRs ) and its high plasticity reflected 163 detected genes related to transposases integrases, a...

Abstract Amplicon sequencing using next‐generation technology ( bTEFAP ® ) has been utilized in describing the diversity of Dead Sea microbiota. The investigated area is a well‐known salt lake western part Jordan found lowest geographical location world (more than 420 m below sea level) and characterized by extreme salinity (approximately, 34%) addition to other conditions (low pH , unique ionic composition different from water). DNA was extracted water. A total 314,310 small subunit RNA SSU...

The evolution of drug resistant strains microbial pathogens provides an urgent need to develop novel therapeutical regimes with resistance-combating capacity. In this study, the phytochemical composition and antibacterial activities essential oils from Cleome droserifolia trinervia growing in Jordan desert were investigated. Hydro-distilled analyzed using GC–MS evaluated for activity vitro against a selection Gram-positive Gram-negative bacteria by agar-well diffusion micro-dilution methods....

Detection of new Actinobacteria is significant to discover antibiotics because development connected the characterization novel bacterial taxa. This study has focused on identification and isolation antibiotic-producing from sediment water Ma'in thermal springs (48-59°C) situated in center area Jordan.Samples were transferred glucose yeast malt agar medium cultivated, isolated identified according scanning electron microscopy 16S rRNA gene analysis. Antibacterial activities isolates then...

Abstract A culture‐independent approach was utilized in this study to reveal the microbial diversity Jordanian hot springs represented by Ma'in and Afra springs. Water samples from were collected June 2015. The situ temperature of water range 38–59°C pH 7.4–8.4. metagenome extracted analyzed using next generation technology ( bTEFAP ® ). total 314,310 sequences parsed 288,452 then clustered. predominated bacteria (>84%) relative abundance archaea each sample <1%. Eukaryotic...

Ma'in hot springs are known as sites of balneotherapy. However, little is about their microbiology and chemistry. In this study, we aim at evaluating the antimicrobial activity hot-springs water (MHSW), studying its microbiology, determining physicochemical properties including heavy metals content. Therefore, samples were collected from tested for using agar diffusion method. Water was then cultivated on nutrient to isolate identify dominant bacteria by chemical molecular methods. The...

This study was performed to assess the antioxidant and antibacterial properties of methanolic extracts derived from aerial parts four Jordanian medicinal plants (Artemisia sieberi, Peganum harmala, Rosmarinus officinalis (Green-Flowered) Sarcopterium spinosium). The possible relationship between these biological total phenolic concentrations were also be determined. capacity assessed by ABTS method Folin-Ciocalteu method, respectively. amount extract required scavenge 50% (IC50) measured....

Recently, four heterocyclic compounds containing 1,2,4-triazole (designated as Y2, Y3, Y30, and Y32) were synthesized by our lab. Previous data showed that nucleus posses a wide range of pharmacological activities such antioxidant, antiviral, antitumor antibacterial activities. Currently, the need for triazole derivatives with broad spectrum activity are in rise. Therefore, these encouraged us to test newly their against three types bacteria: standard, environmental medical bacteria. Both...

Toluene can enter the environment due to various industrial activities. exposure may cause serious health risks human and other living organisms. Thus, removal of toluene from is exceptionally important in toluene-contaminated habitats. The aim present study was isolate characterize toluene-utilizing bacteria contaminated soil surrounding car body repair painting workshops Irbid city, Jordan. Therefore, polluted samples (10 g) were transferred flasks containing 99 ml Stanier's medium...

The global continued decline in coral reefs is intensifying the need to understand response of corals local environmental stressors. Coral-associated bacterial communities have been suggested a swift pollutants. This study aims determine variation associated with mucus two species, Pocillopora damicornis (Linnaeus, 1758) and Stylophora pistillata (Esper, 1792), coral-surrounding seawater from three areas exposed contamination at Jordanian coast Gulf Aqaba (Red Sea), also explores...

A C T Xylene is frequently released into the environment from biomass.As a consequence of this, its bioaccumulation can cause adverse health effects in humans.The purpose this study was to screen for aerobic xylene-degrading bacteria gasoline contaminated soil sites located around gas stations city Al-Mafraq, Jordan.The some physicochemical factors were examined.The 10 g sample transferred Stanier's mineral medium supplemented with 1% m-xylene and incubated at 30°C 72 h.At least 4 degrading...

Background: Selenium (Se) is a non-metal element, occurring in varying degrees the environment and it has been found to be component of several enzymes.Different selenium compounds have associated with carcinogenicity, toxicity, modification metal toxicity prevention cancer.Organoselenium had substantially greater bioavailability less than that inorganic selenium.From chemical point view, Se resembles sulfur (S) many its properties, thus, S may considered isosteric.The ability synthetic...

Background and Objective: Raw meats from animal carcasses are most frequently contaminated with bacteria during the slaughtering dressing process. Therefore, this study aimed to determine bacterial quality of raw meat lamb, goat beef immediately after at butcher shops in Al-Mafraq city-Jordan.Materials Methods: A total 243 samples were aseptically cut hand, leg back three locations, designated as site-C (the central part city), site-N north side city) site-S south city).
