“…The pH value was found to be 7.1 to 8.1 during the experiment recorded as compared to untreated ones which was found to be pH 7.1. These results are in agreement with those found by (Kargi and Dinner, 2000;Awasthi and Rai, 2004;Borgne et al, 2008;Abou-Elela et al, 2010;Krishnan and Neera, 2013 (Kant and Gaur, 2001). This may be due to the increase in the number of ions competing for the available binding sites in the biomass and also due to the lack of binding sites for the complication of these ions at higher concentration levels.…”

“…On the basis of the abovementioned information, it can be concluded that both the moderately halophilic bacteria and the extremely halophilic archaea have a broader catabolic versatility and capability than previously thought. A diversity of contaminating compounds is susceptible to be degraded by halotolerant and halophilic bacteria (Borgne et al, 2008).…”

Background: The wastewater is known as a mixture of one or more kinds of different water such as domestic, comprising hospitals, industrial wastewater and agricultural water. Hypersaline environments are important for both surface extension and ecological significance. As all other ecosystems, they are impacted by pollution. However, the available information on the biodegradation of organic pollutants by halophilic microorganisms in such environments are quite limited. Moreover, it is well known that 5% of industrial effluents are saline and hypersaline. The non-extremophilic microorganisms are unable to efficiently remove the organic pollutants at high salinity. Halophilic microorganisms are different metabolically and are adapted to high salinity. Therefore, these microorganisms are highly recommended to be used in bioremediation of hypersaline environments and treatment of saline effluents. Objective: This study aims to investigate the ability of different compounds in biological treatments of saline wastewater as a new technique for bio-treatment, bio-desalination and bio-removal of different heavy metals in nature circumstances. These compounds were compound I which contains mixture of different bacteria and compound II which contains mixture of different algae. These compounds were prepared under Lab condition. Results: The obtained results indicated that the removal efficiency for bio-treatment, the percentage of removal rate was found to be 79.8 and 83.5% for BOD, 82.4 and 86.3% for COD, 52.9 and 57.2 % for ammonia nitrogen and 85.8 and 98.51 % for phosphate. The high bio-removal to different heavy metals were found to reach 84.0 % and 78.50% for Al ion, 63.2 %, 85.50% for Fe ion, 85.0 % and 89.9 % for Mn ion and 78.9 % and 84.3 % for Zn ion. The results indicated that the high removal efficiency and high reduction for TDS were found to reach 39.0 % and 36.0% after 4 & 8 days in case of using compound I and compound II, respectively. The value of power equation > exponential equation for bacteria treated and algae. The correlation coefficient (R2) value of bacteria treated at 0.99, whereas for algae treated at 0. 89 for bio-desalination. Conclusion: On the basis of the obtained results it can be concluded that different biological treatments of saline wastewater with compound I and compound II were found to be effective in removal of heavy metals and reduction to TDS at 39.0 % & 36.0 % after 4 days incubation period at 40 º C and 8 days incubation at 27°-30°C for compound I and compound II respectively.

“…Members of the genus Marinobacter, for instance, are a well known and metabolically versatile group of marine facultative hydrocarbon degraders that are often found in oil contaminated saline environments (Al-Mailem et al, 2010;Le Borgne et al, 2008;Van der Kraan et al, 2009). In addition, it was shown that pure cultures of Marinobacter were able to degrade BTEX at moderately (halo)alkaliphilic conditions (Berlendis et al, 2010;Kleinsteuber et al, 2006).…”

“…Hence, it has to be removed from spent caustic solutions prior to discharge into the environment. Up till now a limited amount of literature is available on the biodegradation of mono-aromatics under haloalkaline conditions (Alva and Peyton, 2003;Le Borgne et al, 2008;Margesin and Schinner, 2001). Furthermore, the effects of benzene on biological sulfide oxidation have not been investigated.…”

“…Recent studies have shown that such environments are highly productive and have been a valuable source of novel micro-organisms (Antó n et al, 2002;Yoon et al, 2002;Li et al, 2004;Tang et al, 2010Tang et al, , 2011Wang et al, 2011;Yang et al, 2012;Tatar et al, 2013). Although advances have been slow, there is great interest in the use of halophilic or halotolerant micro-organisms to degrade organic pollutants and to produce biopolymers, biosurfactants and compatible solutes (Marhuenda-Egea & Bonete, 2002;Le Borgne et al, 2008). In this context, members of the genus Streptomyces remain a unique source of natural products, including clinically significant antibiotics, anti-metabolities and anti-tumour agents (Watve et al, 2001;Igarashi et al, 2005;Fiedler et al, 2005;Shiomi et al, 2005;Olano et al, 2009;Kim et al, 2012a).…”

The taxonomic positions of two novel actinomycetes, designated strains BNT558T and SM3501T, were established by using a polyphasic approach. The organisms had chemical and morphological features that were consistent with their classification in the genus Streptomyces . The whole-cell hydrolysates of the two strains contained ll-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H6) and MK-9(H8) for strain BNT558T and MK-9(H8) and MK-9(H6) for strain SM3501T. Major fatty acids of the strains were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The polar lipid profile of strain BNT558T contained diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, one unidentified glycolipid and one unidentified aminophospholipid, while that of strain SM3501T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine, three unidentified atypical aminolipids, one unidentified aminolipid and two unidentified glycolipids. The G+C contents of the genomic DNA were 70.2 and 69.6 mol% for strains BNT558T and SM3501T, respectively. 16S rRNA gene sequence data supported the classification of the isolates in the genus Streptomyces and showed that they formed two distinct branches within the genus. Based on almost-complete 16S rRNA gene sequences, strain BNT558T was related most closely to Streptomyces albiaxialis NRRL B-24327T and strain SM3501T was related most closely to Streptomyces cacaoi subsp. cacaoi NBRC 12748T. DNA–DNA relatedness between each of the isolates and its closest phylogenetic neighbours showed that they belonged to distinct species. The two isolates were readily distinguished from one another and from the type strains of the other species classified in the genus Streptomyces based on a combination of phenotypic and genotypic properties. Based on the genotypic and phenotypic evidence, strains BNT558T and SM3501T belong to two novel species in the genus Streptomyces , for which the names Streptomyces iconiensis sp. nov. (type strain BNT558T = KCTC 29198T = DSM 42109T) and Streptomyces smyrnaeus sp. nov. (type strain SM3501T = KCTC 29214T = DSM 42105T) are proposed, respectively.
