“…In addition, strain L1, a member of the unclassified Halobacteriaceae family of the phylum, Euryarchaeota also degrades benzoic acid to gentisate. Erdogmus et al [132] reported the ability of many archaeal strains belonging to Halobacterium, Haloferax, Halorubrum, and Haloarcula group to degrade p-hydroxybenzoic acid. These studies clearly demonstrate that archaea that metabolize p-hydroxybenzoic are wide spread in the environment.…”

“…Extremely halophilic archaeal strains of Haloferax, Halobacterium, and Halococcus isolated from a hypersaline coastal area of the Arabian Gulf not only degraded crude oil and n-octadecane as the carbon sources, but also grew on phenanthrene [111]. Erdogmu¸s et al [132] showed the degradation of naphthalene, phenanthrene and pyrene as the sole carbon sources by several archaeal strains including Halobacterium piscisalsi, Halorubrum ezzemoulense, Halobacterium salinarium, Haloarcula hispanica, Haloferax sp. Halorubrum sp.…”

This article is a state-of-the-art review on the aerobic degradation of petroleum components that are commonly found in the environment. Numerous microorganisms have been isolated and their phylogeny and metabolic capacity to degrade a variety of aliphatic and aromatic hydrocarbons have been demonstrated. This review focuses on recent progress on how microbes degrade hydrocarbons and heteroaromatic components of petroleum contaminants directed towards better understanding of the aerobic degradation processes and their exploitation for bioremediation. The phylogenetic diversity of the oil-degrading microbes was also discussed.

“…Recently Erdogmuş et al (16) isolated several archaea, including Halorubrum sp. and Halorubrum ezzemoulense, that grew on p-hydroxybenzoic acid, naphthalene, phenanthrene, and pyrene as the sole sources of carbon at 20% salinity.…”

“…Their work showed that benzoate induces the expression of benzoate 1,2-dioxygenase, 1,2-CAT, and 3,4-PCA, while p-hydroxybenzoate only induced the expres-sion of p-hydroxybenzoate hydroxylase (PobA). Similarly, a few hydrocarbon-degrading archaea belonging to the genera Haloferax, Haloarcula, Halobacterium, and Halorubrum have also been shown to possess catabolic enzymes similar to those from nonhalophiles (14,16,22). However, in-depth studies are needed to understand the degradation pathways and steps leading to intermediates that enter the tricarboxylic acid (TCA) cycle in organisms that withstand high salinity.…”

cArhodomonas sp. strain Seminole was isolated from a crude oil-impacted brine soil and shown to degrade benzene, toluene, phenol, 4-hydroxybenzoic acid (4-HBA), protocatechuic acid (PCA), and phenylacetic acid (PAA) as the sole sources of carbon at high salinity. Seminole is a member of the genus Arhodomonas in the class Gammaproteobacteria, sharing 96% 16S rRNA gene sequence similarity with Arhodomonas aquaeolei HA-1. Analysis of the genome predicted a number of catabolic genes for the metabolism of benzene, toluene, 4-HBA, and PAA. The predicted pathways were corroborated by identification of enzymes present in the cytosolic proteomes of cells grown on aromatic compounds using liquid chromatography-mass spectrometry. Genome analysis predicted a cluster of 19 genes necessary for the breakdown of benzene or toluene to acetyl coenzyme A (acetyl-CoA) and pyruvate. Of these, 12 enzymes were identified in the proteome of toluene-grown cells compared to lactate-grown cells. Genomic analysis predicted 11 genes required for 4-HBA degradation to form the tricarboxylic acid (TCA) cycle intermediates. Of these, proteomic analysis of 4-HBA-grown cells identified 6 key enzymes involved in the 4-HBA degradation pathway. Similarly, 15 genes needed for the degradation of PAA to the TCA cycle intermediates were predicted. Of these, 9 enzymes of the PAA degradation pathway were identified only in PAA-grown cells and not in lactate-grown cells. Overall, we were able to reconstruct catabolic steps for the breakdown of a variety of aromatic compounds in an extreme halophile, strain Seminole. Such knowledge is important for understanding the role of Arhodomonas spp. in the natural attenuation of hydrocarbon-impacted hypersaline environments.

“…The purple colour was a visual indicator of production of b-ketoadipate, a result of the ortho cleavage of the aromatic ring of sodium benzoate. Haloarchaea such as Haloferax sp., Halobacterium piscisalsi, Halobacterium salinarum and Halorubrum ezzemoulense have been reported to degrade aromatic hydrocarbons such as benzene and toluene by the ortho ring cleavage pathway of degradation [28].…”

Mangroves are unique ecosystems in the coastal tropical and subtropical regions of the Earth. The fluctuation in salinity due to tidal action results in a prolific population of adhered halophilic and halotolerant bacteria in this ecosystem. In this study, a pigment producing adhered bacterial strain Halobacillus trueperi MXM-16 was isolated from mangrove plant litter of Goa. This strain was moderately halophilic, Gram positive rod, catalase positive and capable of utilizing sodium benzoate as a source of carbon. H. trueperi MXM-16, produced a siderophore that was hydroxamate in nature. The non-diffusible yellow pigment was a carotenoid and HPLC studies revealed a peak that was indicative of astaxanthin as one of the component. Further studies on the pigment exhibited its ability to chelate iron from the chrome azurol sulphonate medium behaving as an additional mechanism for iron acquisition.
