Molecular Detection, Isolation, and Physiological Characterization of Functionally Dominant Phenol-Degrading Bacteria in Activated Sludge
One of the dominant strains, R3, which contained a novel type of LmPH (P3), was closely related toValivorax paradoxus, and the result of a kinetic analysis of its phenol-oxygenating activity suggested that this strain was the principal phenol digester in the activated sludge.
Oleibacter marinus gen. nov., sp. nov., a bacterium that degrades petroleum aliphatic hydrocarbons in a tropical marine environment.
Three Gram-negative, motile, mesophilic, aerobic, rod-shaped bacterial strains isolate from Indonesian seawater exhibited high n-alkane-degrading activity, which indicated that the strains were important degraders of petroleum aliphatic hydrocarbons in tropical marine environments.
Alkane‐degrading properties of Dietzia sp. H0B, a key player in the Prestige oil spill biodegradation (NW Spain)
Aims:  Investigation of the alkane‐degrading properties of Dietzia sp. H0B, one of the isolated Corynebacterineae strains that became dominant after the Prestige oil spill.
Oceanobacter-related bacteria are important for the degradation of petroleum aliphatic hydrocarbons in the tropical marine environment.
Oceanobacter-related bacteria could be major degraders of petroleum n-alkanes spilt in the tropical sea after an accidental oil spill and continue to dominate in the environment after biostimulation.
PhcS Represses Gratuitous Expression of Phenol-Metabolizing Enzymes in Comamonas testosteroni R5
Results show that the PhcS protein repressed the gratuitous expression of phenol-metabolizing enzymes in the absence of the genuine substrate and that strain R5 acted by an unknown mechanism in which thePhcS-mediated repression was overcome in the presence of the pathway substrate.
An Outbreak of Nonflocculating Catabolic Populations Caused the Breakdown of a Phenol-Digesting Activated-Sludge Process
It is suggested that an outbreak of nonflocculating catabolic populations caused the breakdown of the activated-sludge process and the usefulness of gyrB-targeted fine population analyses in microbial ecology is demonstrated.
Enrichment of carotenoids in flaxseed (Linum usitatissimum) by metabolic engineering with introduction of bacterial phytoene synthase gene crtB.
The metabolic engineering of flax plants to increase carotenoid amount in seeds suggests that the flux of phytoene synthesis from geranylgeranyl diphosphate was first promoted by the expressed crtB gene product (CrtB), and then phy toene was consecutively decomposed to the downstream metabolites alpha-carotene, beta-carotsene, and lutein, as catalyzed by endogenous carOTenoid biosynthetic enzymes in seeds.
Characterization of a high-affinity phenol hydroxylase from Comamonas testosteroni R5 by gene cloning, and expression in Pseudomonas aeruginosa PAO1c
A phylogenetic analysis shows the phenol hydroxylase from strain R5 to be more closely related to toluene/benzene-2-monooxygenase (Tb2m) from Pseudomonas sp.
