The ability of Vibrio alginolyticus strains isolated from a bathing and fishing area (Khenis, Centre of Tunisia) to adhere to both biotic and abiotic surfaces was evaluated in the present work. The biochemical, physiological and enzymatic activities of all strains was also investigated. Three morphotypes of V. alginolyticus were obtained on Congo red agar(More)
Several studies in recent years have provided evidence that Pseudomonas aeruginosa has a non-clonal population structure punctuated by highly successful epidemic clones or clonal complexes. The role of recombination in the diversification of P. aeruginosa clones has been suggested, but not yet demonstrated using multi-locus sequence typing (MLST). Isolates(More)
Synthetic dyes are widely used in the textile, cosmetic, printing, drug, and food processing industries. Triphenylmethane dyes belong to the most important group of synthetic dyes. They are generally considered as the xenobiotic compounds, which are very recalcitrant to biodegradation.Bacillus sp., was isolated from the treatment plant effluent of a textile(More)
A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial(More)
A number of aerobic species were isolated from textile industry activated sludge wastewater. The bacterial consortium was acclimated during seven days before testing its capacity of Sulfonated Naphthalene-Formaldehyde Condensate (SNFC) recalcitrant compound degradation. SNFC's degradation was evaluated by using different techniques including: vapour(More)
In this study, Gram negative bacterium,Sphingomonas paucimobilis, was used to test its ability to decolourise two triphenylmethane dyes: malachite green (MG) and crystal violet (CV) in mineral salts medium (MSM). Decolourisation was examined with dye concentrations (2.5, 5, 15, 25, 30 and 50 mg/l), glucose (0, 1.4, 2.8, 4.2, 5.6 and 7 mM) and yeast extract(More)
The purpose of the present study was to explore the potential behavioural changes of Pseudomonas aeruginosa following growth in different aquatic environmental conditions. To achieve this, P. aeruginosa was cultured in various water microcosms for 12 months under fixed (pH, nutrients and temperature) factors. P. aeruginosa responses to these conditions were(More)
