title: Acclimated biomass that degrades Sulfonated Naphthalene Formaldehyde Condensate.
abstract: 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 pressure osmometry, spectroscopy UV-Visible and Chemical Oxygen Demand (COD). The degradation of SNFC by acclimated bacterial consortium was determined by monitoring the decrease of absorbance and of COD at wavelength 288 nm. We were able to deduce that biodegradation of SNFC involves two steps: cleavage of CH2 bridges and the degradation of the aromatic nuclei. The bacteria species community that was able to degrade SNFC consisted of aerobic Gram-negative rods belonging to the Pseudomonadaceae family. The strains were identified as Bukholderia cepacia, Brevundimonas vesicularis, Pseudomonas stutzeri, Ralostonia picketti, Shewanella putrefaciens, Sphingomonas paucimobilis and Agrobacterium radiobacter.
