Abstract: 

The legal responsibility of the destination and treatment of waste and industrial effluents is due to the generator, the appropriate treatment and installation for disposal have become a problem, since industrial production is increasingly generating complex waste. Residues with concentrations of salt and organic matter from the chemical, agri-food, leather and oil industries negatively affect conventional treatments, inhibiting enzymatic activity of microorganisms. The search for viable technologies for the treatment of this waste, such halophilic bacteria are those that need a saline concentration in the medium to develop and can be an alternative for the treatment of wastes and effluents with high levels of salt. The objective of this study was to evaluate the growth potential of isolated bacteria from dry salted cod (Gadus sp.) in salinity, considering future applications in the treatment of saline residues and effluents. The samples were divided for microbial growth according to different temperature, oxygenation and pH conditions to obtain isolates submitted to biochemical tests. From the 4 fermented isolates, resistance of the different saline concentrations was observed, classifying them as at least moderate halophilic bacteria, allowing their use in future studies as indicators in treatments with saline residues and effluents.
