The trusted source of accurate, proven methodology for analyzing natural waters, water supplies, and wastewaters. The 23rd edition of Standard Methods for the Examination of Water and Wastewater® contains over 400 laboratory methods for the analysis of • Dissolved Solids • Metals • Free and Total Chlorine • Odor, Taste, and Flavor Profile Analysis • Disinfection By-products • Radionuclides • Total Organic Carbon • Total and Fecal Coliform Laboratories worldwide rely on this comprehensive reference as the trusted source of accurate, proven methodology for analysis of water, water supplies, and wastewater. It is the essential resource for water analysis professionals. The methods in the 23rd edition (as in previous editions) are believed to be the best available, generally accepted procedures for analyzing water, wastewater, and related materials.

Out of the 23 isolates three most potent isolates named BDCC-TUSA-8, BDCC-TUSA-12 and BDCC-TUSA-18 were selected for their efficient COD removal and active growth. The three isolates were tested separately in Bushnell-Haas (BH) media for their capabilities to degrade n-Hexadecane, phenol and phenanthrene, representing the major types of hydrocarbon pollutants. The results strongly indicated that all three isolates showed multiple degradation potentials with remarkably fast reaction rates. Before being recommended for future work, the three isolates were fully characterized and identified employing culture-dependent techniques such as API 20E, API 20NE and API 50CHB, and further confirmed by partial 16S rRNA gene sequencing and phylogenetic analysis as Pantoea agglomerans, Acinetobacter lwoffii and Bacillus thuringiensis respectively. The obtained potent strains provide valuable candidates if assemblages of mixed fewer strains with overall broad and complementary enzymatic capacities are to be considered in order to bring the rate and extent of petroleum biodegradation further as a cost-effective process.
