Abstract:

A total of thirteen bacterial isolates were isolated from Eastern, Western harbors’ of Alexandria and Lake Mariout. The isolates were screened for various biotechnological applications such as the ability to produce antibacterial compounds and extracellular enzymes (including, protease, lipase, amylase and cellulase), as well as their ability to degrade crude oil and chemical dyes and to solubilize phosphate. Results revealed that 9 isolates were protease producers, 6 of them showed lipase activity and none of them produced cellulase or amylase. Four of the isolated bacteria exhibited antibacterial activity against Staphylococcus aureus ATCC 25923 and two bacterial isolates against Escherichia coli ATCC 8739 .None of them showed the ability to solubilize tri-calcium phosphate or to decolorize and degraded the tested dyes saffranin and crystal violet. Three isolates showed the potential ability to degrade crude oil. The study has overall concluded that marine bacteria could serve as potential bio resources for many biotechnological applications.
