Isolation Of Magnetotactic Bacteria Used In Wastewater Treatment From Lakes Aquatic Environment

Abstract

This research presents detection and isolation of magnetotactic bacteria (MTB) from two lakes habitats, utilizing the established methodologies to improve isolation rates, with on sampling, enrichment and purification methods. Environmental samples from two lakes in Algeria were collected and cultured. Microscopy observation identified movement of MTB and growth occurred consistently in purifying medium at the oxic-anoxic transition zone which indicated MTB activity. Obtained results of transmission electron microscopy (TEM) confirm the presence of magnetotactic bacteria in the two lakes, which are being identified for biotechnological applications.
