Isolation of magnet-responsive bacteria from the tropical marine environment of Singapore

Magnetotactic Bacteria (MTB) are a group of unique, diverse and motile prokaryotes that can be found in most aquatic environment. Through the synthesis of magnetosomes, MTB are able to migrate along the geomagnetic and artificial magnetic field lines. Up to today, many isolation works have been carr...
