Assoc. Prof. Marla Trindade

DST/NRF SARChI, Research Chair in Microbial Genomics

Director of IMBM: Institute for Microbial Biotechnology & Metagenomics

Research Projects:

My research interests lie in the microbial ecology of various environments, including thermophilic, psychrophilic, acidophilic, haloalkalophilic, marine and freshwater lakes. I am also investigating the microbial communities associated with important South African plants, including sorghum and fynbos. The understanding of microorganisms in their environment creates a natural link with biotechnology. Processes, mechanisms and products associated with microbial survival in an environment can be exploited for white, green and blue biotechnology. I therefore have several diverse interests in the application of microorganisms in biotechnology.

Who Am I?

I obtained my PhD in Microbiology in 2003 from the University of Cape Town (UCT), where I studied “Carbohydrate metabolism in Bifidobacterium”. For the following 3 years, I took up a post-doc position in Doug Rawlings’s Biomining Laboratory at the University of Stellenbosch, where I studied the molecular biology of heavy metal resistance in biomining organisms. I joined IMBM in 2006 as a post-doc, and was appointed Deputy Director in 2008 and Senior Lecturer in the Department of Biotechnology.

I co-ordinate the BTN 213 Food and Environmental Microbiology; BTN 312 Industrial Biotechnology; and BTN 706 Extremophiles courses at the undergraduate and Honours levels. I additionally run a short course (Microbial Ecology and Bioremediation) in the Biotechnology Masters at the Universidade Eduardo Mondlane, Moçambique..
