The Aquatic Biotechnology Laboratory specializes in the cultivation of microalgal and seaweed cultures to study their industrial and commercial applications. From its establishment in 2009, ABL has grown from a single workbench laboratory to a laboratory sporting its own facilities including a plant growth chamber, ultralow freezer and liquid nitrogen tank.
Biofuel from Green microalgae
Studies are being conducted on the effect of modifying growth conditions to enhance lipid production. Nutrient starvation (e.g. decrease in nitrogen, phosphate and silica) is known to promote lipid accumulation within cells. The laboratory also aims to find genes involved in the oil-producing mechanisms of algae for genetic manipulation.
Production of Red Seaweed
Seaweed tissue culture studies aim to establish improved callus induction protocols for micropropagation and to develop cryopreservation methods to preserve strains with the best genetic makeup.
The laboratory also aims to study the production of carageenan, a high value polysaccharide obtained from Eucheumatoids.
Another area of interest is the production of bacteriocins from seaweed-associated bacteria. Bacteriocins are proteins that inhibit the growth of closely related bacterial strains and may be useful as antibiotics.
