Biotechnology: From the laboratory to the marketplace

Abstract

From the laboratory to the marketplace Dunaliella is a green, salt-loving micro-alga that revels in hyper-saline water, harsh sunlight and extreme heat. It is also the Ingredient-X in cost-effective biological massproduction of high-value β-carotene - an anti-oxidant that is converted to Vitamin A by the liver. Environmental biotechnologist Peter Rose and his team came up with a process that uses polluted wastewater as a growth medium for this important harvest, reports Catherine Knox. Their initial laboratory work has been scaled up for evaluation as a commercial production process.
