Algae research. Researcher in a laboratory that genetically-engineers algae to produce oil and remove metal pollutants from the environment. She is holding a petri dish that contains an algae culture. Oil-producing algae absorb carbon dioxide gas and convert it into oil. The pollution- control algae have a slime coating which traps metal ions, allowing bacteria to convert them into recoverable metal. The petri dish contains a nutrient medium which allows the algae to grow.
