Biomass from microalgae

Biomass from microalgae: the potential of domestication towards sustainable biofactories SUMMARY: Microalgae could potentially be a renewable source of energy for people. Unfortunately, there are many issues right now with growing enough algae and keeping the process affordable (aka: it’s too expensive to grow and use algae commercially). The article is divided up into several… Continue reading Biomass from microalgae

Rotifers Eating Bacteria to Clean Water

Foam-forming bacteria in activated sludge effectively reduced by rotifers in laboratory- and real-scale wastewater treatment plant experiments SUMMARY: This article looks at using rotifers as a way to control a specific type of filamentous bacteria in wastewater treatment plants. Overgrowth of this bacteria leads to foam and inefficient break down of waste by other microorganisms.… Continue reading Rotifers Eating Bacteria to Clean Water
