Spirulina growing as a food colorant

Tom Coultate, author of Food: the Chemistry of its Components, writes for Britain’s Royal Society of Chemistry that the move from synthetic to “natural” food colorants has not been as simple as might be imagined. For example. the anthocyanins – abundant in fruit – work well in the mildly acidic environments of soft drinks…

India-based Phycospectrum Environmental Research Centre (PERC) has installed a 550 KL treatment facility at Pasupati Acrylon, an acrylic fibre manufacturing industry in India. PERC has installed similar facilities based on microalgal technology in a number of industries in India and Colombia…

Algae + pig manure = feed + biogas

Algae + pig manure = feed + biogas

Sean Murphy writes for ABC News Australia that pig effluent could be used to grow algae or seaweed that is fed back to pigs as part of a closed-loop system for intensive piggeries. Pig manure can also help reduce use of costly fertilizer in the process. Researchers at Murdoch University’s Algae Research and…
