However, the shelf-life of their algae is only for three weeks and need to be refrigerated if needed to be preserved for more time. The advantages of having it fresh are that it has virtually no taste, so you can mix it with anything.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Roof tops are excellent venues to grow algae because the high temperatures and constant sunlight helps it to grow.\u00a0 A recent study the Oilgae team revealed that a company \u2013 EnerGaia, based out of Bangkok, grows Spirulina on roof tops in specialized photobioreactors.
