  • Patent number: 6433025
    Abstract: Astaxanthin is a potent antioxidant, over 500 times more powerful than Vitamin E and 10 times stronger than other carotenoids such as zeaxanthin, lutein, canthaxanthin and beta-carotene. Astaxanthin has also been shown to enhance and modulate the immune system. Disclosed is a method and treatment for retarding and preventing sunburns. The method comprises administering a source of astaxanthin in a therapeutically effective amount to prevent and retard sunburns.

  • Patent number: 6344214
    Abstract: Astaxanthin is a potent antioxidant, over 500 times more powerful than Vitamin E and 10 times stronger than other carotenoids such as zeaxanthin, lutein, canthaxanthin and beta-carotene. Astaxanthin has also been shown to enhance and modulate the immune system and diminish the damaging effects of UVA sunlight. Disclosed is a method for retarding and ameliorating fever blisters (cold sores) and canker sores. The method comprises administering a source of astaxanthin in a therapeutically effective amount to prevent, retard and ameliorate fever blisters and canker sores. The astaxanthin may be administered orally, topically, or in a combination of oral and topical dosage.

  • Patent number: 5659977
    Abstract: An integrated plant including a microalgae production plant for growing, harvesting and drying algae and a fossil fuel-motor-generator plant producing electrical energy. A fossil fuel engine produces hot exhaust gas from which sensible heat dries the algae. The drying may be direct from the exhaust gas or may be indirect with the hot exhaust gas exchanging sensible heat with a recirculating stream of inert gas. Carbon dioxide from the exhaust gas is recovered for use as a nutrient in the microalgae production plant. Electrical energy from the generator is used to drive motors and/or produce artificial illumination and/or drive pumps, motors and controls in the microalgae production plant.

  • Patent number: 5276977
    Abstract: This is a method and apparatus for drying microalgae/microalgal products which have been harvested and strained of excess water by a spray drying process. The method comprises, obtaining drying gas from a burner in which metered input air for combustion is mixed with fuel at or before a dryer gas heating burner and which does not require oxygen in the drying gas that is heated; using the drying gas to dry the microalgae/microalgal products in a spray dryer; separating dryed microalgae/microalgal products from moist drying gas in a cyclone; scrubbing and dehumidifying the moist drying gas; recycling the scrubbed and dehumidified drying gas to the dryer gas heating burner; and, venting a portion of the drying gas equivalent in volume to combustion gases generated in the burner. Scrubbing and dehumidifying is accomplished by spraying the moist drying gas with sea water at a temperature below 60.degree. F.
