  • Patent number: 12139698
    Abstract: An Axial Dispersion Bioreactor (ADBR) is designed for the photoautotrophic, mixotrophic or heterotrophic growth and production of microalgae and other microorganisms (bacteria, fungi, etc.) as well as cell cultures of plants, animals, insects and others. The ADBR is equipped with a plate having a plurality of holes that moves longitudinally or axially within the bioreactor to effect superior hydrodynamic and mixing patterns. The ADBR has the advantages of providing a low-shear culture environment, superior liquid mixing, and efficient gas mass transfer.

  • Publication number: 20240049664
    Abstract: The Intelligent Aeroponic Microgravity & Earth Nutrient Delivery (I-AMEND) System is configured to enable the productive growth of crops on the Moon, Mars, and beyond as well as in space stations in low-Earth orbit, such as the International Space Station (ISS), and also on Earth. Principal components of the I-AMEND system may include an aeroponic chamber, a liquid nutrient emitter for emission of a liquid into the aeroponic chamber, and an air emitter for emission of a gust of air into the aeroponic system. The emitters may be positioned upstream or downstream of a plant port of the aeroponic chamber so as to direct the liquid onto or off of a surface of the plant root.

  • Patent number: 11274290
    Abstract: Methods of enhancing biomass and secondary metabolite accumulation of microalgal species are described herein. A cell culture of the microalgal species were elicited using a combination of techniques for a period of time. Experimental studies compared biomass dry weight production, chlorophyll dry weight content and astaxanthin dry weight content between controls and elicitation treatments. The present invention demonstrated that combined elicitation is an effective method for improving cell biomass growth and astaxanthin production.

  • Patent number: 8725220
    Abstract: A power saving method for a mobile device in a wireless communication system is disclosed. The power saving method comprises obtaining a first parameter according to a first signal transmitted between the mobile device and a first network; estimating a first power consumption of the mobile device in the first network according to the first parameter and a first radio access technology (RAT) employed in the first network; determining whether the first network is suitable according to at least a comparison of the first power consumption with a second power consumption of the mobile device in a second network, wherein the second network employs a second RAT different from the first RAT; and switching to a the second network when the first network is not suitable.
