Abstract: The present invention relates to an integrated method for processing algal biomass comprising a marine algal strain or a freshwater (non-marine) algal strain or a plurality of marine algal strains or a plurality of freshwater (non-marine) algal strains or any combination thereof or other carbonaceous feedstocks like biosolids or any combination of algae/algae mixtures and carbonaceous feedstocks to produce biofuel. The method includes subjecting the algae/algal mixture to hydrothermal liquefaction/co-liquefaction using sub-critical water to produce a biocrude. The biocrude is pretreated using a renewable biocatalyst to remove impurities which include Nitrogen (N), Sulfur (S), Oxygen (O) and salts and the pretreated biocrude is mixed with heteroatoms a petrocrude to form a biocrude-petrocrude blend. The biocrude-petrocrude blend is distilled and the distillate fractions are treated using the renewable biocatalyst to remove impurities and finally hydrotreated to produce fractions biofuels.

Abstract: A system and method for culturing algae are presented. The system and method utilize a fog of growth medium that is delivered to an algal mat generator along with a stream of CO2 to promote growth of algal cells contained in the generator.

Abstract: The present disclosure relates to biological optimization systems for enhancing photosynthetic efficiency and methods of use.

Abstract: Biological optimization systems for enhancing photosynthetic efficiency and methods of use. Specifically, methods for enhancing photosynthetic efficiency including applying pulsed light to a photosynthetic organism, using a chlorophyll fluorescence feedback control system to determine one or more photosynthetic efficiency parameters, and adjusting one or more of the photosynthetic efficiency parameters to drive the photosynthesis by the delivery of an amount of light to optimize light absorption of the photosynthetic organism while providing enough dark time between light pulses to prevent oversaturation of the chlorophyll reaction centers are disclosed.

Abstract: Embodiments of the present disclosure provide for biochar impregnated with microbes, methods of making biochar impregnated with microbes, methods of using biochar impregnated with microbes, methods of using biochar to produce gas, reactors using biochar and/or biochar impregnated with microbes, methods of using the reactors, and the like.

Abstract: Embodiments of the present disclosure provide for novel strategies to harvest algal lipids using mollusks which after feeding algae from the growth medium can convert algal lipids into their biomass or excrete lipids in their pseudofeces which makes algae harvesting energy efficient and cost effective. The bioconverter, filter-feeding mollusks and their pseudofeces can be harvested and converted to biocrude using an advanced thermochemical liquefaction technology. Methods, systems, and materials are disclosed for the harvest and isolation of algal lipids from the mollusks, molluscan feces and molluscan pseudofeces.

Abstract: The disclosure encompasses, among other aspects, mixed algal populations able to survive and proliferate on culture media that have a high proportion of an industry wastewater. In particular, at least one strain of an alga in the algal population proliferates mixotrophically. Embodiments further encompass methods of cultivating mixed populations of freshwater and marine alga comprising a plurality of genera and species to provide a biomass from which may be extracted lipids, or converted into biodiesel by such procedures as pyrolysis. Lipid material extracted from the algae may be converted to biodiesel or other organic products. Native algal strains were isolated from industrial and in particular agricultural wastewater inoculated with mixed populations derived from environments exposed to such wastewater. Both fresh water and marine algae showed good growth in wastewaters. About 65% of the algal oil obtained from the algal consortium cultured on an industry wastewater could be converted into biodiesel.

Abstract: The present disclosure provides methods of enhancing the biofuel potential of an algal culture, the ability of an algal culture to provide a biofuel such as a lipid or to be processed to a biofuel, the method comprising: contacting an algal culture with a composition selected to enhance the biofuel potential of an algal culture; and allowing the algal culture to incubate to the point where the potential of the algal culture to provide a biofuel product or be processed to a biofuel product is enhanced compared to when the algal culture is not in contact with the composition. The selected algal species can be a species of a genus selected from the group consisting of: Gloeocystis, Limnothrix, Scenedesmus, Chlorococcum, Chlorella, Anabaena, Chlamydomonas, Botryococcus, Cricosphaera, Spirulina, Nannochloris, Dunaliella, Phaeodactylum, Pleurochrysis, Tetraselmis, or any combination thereof, one suitable species being Chlorella sorokiniana.

Abstract: The disclosure encompasses, among other aspects, mixed algal populations able to survive and proliferate on culture media that have a high proportion of carpet industry wastewater. Embodiments further encompass methods of cultivating mixed populations of freshwater and marine alga comprising a plurality of genera and species to provide a biomass from which may be extracted lipids, or converted into biodiesel by such procedures as pyrolysis. Lipid material extracted from the algae may be converted to biodiesel or other organic products. A combined stream of carpet industry untreated wastewater with 10-15% sewage was found to be a good growth medium for cultivation of microalgae and biodiesel production. Native algal strains were isolated from carpet wastewater inoculated with mixed populations derived from environments exposed to such wastewater. Both fresh water and marine algae showed good growth in wastewaters.
