The present invention relates generally to the field of food compositions comprising algae. In particular, the present invention relates to a food composition comprising algae which are heat treated to reduce unwanted off-flavors. The algae may be algae from the Chlorella genus. For example, the algae may be Chlorella vulgaris. One embodiment of the present invention relates to a method to reduce the off-taste of an algae containing composition comprising a heat treatment, wherein the heat treatment comprises a primary heat treatment at a temperature in the range of about 130-160° C. and a secondary heat treatment at a temperature in the range of about 90-150° C.

Some embodiments are directed to a system for harvesting biomass, usable to manufacture biofuel, from discrete biomass receptacles in which the biomass has been cultivated. The system can include multiple harvesters disposed at least in part vertically above the receptacles and configured to simultaneously harvest the biomass from the receptacles. Each of the harvesters can include: multiple harvesting baskets configured to be lowered from above the receptacles and into each of the receptacles; multiple sensors disposed to sense growth conditions within the harvesting baskets; and a controller configured to communicate with each sensor of the multiple sensors, and based on data received from the sensors, configured to control harvesting patterns of each harvester to enhance biomass material growth within the receptacles.

The present invention provides a process of cultivating microalgae and a joint method of same jointed with denitration. During the microalgae cultivation, EM bacteria is added into the microalgae suspension. In the nutrient stream for cultivating microalgae, at least one of the nitrogen source, phosphorus source and carbon source is provided in the form of a nutrient salt. During the cultivation, the pH of the microalgae suspension is adjusted with nitric acid and/or nitrous acid. The joint method includes (1) a step of cultivating microalgae; (2) a separation step of separating a microalgae suspension obtained from step (1) into a wet microalgae (microalgae biomass) and a residual cultivation solution; and (3) a NOx absorbing/immobilizing step of denitrating an industrial waste gas with the residual cultivation solution obtained from step (2). The nutrient stream absorbed with NOx obtained from step (3) is used to provide nitrogen source to the microalgae cultivation of step (1).

Disclosed is a non-toxic omega-3 rich extract and non-toxic miscella and a method of producing same. The method may include obtaining an aqueous microalgae slurry comprising at least 65% water; mixing the aqueous microalgae slurry with ethanol for a predetermined duration; separating the aqueous microalgae slurry-ethanol mixture to liquids and miscella; and evaporating the water and the ethanol from the liquid to receive a liquid extract. In some embodiments, the miscella contains organic material and ash at an amount below 15 dry weight %.

[Problem] The purpose of the present invention is to provide a method for collecting seawater that contains plankton and generating DHMBA (dba), which is an antioxidant, from the plankton contained in the seawater. [Solution] The present invention is characterized in that: collected seawater containing plankton is filtered using a filter, the cell contents are removed from the plankton remaining on the filter, the removed cell contents are subsequently heated, and 3,5-dihydroxy-4-methoxybenzyl alcohol is produced from the heated product; and the plankton are assumed to be diatoms.

Disclosed are techniques and systems for producing microbials having anaplerotic oils that are rich in odd-chain fatty acids, and other beneficial components, at higher concentrations than those present in other natural dietary sources of OCFA, at lower cost, and higher production yield. Further, disclosed are examples of incorporation of these higher concentration OCFA products into food for human and non-human animal consumption.

A modified cyanobacterium in which an organic channel protein which improves protein permeability of an outer wall is expressed.

Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desaturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, or can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.

The invention pertains to a method for synthesizing a product of interest by culturing a microalgal cell obtained from a subterranean habitat for producing the product of interest. The microalgal cell obtained from a subterranean habitat can be cultured in the dark, in light, in low nutrition, or nutrient rich conditions for at least a portion of production cycle. A combination of these conditions can be used to specifically manipulate a microalgal cell culture to produce a product of interest. The product of interest can be a water-soluble carotenoid, for example, a water-soluble carotenoid produced by culturing an algae belonging to the genus Haematococcus or a capsular exopolysaccharide produced by culturing an algae belonging to the genus Parachlorella. Compositions containing the water-soluble carotenoid, for example, as sunscreen and compositions containing the exopolysaccharide, for example, as moisturizing cream are also described.

Disclosed herein are methods and compositions for implementing a photosynthetic protein secretion platform.
