A method of improving the rheological properties of a flour dough and the quality of the finished product made from such a dough, including adding an effective amount of an oxido-reductase capable of oxidizing maltose, in particular a hexose oxidase, e.g. isolated from an algal species such as Iridophycus flaccidum, Chondrus crispus or Euthora cristata and a dough improving composition containing the oxidore-ductase.

A method of isolating nutraceuticals products from algae is provided. A method of isolating carotenoids and omega-3 rich oil from algae includes dewatering substantially intact algal cells to make an algal biomass and adding a first ethanol fraction to the algal biomass. The method also includes separating a first substantially solid biomass fraction from a first substantially liquid fraction comprising proteins and combining the first substantially solid biomass fraction with a second ethanol fraction. The method further includes separating a second substantially solid biomass fraction from a second substantially liquid fraction comprising polar lipids and combining the second substantially solid biomass fraction with a third ethanol solvent fraction. The method also includes separating a third substantially solid biomass fraction from a third substantially liquid fraction comprising neutral lipids, wherein the third substantially solid biomass fraction comprises carbohydrates and separating the neutral lipids into carotenoids and omega-3 rich oil.

The invention relates to a kind of microbic reagent curing breed aquatics water by multi-bacteria. It can degrade and transform organic contamination of water, prohibite the growth of harmful algae and pathogeny bacteria, and promote propagation of beneficial creature, forming good entironment for growth of aquatic animal. Environment select breed and abduction select breed are adopted in this invention, spontaneous aberration and directional breed are combined, fermentated technology of original compound breed and domestication are used to make many bacteria of improved water mixed and matched each other. What' s more, growth factor and special carrier are added for promoting the growth of microbe, guaranteeing the efficiency of improvement. This product can take the place of antibiotic in feed, producing organic farm products which are green, safe and antibiotic-free.

The invention provides a device for separating a first entity and a second entity by flowing them downwardly in an inclined settling chamber. Each entity has its own outlet located at approximately the lowest end of the inclined settling chamber. The device may be used in industrial fields such as pharmaceutics, biologics, and biofuels, for the purposes of large-scale growth and separation of algae biomass, bacteria and yeast cultures; algae metabolite production; and cell separation, among others. The invention exhibits technical merits such as effective particle separation or concentration capacity, robust structure, easy operation, cost-effective manufacturability, disposability, and high productivity in e.g. perfusion photobioreactor systems.

A vegetable alga and microbe photosynthetic reaction system and method for the same is used for vegetable algae and microbe cultivation liquid and algae seeds infused herein to circularly conduct photosynthesis and discharge oxygen; the vegetable alga and microbe photosynthetic reaction system comprises a photosynthetic reaction unit, a pressure liquid infusion unit, and an oxygen discharge and regulation unit; the photosynthetic reaction unit is a light permeable pipeline; the oxygen discharge and regulation unit is assembled with an oxygen discharge can, a liquid collection can, and a regulation can for facilitating production and assembly, and many oxygen discharge points so that oxygen formed in the cultivation liquid can be quickly evaporated.

The invention belongs to the field of aquaculture or feed, relates to a aquaculture feed, and especially relates to an alga immunopotentiation compound feed for litopenaeus vannamei. The invention at first provides an immunity strengthening agent for litopenaeus vannamei feed, and the agent is obtained through enzymatic hydrolysis and fermentation of an alga composite. The alga composite is composed of following components in parts by dried weight: 40 to 50 parts of asparagus, 15 to 25 parts of enteromorpha, 10 to 20 parts of ulva lactuca, 5 to 15 parts of laver and 5 to 15 parts of undaria pinnatifida. The invention further prepares a compound feed for litopenaeus vannamei by utilizing the immunity strengthening agent. The alga immunity strengthening agent contains algae polysaccharide, which has the effect of strengthening animal immunity, acrylic acid, terpenes, brominated phenolic and some sulfocompounds, which have the antiseptic effect, and sulphated polysaccharide, which has the antivirus effect. The litopenaeus vannameis fed on the alga immunopotentiation compound feed have a strong anti-stress performance, the body's immunity ability is improved, survival rate is high and culture benefit is remarkable.

The invention discloses a milk beverage formula containing algae. The milk beverage contains one or more of chlorella, spirulina and haematococcaceae, also can be one or more of the algae extracts, wherein adding amount is 0.1%-4%; the algae milk beverage is milk-containing beverage which is prepared by taking milk or a milk product as a material, adding water and one or more of chlorella, spirulina and haematococcaceae, and modulating one or more of sugar and (or) a sweetening agent, an acid agent (or not added with the acid agent), fruit juice, planting fat end, instant tea powder or tea extracts, coffee, plant extract (liquid), and the like; according to the algae milk beverage, the chlorella, spirulina and haematococcaceae are added into the sugar and (or) the sweetening agent, the acid agent, the milk material, the plant extract (liquid), a feed additive, and the like by a burdening step, and prepared into a finished product by processes of dissolving, mixing, cooling, adding acid (or not adding acid), homogenizing, filling, sterilizing, cooling, labeling, inspecting, and the like, and also can be prepared into a finished product by adopting a sterile packaging way, directly sterilizing after homogenizing, thermally filling, cooling, labeling, inspecting, and the like. The product prepared by the technology disclosed by the invention has characteristics of being mellow in mouthfeel, rich in nutrition, healthy and green.

Provided herein are exemplary methods for production of biomass with a cyanobacterial isolate having auto-flocculation properties. One exemplary method includes isolating a cyanobacterial strain having a 16S ribosomal RNA sequence corresponding to SEQ. ID. NO. 1 herein, inoculating an algae cultivation system with the cyanobacterial strain, growing the cyanobacterial strain, and harvesting the biomass produced by the cyanobacterial strain. According to a further method, the harvesting of the biomass comprises ceasing agitation of the algae cultivation system, and pooling a slurry of the biomass produced by the cyanobacterial strain. In a further method, the harvesting of the biomass may comprise ceasing agitation within the algae cultivation system and / or allowing the biomass produced by the cyanobacterial strain to settle to near or at a bottom of the algae cultivation system. Also provided herein are exemplary cyanobacterial strains having flocculation properties for production of a biomass.

The present invention relates to a method of detecting phycocyanin algae or bacteria in water from reflected light, and also includes devices for the measurement, calculation and transmission of data relating to that method.
