The invention relates to an artificial seedling raising and cultivating method of edible sargassum.naozhouense. According to the method, a cement pit is taken as a seedling raising field, and adopted seawater is filtered and disinfected; a nylon seedling curtain is taken as an adherence for artificial spatfall, seed sargassum.naozhouense in a propagation period is selected for seedling picking and is turned manually every 4-5 hours during the seedling picking process; during the cultivating period, the seawater is used to flush mixed algaes and sludges on the seedling curtain at regular intervals, and the seawater in the pit is changed every 3 days and is added with nutrient salt; the seedlings are clamped and put in a sea area to be cultivated when growing to about 5 centimeters long; the cultivation yield is 1700kg / Km of fresh weight each seedling rope; and the seedlings are cultivated in diurnal tide sea areas with shallow water layer and higher water temperature (the maximum of which is 33.7 DEG C), thus being beneficial to the maturity of archegoniophore, and the maturity of the archegoniophore is earlier than that of the naturally growing algae by at least one month. The artificial seedling raising and cultivating method can be applied to artificial seedling raising and cultivating of the sargassum.naozhouense in a large scale, and is also an effective method for protecting and reproducing the natural resources of the sargassum.naozhouense, and the cultivated product is used for realizing commercial purposes of food, medicine, fertilizer, feed, seaweed industry and the like.

The present invention provides unique technology, systems and methods of cultivating different types of seaweeds, including, but not limited to, Porphyra (Nori), Laminaria, Undaria, Eucheuma, Gracillaria, Ulva, Sargassum, Codium, Cladophora, Ascophyllum, Palmaria, Furcellaria, Fucus or Enteromorpha, in land-based seawater ponds having a climatically suitable and nutrient controlled environment.

A method for the production of biofuels from the open ocean comprises the steps: testing the currents to determine that a biomass remains in a zone suitable for harvesting; harvesting a portion of the biomass; and processing a portion of the harvested biomass to produce useful components of biofuels. An improved method of production of a biofuel comprises the additional steps of testing the ocean surface waters to determine any nutrients that are missing, and applying a fertilizer with any missing nutrients. The currents should be such that the biomass created stays in the ocean waters suitable for harvest rather than washed up on shores, or dispersed to other areas of the ocean. Suitable currents include ocean gyres such as the Sargasso Sea. Suitable biomass includes seaweeds that float in the open ocean and aggregate together in floating patches, such as the Sargassum weed in the Sargasso Sea.

The invention belongs to the technical field of processing of algae and specifically relates to a method for preparing alginic acid and alginate by taking fresh sargassum as a raw material. The method for preparing alginic acid and alginate by taking fresh sargassum as a raw material comprises the following steps of: cleaning, color fixing, digestion, liquid-slag separation, acidification, obtainment of the alginic acid and reaction with a salt to obtain the alginate. The method disclosed by the invention has the beneficial effects that compared with the method for preparing alginic acid and salt thereof by taking traditional dried sargassum as a raw material, by adopting the method for preparing alginic acid and alginate by taking fresh sargassum as a raw material, disclosed by the invention, the problem of degradation of colloid due to the reduction in stability of the dried sargassum is avoided, the colloid component in the sargassum is retained to the greatest extent, and the product quality of the alginic acid and the salt thereof which are produced subsequently is further ensured.

The invention discloses a directional synthesis method of a biomass activated carbon-based electrode material containing micropore-mesopore channels and an application thereof. Sargassum is used as araw material; NH3.H2O is introduced to carry out pretreatment on the biomass; chemical bonds between cellulose / hemicellulose / lignin are broken; the material chemical activity is enhanced, meanwhile, part of lignin is removed; the cellulose / hemicellulose ratio is increased, hard carbon removal is realized, an activating agent permeates into a carbon fiber structure more efficiently, and pore etching is reinforced by virtue of defects formed after lignin removal, so that formation of a three-dimensional porous channel is promoted, and the response capability of the material to high current is remarkably improved. The supercapacitor electrode material is prepared from the marine biomass, the preparation process is simple, the cost is low, the pollution is small, the material has relatively high mass specific capacitance and excellent cycling stability and rate capability, and the material is a process which has a potential application value, turns waste into wealth and is beneficial to realization of large-scale industrial synthesis.

A process for extracting edible fibres from sargassum includes such steps as washing, cutting, immersing, extracting by sodium carbonate, filter, neutralizing, filtrate, adding calcium chloride to obtain gel, bleaching with sodium hypochlorite, activating, dewatering, baking, pulverizing to obtain soluble edible fibres, treating the filtered dregs with acid or alkali, bleaching, dewatering, baking, pulverizing to obtain insoluble edible fibres, and proportionally mixing soluble with insoluble edible fibres (4:1).
