Method for treating marine aquaculture wastewater by co-cultivation of filamentous lyngbya and bait microalgae chlorella

NºPublicación: CN110282747A 27/09/2019

Solicitante:

UNIV NINGBO

Resumen de: CN110282747A

The invention provides a method for treating aquaculture wastewater by co-cultivation of filamentous algae and microalgae. The method is characterized in that the filamentous algae and the microalgae are co-cultivated at an appropriate ratio to treat the aquaculture wastewater, wherein the filamentous algae is sacchariferous lyngbya, and the microalgae is bait microalgae. According to the method, based on the disadvantage that harvesting is difficult after the aquaculture wastewater is treated by microalgae cultivation, the filamentous algae and green algae which are high in added value and are easy to harvest are coupled for co-cultivation to treat the aquaculture wastewater; the method is expected to reduce the harvesting cost after wastewater treatment and improve the economy of resource utilization of microalage wastewater treatment.

Water quality improvement agent for fancy carp and preparation and use methods thereof

NºPublicación: CN110282753A 27/09/2019

Solicitante:

TIANJIN XIANDAI CHENHUI TECH GROUP CO LTD

Resumen de: CN110282753A

The invention provides a water quality improvement agent for fancy carp and preparation and use methods thereof. A formula of the water quality improvement agent comprises the following components in parts by weight: compound probiotic dry powder, spirulina powder, limestone powder, zeolite powder, glucose and decavitamins. The water quality improvement agent provided by the invention is rich in various probiotic groups,the quantity of effective microbial communities in a water body and aquatic organisms can be increased, the occurence of various bacterial diseases, fungal diseases and viral diseases is effectively prevented, mass propagation of algae, such as cyanobacteria, dinoflagellate and euglena, which are not conducive to water quality optimization and fancy carp growth is prevented, metabolic waste of fancy carp in ponds is effectively decomposed and absorbed, ammonia nitrogen and nitrite contents in the water body are reduced, and dissolved oxygen is increased; the content of carbonate in the limestone powder is relatively high, so that the buffer capacity of aquaculture water can be increased; the water body is kept slightly alkaline; the fancy carp growth is better facilitated. According to the water quality improvement agent, the spirulina powder is specially added, and can be used as a supplementary ingredient of feed, the immunity level of the fancy carp can be enhanced through long-term use, and the effect of improving body colors can also be achieved.

DUNALIELLA MUTANT AND METHOD FOR PRODUCING PIGMENT BY USING SAME

Nº publicación: US2019290712A1 26/09/2019

Solicitante:

UNIV HANYANG IND UNIV COOP FOUND [KR]

CN_110225968_A

Resumen de: US2019290712A1

A novel alga mutant having improved pigment productivity is provided. The mutant can be used to produce carotenoid-based pigments, particularly, xanthophyll by using a small amount of energy, and thus can effectively produce pigment on an industrial level. In addition, the mutant can be used as a source for foods, health functional foods, and medications which contain a pigment. Further, when account is taken of the physiological characteristics of the euryhaline microalgae Dunaliella and the geological characteristics of Korean, the three sides of which are in contact with the sea, sea-water can be used as a culture medium, with the expectation of reducing the cost and leading to the development of related industries.
