Science and technology are "empowered", and Zhao'an marine industry has entered a new track

Can marine algae be used as bacterial media in healthcare facilities?

"We extract the active ingredients from the two red algae species of cauliflower and dragon's whiskers to make a high-purity biochemical agar, which is an essential raw material for the food industry, chemical industry and medical research, and is also commonly used as a bacterial culture medium." On the 15th, Zeng Huanjian, general manager of Fujian Heidelberg Biotechnology Co., Ltd., told reporters that since the company settled in Zhao'an Jindu Industrial Zone in 2017, it has built a high-purity agar production line with an annual production capacity of 150 tons of medium, and 10 scientific and technological achievements have been transformed into product technology, and the annual output value can be 45 million yuan.

The optimal temperature for biochemical agar into a plate Dish is 35 to 40 °C, but the agar usually begins to solidify at 39 °C and needs to be heated to 95 °C to melt. How to reduce the freezing point of biochemical agar has become a scientific and technological bottleneck that Heidelberg urgently needs to break through.

"After 14 months of scientific and technological research, the freezing point of marine biological high-purity agar produced by the company has been controlled at 30~36 °C, and the large-scale mass production of high-purity agar medium has been realized." Zeng Huanjian said that the upgraded biochemical agar can replace similar high-priced imported products, is continuing to supply to Qingdao, Beijing and other media factories, sales in 2021 exceeded 20 million yuan, an increase of 91.35% year-on-year, last December, the company was also listed as a technology-based regulations on the enterprise.

Fujian Dabei Nong Aquatic Products Technology Co., Ltd., located in Zhao'an County, launched a new fermentation functional material last year, which was well received by the market. Mr. Chen, a farmer in Haicheng Town, Longhai District, Zhangzhou, said that in his 40 shrimp ponds, all of them were sprinkled with the fermentation liquid of Dabeinong, and in the case of changeable weather after winter, his shrimp seedlings not only grew well, but also the drainage rate was very low, and the shrimp's anti-stress resistance was strong.

"Used with traditional feed, it adds probiotic preparations, plant extracts, astaxanthin and other ingredients on the basis of the original ingredients, which can not only improve the digestive function of aquatic animals, but also promote feed conversion efficiency, stabilize water quality, and is the best booster for the breeding process." Song Junying, deputy director of research and development of Fujian Dabei Agricultural Aquatic Products Technology Co., Ltd., said.

In 2021, Fujian Dabeinong Aquatic Products Technology Co., Ltd. added 9 new invention patents, of which the output value of fermentation functional material series products was as high as 15 million yuan, an increase of 50% year-on-year. It is understood that Fujian Dabeinong Aquatic Products Technology Co., Ltd. is a high-tech enterprise mainly engaged in the production of efficient marine microbial preparations and supporting products, and has a provincial key laboratory - Fujian Provincial Aquatic Functional Feed and Aquaculture Environment Regulation Laboratory. For the first time, the company created a three-level mixed liquid deep fermentation process of 10 strains of aquatic microorganisms, successfully broke through and created a total comprehensive technical system such as aquaculture source pollution reduction, process pollution reduction, aquaculture discharge water treatment and water recycling.

In recent years, Zhao'an County has comprehensively promoted the deep integration of scientific and technological innovation and marine economy, and in 2021, the output value of marine economic industry will exceed 1.6 million yuan, an increase of 20% year-on-year. 4 enterprises in the county were rated as the 2021 Provincial Science and Technology Small Giant Enterprises, 3 enterprises were rated as the Provincial Science and Technology Small and Medium-sized Enterprises in 2021; and the technical transformation projects of the aquatic products deep processing production line of 5 enterprises were included in the provincial and municipal key technological transformation project database, with a total investment of about 202 million yuan.
