Efficient and energy-saving method for culturing seawater chlorella

Resumen de: CN121674216A

The invention discloses an efficient and energy-saving method for culturing seawater chlorella, and belongs to the technical field of microalgae culture, an annular bioreactor with a built-in light source is adopted, seawater is added, then disinfection is performed, and then a continuous culture method or a semi-continuous culture method is performed, the semi-continuous culture comprises a pre-culture stage and a semi-continuous culture stage, the continuous culture method comprises a pre-culture stage and a continuous culture stage, the seawater chlorella is continuously and stably cultured for not less than 30 days, and the daily productivity is not less than 0.194 g/L/day. The method has the advantages of simplicity in operation, low cost, high seawater chlorella growth rate and the like. According to the method, the annular photobioreactor is utilized, efficient and energy-saving production of the seawater chlorella is realized by optimizing a culture mode and illumination conditions, and the biomass stability in an experimental system is maintained to be not shorter than 30 days.

Application and method of bacillus pumilus in joint production of squalene and unsaturated fatty acid and obtained microbial oil

Resumen de: CN121674494A

The invention belongs to the technical field of microbial fermentation, and particularly relates to application and method of bacillus pumilus in joint production of squalene and unsaturated fatty acid and obtained microbial oil. A method for joint production of squalene and unsaturated fatty acid comprises the following steps: S1, respectively carrying out amplification culture on schizochytrium limacinum HS08 and bacillus pumilus to obtain a schizochytrium limacinum amplification culture and a bacillus amplification culture; wherein the preservation number of the schizochytrium limacinum HS08 is CGMCC (China General Microbiological Culture Collection Center) No.40902, and the preservation number of the bacillus pumilus is CGMCC No.1.1166; s2, one of the schizochytrium limacinum enlarged culture and the bacillus enlarged culture obtained in S1 is inoculated into a co-culture medium for fermentation; the bacillus pumilus and the schizochytrium limacinum HS08 are subjected to combined fermentation, so that the yield of microbial oil produced by microalgae fermentation is greatly increased, particularly the content of squalene and EPA is also greatly increased, the method is suitable for industrial large-scale production, and the production cost of squalene and EPA is reduced.
