A method of autotrophic cultivation of algae includes cultivating algae in the presence of cultivation media and at least one growth nutrient to produce an algal biomass; and harvesting the algal biomass by separating the algal biomass from the cultivation media and the at least one growth nutrient. The algal biomass comprises at least 35% fatty acid lipid content and at least 30% protein content on an ash-free dry weight basis

Provided a method for promoting growth of bacteria of the genus Bifidobacterium. The method for promoting growth of bacteria of the genus Bifidobacterium includes subjecting a milk culture medium containing one or more selected from the group consisting of cysteine, cystine, and a salt thereof to heat treatment and then culturing bacteria of the genus Bifidobacterium in the milk culture medium.

Microbial starter cultures. More specifically, a method for preparing a microbial culture such as a lactic acid bacteria (LAB) starter culture wherein at least one microbial strain such as a lactic acid bacteria and at least one inactivated yeast strain is inoculated in a culture medium.

Disclosed herein is a method for promoting growth of a probiotic microorganism. The method includes cultivating the probiotic microorganism in a growth medium containing a fermented culture of lactic acid bacterial strains that include Lactobacillus salivarius subsp. salicinius AP-32 deposited at the China Center for Type Culture Collection (CCTCC) under CCTCC M 2011127, Lactobacillus plantarum LPL28 deposited at the China General Microbiological Culture Collection Center (CGMCC) under CGMCC 17954, Lactobacillus acidophilus TYCA06 deposited at the CGMCC under CGMCC 15210, and Bifidobacterium longum subsp. infantis BLI-02 deposited at the CGMCC under CGMCC 15212.

The present invention relates to a method for promoting growth of gas-fermented microorganisms, comprising the following steps: S1. ultrasonically blending a surfactant and a culture medium, then adding a fluorine-containing alkyl compound to a mixture, and ultrasonically processing the mixture to obtain a perfluorocarbon nanoemulsion; S2. inoculating a bacterial suspension into the perfluorocarbon nanoemulsion, and introducing simultaneously a mixed gas to obtain a precursor; S3. cultivating the precursor in a shaker, wherein the precursor has a diameter of bubbles of 2.0-4.2 mm, and the bubbles have the total volume of less than 40 ml. Under these conditions, the microorganisms have a high utilization rate of the gas, can grow and metabolize more quickly, and can obtain bacteria and products more quickly. Compared with a traditional culture system, addition of a mass transfer material can promote gas mass transfer. Therefore, the gas consumption is small, and the cost is low.
