摘要:
The present invention relates to a consortium of Nitrosomonas eutropha and Nitrobacter winogradskyi, which is more effective at removing ammonia and nitrite than the commonly used consortium of Nitrosomonas europea and Nitrobacter winogradskyi, particularly in aquaculture such as shrimp ponds. Supplementation of the consortium in aquaculture such as shrimp ponds may lead to an increase in total yield, an increase in size, a decrease in Food Conversion Ratio (less food required per kg of shrimp obtained), and an increase in total per pond sales.
摘要:
A method for obtaining differentiated cells from stem cells in vitro, comprising the steps of: (a) growing stem cells in a culture medium adhered to a microcarrier or a bead, confined within a medium permeable barrier or entrapped; (b) transferring the cells in step (a) from one culture medium to another; (c) optionally repeating step (b) as required; and (d) obtaining the differentiated cells.

PROBLEM TO BE SOLVED: To provide oils and fats-assimilating microorganisms capable of decomposing waste oil containing the oils and fats discharged from a business establishment such as a restaurant, etc., and waste oil, oils and fats components and organic waste materials in discharged water, and a method for treating discharged water and a method for deodorizing a bad smell by using the same. SOLUTION: The waste oil such as the oils and fats in the discharged water is decomposed by utilizing the oils and fats-assimilating microorganisms. As the oils and fats-assimilating microorganisms decomposing the waste oil such as the oils and fats, new oils and fats-assimilating microorganisms belonging to the genus Sphingomonas and/or Nocardia, and also a mixture of a strain belonging to the genus Nocardia with a strain belonging to the genus Sphingomonas and/or Microbacterium and/or Bacillus can be used. The method for decomposing the waste oil such as the oils and fats and the method for deodorizing the bad smell by using such the microorganisms or a mixture of them are also provided.
