A mutant of pseudomonas, a strain yzh, and a process for producing 851yzh nutrient solution by application of the strain

摘要

This invention relates to a mutant pseudomonas identified as strain YZH and the use of the strain by means of a fermentation process to produce a single cell protein nutrient solution from plant protein . The resulting nutrient solution is suitable as food for animals and human , and has salutory effects on animals and human such as reducing bleeding of the gastric mucosa , stimulating and improving hemogenesis and inhibiting cancer cell growth and traversing the cancer cell into its normal cell. The main characteristics of the strain YZH are that it is a rod in light yellow color , has at lease one flagellum , has the ability to reduce nitrate and to liquidize gelatine , is not able to produce water soluble pigment , and to form poly- beta -hydroxy butyrate and in particular , has a Y fragment in its DNA which is detectable by means of a specific Y fragment DNA probe.
