| 摘要 |
The present invention refers to a biological formulation for complementing an animal feed, which comprises: dry cells of Cupriavidus necator or Alcaligenes latus bacteria, containing at minimum 40% of PHB and B vitamins, tyrosine, glutamic acid, phosphates and iron, which formulation may further contain the endogenous PHB depolymerase enzyme. The process for obtaining the formulation comprises the steps of: (a) producing, by aerobic fermentation, from 32 to 34° C., in a mineral and aqueous fermentative medium containing sucrose, glucose or other sugary streams derived from sugar production, cells of Cupriavidus necator or Alcaligenes latus bacteria containing at minimum 40% of PHB and B vitamins, tyrosine, glutamic acid, phosphates and iron; (b) inactivating the cells, thermally, at a temperature from 65 to 90° C. for 15 minutes; and (c) drying the bacteria cells obtained in the previous step. |
