Development of inocula for animal cell processes. The properties of a successful inoculum of an animal cell fermentation are the same as those for a microbial fermentation—a pure, metabolically active culture that has retained its product-forming ability and is available in a sufficient volume. There is increasing interest in the use of beneficial microorganisms as alternatives to chemical pesticides and synthetic fertilisers in agricultural production. Application of beneficial microorganisms to seeds is an efficient mechanism for placement of microbial inocula into soil where they will b … BACKGROUND. Lactic acid bacteria inocula have been developed over the years to improve the aerobic stability of silages.
