Bioemulsifiers

The present invention relates to compositions containing bacteria capable of degrading hydrocarbons, such as petroleum or petroleum products and methods for their use.

Non-polluting compositions to degrade hydrocarbons and microorganisms

The present invention relates to polymeric dispersing agents for finely divided materials, particularly minerals, which are fermentation products of bacteria. The invention relates to bacterial strains producing such dispersants and to a process for the production of the dispersants by fermentation of such bacteria. The invention further relates to compositions containing effective quantities of such polymeric fermentation products in order to be effective dispersants for minerals.

Bacterial process for the production of dispersants

The present invention relates to a live vaccine for the vaccination of poultry and mammals against a variety of gram negative pathogens belonging to Enterobacteriaceae, comprising a bacterial deletion mutant derived from a non-pathogenic strain of E. coli; to a process for obtaining bacterial mutant strain for use in a live vaccine according to claim 1, which comprises exposing a non-pathogenic strain of E. coli to a mutation inducing agent and selecting strains devoid of O-antigens, and cultivating same to obtain the bacteria for use in such live vaccine; to the novel mutant strain E. coli LR-2, and to a process for immunizing poultry and mammals against Enterobacteriaceae which comprises applying to the avian or to the mammal an effective dose of such a vaccine by oral route or as aerosol.
