Claim:
A sterile microorganism growth substrate comprising: (a) a sterilized nutrient composition, wherein said composition is a biomass generated from bacterial cells by autolysis, optionally followed by ultrafiltration and evaporation, wherein said bacterial cells comprise Methylococcus capsulatus (Bath) (strain NCIMB 41526), Ralstonia sp. DB3 (strain NCIMB 41527), Aneurinibacillus sp. DB4 (strain NCIMB 41528) and Brevibacillus agri DB5 (strain NCIMB 41525), and wherein said bacterial cells are at least 50% by weight Methylococcus capsulatus (Bath) (strain NCIMB 41526) relative to the total bacterial weight; (b) sterile glucose; and (c) optionally a sterile diluent.
