| titleOfInvention | Process for converting methane into proteinaceous material |
| abstract | 1420751 Cultivating methane-utilizing bacteria BRITISH PETROLEUM CO Ltd 26 March 1973 [28 March 1972] 14397/7.2 Heading C6F In the continuous cultivation of a methane utilizing micro-organism e.g. Methylococcus capsulatus in a broth comprising an aqueous nutrient medium containing nutrient salts, in the presence of methane and a gas containing free oxygen (air), a first nitrogen source added to the broth is a utilizable compound which is soluble in the broth to give ammonium ions (liquid or gaseous ammonia, ammonium hydroxide or ammonium chloride) and a second nitrogen source added to the broth is of combined nitrogen in a form which does not give ammonium ions and which is less readily utilizable than the first nitrogen source (nitric acid and/or sodium or potassium nitrate), and the quantities added are such as to give an ammonium ion concentration of less than 2.0 milligrams per litre of broth and an excess of combined nitrogen over that utilized (if any). The ammonium source may provide 95-99% of the total nitrogen requirement for microbial growth. The amount of nitric acid/nitrate added may be sufficient to supply 2-12% of the total requirements. |
