Abstract
1307041 Improved fermentations involving charcoal MOBIL OIL CORP 21 April 1971 [27 July 1970 2 Sept 1970] 10361/71 Heading C6F In a fermentation process in which a microorganism, a source of carbon for the growth of the micro-organism, mineral nutrients and water constituting a fermentation broth are retained in a fermentation vessel for a given residence time, at least a portion of the fermentation broth (including the micro-organism) is contacted during the residence time with charcoal. The fermentation broth may be passed through a bed of charcoal. Alternatively, the charcoal may be confined within a foraminous container which is maintained in the body of broth. The particles of charcoal should be sufficiently large to avoid filtration of the micro-organism cells e.g. between 4 and 8 mesh in the U. S. Standard Sieve Series, and not smaller than 10 mesh. At least 1 gram (even 10 grams or more) of charcoal is employed for each litre of fermentation broth every 24 hours. Many species of micro-organism are particularly mentioned. Carbon sources include specified hydrocarbons, oxygenated hydrocarbons, carbohydrates and cellulosic materials e.g. garbage or waste products from paper manufacture. Air is injected into the broth (where required at gauge pressure in the range of 6 to 225 mm. Hg. Injection rates, dilution ratios and superficial velocities for the air are mentioned. An example relates to a continuous cultivation of Pichia yeast on n-hexadecane. Enhanced cell productivities, conversion efficiencies and protein contents were achieved when the fermentation broth was circulated through a bed of wood charcoal.
