| titleOfInvention | Improvements in or relating to the production of micro-organisms |
| abstract | A micro-organism, particularly yeast, capable of growing on a feedstock consisting wholly or in part of straight chain hydrocarbons, is cultivated in the presence of the feedstock, an aqueous nutrient medium and a gas-containing free oxygen, the operation being carried out in a batchwise manner whereby over a period of the growth the rate of growth of the micro-organism increases progressively with time and during or after a period of rapid growth the micro-organism is recovered, and at a time when the rate of growth is high (preferably the maximum) a part of the total quantity of the micro-organism is withdrawn and employed as an inoculum for initiating the growth of a further batch of the micro-organism. The feedstock preferably includes a straight chain hydrocarbon having at least 10 carbon atoms in the molecule, or comprises a petroleum fraction containing 3-45% by weight of straight chain hydrocarbons. Yeasts mentioned are Candida lipolytica, Candida pulcherrima, Candida utilis, Candida tropicalis, Torulopsis collisculosa, Hansenula anomala, Oidium lactis, Neurospora sitophila and Mycoderma cancoillote. Micro-organisms such as Penicillium expansum, Pseudomonos aeruginosa and Nocardia opaca may also be cultivated. Examples are directed to the cultivation of Candida lipolytica and Hansenula anomala on heavy petroleum gas oil.ALSO:A micro-organism, particularly yeast, capable of growing on a feedstock consisting wholly or in part of straight chain hydrocarbons, is cultivated in the presence of the feedstock, an aqueous nutrient medium and a gas containing free oxygen, the operation being carried out in a batchwise manner whereby over a period of the growth the rate of growth of the micro-organism increases progressively with time and during or after a period of rapid growth the micro-organism is recovered, and at a time when the rate of growth is high (preferably the maximum) a part of the total quantity of the micro-organism is withdrawn and employed as an inoculum for initiating the growth of a further batch of the micro-organism.

Yeasts mentioned are Candida lipolytica, Candida pulcherrima, Candida utilis, Candida tropicalis, Torulopsis collisculosa, Mansenula anomala, Oidium lactis, Neurospora sitophila and Mycoderma cancoillote. Micro-organisms such as Penicillium expansum, pseudomas aeruginosa and Nocardia opaca may also be cultivated. Examples are directed to the cultivation of Candida lipolytica and Hannsenula anomala on heavy petroleum gas oil. Yeast withdrawn during the exponential growth phase exhibited no lag and accelerating phases when inoculated into fresh medium. |
