Abstract
There is described a process for the culture of microorganisms in a medium comprising a hydrophobic material containing microorganisms by the use of nutrient substances in aqueous solution micro-emulsified in a liquid immiscible with water. As the source of nitrogen, compounds soluble in water are used, such as urea or ammonium nitrate, sulphate or phosphate, and, as the source of phosphorus, compounds soluble in water are used. The medium should also contain a directly-assimilable source of carbon. Application of this process to the culture of microorganisms, allowing operations to be carried out which comprise the degrading of hydrocarbons covering an area of water or ground; an application of particular interest for operations for combatting oil pollution of the sea by biological degradation.
