, started searching for the biological production of citric acid. First they tried by letting random micro-organisms ferment
Fermentation (biochemistry)
Fermentation is the process of extracting energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound. In contrast, respiration is where electrons are donated to an exogenous electron acceptor, such as oxygen,...

 after which they achieved a productivity which allowed for industrial exploitation. This led to the foundation of the Belgian-Italian company La Citrique Belge in 1929. In 1947, the basic substrate sugar was changed with the cheaper by-product molasses
Molasses
Molasses is a viscous by-product of the processing of sugar cane, grapes or sugar beets into sugar. The word molasses comes from the Portuguese word melaço, which ultimately comes from mel, the Latin word for "honey". The quality of molasses depends on the maturity of the sugar cane or sugar beet,...
