Citric acid obtained through the microbial fermentation is considered synthetic while that of present in fruits is referred to as natural (Ranya et al., 1999; Karklins et al., 2001). It is responsible for the tart taste of various fruits e.g., lemons, limes, oranges, pineapples, pears and gooseberries. It can be extracted from the citrus fruit juice by adding calcium oxide to form calcium citra...
This work provides a review about the biotechnological production of citric acid starting from the physicochemical properties and industrial applications, mainly in the food and pharmaceutical sectors. Several factors affecting citric acid fermentation are discussed, including carbon source, nitrogen and phosphate limitations, pH of culture medium, aeration, trace elements and morphology of the...
Today, biofuels represent a hot topic in the context of petroleum and adjacent products decrease. As biofuels production increase, so does the production of their major byproduct, namely crude glycerol. The efficient usage of raw glycerol will concur to the biodiesel viability. As an inevitable waste of biodiesel manufacturing, glycerol is potentially an attractive substrate for the production ...
