Yeast extract was also reported as the best nitrogen source for Candida utilis, Saccharomyces cerevisiae  and Aspergillus ochraceus .Very low values (0.17 and 0.08 U/mL) of invertase activities were observed when urea was used as nitrogen source.
Similar optimum pH for invertase production was reported by Dworschack and Wickerham form Candida utilis and Saccharomyces crevisiae .
A wide range of microorganisms produce invertase such as Saccharomyces cerevisiae (Herwig et al., 2001), Candida utilis (Belcarz et al., 2002), Aspergillus niger (Romero-Gomez et al., 2000), Thermomyces lanuginosus (Chaudhari and Maheswari, 1996), Penicillium chrysogenum (Nuero and Reyes, 2002), Schwanniomyces occidentalis (Silveira et al., 2000).

Yeasts isolated from coastal sediments, including Candida lypolytica, Candida maltosa, Candida tropicalis, Candida utilis, Debaromyces hansenii, and Saccharomyces cerevisiae, have been reported to be capable of transforming polycyclic aromatic hydrocarbons (Cerniglia and Crow, 1981; Hofmann, 1986: McGillivray and Sharis, 1993).
