Bacterial lipases are mostly extracellular and are greatly
influenced by nutritional and physico-chemical factors,
such as temperature, pH, nitrogen and carbon sources,
presence of lipids, inorganic salts, agitation and dissolved
oxygen concentration (Brune and Gotz 1992; Aires-Barros
et al. 1994; Jaeger et al. 1994; Kim et al. 1996). A list of
various fermentation conditions used with different bacteria
is presented in Table 3.
