Biotechnological options for lipid processing are briefly reviewed, with the focus on structural abundance of fatty acids in synthesised microbial lipids. The fortification of fermented material by dietary-valuable polyunsaturated fatty acids produced through semi-dry cultivation of filamentous fungi of the Mucoraceae family was studied. The resulting content of polyunsaturated acids depends on the fungal strain utilized. During semi-dry cultivation on cereal substrates with Mortierella isabelina M14, the amount of gamma-linolenic acid increased to 18.6 percent. With Mortierella alpina CCM 185, the amount of arachidic acid rose to more than 50 percent of total fatty acid content. Polyunsaturated fatty acid content in fermented substrate is dependent on the portion of saccharide material in the whole substrate as well as on cultivation conditions
