Preparations of soluble and immobilized fungus lipases showing high catalityc acivity in hydrolysis of acyloglycerols in water, synthesis of esters of higher fatty acids in hydrolysis of acyloglycerols in water and synthsis of esters of higher fatty acids inorganic solvents milieu were obtained.The course of reaction andthe activity dependedon: the lipase source, the form of enzyme and the reaction milieu.The studied extacellular lipases, in a water - soluble form (especially R.nigricans lipase), exibited high activity in olive oil hydrolisis.The lipases were not active in esters synthesis in diphase system: water-organic solvent.Being drained by liophilization they demonstrated the activity in esters synthesis inorgnic solvents milieu.The endocellular lipases immobilized in situshowed the hihgest activity in the synthesis of esters in organic milieu.These enzymes can also be used for hydrolysis of acyloglycerols.The obtained liquid and immobilized mycelial preparations demonstrate activity which qualifies them for industrial scale application.
