Bepaling van lasalocid-natrium door middel van HPLC
, 1981 Lasalocid-natrium is volgens methode EEG doc. 1089/VI/81-E onderzocht in twee mengvoeders. De storende invloed van monensin, salinomycine en narasin werd eveneens bekeken. Lasalocid-natrium wordt als coccidiostaticum toegepast voor het gebruik van kippen

Sequential Enzymatic Epoxidation Involved in Polyether Lasalocid Biosynthesis
, 2016 Enantioselective epoxidation followed by regioselective epoxide opening reaction are the key processes in construction of the polyether skeleton. Recent genetic analysis of ionophore polyether biosynthetic gene clusters suggested that flavin-containing ...
