Growth of wild‐type O. polymorpha and mutants with deleted maltase (ΔMAL1) or α‐glucoside permease genes (ΔMAL2) on solid medium supplemented with substrates that are hydrolysed by the maltase of O. polymorpha. Sz. pombe strain 972 h– was studied for comparison; growth was evaluated on day 5 in the case of Op and on day 11 in the case of Sp
