RESUMO
Wild-type strains of Saccharomycopsis lipolytica are able to use lysine as a carbon or a nitrogen source, but not as a unique source for both. Mutants were selected that could not use lysine either as a nitrogen or as a carbon source. Some of them, however, utilized N-6-acetyllysine or 5-aminovaleric acid. Many of the mutants appeared to be blocked in both utilizations, suggesting a unique pathway for lysine degradation (either as a carbon or as a nitrogen source). Genetic characterization of these mutants was achieved by complementation and recombination tests.
