Pichia kudriavzevii is a non-conventional and usually diploid yeast, also known as Issatchenkia orientalis (teleomorph) and Candida krusei (anamorph) (1), which shows unique traits valuable in developing solutions for energy and materials sciences. One such biotechnological application is the production of organic acids (e.g., succinic acid, itaconic acid) (2-4), which can be accomplished under low-pH conditions (e.g., pH 2.0) (5) , at warm temperatures (e.g., 44°C) (6) and using pre-treated plant biomass as starting material, allowing for biorefinery processes to be environmentally and energetically competitive (7). The sequenced strain YB-431 was isolated from pineapple peals (obtained from the ARS culture collection - NRRL) and differentiate itself from a pool of various strains for its native capacity when screened against higher production of dicarboxylic acids.
