Abstract

Carotenoid pigment is an essential element in aquaculture, since it gives characteristic of color on shrimp and fish. Carotenoid pigments can be produced microbiologically using Paffia rhodozyma. Genetic improvement of the yeast, one of which can be accomplished by radiation mutation, will increase the production of carotenoid pigments. The aims of this study were to mutate P. rhodozyma using UV irradiation and to figure out pigment production by the mutant strains resulting from 30 minute-irradiation. Irradiated culture was incubated in dark condition and plated onto YMA media. Grown mutant colonies were collected in order to test for their pigment production. Pigment production was measured on the basis of extinction coefficient of 1%. The results showed that mutant strain encoded with MUV-1 produced the highest pigment at 179.96 mg/g dry weight cell, higher than the wild type (63.20 mg/g dry weight cell).

Abstract

Inulinolitic yeast isolated from dahlia tuber (Dahlia variabilis Willd) of Bandungan-Ambarawa, was found to produce inulinase enzyme (E.C.3.2.1.7).  Under tested fermentation condition, BAN-1 inulinase isolate showed enzymatic activity in dose dependent manner to the starter concentration. A maximum enzymatic activity of 0.582 IU was produced by adding starter concentration 10%. Based on morphological, physiological and biochamichal evaluation it was indentified that  the BAN-1 isolate is Pichia sp.
