Shared control of maltose and trehalose utilization in Candida utilis

Shared control of maltose and trehalose utilization in Candida utilis.

Trehalose biosynthesis and its hydrolysis have been extensively studied in yeast, but few reports have addressed the catabolism of exogenously supplied trehalose. Here we report the catabolism of exogenous trehalose by Candida utilis. In contrast to the biphasic growth in glucose, the growth of C. utilis in a mineral medium with trehalose as the sole carbon and energy source is aerobic and exhi...

Mechanism of glucose and maltose transport in plasma-membrane vesicles from the yeast Candida utilis.

Transport of glucose and maltose was studied in plasma-membrane vesicles from Candida utilis. The yeast was grown on a mixture of glucose and maltose in aerobic carbon-limited continuous cultures which enabled transport to be studied for both sugars with the same vesicles. Vesicles were prepared by fusion of isolated plasma membranes with proteoliposomes containing bovine heart cytochrome c oxi...

Mitoribosomes from Candida Utilis

Highly purified mitochondrial ribosomes (mitoribosomes) have been obtained from the yeast Candida utilis. Sedimentation analysis in sucrose gradients made in 5 mM MgCl(2), 1 mM Tris, pH 7.4 and 50 mM KCl clearly distinguishes mitoribosomes (72S) from cytoplasmic ribosomes (cytoribosomes) (78S). Mitoribosomes are completely dissociated into 50S and 36S subunits at 10(-4)M MgCl(2) whereas complet...

Biosynthesis of polynucleotides. 6. The utilization of glucose in the synthesis of ribose in Candida utilis.

Enhancement of L-asparaginase Production by Candida utilis in a 13L Fermenter and its Purification

L- asparaginase enzyme is a renown enzyme due to its chemotherapeutic properties. This enzyme could also be employed in food processing technology. The present study aimed, optimizing the agitation and aeration rate in L-asparaginase production, using Candida utilis, ATCC 9950 in batch fermentation system. Beet molasses used as the carbohydrate source for enzyme production. A maximum asparagina...
