Extracellular trehalose utilization by Saccharomyces cerevisiae.

Two haploid strains of Saccharomyces cerevisiae viz. MATalpha and MATa were grown in glucose and trehalose medium and growth patterns were compared. Both strains show similar growth, except for an extended lag phase in trehalose grown cells.

Regulation of trehalose metabolism by Adox and AdoMet in Saccharomyces cerevisiae.

Effect of a potent methylation inhibitor oxidized adenosine (Adox), and a universal methyl group donor S-adenosyl-L-methionine (AdoMet) on trehalose metabolism was studied in two haploids of S. cerevisiae of mating types MATalpha, met3 (6460 -8D) and MATa, leu2, ura3, his4 (8534 -10A). Trehalose level decreased in presence of Adox in both strains.
