Selective enrichment of aromatic amino acid auxotrophs in Hansenula polymorpha.
Aromatic amino acid auxotrophs of the methanol-utilizing yeast Hansenula polymorpha were effectively selected by the use of nystatin and a medium that inhibits the growth of tyrosine auxotrophs. The procedure resulted in a frequency of aromatic auxotrophs of 2% of survivors and an enrichment of 20-fold. The new procedure also takes less time than traditional procedures. Of the auxotrophic mutan...
متن کاملPexophagy in Hansenula polymorpha.
In the yeast Hansenula polymorpha the development and turnover of peroxisomes is readily achieved by manipulation of the cultivation conditions. The organelles massively develop when the cells are incubated in the presence of methanol as the sole source of carbon and energy. However, they are rapidly and selectively degraded when methanol-grown cells are placed at conditions of repression of me...
متن کاملIsolation and symbiotic characterization of aromatic amino acid auxotrophs of Sinorhizobium meliloti.
Ten aromatic amino acid auxotrophs of Sinorhizobium meliloti (previously called Rhizobium meliloti) Rmd201 were generated by random mutagenesis with transposon Tn5 and their symbiotic properties were studied. Normal symbiotic activity, as indicated by morphological features, was observed in the tryptophan synthase mutants and the lone tyrosine mutant. The trpE and aro mutants fixed trace amount...
متن کاملMethanol oxidation and assimilation in Hansenula polymorpha
The metabolism of methanol was monitored in whole cells of the methylotrophic yeast Hansenula polymorpha by using [13C]methanol and n.m.r. in vivo. The main products observed under normal conditions were trehalose and glycerol, whereas cells that were starved before exposure to [13C]methanol also accumulated glutamate, glutamine and alanine; formate was also more prominent in spectra from starv...
متن کاملCreation of Hansenula polymorpha fatty acid auxotrophic mutants for genetic study of fatty acid biosynthesis
Three groups of Hansenula polymorpha fatty acid auxotrophic mutants were screened by their fatty acid requirement for growth. The mutants are saturated fatty acid auxotrophic mutants (Sfa), monounsaturated fatty acid auxotrophic mutants (Mfa) and polyunsaturated fatty acid auxotrophic mutants (Pfa) which required saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids...
