| description | Beta-carotene pigment was extracted from 6 strains collected from different sources
related to some species of the genus Rhodotorula sp. The maximum productivity was in the
strain Rhodotorula mucilaginosa BA61 with amount 10.25 gm/l. The minimum productivity
was from the strain R. minuta BA78 with amount 5.39 gm/l. The effects of the chemical
mutagen ( MNNG ) and the physical mutagen ( UVC ) on the viability of the strains was
studied. The results revealed that the chemical mutagen ( MNNG ) with the concentration 0.2
mg/ml has the clear effect on the viability of the strains, which killing percentage reached to
65.91% in the strain R. minuta BA78. Results of the study of mutagenesis with UVC showed
that increase in killing percentage for all the studied strains with the increase of radiation
period. The maximum effect was with the strain R. minuta BA78, the killing percentage reach
to 100% with the radiation period 20 minute. The companying effects of chemical with the
concentration 0.2 mg / ml and physical mutagen was studied. The result showed increase in
killing percentage for the studied strains which reach to 100% with the radiation period 15
and 20 minute for the strain R. minuta BA78. The maximum effect on Beta-carotene
production was on the strain R. mucilaginosa BA61, the productivity reach to maximum with
amount 11. 45gm / l. |
