An extracellular pigment-producing ascomycetous filamentous
fungi belonging to the genera Penicillium was
obtained from soil and
its optimal culture conditions investigated. The optimal
culture conditions for pigment production were as follows;
soluble starch 2% (670 units), peptone (880 units), pH 9.0
(900 units); temperature 30˚C (950 units), agitation 200 rpm
(920 units), and inoculums age 4 days (850 units).
The
properties of pigments and their residual content after
exposing to the various physico-chemical conditions like
sunlight, fluorescent light, UV light, high temperature and
preservatives (sodium bisulfate, ascorbic acid and citric
acid) are also investigated.
Key words:
Penicillium, pigment, physical factor, stability. |
