The production of natural red pigment using the filamentous fungus Pencillium purpurgenium under different growth forms of inocula (mycelia and spores) was investigated. Meanwhile, different physiological condition involving magnesium sulphate concentration, inoculums size and different age as well as some additives were tested. The results showed that the specific production of pigment was obtained by using mycelia as inocula, the yield increased by 30.08% as compared to spore form. The study extended to dye wool fibers with the extracted pigment using innovation technique to save energy and time. In order to obtain color of aimed specific red hue, the influence of certain dyeing process condition namely dyestuff concentration, pH, temperature, and duration of the dyeing process has been reported.
