2.4. Controlled fermentation of cotton seeds for Owoh production
Owoh was prepared under controlled condition using cotton seeds (G. hirsutum). The seeds were removed from the lint and boiled under pressure for 1 h until they became soft. After boiling, the water was carefully discarded and the seeds soaked in fresh cold water overnight. The seed coat was later removed by pressing between the fingers to obtain the cotyledons. Thereafter, 36 g each of the dehulled cotton seeds was weighed and transferred into six sterilised 250 ml conical flasks. Sterilisation of the cotton seeds was carried out in an autoclave at 121 °C for 15 min minutes. The sterilised cotton seed was then allowed to cool in preparation for inoculation with the isolated bacterial cultures (B. subtilis, B. licheniformis, B. pumilus and Staphylococcus spp.). Inoculation of the cotton seeds was carried out singly with B. subtilis, B. licheniformis, B. pumilus and Staphylococcus spp.. Inoculation of the cotton seeds was also carried out in combinations with and without the Staphylococcus spp., 2×109 cfu/ml of the original dilution of the inoculums was used in inoculating in all the cases. Fermentation was thereafter carried out in a fermenter at 35±2 °C for 3 days.
