Effect of molasses concentration and medium supplementation on the adaptability and viability of a high level ethanol-tolerant palm-wine Saccharomyces isolate

1994

Ezeogu, L.I. | Okolo, B.N.

A high level ethanol-tolerant palm wine Saccharomyces yeast showed good adaptability (2.6+/- 0.3 - 16.4+/- 0.7 days) in 5-30% unclarified molasses, and good viability in 10-30 degrees Brix molasses-based media at 30 degrees C for 3 days. Media supplementation with soyabean, castor oil bean or groundnut meals improved both yeast adaptability to molasses (X 29-33%) and yeast viability during batch fermentation.
