Thin stillage ph

WebFeb 1, 2005 · The original pH of thin stillage of 3.2–3.5 was not suitable for cell growth. The pH of thin stillage was then adjusted to 4, 5, 6 and 7 using 0.1 N of NaOH and G. lucidum was cultivated at 30 °C and 150 rpm for 7 days. With thin stillage, G. lucidum was able to grow from pH 4 to 7 ( Fig. 1 ). WebThe methods include admixing the compositions with a process stream for, for example, the extraction of oil from milled corn and residues from a fermentation step, including stillage (e.g., thin stillage or mid stillage), distiller's wet grain, distiller's dry grain and distiller's dry grains with solubles.
