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.

WebAug 9, 2011 · Initially, the thin stillage was prepared as a substrate for the medium by filtering it through a Whatman No. 1 filter for the removal of insoluble material. To the clarified thin stillage, 9% (w/v) K 2 CO 3 was added as a neutralizing agent (Andersson et al. 2009) and its pH was adjusted to 6.0. WebThis study determined the effect of pH, type of acid used to adjust pH and Reynolds number on fouling by thin stillage from a commercial dry grind corn (DGC) process used to produce ethanol from corn. Thin stillage is a DGC process stream consisting primarily of unfermented dissolved solids that are concentrated by evaporators to produce an animal … is child marriage allowed in america

WebNov 15, 2024 · The thin stillage flow was found to be 57.16 t/h. The thin stillage is reinserted into the process through the evaporation of the water fraction and used to produce more the DDGS. However, based on the mass balance from the experimental data, the reinsertion of the thin stillage into the original process yields approximately 33 % more DDGS. WebJul 15, 2014 · To avoid these problems, a new process was proposed ( Fig. 1 c), in which a portion of the thin stillage (pH 4.2–4.6) was mixed with the digestate to decrease the pH of the process water, thereby eliminating the consumption of sulfuric acid. In this study, a new process was developed and assessed at the lab and on a pilot scale. 2.
