34 Extractives or Corn Steep Liquor (CSL). Corn steep liquor is a mixture of soluble protein, amino acids, 35 carbohydrates, organic acids (e.g., lactic acid), vitamins, and minerals.

36 37 Wet corn milling is used to produce numerous corn based products that are subsequently used as biofuel, 38 ingredients in food, and for livestock feed.

The production performance of Cc0 and Cc6 strains was investigated in pilot-scale fermentations. For this purpose, a medium based on corn steep liquor was used because corn steep liquor is typically applied for industrial amino acid production, and the fermentations were performed in a L bioreactor (Fig.B-D).Pilot-scale fermentation of the final strain resulted in g/L of l.

Science 14 Dec Vol. Issuepp. DOI: /science Finishing yearling steers fed a corn-based diet containing steep liquor had statistically similar live performance as steers fed the control diet. Numerically steers fed the steep containing diet were 6% more efficient.

Steers fed steep liquor tended to contain less carcass fat (as measured by intramuscular marbling) less kidney, heart and pelvic fat, and less backfat thickness.

Aims: To evaluate cellulase production by Streptomyces malaysiensis in submerged fermentation using brewer’s spent grain (BSG) and wheat bran (WB) as carbon source, and corn steep liquor (CSL) as nitrogen source, as compared to yeast extract (YE), and partial characterization of the crude enzyme.

Corn steep liquor contain phenylethlamine when incorporated, it yield benzyl penicillin. Phenylacetic acid is widely used precursor in penicillin production.

nutrients addition. In the present research addition of corn steep liquor (CSL), a by-product from corn starch processing, was considered due to its typical content of many vitamins, amino acids, nitrogen compounds and mineral matters, which makes it a very suitable nutritious substratum in industrial fermentations (Filipović, ).

steep liquor for 84 days. Feeding corn steep liquor did not affect performance of the steers or carcass characteristics. Based on value of feeds replaced in the diet, steep liquor had a value of $55 to $60/ton (50% dry matter) when used to replace corn and supplemental protein in a corn-based finishing diet.

Introduction Corn steep liquor i s a. Corn Steep Liquor (CSL) Corn steep liquor is a high-protein, high-energy feed ingredient made from the soluble parts of the corn kernel through a steeping process.

It is a viscous liquid mixture consisting entirely of water-soluble components of corn steeped in water. CSL is a kind of byproduct produced in the processing course of corn starch. It is used as a nutrient for microorganisms in the production of enzymes, antibiotics, and 53 other fermentation products.

It is sometimes combined with other ingredients in corn gluten feed and 54 widely used in complete feeds for dairy and cattle, poultry, swine, and pet foods.

Nitrogen contents of corn light steep-water solubles and centrifuged solids were and %, respectively, ona drybasis. Corn light steep-watersolubles accounted for 93% of the total weight and 93% oftotal nitrogen ofcorn light steep waterona dry basis.
