Corn starch molasses is the concentrated mother liquor remaining from dextrose crystallization. It is used with cane molasses in cattle feeding regimes.

The Fermentation Process The process by which this antifungal substance is produced is an aerobic fermentation of an aquaous nutrient medium inoculated with a pimaricin-producing strain of Streptomycesgihrosporeus. The nutrient medium contains an assimilable source of carbon such as starch, molasses, or glycerol, an assimilable source of nitrogen such as corn steep liquor and Inorganic cations such as potassium, sodium or calcium, and anions such as sulfate, phosphate or chloride. Trace elements such as boron, molybdenum or copper are supplied as needed in the form of impurities by the other constituents of the medium. 

Several carbohydrates such as corn and potato starch, molasses and whey can be used to produce lactic acid. Starch must fust be hydrolysed to glucose by enzymatic hydrolysis then fermentation is performed in the second stage. The choice of carbohydrate material depends upon its availability, and pretreatment is required before fermentation. We shall describe the bioprocess for the production of lactic acid from whey. 

One of the commercial methods for production of lysine consists of a two-stage process using two species of bacteria. The carbon sources for production of amino acids are corn, potato starch, molasses, and whey. If starch is used, it must be hydrolysed to glucose to achieve higher yield. Escherichia coli is grown in a medium consisting of glycerol, corn-steep liquor and di-ammonium phosphate under aerobic conditions, with temperature and pH controlled. 

Raw materials for the fermentation of ethanol are sugar molasses (Brazil), com steep liquor and corn starch hydrolysate (USA). Industrial ethanol fermentation is highly developed and the stoichiometric yield can be as high as 1.9 mol mol-1 [25, 26]. The... 

Lactic acid is prepared by the fermentation of carbohydrates, such as glucose, sucrose, and lactose, with Bacillus acidi lacti or related microorganisms. On a commercial scale, whey, corn starch, potatoes, or molasses are used as a source of carbohydrate. Lactic acid may also be prepared synthetically by the reaction between acetaldehyde and carbon monoxide at 130-200°C under high pressure, or by the hydrolysis of hexoses with sodium hydroxide. 

However, for economy of production, maximum yields of alkaloids, and ease of recovery of the products, certain culture media containing relatively simple nutrient sources are preferred. For example, the media which are useful in the production of the alkaloids include an assimilable source of carbon such as glucose, sucrose, starch, molasses, dex-trins, corn steep solids, corn syrup liquor, sorbitol, mannitol, lactose, and the like. A preferred source of carbon is mannitol. Additionally, the media employed contain a source of assimilable nitrogen such as oatmeal meat extracts, peptones, amino acids and their mixtures, proteins and their hydrolysates, com steep liquor, soybean meal, peanut meal and ammonium salts of organic acids such as the citrate, acetate, malate, oxalate, succinate, tartrate and like salts. 

A bout 70 farm products of varying carbohydrate content furnish over 90% of all the raw materials for over 2000 varieties of confections. This paper is limited to the sweeteners used in confections, which on a dry basis are practically pure carbohydrates. Common sweeteners used in confections are refined crystalline cane or beet sugar, brown sugars, liquid sugars, corn sirup, dextrose, sorbitol, starches, molasses, honey, and maple sugar. 

Molasses is the thick brownish syrup by-product of the manufacture of cane or beet sugar from which part of the crystallizable sugar has been removed. However, molasses is also the by-product of several other industries. Citrus molasses is produced from the juice of citrus wastes. Wood molasses is a by-product of the manufacture of paper, fiber-board, and pure cellulose from wood it is an extract from the more soluble carbohydrates and minerals of the wood material. Starch molasses, Hydrol, is a by-product of the manufacture of dextrose (glucose) from starch derived from corn or grain sorghums in which the starch is hydrolyzed by use of enzymes and/or acid. Cane molasses and beet molasses are, by far, the most extensively used types of molasses. The different types of molasses are available in both liquid and dehydrated forms. 

Corn and molasses (sugarcane) were the principal raw materials for industrial solvent fermentation. Corn was primarily used during the era of the Weizmann process, which was based on C. acetobutylicum, whereas molasses was used when other bacteria replaced C. acetobutylicum in the industrial fermentation (see the section O Industrial Solvent Fermentation in this chapter). Besides corn and molasses, other starchy substrates were also used in industrial solvent fermentation outside North America. For example, the raw materials for solvent production hy Clostridium toanum Baba in Taiwan (Formosa) between 1947 and 1957 included sweet potato, casava, and wheat starch (a by-product of gluten production Yeh 1955 Anonymous 1956 1958). In addition, a diverse range of raw materials has been tested as alternative substrates for solvent production (McCutchan and Hickey 1954 Prescott and Duim 1959a Jones and Woods 1986 Diirre and Bahl 1996). 

Initially sugars were used extensively for the production of lA. However, using sugars as a carbon source is very expensive for industrial levels of production, which demand economically feasible substrates, such as starch, molasses, wood, or corn syrup hydrolyzates and other combinations (Klement et al., 2012 Klement and Biichs, 2013 Sieker et al., 2012). Nevertheless, beet or sugarcane molasses are the most commonly used carbon sources (Nubel and Ratajak, 1964), which are pretreated by ion exchange or ferrocyanide and subsequently used for fermentation (Bath and Schweiger, 1963). Apart from these, other varieties of... 

Molasses, fruit juice, corns, bagasse, Jerusalem artichockes, cassava, whey, sulfite liquor, saw dust and other wood by-products are used as substrates for alcohol and glycerin production. Starch-based substrates should be first saccharified by amylases prepared from barley, fungi or bacteria. Cellulosic materials must also be chemically or enzymatically hydrolyzed before being used as substrates for alcohol production. Clostridium species contain amylases and are able to convert starch and cellulose directly16). 

Traditional submerged fermentation typically uses cane and beet molasses as the source of carbohydrate for citric acid production. All molasses and other crude carbon sources may need pretreatment to regulate the proper amount of heavy metal ions. More recently, starch hydrolysates (corn syrups) have been... 

One source of ethanol is sugar-cane or the molasses remaining after the juice has been extracted. Other plants such as potatoes, corn and other grains require processing to convert the starch to sugar. This is done by enzymes. 

The carbon source most commonly used as a starting material is glucose, which is obtained by enzymatic hydrolysis of starch from corn, potato, and cassava. Waste molasses is also used since it is inexpensive, but it contains large amounts of biotin which inhibits the microbial glutamate synthesis. So it is necessary to add some other effective compounds to the medium to facilitate glutamate accumulation. 

All industrial biotechnological production processes use complex cultivation media which consist of agricultural by-products (beet or cane molasses, corn-steep liquor, cottonseed meal, whey permeate, peanut floiu-, soybean meal, distillation residues, etc.). In addition polysaccharides (starch, dextrose, malt extract, maltodextrins, etc.) and proteins (e.g. caseinate, yeast autolysates, etc.) are used as energy sources for the microorganisms and cells. These systems... 

The main substrates used in industrial microbiology today are glucose, sucrose, starch, glycerol, or acetate. Additionally, waste substrates as sugarcane and sugar beet molasses, corn steep liquor, deproteinized whey, or waste streams from food and paper industries are used very often as medium components. In some cases, complex vitamin and amino acid rich medium components like yeast extract, malt extract, or peptones have to be added to the media for optimal microbial growth and product formation. For the production of more complex compounds like antibiotics, chemical precursors have to be added sometimes. 

Other industrial fermentations include production of n-butanol, glycerol, acetic acid, citric acid, lactic acid, amino acids, vitamins, methane, and antibiotics. Several raw-materials are used, for example, starch sources such as corn and wheat, sugars, molasses, and organic wastes.
