Characterization of growth stimulants in corn steep for lactic streptococci.

The production of acid in milk cultures of lactic streptococci was stimulated by the addition of corn steep liquor. Separation by ion-exchange and paper chromatography indicated the presence of four major stimulatory components in the corn steep. Some variation was noted in the response of the lactic streptococci to the individual stimulatory components. The four components were further purifie...

Some characteristics of a growth stimulant in corn steep liquor for Lactobacillus casei.

In a previous report by Kennedy and Speck (1955), it was shown that the addition of corn steep liquor to milk stimulated the growth of several species of lactic acid bacteria. Additional studies (Kennedy et al., 1955) have shown the stimulatory factor to be different from other stimulatory factors reported for the lactic acid organisms. These investigators also observed that corn steep appeared...

Morphology of the bacteriophages of lactic streptococci.

Electron microscope studies have been made of a number of phages of lactic streptococci, seven of which were phages of Streptococcus lactis C10. Two of the phages are thought to be identical; five have been classified by the method of Tikhonenko as belonging to group IV (phages with noncontractile tails) with type III tail plates; one belongs to group V (phages with tails possessing a contracti...

Pilot-Scale Lactic Acid Production via Batch Culturing of Lactobacillus sp. RKY2 Using Corn Steep Liquor As a Nitrogen Source

In this study, the determination of the efficiency of a pilot-scale fermentation process using corn steep liquor as a nitrogen source was attempted in order to produce lactic acid via batch culturing of Lactobacillus sp. RKY2. Using pure glucose, fermentation efficiency characteristics, such as final lactic acid, cell growth, yield, and productivity were not substantially influenced by the scal...

Characterization of light gluten and light steep water from a corn wet milling plant.

The primary commodity of corn wet milling is starch, but two coproducts (corn gluten feed, CGF and corn gluten meal, CGM) also are produced. CGM and CGF are marketed as animal foodstuffs and are important economically; however, variation in composition reduces quality. There are few data on the effect of composition of the parent process streams, light steep water (LSW) and light gluten (LG), r...
