RedCorn, Raymond M., M.S.E., Purdue University, December 2014. Identifying Conditions to Optimize Lactic Acid Production from Food Waste. Major Professor: Abigail Engelberth. There is an increased demand for lactic acid for the production of biopolymers and to aid nutrient removal in wastewater treatment. Food waste offers a source of soluble sugars to produce lactic acid, which does not increa...

The crop is a known source of Salmonella and Campylobacter contamination. We evaluated the use of selected organic acids (0.5% acetic, lactic, or formic) in drinking water during a simulated 8-h pretransport feed withdrawal (FW). Salmonella typhimurium was recovered from 53/100 control crops and from 45/100 of crops from acetic acid-treated broilers. However, treatment with lactic acid (31/100)...

Whey with a large amount of BOD(50000 PPM) is a dangerous environmental pollutant.this important source of lavtose(4-5%) is A USEFULL SUBSTRATE FOR A RANGE of fermentation processes.lacitic acid with swvwral applications in industries is one of these products.Specially L(+) isomer of this acid worthing 10 times as much as the mixture of L&D,is used in medical purposes such as absorbable surgica...

The degradation of lactic acid under anoxic conditions was studied in several strains of Lactobacillus buchneri and in close relatives such as Lactobacillus parabuchneri, Lactobacillus kefir, and Lactobacillus hilgardii. Of these lactobacilli, L. buchneri and L. parabuchneri were able to degrade lactic acid under anoxic conditions, without requiring an external electron acceptor. Each mole of l...

DUES, FEDERICO, GUADALUPE RAMOS, ESTHER AVELAR, AND MTGUEL LENNHOFF. Renal excretion of lactic acid in the dog. Am.J. Physiol. 216(l): 106-l 11. 1969.-The renal excretion of lactic acid was studied under different conditions in mongrel dogs, Previous reports that tubular reabsorption of lactic acid is rate limited were confirmed during experiments with rapid intravenous Na-lactate loading. Lact...

The simultaneous increases in blood lactic acid and erythrocytes after intense exercise could suggest a link between lactate and the erythropoiesis. However, the effects of lactic acid on erythropoiesis remain to be elucidated. Here, we utilized a mouse model to determine the role of lactic acid in this process in parallel with studies using leukaemic K562 cells. Treatment of K562 cells in vitr...

The plasma enzymes, lactic dehydrogenase, glutamic oxalacetic transaminase, and malic dehydrogenase, increased pro gressively in tumor-bearing rats. The amount of increase varied markedly with the type of tumor and the site of implantation. A lactic dehydrogenase agent could not be demonstrated in any of these animals. Isozyme patterns indicated the tumor was a significant contributor to the in...

A simple, efficient procedure for removing lactic acid and for reducing nonprotein nitrogen and ash in lactic acid whey has been developed. The procedure consists of culturing Candida ingens on the whey. This organism could assimilate >98% of the lactic acid and approximately 40% of the nonprotein nitrogen. Ash reduction of up to 45% resulted from precipitation of calcium apatite due to the inc...

Although l-malic acid is not an energy source for the malo-lactic organism Leuconostoc oenos (L. citrovorum) ML 34, the growth rate of the organism was found to be greatly increased by malo-lactic fermentation (the decarboxylation of l-malic acid to l-lactic acid). The stimulation was especially striking at the low pH (below pH 4) of wine, the natural habitat of this bacterium. The stimulation ...

Lactic acidosis is a form of metabolic acidosis with a high anion gap, reduced rate of arterial blood pH under 7.35 mmol/l, and lactic acid concentration over 7 mmol/l. In the literature we can find some descriptions of the cases of lactic acidosis in patients with severe systemic diseases (cancer, acquired immunodeficiency syndrome, sepsis, diabetes with cardiovascular disease and after organ ...
