Development of methodology for the recovery of citric acid from the fermented broth involves standardization of the various parameters to achieve maximum performance in terms of recovery and optimum conditions. The present investigation was carried out to study the purification of citric acid from fermented broth by calcium carbonate precipitation and subsequent acid hydrolysis. The parameters ...

Citric acid is a regular ingredient in many vase solution formulations but pre-harvest use of citric acid is a novel method in vase life extension of cut flowers, which is reported on tuberose earlier. In order to verify previous result, and check for possible substitution of citric acid by malic acid, the current research was designed. Citric acid (0, 0.075, 0.15% w/v) and malic acid (0, 0.075...

Production of citric acid from sodium citrate was carried out by electrodialysis (ED), using bipolar membranes (BP) prepared from poly(phenylene oxide) (PPO). The process feasibility was tested using a laboratory ED-cell with an effective area 20 cm. Based on the configuration of BP-cation membranes (C)-BP, the performances of various sodium sulfate concentrations and sodium citrate concentrati...

Several bioassays were conducted with young chicks and pigs fed phosphorus (P)-deficient corn-soybean meal diets. With diets for chicks containing .62% Ca and .42% P (.10% available P), graded doses of a citric acid + sodium citrate (1:1, wt:wt) mixture (0, 1, 2, 4, or 6% of diet) resulted in linear (P < .01) increases in both weight gain and tibia ash. Relative to chicks fed no citric acid, ti...

Lanhouin is a traditional fermented salted fish made from the spontaneous and uncontrolled fermentation of whole salted cassava fish (Pseudotolithus senegalensis) mainly produced in the coastal regions of West Africa. The combined effects of NaCl, citric acid concentration, and marination time on the physicochemical and microbiological characteristics of the fish fillet used for Lanhouin produc...

fungal biomass of a. niger, the byproduct of citric acid fermentation, proved to be a worth biomaterial which can be so beneficial and practical. in environmental case, it can be a useful biosorbent for decolorization and detoxitation of wastewater samples. it can also be used as a cheap and suitable source for commercial production of some expensive and useful biopolymers such as chitin, chito...

The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...

Chemical engineering deals with synthesis of various chemicals in economical and efficient manner. Raw material is important aspect for cost effective manufacturing of chemicals. Biological methods for syntheis consume less energy and are very economical for production of chemicals such as ethanol, acetic acid, citric acid, lactic acid etc. Waste solid materials such as molassis, fruit peels, w...

Streptococcus paracitrovorus (Hammer, 1920) is a heterofermentative lactic acid organism associated with Streptococcus lactis in butter cultures. In milk culture it is known to ferment citric acid with the subsequent production of diacetyl, the principal flavor and aroma constituent of cultured butter. The breakdown of citrates in milk by Streptococcus citrovorus and Streptococcus paracitrovoru...

The “citric acid cycle” hypothesis of carbohydrate oxidation has stimulated an interest in the general relationship of citric acid to carbohydrate metabolism. Krebs and Johnson (1937, a) and Krebs (1937) have presented evidence which they believe demonstrates that a catalytic system composed of certain dicarboxylic acids and citric acid “outlines the principal pathway of the oxidative breakdown...
