BACKGROUND Tarhana, a wheat-yoghurt fermented mixture, is considered as a good source of saccharides, proteins, some vitamins and minerals. Moreover, their preparation is inexpensive and lactic acid fermentation offers benefits like product preservation, enhancement of nutritive value and sensory properties improvement. The aim of this work was to evaluate changes of some chemical parameters du...

An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...

Statistical experimental design was applied for the optimization of medium constituents for citric acid production by Yarrowia lipolytica NCIM 3589 in submerged fermentation using raw glycerol as the carbon source. Response surface methodology (RSM) involving central composite design (CCD) was adopted to evaluate the amount of citric acid produced by most important factors, such as carbon conce...

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...

This study revealed for the first time dynamic changes of bacterial community and physic-chemical properties in process tomatoes fermentation. In early phase fermentation, Proteobacteria Firmicutes account 86.04% 9.97%, respectively. Then, replaced to be dominant phylum from day 10. Among then, Lactobacillus decreased 20 30 days then rapidly increased. The total sugar showed a gradual while nit...

Increasing demand for plant oil for food, feed, and fuel production has led to food-fuel competition, higher plant lipid cost, and more need for agricultural land. On the other hand, the growing global production of biodiesel has increased the production of glycerol as a by-product. Efficient utilization of this by-product can reduce biodiesel production costs. We engineered Yarrowia lipolytica...

Citric acid is the most important organic produced in tonnage and extensively used food pharmaceutical industries. It mainly by submerged fermentation using Aspergillus niger or Candida sp. from different sources of carbohydrates, such as molasses starch-based media. In view surges demand growing markets, there always a need for discovery development better production techniques solutions to im...
