Maize (Zea mays), also called corn, is believed to have originated in central Mexico 7000 years ago from a wild grass, and Native Americans transformed maize into a better source of food. Maize contains approximately 72% starch, 10% protein, and 4% fat, supplying an energy density of 365 Kcal/100 g and is grown throughout the world, with the United States, China, and Brazil being the top three ...

Water is prime requirement for surviving of any living beings.  The existence of surface water and groundwater sources are used for domestic, agriculture and industrial purposes in all over the world. Fresh water from both the water sources is highly contaminated in recent years because of rapid population growth, modern agriculture and industrial growth. Among them, contamination of water sour...

The intent of this study was to evaluate the ability low-cost polyacrylamide/starch hybrid hydrogels in removing organic pollutants from wastewater, using phenol as a model compound, besides investigating adsorption/desorption behavior function composition. results indicated that hydrogel with lowest amount starch and crosslinking agent exhibited maximum adsorption capacity, 21 mg g−1. isotherm...

screening of3000 soil samples collected from cities of four different provinces of iran for starch-hydrolysing bacteria revealed that the nature is enriched with streptomyces species capable of producing amylolytic enzymes. among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characterization...

During the last two decades, and particularly during the last few years, the environmental sector has shown a largely growing interest in the treatment of different types of water and wastewater by electrocoagulation (EC). The aim of this work was to review studies, conducted mainly during 2008-2011, on the wide and versatile range of feasible EC applications employed in the purification of dif...

The table olive industry generates high amounts of wastewater annually during the alkaline treatment, fermentation, and washing steps olives. High conductivity salt content, as well organic biophenol contents these waters, is a worldwide problem, especially in Mediterranean region, which major producing area. There wide variety bioactives found derived from processing. main compounds wastewater...

One of the industries that uses large amounts water is food industry. Industrial, domestic managers production process stand out with it and enter environment surrounded by contaminated effluents. Their main feature high content dissolved organic matter nitrogen. You can also create wall to aggregate-resistant colloids, which include animal vegetable fats, proteins, starch, sugar, as well salts...

The treatment of the yeast industry wastewater was investigated by nanofiltration (NF) membrane process on a pilot scale. Two wastewaters were used as feed: (i) dilute wastewater with COD 2000 mg/L and (ii) concentrate wastewater with COD 8000 mg/L. The permeate flux, COD retention, color and electrical conductivity (EC) removal were evaluated in relation to trans-membrane pressure and long-ter...

Recently natural polysaccharides have been developed as environmentally friendly materials for removing toxic pollutants from aqueous solutions. Amongst numerous polysaccharides starch is an abundant, inexpensive, renewable and fully biodegradable natural raw material. The main criterion in the design of modified starch with substantial stability is fast complexation of toxic pollutants. A new ...
