Streptomyces misionensis strain PESB-25 was screened and selected for its ability to secrete cellulases. Cells were grown in a liquid medium containing sugarcane bagasse (SCB) as carbon source and corn steep liquor (CSL) as nitrogen source, whose concentrations were optimized using response surface methodology (RSM). A peak of endoglucanase accumulation (1.01 U · mL(-1)) was observed in a mediu...

There is growing miasma in our national correspondence over the increasing heft and metabolic dysfunction of everyday Americans. The origin of this mounting poundage has many parents, not the least of which is our appetite for nutritive (read caloric) sweeteners in processed foods and beverages. The culprit derivatives taking most heat today are various formulations of added fructose. Bray et a...

Currently, corn is used to produce more than 85% of the world's high fructose syrup (HFS). There is a search for alternative HFS substrates because of increased food demand and shrinking economies, especially in the developing world. The sweet potato is a feasible, alternative raw material. This study isomerized a high glucose sweet potato starch syrup (SPSS) and determined its sugar profile, m...

F ructose is a sweet tasting sugar that is found naturally in fruits and some vegetables and has been part of the human diet—in modest amounts—for eons. The increasing consumption of sugar has dramatically increased our exposure to fructose (1). Sugar consumption has risen more than 40-fold since the Declaration of Independence was signed 250 years ago, andmore than 40% of the added sugars in o...

N-terminal sequence analysis shows that the limited proteolysis of Escherichia coli phosphofructokinase results in the removal of the 40-50 C-terminal residues of each chain. When tetrameric, this proteolyzed derivative is still active albeit insensitive to allosteric effectors (Le Bras, G., and Garel, J.-R. (1982) Biochemistry 21, 6656-6660). In the absence of fructose 6-phosphate, the proteol...

Of about 10 billion bushels of corn that are grown each year in the United States, less than 2% is processed directly into food products, and about 18% is processed into intermediates such as high-fructose corn syrup, ethanol, and cornstarch. The vast majority of the annual crop is used domestically for animal feed (60%), and about 16% is exported. Thus, any program for controlling residues of ...

Dietary fructose intake is increasing. It is increasing primarily from added sugars, including sucrose and high fructose corn syrup, and correlates epidemiologically with the rising prevalence of metabolic syndrome and hypertension worldwide. The administration of fructose to animals and humans increases BP and the development of metabolic syndrome. These changes occur independently of caloric ...

Background: Honey has a lot of reputation because of its supposed medicinal properties. In this study, Hydroxymethylfurfural (HMF), sugars, and Fructose/Glucose ratio of honey in Bangladesh were assessed for adulteration and authenticity evaluation. Methods: Seventy honey samples collected from different districts of Bangladesh were analyzed by High Performance Liquid Chromatography (HPLC) for...
