to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...

A mutant strain of Streptomyces venezuelae was engineered by deletion of the entire gene cluster related to biosynthesis of the endogenous deoxysugar (TDP-D-desosamine) and replacement with genes required for biosynthesis of an intermediate sugar (TDP-4-keto-6-deoxy-D-glucose) or an exogenous sugar (TDP-D-olivose), from the oleandomycin and urdamycin deoxysugar pathways. The 'sugar-flexible' gl...

To The editor Erythritol (ERT; 1,2,3,4-butanetetrol) is a 4-carbon sugar alcohol prepared from glucose by fermentation,1 ERT occurs naturally in certain foods (mushroom, watermelon, pear, grape, wine, beer, soy sauce, cheese) at levels up to 0.13%. ERT is used to sweeten beverages and snack foods in Japan, where more than 125 million people consume more than 5 billion servings of ERT-sweetened ...

Background & Aim:   Changes in lifestyle, decrease in physical exercise along with incidence of obesity, hypertension and cardiovascular diseases indicate a need for low calorie formulations. The sweetness of Stevia, a natural sweetener, is estimated to be 300 times as much as that of sugar. Extraction of stevia leaves is considered a promoter of calorie balance and a beneficial part of a healt...

AIM The objective of this study was to evaluate the effects of sugar beet tubers as a replacer to green fodder on production performance and economics of lactating Surti buffaloes. MATERIALS AND METHODS This trial was conducted at the Livestock Research Station, Navsari Agricultural University, Navsari. Twenty lactating Surti buffaloes in a changeover experimental design were selected to asse...

Trp replacements for conserved Gly-Gly pairs between the N- and C-terminal six-helix bundles on the periplasmic side of lactose permease (LacY) cause complete loss of transport activity with little or no effect on sugar binding. Moreover, the detergent-solubilized mutants exhibit much greater thermal stability than WT LacY. A Cys replacement for Asn245, which is inaccessible/unreactive in WT La...
