Efficient enzymatic syntheses of isosteric phosphono analogues of sugar nucleotides have been accomplished using a thymidylyltransferase.

sugar beet (beta vulgaris) is one of the hosts for different root-knot nematode species. in this study, firstly the effect of different inoculum levels including 250+250, 500, 500+250, 750, 500+500 and 1000 second stage juveniles of meloidogyne javanica were evaluated on a susceptible variety named jolgeh. the results showed that all inoculum levels were suitable for infection on sugar beet pla...

BACKGROUND Fine milling of dry lignocellulosic biomass, without prior chemical pretreatment, can produce a high percent theoretical yield of sugars during subsequent enzymatic saccharification. However, the high sugar yields, necessary for a commercial biofuels process, are costly, with the milling energy input, necessary to achieve such yields even exceeding the energy content of the biomass. ...

the sugarcane whitefly, n. andropogonis, sucks severely the sap of plant and produces a lot of honey-dew. this study was conducted to quantify the relationships between whitefly damage and sugar quality in order to estimate the monetary loss occurring at different levels of damage at harvest time. during this trial, the number of infected leaves was expressed as an index. the investigation was ...

Lactose, the disacch arid e commonly known as milk sugar , has for many years been of commercial impor tance. U nt il r ecently i ts principal usc was in the manufacture of pharmaceu ticals, food products, and in th e preparation of modifi ed di ets; however, the penicillium industry now also r equires large quantiti es of this sugar. ! In th e presen t investigation measurements h ave been mad...

A rapid and simple procedure was developed for the preparation of a highly stable and leach-proof glucose oxidase (GOx)-bound glassy carbon electrode (GCE). Crosslinked GOx via glutaraldehyde was drop-cast on a KOH-pretreated GCE followed by drop-casting of 3-aminopropyltriethoxysilane (APTES) to form a stable bioactive layer. At -0.45 V, the biosensor exhibited a wide dynamic detection range o...

Terrestrial transport biofuels differ in their ability to replace fossil fuels. When both the conversion of solar energy into biomass and the life cycle inputs of fossil fuels are considered, ethanol from sugarcane and biodiesel from palm oil do relatively well, if compared with ethanol from corn, sugar beet or wheat and biodiesel from rapeseed. When terrestrial biofuels are to replace mineral ...

The monoclonal antibody (MCA) SucroTest is a commercially available kit (Midland Research Laboratories Inc) for the specific analysis of dextran in juices and sugar. The method is simple and quick and is based on the selective and specific reaction between the antibody and its antigen (in this case dextran). The resultant insoluble complex causes turbidity which is measured after a set time usi...

A series of novel glycosylthiadiazole derivatives, namely 2-phenylamino-5-glycosyl-1,3,4-thiadiazoles, were designed and synthesized by condensation between sugar aldehydes A/B and substituted thiosemicarbazide C followed by oxidative cyclization by treating with manganese dioxide. The original fungicidal activities results showed that some title compounds exhibited excellent fungicidal activit...

Several factors associated with senescence of the rind of the Navel orange fruit and their response to GA were studied from the time of color change, green to orange, until the fruit passed the point of any commercial value. This period is typified by a doubling in the concentration of sugar, a decrease in glucose respiration, and increase in the ratio of K/Ca+Mg. No seasonal trend could be ass...
