The modified API 20C system (Analytab Products, Inc.) containing 19 carbohydrate assimilation tests was used to identify stock cultures of clinical isolates and routine clinical isolates from the Mayo Clinic mycology laboratory. The system provided correct identifications for 96% of the 505 organisms tested. The API 20C represents a commercial system useful for the identification of yeasts from...

Gea-Izquierdo et al. present a landscape-scale biogeochemical model for the exchange of carbon over forest ecosystems. They describe adaptations to the basic model formulation to try and better represent the assimilation of carbon and its allocation within the tree. Key aspects of their formulation are the incorporation of nonstructural carbohydrate storage and the medium-term acclimation of ph...

This short review is devoted to considerations of acute regulation rather than longerterm effects achieved through dietary manipulation or massive and prolonged hormone administration in t h o . Adipose-tissue fatty acid metabolism is conveniently divided into: assimilation of fatty acids from circulating lipoproteins; synthesis de novo of fatty acids, mainly from carbohydrate; assembly of tria...

Heavy metal contamination in crops is a worldwide problem that requires accurate and timely monitoring. This study is aimed at improving the accuracy of monitoring heavy metal stress levels in rice utilizing remote sensing data. An assimilation framework based on remote sensing and improved crop growth model was developed to continuously monitor heavy metal stress levels over the entire period ...

One of the earliest examinations of the response of the human organism to the administration of sugar was made by Worm-Muller (1884), who published observations on the alimentary glycosuria of two healthy men. He found that these subjects, after being for some time on a diet very low in carbohydrate, showed a detectable glycosuria when given 50 gm. of glucose or sucrose or 100 gm. of lactose. T...

Several aspects of bacterial glucose assimilation and bacterial production (BP) were investigated over 2 d in the upper 300 m of the Gulf of Mexico. Glucose concentrations ranged from 2 to 15 nM in surface seawater; glucose utilization rates were 1–3 nM d21 in the upper 150 m of the water column and 0.02–0.8 nM d21 in deeper water (150–300 m). Turnover of glucose and bacteria were similar and w...

effect of different co2 concentrations on sucrose metabolizing enzymes and on carbohydrate metabolism was studied for eight blackgram (vigna mungo l. hepper) genotypes grown in open top chambers under ambient (380 µmol mol-1) vs. elevated co2 (550 and 700 µmol mol-1) levels. the higher acid invertase activity over neutral invertase indicated the major role of acid invertase in sucrose breakdown...

The oxidative assimilation of carbon compounds by nonproliferating yeast cells has been studied by several workers. Winzler (1940) found that when Saccharomyces cerevisiae was allowed to oxidize sodium acetate only 66 per cent of the substrate was oxidized; the remainder was incorporated into the cell. Winzler and Baumberger (1938) found that when glucose was the substrate only 26.5 per cent of...

Asian grapevine rust (Phakopsora euvitis) is a serious disease, which causes severe leaf necrosis and early plant defoliation. These symptoms are unusual for a strict biotrophic pathogen. This work was performed to quantify the effects of P. euvitis on photosynthesis, carbohydrates, and biomass accumulation of grapevine. The reduction in photosynthetic efficiency of the green leaf tissue surrou...
