The Soluble Carbohydrates of Aspergillus clavatus

The Metabolic Stability of Carbohydrates in Walls of Hyphae of Aspergillus clavatus

The metabolic stability of carbohydrates in walls of hyphae of Aspergillus clavatus was investigated through measurements of mycelial isotope distribution from [U14C]glucose and the ,H/14C ratios of re-isolated monosaccharides, when the organism was grown on labelled glucose as sole carbon source. The results suggest that glucose and glucosamine became metabolically inert once they had been inc...

Clavacin, an Antibiotic Substance from Aspergillus Clavatus*

In 1942 Wiesner (1) and Waksman, Horning, and Spencer (2) demonstrated that filtrates from cultures of Aspergillus clavatus grown upon synthetic media possess antibiotic activity. These investigators extracted and partially purified the active material (which was named clavacin by Waksman) but did not report its isolation in pure form. As a result of the observations made by Waksman’s group, pa...

Soluble Carbohydrates in Soybean

Soybean seeds accumulate soluble carbohydrates throughout development and maturation. Soluble carbohydrates may have important roles in seed germination, seed desiccation tolerance, and cold stress tolerance. The analysis of soluble carbohydrates in soybean seeds and other plant parts at various growth stages (Obendorf et al., 1998b & 2009; Kosina et al., 2009), under environmental stresses (Bl...

The Effect of Zinc excess on antioxidant enzymes, proline and soluble carbohydrates in Plantago major L.

The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried o...
