Diseases caused by Sclerotinia spp., generally known as 'white mold', can affect hundreds of plant species including many important crops. The pathogens are favored by cool, moist conditions, but show surprisingly broad ecological distributions. 1 Several other Sclerotinia species cause diseases other than white mold.
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. The primary source of oxygen for a pond is from microscopic algae (phytoplankton) or submerged plants.In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water.xygen dissolves in water at very low concentrations. Our atmosphere is 20% oxygen or 200,000 ppm but seldom will a pond have more than 10 ppm oxygen dissolved in itsâ water. Dissolved oxygen concentrations below 3 ppm stress most warmwater species of fish and concentrations below 2 ppm will kill some species.
Glycolysis is a metabolic process that yields ATP. You should note that an oxidation step, using NAD as the oxidizing agent, occurs in this metabolic sequence. Molecular oxygen is not used anywhere in this process and this is why glycolysis is described as an anaerobic process. Glycolysis can in fact occur in the presence of molecular oxygen, as is seen in the erythrocyte, but oxygen is not needed for this process and can not be used even if it is present. You will see that in this scheme lactate is the product of this route for the anaerobic use of glucose for ATP synthesis.
