Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell

Algae are simple organisms that typically produce their own food through photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very

MEDIA FORMULATION Medium formulation is an essential stage in the design of fermentation process. Most fermentation media require liquid media‚ although some solid-substrate fermentations are also operated. Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process (1). There are several stages where media are required in a fermentation process; inoculum (starter culture)‚ propagation steps‚ pilot-scale fermentations

compaction is described in relation to soil physical factors‚ root growth‚ and nutrient uptake by crop plants; rice growth and yield. In compaction‚ soil solids are rearranged with compression of liquid and gaseous phases accompanied by volume change. Soil compaction affects water retention characteristics‚ water intake rates‚ and gaseous exchange. In compacted soil‚ bulk density‚ microvoids‚ thermal conductivity‚ and nutrient mobility increase and macrovoids‚ hydraulic conductivity‚ and water
