acidity‚ turbidity levels and temperature which causes an unnatural environment for the native animals and plants. (refer to figure 2.1). Furthermore‚ this can also contribute to the formation of patches of blue-green algae (cyanobacteria) as high content of phosphates are emitted from stormwater drainage systems and human domestic pet faeces that they do not clean up. The blue-green algae will affect the aquatic ecosystems as it will use large amounts of carbon dioxide‚ and increase turbidity

Aseptic Technique and Culturing Microbes‚ Lab #3 Purpose: The purpose of the this experiment is to learn to transfer microorganisms to a nutrient medium to promote growth using aseptic techniques. which are a method used to prevent unwanted organisms from contaminating a medium. We will also learn about different types of culture media‚ including MRS broth and nutrient broth‚ learn about oxygen and temperature requirements for microbial growth and how to control microbial growth. Procedure:

Turbidity measurement The concentration of TiO2 suspension was determined based on the concentration – turbidity calibration curve prepared with known concentrations (Figure 3.11). The turbidity of the suspension was measured using a turbidity meter WTW-Turb 550 (Germany). Figure 3.11. Calibration graph between TiO2 concentration and turbidity 3.5.3.

INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria

Chapter one Introduction In industrial processing water is used in numerous applications requiring likewise different qualities of water. Examples of different use are cooling water‚ water for rinsing and chemical production‚ boiler feed water‚ purified water‚ water for injection‚ just to mention a few of those. On a chemical site or within a factory commonly a central water production unit is providing the basic amount of water in several qualities. These water supply units are using more and

happens to be a far away pH‚ then we need to focus in the test and nothing else. It would be the same for iron‚ copper turbidity etc. What my data is saying is saying is for test A‚ the pH was bad. There were no nitrates. The acme water had copper‚ the distilled water had none. Same with iron. Acme had tons‚ distilled water had none. Acme water had many suspended particles for turbidity‚ distilled water was clear. The acme water smelt acidic. I can conclude on that the test A for acme water was not
