Bacillus‚ Mycoplasma‚ and Escherichia In a clinical setting signs and symptoms can lead a care taker down a treatment path‚ but if a bacterial infection is suspected‚ a definitive answer from the “lab” is needed before prescribing medications. In this instance a yellow sputum was produced by the patient‚ which will be taken to the lab an analyzed under a microscope. There are three suspect bacteria‚ which are Bacillus‚ Mycoplasma‚ and Escherichia. A discussion of staining procedures‚ as well as

The Figure 4.20 shows the profile growth of Escherichia coli type K-12 which was cultured in 20 g/L of glycerol treated with supplements from a carbon source under anaerobic condition and the medium supplemented with 10 g/L of trypton. About 10% working volume of inoculums were added to the medium for the profile growth process. The effects on growth curves of strains of Escherichia coli were investigated by measuring the concentration of succinic acid produced and its optical density by using HPLC

but then over time it should increase more rapidly throughout what is called the log phase. This predictable pattern of growth can be called the organism’s biotic potation. Procedure During this exercise the population growth of the bacteria Escherichia coli (E.coli) will be measured. If the conditions are right‚ the E.coli population will grow more rapidly the longer it stays in that area. Turbidity‚ meaning cloudiness‚ will be how the tubes are measured to give the results of bacterial growth
