During the early years‚ the old milk was left in exposed air and was allowed to age.[2] However‚ as the usage of biotechnology advanced the ideal method of cheese making was also modified. New curdling agents were introduced to “aging” milk such as Lactobacillus which is commonly found in natural products like buttermilk. The introduction of curdling agent showed the importance and the key factor for more efficient and effective manner. In the modern day world‚ the production of Cheese has become more

At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and
