Cheese: A Home to Bacteria “Cheese is just a means of controlled spoilage‚” said Steve Jenkins‚ a Master Cheesemonger at Fairway Market. (Cheese) Bacteria‚ or starter cultures‚ control the flavor‚ hardness‚ type‚ and many more aspects of cheese. The two main strands of bacteria involved in cheese making are Lactococcus and Lactobacillus‚ which ferment sugars found in the milk. Humans have learned to manipulate bacteria and the fermentation process to produce different types of cheese such as Swiss

the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order to isolate the two different bacteria‚ colonies

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

procedure called gram stain is used in the identification of bacteria. Bacteria can be gram-positive‚ gram-negative‚ or gram-variable. Most bacteria however‚ are usually gram-positive or gram-negative. Gram-positive and gram-negative bacteria react differently to staining because of the differences in their cell walls. Bacterial cell walls contain a polymer called peptidoglycan. Gram-positive bacteria have more of this polymer than gram-negative bacteria. They are also less complex than gram-negative
