Once the GMF appear in every single supermarket‚ do you know what exactly you are going to eat? GMF means genetically modified foods. The genetically modified foods are initially born in U.S. in 1983. About thirty years before‚ people use the original seeds or sprouts to grow their fruits and vegetables. However‚ as the well development of the genetically modified foods‚ the natural foods are gradually replaced in nowadays society. And as the genetically modified foods starts gain its popularity

California based genetic foods producer Calgene Inc. has been chosen as the subject for the case analysis. The company‚ which is now part of Monsanto‚ introduced genetically modified tomatoes in the year 1992 called the “Flavr Savr Tomato”. This case analysis uses the Langenderfer & Rockness’ Seven Stage Framework to analyse the ethical decisions taken by the company. Stage 1: What are the facts of the case? Calgene Inc. has invested $20 million in producing genetically modified (GM) tomatoes

Our analysis of drought indices focuses on the five crops with the broadest geographic distribution and highest production in the U.S.: barley‚ corn‚ cotton‚ soybean and winter wheat (Figure 1). Data on crop production for each county are collected by the United States Department of Agriculture (USDA) and made available by the National Agricultural Statistics Service (https://quickstats.nass.usda.gov). Only crop statistics under non-irrigated conditions were considered in this study. We created five

In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

1- Synthesis of silver nanoparticles by Bacillus sp.: The microorganisms in the most contaminated toilet Sink were isolated by dilution technique. The dominant bacterial strains are identified as Bacillus sp.‚ on the basis of morphological and biochemical characteristics. Gram’s staining: Gram positive and rod shape. They were serially diluted and spread on nutrient agar plates. The starch has been hydrolyzed and a clear zone by the addition of iodine solution. Visual identification: When bacterial

and bacteria that retain the color from the primary stain is called gram-positive. Bacteria stain differently because of chemical and physical differences in the cell wall. Procedure For this lab we used three cultures; Escherichia Coli‚ Bacillus Subtilis‚ and Staphylococcus Epidermidis. Using a different slide for each sample we started by preparing and fixing each slide. Next we covered the slide with crystal violet for 30 seconds then rinsed with water. Next we covered the slide with Grams

The steaks that were done on this plate seemed to show that E. coli did not have lipases because it did not have clear zones. Staphylococcus aureus seemed to have these clear zones meaning it can secrete lipases. The bacteria Bacillus subtilis did not grow well to see if there was a clearing. After doing some research‚ it was shown that B. subtilis is lipase positive so there should have also been some clear sones like the Staphylococcus aureus (Watson). The DNAse agar could not
