blue onto the smear for 30 second‚ rinsed with water‚ blotted dry and observed the slide using oil immersion. Gram Stain For comparison purpose‚ I used two bacteria for this experiment. They are E. coli‚ a gram negative bacteria and Staphylococcus‚ a gram positive bacteria. I prepared a heat fixed smear of both bacteria. First‚ I used crystal violet as my primary stain‚ put few drops of it on the smear and let it sit for 30 seconds.

Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the

Antibiotic Resistant Bacteria A better understanding of the use of antibiotics would help prevent the reality of antibiotic resistant bacteria evolving to the point of human extinction. Antibiotic resistance is a natural process‚ stronger bacteria survive and multiply. Even though antibiotic resistance is a natural process‚ it happens faster when antibiotics are used irresponsibly. Through use of media‚ personal responsibility and research‚ our species could help deter further antibiotic resistance

Determining the Unknown Microorganism from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by

Screening and identification of rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

How is Ghana different from the UK? UK Ghana Flags Red‚ white‚ blue Red‚ green‚ yellow with a green star Climate The climate of Ghana is tropical‚ but temperatures vary with season. We never know what the weather will be like from one day to the other. It can be sunny one day and rainy the next. As we have such a variable climate changing from day to day‚ it is difficult to predict the weather. In general we have warm summers and cool winters

Explain briefly how macroeconomics is different from microeconomics. Please give examples. What is economics? Before we start to learn about economics‚ we have to understand that what is the different between macroeconomics and microeconomics. Macroeconomics and microeconomics are the main branches of economics. (Karl E. Case‚ Ray C. Fair and Sharon M. Oster (2012): Principles of Economics‚ 10th ed. Global Edition‚ Chapter 1). And‚ I will describe that with examples. Microeconomics seems likes
