of the practical we planted microorganisms on different petri dishes in order to verify if the microorganisms are really everywhere The necessity and value of collecting‚ identifying‚ and analyzing the various microbes regularly encountered in the daily human environment becomes quite apparent .when one gains even a very basic knowledge of how diseases are acquired and spread. The purpose of this lab was to collect and observe microbes from environmental and human body samples by culturing them

done by spreading bacteria on a culture plate and starting a new stock of bacteria from a single colony. Fours characteristics by which colonies can be identified are shape‚ color‚ size and texture. 4-A Petri dish is used as a container for a medium used to grow cultures. Leaving the Petri dish open will increase the probability that your culture will be contaminated. 5- Between each set of streaks you sterilize the inoculating loop in the Bunsen flame. At the beginning of the next streak you

Hypothesis: If three genres of music were played to the same samples of bacteria‚ then the sample with pop music playing to it will have the most growth because pop music has a more positive and upbeat rhythm to it causing the bacteria to grow more. Variables: Control: The petri dish of bacteria without music and the samples of bacteria. Independent Variable: The type of music played to each sample. Dependent Variable: The growth of bacteria in each sample. Constant: The temperature and location‚ volume of music‚ and the time frame music is

The Relation of Antiseptics and Bacteria Growth Purpose: To explore the effectiveness of different levels of concentration of antiseptic and antibacterial products’ prevention of bacterial growth. Question: Amongst common household products‚ which antiseptic and level of concentration is more effective at inhibiting the growth of bacteria? Introduction: Antiseptics are antimicrobial substances used on living tissue to reduce the possibility of infection‚ putrefaction or sepsis. The word “anti”

been slightly different due to us not being able to record the number of cells present on the petri dish clearly. This may have been due to the microscope not having a higher resolution thus affecting the accuracy of the results being obtained. Furthermore‚ the group MRSA also did the same practical but they used pH 2. The results that they obtained were that there were 45 cells present on the petri dish after five days. MRSA also obtained a value of 36000000 per litre. Bacteria grow by binary fission

(introduced) and cultured (grown) in the laboratory for test studies to determine their morphology (the shape‚ size‚ arrangement‚ and internal structures) and pathology (ability to cause disease). Inoculation has to be performed without adding other microbes or contaminants. Aseptic (sterile) technique is the process of growing pure (uncontaminated) cultures‚ and is essential for proper characterization of a bacterium. Aseptic technique includes the use of sterile media and equipment. The sterility

Which microbes are most susceptible versus most resistant to disinfectants? Why?Gram-positive cocci‚ including antibiotic-resistant staphylococci‚ are readily inactivated by disinfectants. Enterococci‚ including vancomycin-resistant strains‚ are also susceptible
