accounted by the slow movement of molecules that decreases enzyme and substrate collision. The difference in optimal temperature between the fungal and bacterial amylase may be due to the different environments that each enzyme is naturally found in. Bacillus licheniformis is found in a wider range of environments so its enzymes have to survive a higher range of temperatures. Where as Aspergillus oryzae is found in lower temperature habitats preventing its enzymes from tolerating a wider range of temperatures

Several cells majority Bacillus and cocci cells. D. Were there observable differences between your fresh yogurt slide and the prepared yogurt slide? If so‚ describe them. Only perhaps that there was far more Cocci cells then Bacillus E. Describe the four main bacterial shapes 1. Cocci - Spherical or oval bacteria having one of several distinct arrangements based on their planes of division 2. Bacillus - Rod shaped bacteria. Bacilli all divide in one plane producing a bacillus‚ streptobacillus

Gel filtration chromatography on Sephadex G-50 The crude broth obtained after fermentation was subjected to ammonium sulphate precipitation at 70% (w/v). The pellet so obtained was resuspended in cold saline (2 ml) and dialysed. The dialysed enzyme was loaded onto a column of Sephadex G-50 (120 cm × 1.0 cm) equilibrated with 10 mM Tris-HCl buffer‚ pH 8. The column was eluted at a flow rate of 1 ml / 6 min. The elution profile of gel filtration chromatography is shown in the (Fig: 1). The fractions

a good bioterrorism agent. How is Anthrax Caused? Anthrax is caused by the bacterium[2] ‘Bacillus anthracis’ that is highly lethal in its virulent form. Anthrax most commonly occurs in wild and domestic animals‚ but it can also occur in humans when they are exposed to infected animals‚ tissue from infected animals‚ or high concentrations of anthrax spores.[3] Bacillus Anthracis Bacillus anthracis‚ the bacterium which causes anthrax‚ is rod-shaped and about 1 by 6 micrometres in size

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While

Table 4 showed antibacterial zone of inhibition of CMZH I-III and CZH against gram-positive bacteria Bacillus cereus and Lysinibacillus fusiformis and gram-negative bacteria Escherichia coli XL1B. It was observed that the antibacterial inhibition zone increased from CMZH I to CMZH III against all three bacterial strain where OMMT content has been increased

Hydrolysis Report Bile Esculin Hydrolysis‚ Starch Hydrolysis‚ UreaHydrolysis‚ Casein Hydrolysis Hydrolysis Report Introduction Hydrolysis is a chemical reaction that uses water to split complex molecules. The water molecule H2O is split in the mechanism of hydrolysis‚ hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell‚ it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell‚ it

Anthrax is a lethal disease that is caused by gram-positive‚ rod-shaped bacteria known as Bacillus anthracis. Many researchers believe that this disease originated in Egypt and Mesopotamia in 1250 BC. However‚ there were also other regions during this time period who were acquainted with anthrax‚ such as Ancient Greece and Rome. Many illustrations and ancient writings by famous scholars of those times depicted this disease. For example‚ the author Homer illustrated anthrax in his poem Illiad from

Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and
