the researchers though of finding ways in utilizing guava in making home made soap that can substitute commercial soap. Instead of buying anti-bacterial commercial soap we can use home made guava soap. The guava was chosen as a substitute ingredient for anti-bacterial commercial soap because it is cheaper not like the commercial anti-bacterial soap. Guava can just gather in the backyard and it is easy to make. OBJECTIVES: General Objective

Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures. Maydelis Perez PI 4593042 Florida International University BSC 1010L‚ section UO9‚ March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release

Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin binding proteins (PBPs); which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls‚ thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.Gentamicin is ineffective against anaerobic bacteria because its transport across bacterial cell membranes

few micrometres in length‚ bacteria have a wide range of shapes‚ ranging from spheres to rods and spirals. Bacteria display a wide diversity of shapes and sizes‚ called morphologies. Bacterial cells are about one tenth the size of eukaryotic cells and are typically 0.5–5.0 micrometres in length. Intracellular structures: The bacterial cell is surrounded by a lipid membrane‚ or cell membrane‚ which encloses the contents of the cell and acts as a barrier to hold nutrients‚ proteins and other essential

The characterisation of the bacterial flora of raw frozen cultured seafood was performed to determine a naturally occurring bacterial indicator of antimicrobial resistance in seafood (Paper I). Fresh seafood is processed to produce retailed raw frozen cultured seafood for consumers. The extent to which the microflora of raw frozen cultured seafood differ from the microflora of harvested seafood is not clear. However‚ different bacterial species have been isolated from fish-processing environments

Aerobic and Anaerobic Biodegradation This document provides an in‐depth explanation‚ detailing the processes of aerobic and anaerobic biodegradation. It is intended for general audiences and will provide the reader with the necessary information to understand what is happening during the biodegradation process. For those interested in the biochemical processes of the microbial organisms this document will provide a high level explanation of the aerobic and anaerobic processes. Biodegradation

Plasmids can be removed from the host cell in the process of curing. Curing may occur spontaneously or may be induced by treatments such as ultraviolet light. Certain plasmids‚ called episomes‚ may be integrated into the bacterial chromosome. Others contain genes for certain types of pili and are able to transfer copies of themselves to other bacteria. Such plasmids are referred to as conjugative plasmids. 5. Plasmids usually contain non-essential

Corneal Ulcer has many different names‚ depending on the microorganism that causes the ulcer. Some of the major diseases include Bacterial Keratitis‚ Fungal Keratitis‚ Acanthamoeba Keratitis‚ and Herpes Simplex Keratitis. Bacteria‚ fungi‚ amoebae‚ and viruses are the prime cause for these diseases. These microorganisms settle in the cornea‚ grow‚ and feed on the cornea. This process

lot of peptidoglycan by gram staining. Testing this could be done by using a Petri dish full of agar and testing different bacteria on it to see if the bacteria obtained is gram positive or gram negative. My hypothesis is there will be a lot of bacterial growth on all of the plate. Materials and Methods -Petri dish containing nutrient agar -Cotton swabs -Sharpie A Petri plate containing nutrient agar was used in the experiment. A sharpie was used to section off four quadrants of the dish for
