products (cheese , yoghurt etc..). In fact, they inhibit these microbes up to 5 orders of magnitude at refrigerator temperatures (6oC) without changing the quality of the food. The bacterial mixture is effective against some yeasts, molds, and gram-negative bacteria, but not other gram-positive bacteria. During the tests on the inhibition activities of Propionibacterium sp., cell-free supernatants containing the organic acid molecules that are products of fermentation were not as effective in…

called Gram-positive bacteria. On the other hand, the dye is washed away from bacteria with thinner cell walls, and these are considered Gram-negative. The latter do not become colorless, but pink when counterstained with safranin. Part 3: When to Apply Gram Staining Gram staining procedure is used to determine if bacteria are Gram-positive or Gram-negative. This is usually the first step in the process of identifying bacteria that are present in cultures. This procedure is important in giving a…

1.Introduction: Background/Aim. 1.1 Nature of the microorganism: Enterococcus faecalis was placed under group D streptococci because of similar lysis characters; Identified as Gram positive, non-motile, anaerobic fermentative, lactic acid bacteria; are commensal inhabitant of intestinal bacteria and opportunistic pathogens. They occur singly or in pairs or chains. 1.2 Economic importance: Enterococcus faecalis is also used as a probiotic for production of Mediterranean cheese and meat products…

Listeria monocytogenes is a gram-positive rod-shaped bacterium and facultative anaerobic that can grow under either anaerobic or aerobic conditions but do not form endospores. Among the six species of Listeria, only Listeria monocytogenes is the major human pathogen that causes disease in humans. It is a causative agent to cause listeriosis, a serious infection caused by ingesting the food contaminated with Listeria. The optimum temperature for growth is 30 to 37 degree Celsius, within this…

Bacterium Inoculums preparations for the MIC and MBC experiments From the previous isolated and identified MRSA and VRSA S. aureus isolates, four MRSA+VRSA and four MRSA+VSSA isolates were chosen for MIC and MBC experiments. With a sterile loop, a loopfull from each chosen isolate was inoculated from the BHI slant into MH broth then incubated with shaking at 37°C overnight for 24 hours. The concentrations of these suspensions were adjusted to be equal to the 0.5 McFarland standards by adding a…

used to determine the chemical make up of the cell wall of bacteria. The cell wall can stain either positive or negative, depending on its chemistry.The aim of this experiment. Gram staining was the first differential technique used and still in use to make microscopic vision of bacteria clearer while also sub-divides the bacteria into two major groups: Gram-positive and Gram –negative. This experiment should help us describe how Gram staining affects the different cell walls of the different…

the cell is susceptible to lysis and osmotic rupture due to osmotic rupture due to turgor pressure. Figure 1: Comparison between gram-positive bacterial cell walls and gram-negative bacterial cell walls. Structural differences in the bacterial cell walls cause bacteria to be subcategorized into gram-positive and gram-negative. Gram-positive cell walls (e.g. Bacillus subtilis, Streptococcus…

lead this debate to be push moral deliberation about the rights into the center even where a legal right is recognized. The basis and scope of the moral right to health care involve with positive and negative rights. According to Daniels, “a right to health care is a positive right as opposed to negative right” (Daniels). Furthermore, a right…

slant and if negative it will be a darker red color. The LIA tube will also be used to test decarboxylate lysine, which will help us distinguish bacteria that will produce hydrogen sulfide from those who cannot. If positive for decarboxylate lysine it will have a purple butt, and if negative it will have a yellow butt. The Sulfide Indole Motility (SIM) blue cap tube is a semisolid agar and it is also used to determine sulfide production, indole formation and motility in Gram negative bacteria.…
