Next‚ an oxidase test was performed to eliminate one or more of the bacterium choices. P. aeruginosa was eliminated as the identity of the bacterium when the oxidase test results were negative. An EMB plate of the bacteria was examined to identify whether the bacterium was S. typhi or E. coli. The growth on the EMB plate was shiny and metallic

Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletiondue to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems. Indoor

confirm these results‚ since it has the ability to select for gram negative bacteria (Figure 9). With negative results for this test‚ a variety of bacteria were able to be eliminated from the list of bacteria‚ including Staphylococcus aureus‚ Pseudomonas aeruginosa‚ and Enterobacter aerogenes. The EMB test (Figure 10)‚ helped to further eliminate more bacteria including E. Coli. This confirmed our results along with the negative results for the Indole test and the Sulfur reduction test (Figure 6). What

The biopolymer PHB is produced by placing bacteria‚ such as Alcaligenes Eutrophus and Pseudomonas‚ in a suitable growth medium e.g. molasses from agricultural waste and fed high levels of nutrients such as glucose‚ causing it to multiply rapidly. Nitrogen is then

A Pseudomonas species‚ isolated from the crop of H. midae‚ has been selected for further study due to its high extracellular alginolytic activity. You are assigned the task of establishing a gene bank of this Pseudomonas species in E. coli. Describe‚ with the aid of a flow diagram‚ how you would accomplish this task.

Is there a significant difference in the antibacterial properties of the plant extract on Pseudomonas and Escherichia Coli as shown by the zone of inhibition? 3. Does the stickcane shoots extract exhibit antibacterial property? Significance of the Study The result of this study can be beneficial to the community. It can motivate the mass production

Introduction Many systemic diseases has been associated with poor oral health; among them‚ respiratory infections in elderly persons. With increasing age‚ many elderly adults suffer a decline in physical‚ psychological and mental abilities which may necessitate admission into full-time care (De Visschere‚ de Baat‚ Schols‚ Deschepper‚ & Vanobbergen‚ 2011). As frailty increases‚ the elderly is less able to care for themselves which may lead to a decline oral health‚ which‚ in turn‚ is recognised as

ANTI-INFECTIVES Anti-infective agents are drugs that are designed to act selectively on foreign organisms that have invaded and infected the body of a human host. Ideally‚ these drugs would be toxic to the infecting organisms only and would have no effect on the host (or human) cells. OVERVIEW • Antimicrobial therapy (often termed “antibiotic therapy”) is the use of medications to treat infections caused by bacteria‚ viruses‚ and fungi. • Antimicrobial must use selective toxicity to kill
