reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria will exhibit a faster rate of reduction in nitrate levels. OBJECTIVE:- To denitrify nitrogen (Nitrate and nitrite) rich water.

ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of mobility somehow. Since a biofilm is just one huge community of bacteria‚ it would be good to find out if there are ones that are more

Microorganisms: * Small living organisms; there are 3 types * Bacteria – ecoli‚ salmonella * Fungi – mushrooms‚ athletes foot * Virus – influenza (flu)‚ HIV * When they enter our body‚ they multiply and release toxins / harmful chemicals into our blood * They duplicate every 20 minutes * Physical barriers: eyelashes prevent MO’s from entering through our eyes‚ nasal hairs reduce them‚ skin is a barrier to them (although they can enter through cuts)‚ chemicals in tears

Conclusion In part A of this experiment‚ we transformed the bacteria into an antibiotic resistant form by inserting a plasmid into it. We used heat shock in order to make the bacteria capable to uptake a plasmid in the presence of calcium ions that help disrupt the cell membrane (heat shock is the combination of altering hot and cold). When they are capable of accepting plasmids‚ the bacteria are incubated with plasmids that carry the resistance to a particular antibiotic‚ in this case ampicilin

Abstract: This lab works to develop the understanding of bacterial transformation through the integration of a plasmid into E-coli bacteria. Understanding of plasmids‚ GFP‚ expression of genes and bacterial candidates is used to formulate a lab which demonstrates a variety of factors associated with transformation efficiency. It was deduced that there are certain requirements present in the pGLO plasmid for full gene expression and that an increase in transformation solution positively impacts

Presence of nitrogen fixing Klebsiella pneumoniae in the gut of the Formosan subterranean termite (Coptotermes formosanus) (p3297) A Review by: Mark Edge (Faith & Jaelen Love You) Because the Formosan termite is an economically important pest. Researchers are concentrating efforts on understanding the details of their physiology. Before the late 80’s early 90’s not much physiological research was concentrated toward any one species of termite outside of general physical characteristic‚ anatomy

into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes (fungi‚ mosses‚ ferns‚ gymnosperms and angiosperms) were included under ‘Plants’. It is based on the presence of cell wall. But prokaryotes and eukaryotes are widely differed in other characteristics. It included

Yesinia Pestis Yesinia Pestis is the bacteria that caused the Bubonic Plague in 1347 and marched across Europe killing many people. This bacterium can grow with or without oxygen making its expansion inevitable. Yesinia Pestis is able to survive for several months in cool‚ moist places like rodent holes. People in the United States can be infected by Yesinia Pestis each year from flea or rodent bites‚ it is estimated that 10 to 20 people are infected yearly. Bacteria transmission occurs in one or in
