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.

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

1.4.1. Safety Aspects of Probiotics Today‚ there are evidences that probiotic strains used as commercial bacteria are safe to use in applications. The safety of the probiotic products is appraised with the phenotypic and genotypic characteristics and the statistics of used microorganisms (Çakır 2003). Safety aspects of probiotic bacteria include the following requirements. 1. Strains for human use are preferred to be human origin. 2. They are isolated from healthy human gastrointestinal tract. 3

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

The substance used in antisepsis is called an antiseptic‚ which is used to kill a broad range of infections. An antiseptic is different from an antibiotic‚ which is used to target a certain type of bacteria. Once scientists and surgeons learned more about bacteria and the connection between bacteria and infection‚ they developed ways to prevent the latter. Antiseptics are applied to the skin to reduce the possibility of infection. Common antiseptics include rubbing alcohol‚ boric acid‚ hydrogen
