price‚ and high degree of reduction have made glycerol a highly attractive and exploited carbon source for the production of fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis. The kinetics of glycerol fermentation

by the emergence of Shiga toxin-producing Escherichia coli (Callaway et al.‚ 2013). Specifically‚ Shiga toxin-producing E. coli O157 is a foodborne pathogen of significant public health importance. It can cause mild to bloody diarrhea in humans which may progress to hemolytic uremic syndrome (Centers for Disease Control and Prevention‚ 1993; Hussein‚ 2007) that can be fatal in children‚ the elderly and immunocompromised individuals. E. coli O157 is also responsible for an estimated 63‚153 illnesses

Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes. To elaborate on how this altered bacteria works

MULTI-STATE INFECTION Multi- State Escherichia coli O26 Infection Linked to Raw Clover Sprouts Escherichia coli are gram- negative bacteria that are normally found within the gut of warm bloodied organisms. There are several strains of E. coli that exist as part of the normal flora of the human digestive system. They prevent harmful bacteria from establishing themselves in the intestines‚ and they also aide in the production of vitamin K2. Most E. coli strains are not harmful to humans‚ except

Research Question: E. coli strain MM294 is placed under different sound frequencies. Does sound frequency affect the growth of E. coli strain MM294? Background: Noise pollution is a problem in urban areas and can be the cause of several health issues and increase risks of disease. It is interesting that even something inanimate like sound could affect so much of biological processes. The movement of energy through matter produces sound. Sound is a mechanical wave that travels

The Effect of Acetyltransferases on 2 different strains of E. coli Introduction Scientists have recently discovered that resistance to antibiotics may not be such a new thing. Evidence of bacteria samples in Canadian permafrost proposes that these resistances have been around for at least 30‚000 years (Luiggi 2011). In our required pre-lab reading‚ we learned tuberculosis is becoming increasingly drug-resistant‚ giving proof that bacteria can adapt to necessary changes in order to survive (Barry

Isolation of plasmid DNA and analysis of isolated plasmid Introduction: A plasmid is an autonomously replicating extra-chromosomal genetic element. In other words‚ this is a DNA molecule external to the bacterial chromosome that is able to replicate on its own and distribute its daughter molecules to daughter cells. You have successfully cloned a fragment of chromosomal DNA containing a tetracycline resistance cassette into a plasmid (pET11a). To this end you have (1) isolated total chromosomal

introduce the gene‚ usually a plasmid or bacteriophage‚ is called the vector. Ideal vectors have high rates of replication. Gene cloning is an important procedure in genetic engineering that allows us to produce a large amount of a useful gene product: for instance‚ insulin can be made for diabetic individuals by cloning genes from pancreatic cells.(Wikipedia 15/11/2014) Cloning vector: A cloning vector is a small piece of DNA‚ taken from a virus‚ a plasmid‚ or the cell of a higher organism‚ that can
