| I have always had a passion for sciences, particularly chemistry, and hope to pursue a joint concentration in Molecular and Cellular Biology and Economics. Eventually, I plan to apply for an MD/PhD program and specialize in digestive disorders.

| <b> Latest news: </b><br>
| |
| I'll be making a presentation at the next iGEM meeting on engineering <i>E.coli</i> to efficiently produce EtOH as well as adaptamers (past studies of, and potential applications of). Adaptamers haven't been at the forefront of discussion lately, but they're great for labs of the iGEM size, and have an array of potential uses. <br>

| Perhaps one of the oldest papers, but also one of the best in terms of examining the basic engineering concepts that the other papers seem to take for granted.

| Looks intriguing. Again, relatively old, but I think it will emphasize basic manipulations that have been experimentally performed - which is good if we plan to look into this. I haven't read this one fully yet, but I'll update if I do. <br><br>

| Two major results should be emphasized: yeast consistently produced EtOH more rapidly; commericial enzymes (alpha-amylase and pectinase) enhanced EtOH yields in both yeast and e.coli. As a side note, I'm finding it interesting that most of the newer articles (such as this one) seem to advocate using engineered yeast rather than e.coli, while many earlier studies (early 1990s) seemed to find that E. coli were equally, or more, efficient. I'll keep an eye out for this trend as I continue reading. <br>

| <br> This paper isn't as mechanism-based as the Aristou paper (cited below), but provides a nice overview of the history of ethanol use, why energy is a concern, etc. It seems to be a nice background for the general public, and provides a nice introduction to the field.

| <br> This review focuses on the bioconversion of the pentose fractions into ethanol and suggests use of biocatalysts (such as bacteria and yeast) to assist in this slow-step in the conversion of sugars into useful products.

| A really great overview of some potential applications of biosensors, including electrochemical sensors, detergent sensors, acid rain sensors, red tide, cyanide sensors, E. coli used for gas toxicity monitoring (see reference 276 of the paper - I intend to look into this more), and food sensors to detect glucose, sucrose, and lactose.
