| + | |
- | <hr />
| + | |
- | <p>Our researchers mainly face regular bio-safety challenges in a
| + | |
- | molecular microbiology lab, such as risks staining DNA agarose gel with
| + | |
- | EB, extracting RNA from organisms with TRIZOL, and manipulating with
| + | |
- | DEPC treated water, etc. Any researchers conducting such experiment<img
| + | |
- | src="https://static.igem.org/mediawiki/2011/4/42/ZJUsafety2.jpg" width="300"
| + | |
- | style="float: right;" /> are instructed about the right method both by
| + | |
- | printed protocols and BIG BROTHER in the lab (XD). After the training,
| + | |
- | we must pass an on-line test about the lab safety, standard experiment
| + | |
- | procedure and lab waste treatment. During any experiments, necessary
| + | |
- | individual protections such as gloves and white robes are always
| + | |
- | required. Also, the public safety of the lab is guaranteed by the strict
| + | |
- | registering protocols on the operation of any apparatus. In order to
| + | |
- | make sure all the requirements above were followed well by the
| + | |
- | researchers and to get prepared for any emergency, our lab (also is the
| + | |
- | open bio-lab of the college) set up 24hr*7 camera system in the room.</p>

| + | |
- | <hr />
| + | |
- | <p>First we picked DH5α and JM109 as the two strains to manipulate
| + | |
- | in our research. These are two non-pathogenic E. coli strain and do not
| + | |
- | pose problems to the public health. The bio-parts we utilized are all
| + | |
- | security ensured, coding for florescence protein, cellulose degradation
| + | |
- | enzymes and metal ion binding proteins. Although bio-film formation is
| + | |
- | closely related to pathogenicity, our experiment enhances bio-film
| + | |
- | formation only by changing the external environment factors instead of
| + | |
- | modifying the inherited nature of the bacteria. This is an important
| + | |
- | measure to assure that the bacteria do not acquire previously
| + | |
- | non-existing pathogenic capacity.</p>

| + | |
- | <h1>Environment safety</h1>
| + | |
- | <hr />
| + | |
- | <p>The experiments conducted in our lab are with intensive concern
| + | |
- | of environmental impact. No media containing engineered germs go into
| + | |
- | the sewer before sterilization. Besides, all the utensil contacted with
| + | |
- | the engineered bacteria must first undergo sterilization then be washed.
| + | |
- | During our research we have used antibiotic resistant plasmids,
| + | |
- | including chloramphenicol, kanamycin, ampicillin. Though risks of the
| + | |
- | practices exist, we believe that it's possible for us to use them safely
| + | |
- | with the mature protocols and techniques. For the toxic and hazardous
| + | |
- | chemicals, they are collected and treated properly. The acid and basic
| + | |
- | chemicals are neutralized and pour into the swer.</p>

| + | |
- | width="220" style="float: left;">Our biobricks includes two new
| + | |
- | promoters responded to oxygen concentration, hence the regulation of the
| + | |
- | devices would not involve potentially bio-hazard chemicals. Also as
| + | |
- | partially described above, our parts express proteins aiming at binding
| + | |
- | of metal ions, degradation of cellulose, and the localization by
| + | |
- | fluorescent proteins. All of these products are not bio-hazard, and the
| + | |
- | expression is under fine control.</p>
