<h1>Researcher safety</h1>
+
-
<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>
+
-
</div>
+
-
<div class="block" id="safety1">
+
-
<h1>Public safety</h1>
+
-
<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>
+
-
</div>
+
-
<div class="block" id="safety1">
+
-
<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>
+

<div class="block" id="safety1">

<h1>Biobrick safety</h1>
+
-
<hr />
+
-
<p><img src="https://static.igem.org/mediawiki/2011/4/46/Zjusafety1.jpg"
+
-
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>
