The enzymes of our bacteria were foreign genes from the bacterial species of <i>Clostridium</i>, <i>Haemophilus</i>, <i>Mycobacterium</i>, <i>Prochlorococcus</i> and <i>Bacillus</i> but these extracted genes expressing enzymes for intermediates didn't contain any pathogen risks. Since these genes weren't available as BioBricks we ordered them synthethised. The gene synthesis companies are constantly Blasting the ordered gene sequences with the pathogenic ones so the shipping isn’t preceded if hazardous material is found.</br></br></p> |

They had also received mandatory training on how to work safely in the laboratory as a part of their studies. Some of the topics of this training include personal protective equipment, how to work with different chemicals and GMOs and dispose of them, how to mark reagents, and training on safety labels, biosafety levels, most common lab accidents and how to avoid them, different types of hoods, the importance of proper planning and cleaning up after oneself.</br></br> |
Additionally, we had a lab safety lecture held by an instructor specifically about the lab we worked in, covering similar topics (PPE, waste disposal etc.). All of our team members who worked in the lab took part to this lecture and the following round in the lab spaces. Furthermore, the location of first aid kits, fire extinguishers and emergency showers in the laboratory were shown to us by an instructor. None of our team members were allowed to be alone in the lab and work during nights or weekends always needed a permission from the lab personnel.</br></br> | Additionally, we had a lab safety lecture held by an instructor specifically about the lab we worked in, covering similar topics (PPE, waste disposal etc.).

The lower flammability limit is 1,8 % and upper 8,4 % of air volume based on a <a href="https://www.airgas.com/msds/001045.pdf" target="_blank">material safety data sheet</a> (MSDS). In an earlier |
+ | <a href="http://www.nature.com/ncomms/2014/140902/ncomms5731/pdf/ncomms5731.pdf" target="_blank">study</a>, the maximum produced propane yield without extra oxygen addition was 0.5 mg/L which can be considered to be below flammable concentration. Still, the accumulation of propane was prevented with proper ventilation during the cultivation processes for GC-analysis and continuous production. MSDS must be read before handling the strain producing propane, as we did before starting propane experiments. | ||

Consumers should not handle cylinder's valve if it is not connected to any device using propane as a fuel. Consequently, propane would not be straight released from the container into surroundings to cause a flammability risk. </br></br> |
