             <p> According to the toxic effect of these compounds on human health, animal health and the environment, a quantitative criterion for clear toxicity scores was created using a scale from 1 to 5 and a “traffic light” colour scheme. If the reviewed information showed that the secondary metabolite did not affect in a negative manner any of the three parameters, it was considered non-toxic and categorised as a “1” (green). If the data showed that the compound exhibited some degree of toxicity but nothing considerably serious or untreatable, it was considered slightly to moderately toxic and scored as a “3” (yellow). And if it showed that the secondary metabolite was extremely toxic, it was considered as highly toxic and classified as a “5” (red). However, considering there were three parameters to be contemplated, combinations of those three scores could occur (e.g., a secondary metabolite being considered non-toxic for humans but slightly to moderately toxic to animals). Therefore, if a compound was non-toxic according to one  parameter and slightly to moderately toxic for the others, it was categorised as a “2” (green-yellow). On the other hand, if it was slightly to moderately toxic according to some parameter and highly toxic for others, it was classified as a “4” (yellow-red).  Finally, if the secondary metabolite had no documented toxicity information, or if there was no specific BGC  and just the general class of secondary metabolite or microorganism,  the compound was categorised as “?” (black) with the note to consider if, according to the precautionary principle , one should prusue with the use of the given microorganism in the laboratory.

Human Practices

Summary

Our project encompasses the characterisation of standardized biological parts that facilitate the use of non-model microorganisms as novel chassis. The domestication of non-model strains with high potential for industrial applications could accelerate their understanding and increase the list of strains that are suitable for bioproduction of relevant products (Check out the team’s essay “Masses of Chassis” for more information).

Essay

However, we recognise that the integration of uncommon or new strains into the laboratory raises both biosafety and biosecurity questions (e.g. unknown pathogenicity and toxicity), which are heightened by the fast development of SynBIo and DIYBio fields. Such issues, if not properly addressed, can constitute a risk for both users and their surroundings (i.e. unwanted health and environmental problems).

In order to contribute to current risk assessment procedures, and as a precautionary step for both experienced and non-experienced users, the Edinburgh OG team has worked on an accessible, easy-to-use program to evaluate the toxicity of curated secondary metabolites of both model and non-model organisms.

In the Silver section, the biosafety and biosecurity issues regarding our project are exposed along the description of current risk assessment practice.

In the Gold section, our “CARE” program is presented along with its characteristics, feedback from other iGEM teams, limitations and further improvements.

Finally, in the Integrated Human Practices section, the main characteristics of the human practices’ of our project are highlighted.
