Objective:
The primary objective of this proposal is to develop and deploy the Python-based EcoGenoRisk, a bioinformatic tool with three aims for the software to deliver:
- Identify those genomes within public databases that negatively respond to the product, display the most similarity genetically to the synbio organism, and/or harbor similar or competing pathways to define susceptible populations;
- Identify environmental habitats that are likely to harbor the susceptible populations; and
- Quantify both the likelihood of the synbio microorganism to arrive in the susceptible habitat and the extent of structural or functional disruption experienced by the resident microbial community.
Progress Summary:
Within the reporting period, the main focus of the initial coding effort has been to develop the HazID portion of EcoGenoRisk. HazID has three main functions under development: NicheOverlap, CompetitorFind, and PoisInhibitor. NicheOverlap focuses on the direct displacement by the synbio microorganism overlapping and outcompeting with a given niche. CompetitorFind identifies similar, competing, or mitigating pathways in response to the presence of the synbio microorganism. Finally, PoisInhibitor finds those enzymes that respond negatively to the product of the synbio microorganism.
The main results in this reporting period are as follows: (1) a script for HazID:NicheOverlap, (2) a genome database, (3) an EC number database, (4) a comparison between genomes within the database, and (5) a test of in silico generated synbio genomes.
Future Activities:
The main future research and development activities planned for the next reporting period continue the tasks identified in the timeline (Figure 1). The development of HazID will conclude with the addition of PoisInhibitor and CompetitorFind. The second milestone will be satisfied with the successful implementation of the script for these two sub routines. After passing this milestone, developmental effort will switch to EcoCen and the curation of metagenomes. The main targeted outputs during this time period are two papers and the attendance of two conferences.
