    "body_text": "Tufts expanded candidate Bacillus spore anchors from 12 to 33. One PET-enzyme fusion showed four times the assay activity, while another worked better on actual PET. Because durable spores can germinate, the team proposed deleting five required genes. Industrial scale and environmental safety remain unproven.",
