  "query": "Map a bounded set of patent families concerning microbial fermentation production or recovery of citric acid, with publications from 2018 through 2024. Use original patent publications and official patent-office records where accessible. Group related publications into families and distinguish production-stage claims from recovery-stage claims and description-only examples. Record claim numbers and source URLs. Report legal status only with a dated official source; otherwise mark it unverified. Do not give freedom-to-operate or enforceability conclusions.",
