What patents cover production and use of bacterial histamine (and how to search for them on Google Patents)
If you’re looking for patents related to “bacterial histamine” (histamine made by microbes, microbial production strains/processes, or uses of histamine generated in situ), the most effective approach on Google Patents is to search both the product name and the biology/process terms that patent examiners expect.
On Google Patents, try combining keywords like:
- “histamine” with “bacteria” / “microorganism” / “microbial”
- “histidine decarboxylase” (the enzyme many histamine-producing bacteria use)
- “biogenic amine” (histamine is a biogenic amine)
- “decarboxylation” / “fermentation” / “production” / “process”
- “histamine producing” plus organism names you suspect (e.g., “Morganella”, “Hafnia”, “Enterococcus”, “Lactobacillus”, depending on context)
You can also filter by:
- Assignee (companies or universities)
- Patent kind (grants vs applications)
- Publication date range
- International classification codes (IPC/CPC) once you find a few good seed patents
This typically surfaces patents covering either (a) making histamine via fermentation or engineered organisms, or (b) handling/preventing histamine production in foods and industrial processes where histamine-forming bacteria are a quality/safety problem.
Are patents usually about making histamine for sale, or about stopping “bad” bacterial histamine in food?
Patents mentioning bacterial histamine often fall into two very different buckets:
1) Production-use patents
These focus on methods to produce histamine (or histamine derivatives) using microbes or microbial enzymes, and then downstream uses (e.g., chemical synthesis intermediates or biological uses).
2) Prevention/control patents
These focus on reducing histamine formed by bacteria in food, fermentation, fish/seafood, or other materials. In that context, “bacterial histamine” is a spoilage/toxicity issue, so patents cover inhibitors, processing controls, detection, or enzyme disruption to prevent histidine decarboxylation.
Google Patents searches for “histamine” plus “biogenic amines” often skew toward the prevention/control cluster because histamine is a regulated food safety concern in many jurisdictions.
What specific biological/process terms usually appear in relevant patents?
Patents about bacterial histamine production commonly reference the mechanism bacteria use to form histamine from histidine:
- Histidine decarboxylase (often abbreviated “HDC” in some patent text)
- Conditions that affect decarboxylation (pH, temperature, oxygen, salt, maturation/aging time in fermentations)
- Strain selection or enrichment (for production) or suppression/elimination (for prevention)
- Fermentation parameters and media composition
If you search only “histamine” you will get broad results; adding “histidine decarboxylase” and “biogenic amine” narrows toward the bacterial production mechanism patents.
What are the main use-cases patents attach to histamine made by bacteria?
Depending on the assignee and claim scope, “histamine” produced/connected to bacteria shows up in patents for:
- Food and beverage safety: limiting histamine formation in fermented or stored foods
- Quality control: detecting histamine levels or monitoring microbial activity that predicts histamine formation
- Industrial bioprocessing: using enzymes/microbes to convert substrates via histidine decarboxylation
- Downstream chemical/biological applications of histamine or derivatives (less common than the food-safety/control angle, but present)
To find the right “use” cluster on Google Patents, include one more keyword from the suspected domain (food, fish, fermentation, detection, inhibitor, enzyme, diagnostic, or chemical synthesis).
How do you tell if a patent is about bacterial histamine production vs bacterial histamine contamination?
In the claim language, these cues help:
- “produce” / “obtain” / “ferment” / “biocatalyst” often points to production.
- “prevent” / “inhibit” / “reduce” / “control” / “determine” / “monitor” often points to contamination/spoilage control.
- “histidine decarboxylase activity” as a target is common in both, but context differs: production patents may optimize conditions to increase it; prevention patents aim to suppress it.
If you open a promising Google Patents hit, check the “Abstract” and the first independent claim for whether the goal is generation or inhibition.
What if you meant “histamine produced by bacteria” in food specifically?
If your intent is specifically about histamine-forming bacteria in foods (a very common search pattern), the most relevant related patent topics tend to be:
- Methods to detect histamine (including rapid assays)
- Processing steps that reduce histidine decarboxylase activity or histamine accumulation
- Starter cultures or preservation strategies to suppress histamine-formers
- Chemical/biological inhibitors (e.g., targeting decarboxylation or the organisms that carry it)
Using food-oriented terms alongside “histamine” and “biogenic amines” usually improves results.
What I need from you to pinpoint exact patents (instead of generic search guidance)
“Patents google com us production and use of bacterial histamine” is broad. Share one of the following so I can identify the most likely patent set and exact query terms:
1) Is this about food safety (fish/fermented foods), or about producing histamine as a product?
2) Any organism you care about (e.g., Morganella/Hafnia/Enterococcus/Lactobacillus) or any enzyme (histidine decarboxylase)?
3) Your target country/region (US only, or also EP/WO)?
4) The type of patents you want (detection, inhibitors, strain/fermentation process, or chemical use)?
If you reply with those details, I can propose a tight set of Google Patents search strings tailored to your scenario and the kinds of patents you’ll see.
