# Kuehnle AgroSystems

> Kuehnle AgroSystems, Inc. (KAS) is a Honolulu, Hawaii microalgae biotechnology company
> founded in 2007 by Dr. Adelheid "Heidi" Kuehnle, with a second site in Cork, Ireland. KAS
> makes high-value natural products from microalgae — principally natural astaxanthin and
> algal protein — using a patented heterotrophic "dark fermentation" process and proprietary
> non-GMO Hawaiian algal strains that run in standard fermentation equipment instead of open
> ponds or photobioreactors, compressing production from weeks to days. Markets served are
> nutraceuticals, cosmetics and skincare, functional foods and beverages, and aquaculture and
> animal feed. In August 2025 KAS entered a development and commercialization partnership with
> Corbion for an esterified natural astaxanthin.

## Crawler policy

`https://www.kuehnleagro.com/robots.txt` is the Squarespace default, which disallows a long
list of AI crawlers by user agent — including `ClaudeBot`, `anthropic-ai`, `GPTBot`,
`Google-Extended`, `CCBot`, `Amazonbot`, `Bytespider`, `Meta-ExternalAgent` and `cohere-ai` —
while allowing general web crawlers. Agents should honor it.
