Biology & Agronomy
Cultivated using methods similar to those used with
Porphyra.
|
Chemistry
Studies of Monostroma chemistry are in an active phase partly
because of the reputed bioactivity of some compounds that are
synthesised by the genus.
|
Processing
We have several monographs in progress covering analytical
procedures post-harvest treatment and process technology. Check
the processing
index for available web pages and monographs.

Products, Uses & Applications
Plants generally identified as Monostroma nitidum are
cultivated in Okinawa, Japan (Kagoshima), Taiwan China and
elsewhere. The most common use is as human food. Monostroma
may be chopped and made into sheets in the manner used for
Porphyra.
Monostroma spp. are also reputed to contain bioactive
substances that are useful in topical skin treatments and may have
some pharmaceutical applications related to healing of muscle
tissue. |
