Biologically active organic silicon compound and processes for locating algae parts from which algae culture compost can be extracted from and compost extraction from

摘要

Culturing algae from which organosilicon cpds. can be extracted, comprises: (i) removing micro-cuttings from an alga plant; (ii) immersing the cuttings in a tank contg. sea water; (iii) immersing an elongated culture support (e.g. rope) in the tank to allow attachment of the cuttings; and (iv) placing the support in the sea at a predetermined depth and parallel to the surface. Also claimed are new organosilicon cpds. of formula (I) SiR1R2R3R4 when extracted from the reproductive organs and juvenile tissues of algae, whereby R1-R4 are organic gps., at least one being hydrolysable gp. of the type XR' where X is heteroatom (esp. O) and R' is H or organic gp.
