 en Modulation of unsaturated fatty acids content in algae Spirulina platensis check for this species in other resources and Chlorella minutissima check for this species in other resources in response to herbicide SAN 9785

Abstract

The accumulation of polyunsaturated fatty acids by algae Spirulina platensis check for this species in other resources and Chlorella minutissima check for this species in other resources was studied. Response of these organisms to the substituted pyridazinone, SAN 9785, an inhibitor of the long chain fatty acid desaturase, indicated that fatty acid synthesis and their desaturation were regulated differently in these organisms. While the pool of palmitic acid, the precursor for the unsaturated C18 fatty acids, was stringently maintained in the green alga C. minutissima, in the cyanobacterium S. platensis the level of palmitic acid was liberally maintained in spite of the enhanced accumulation of unsaturated C18 fatty acids.

Keywords
Chlorella minutissima, fatty acid desaturation, polyunsaturated fatty acids, Spirulina platensis, SAN 9785.
