Mixed cultures of strains of opposite sex ("mated" cultures) of Blakeslea trispora contain trisporic acids and other apocarotenoids, some of which mediate the sexual responses of this fungus and other Mucorales. In mated cultures of the wild-type strains F986 and F921 we identified eleven apocarotenoids: two C(18) trisporoids, three C(15) compounds with a monocyclofarnesane skeleton, a C(13) co...

Nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. Importance of the magnetic nanomaterials in biomedical science cannot be overlooked. The most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. However monodispersion, selection of an appropriate coati...
