Antitumor Activity of C-phycocyanin from Arthronema africanum (Cyanophyceae)
Pure C-phycocyanin (C-PC) was isolated from Arthronema africanum to evaluate its potential antitumor effects in vivo and in vitro. Experimental myeloid Graffi tumor in hamsters was used as a model. The cell proliferation assay showed that C-PC treatment, at concentration of 100 μg mL for 24 h, significantly inhibited the growth of Graffi tumor cells (51.4% viability). Agarose gel electrophoresi...
متن کاملPhysiological Characterization of a Synechococcus Sp. (cyanophyceae) Strain Pcc 7942 Iron-dependent Bioreporter for Freshwater Environments
The complex chemical speciation of Fe in aquatic systems and the uncertainties associated with biological assimilation of Fe species make it difficult to assess the bioavailability of Fe to phytoplankton in relation to total dissolved Fe concentrations in natural waters. We developed a cyanobacterial Fe-responsive bioreporter constructed in Synechococcus sp. strain PCC 7942 by fusing the Fe-res...
متن کاملPreparation of desiccation-resistant aquatic-living Nostoc flagelliforme (Cyanophyceae) for potential ecological application
Nostoc flagelliforme is a terrestrial edible cyanobacterium that grows in arid and semi-arid steppes. The continued over-exploitation in the last century has led to a sharp decline of this resource and a severe deterioration of the steppe ecology. Liquid-cultured N. flagelliforme serves as promising algal 'seeds' for resource restoration. In this study, macroscopic (or visible) aquatic-living c...
متن کاملGrowth Responses of Harmful Algal Species Microcystis (Cyanophyceae) under Various Environmental Conditions
Microcystis is a flagrant cyanobacterial genus forming heavy blooms in aquatic environments and often cause serious problems in the management of water quality. In Japan, Micorcystis aeruginosa and Microcytis wesenbergii are commonly found in natural eutrophic water bodies. Although they frequently occur in the same habitat, the mechanisms determining the dominance of the two Microcystis specie...
متن کاملPhotochemical Apparatus Organization in Anacystis nidulans (Cyanophyceae) : Effect of CO(2) Concentration during Cell Growth.
Anacystis nidulans cells grown under high (3%) CO(2) partial pressure have greater phycocyanin to chlorophyll ratio (Phc/Chl) relative to cells grown under low (0.2%) CO(2) tension (Eley (1971) Plant Cell Physiol 12: 311-316). Absorbance difference spectrophotometry of A. nidulans thylakoid membranes in the ultraviolet (DeltaA(320)) and red (DeltaA(700)) regions of the spectrum reveal photosyst...
