A.L. Cabrera's treatment of Argentine Vernonias (Cabrera, 1944) included four members of his Section Lepidaploa, subsection Flexuosae, three of which were listed as occurring in Entre Rios Province (Cabrera, 1974). Two of these, V. cognata Less. and V. platensis (Spreng.) Less., were said to be closely related, di!ering from each other only in the number of #owers in the capitulum, diameter of ...

The current study was designed to investigate the potential effect of Spirulina platensis, Arthrospira platensis, (SP) on tissue protection of Nile tilapia (Oreochromis niloticus) through estimation of P53 level. Five isonitrogenous and isocaloric rations containing graded levels of dried SP 5, 7.5,10, 15, and 20 g/kg diet were fed separately to five equal groups of O. niloticus fingerlings, ad...

Immobilization of cyanobacterium Spirulina platensis in sodium alginate (1.5 %) gave the best quality of bead and 15-16 beads were formed per mL of aqueous solution of alginate. The immobilized cells were used in a batch process for treatment of diluted sewage. After 8 days, 95 % of BOD5, 77 % of COD, 90 % of ammonia, and 94 % of TSS were removed.

This study presents the effect of sewage waste water on growth microalga Arthrospira platensis using appropriate standard methods. The results showed that different concentrations affected platensis. A comparison responses treatments revealed there was significant difference (p<0.05) with control (0%) and 5% having highest mean values for when compared other treatments. Among treatments, 30%...
