We have isolated a member of the HNF-3/forkhead gene family in ascidians as a means to determine the role of winged-helix genes in chordate development. The MocuFH1 gene, isolated from a Molgula oculata cDNA library, exhibits a forkhead DNA-binding domain most similar to zebrafish axial and rodent HNF-3beta. MocuFH1 is a single copy gene but there is at least one other related forkhead gene in ...

The present study has revealed that, the temperature has a crucial role among the observed physiochemical parameters on the growth and survival of P. margaritifera spat. Instantaneous growth rates (IGRs) in DVM, APM and TWT were calculated and used to assess the variation in growth of spat reared with different feed mixtures (FM-1 8) of five diatoms and stocking densities (SD-10, 20 and 30). Am...

Background: Microalgal lipid is a promising feedstock for biodiesel production. The aim of the present study was to investigate the effects of cultivation temperature on the growth and lipid accumulation properties of Nannochloropsis oculata microalgae. Methods: Nannochloropsis oculatacan grow in a wide range of temperatures (5 ~ 35°C). Late in the stationary growth phase of microalgae, bi...

Nannochloropsis oculata is a microalgae that acts as natural food source in fisheries. The need for N. can be met through progressive culture starting from laboratory scale to provide inoculant stock mass using concrete tubs. of begins with the preparation and sterilization media equipment, fertilizer production, scale, intermediate observing density water quality. lag phase occurs on first sec...

Marine algae are considered a source of different bioactive constituents including protein, oil, fiber, vitamins, pigments and dietary minerals. To evaluate the fine chemical biochemical properties marine microalga Nannochloropsis oculata macroalga Ulva lactuca, present study was carried out. The cultivated N. oculate collected U. lactuca were washed, oven-dried, ground subjected to analysis mo...
