Broodstock feeding effects on spawning performances’ (fertility, eggs and larvae quality) of the Mediterranean red porgy (Pagrus pagrus, Linnaeus 1758) during two years
Spawning in captivity of two broodstock groups of red porgy (Pagrus pagrus) of the same age was studied during two consecutive spawning seasons. These two broodstock groups, designed as A and B, were fed with different regimes during the spawning period. Group A was fed on moist pellet while group B was fed on fresh fish. Total number of collected eggs was 22 and 36 million respectively for groups A and...

Effect of refining on the quality and composition of groundnut oil
Crude groundnut oil was obtained by solvent extraction from groundnut seeds and refined. The crude and refined oils were then analyzed. The results obtained show that the acid value decreased from 2.890 to 0.420 mg/KOH. Free fatty acid decrease after refining from 2.82 to 2.02%; phospholipids decreased from 23.11 to 5.53%; copper content decreased from 0.37 to 0.0361% and iron decreased from 3.98 to...

Simultaneous effect of divalent cation in hydrolyzed cassava starch medium used by immobilized yeast for ethanol production
Response surface methodology was adopted in a central composite design to optimize ethanol production from cassava starch hydrolysate medium. Starch hydrolyzate was prepared from TMS 98/0581, a genetically developed cassava mosaic disease-resistant variety. The yeast whole cell, Saccharomyces pastorianus, a lager brewing strain (726 x 106 cells/ml, 98.78% viability) and fungamyl and termamyl...
