Evaluation of crude preparations of Saccharomyces cerevisiae (ATCC 52712) pectolytic enzymes in cassava starch extraction: Effects of variety on yield and starch recovery rates
Application of enzyme preparations has shown great potential in aiding extraction procedures. However, the focus has mostly been on single crop varieties, thereby limiting knowledge on the effects of enzyme technology to those (single) varieties studied. The present work compared the effects of various dosages of crude pectolytic enzymes from Saccharomyces cerevisiae (ATCC 52712) on yield and extraction rates of starch...

Fermentation of deproteinized cheese whey by Saccharomyces fragilis IZ 275 for ethanol production on pilot scale
Cheese whey is presented as an alternative for the production of ethanol to be a major source for growth of microorganisms, which catalyze lactose directly to ethanol and other products. Thus the aims of this study were to analyze the influence of nutrients in the cheese whey (15%w/v) fermentation by Saccharomyces fragilis IZ 275, to estimate the ethanol production and verify the repetition of the results of...

Adoption of pelleted Digitalia iburua grain as carrier for heat stable Newcastle disease vaccine virus for village poultry
The development of pelleted food–based vaccine against Newcastle disease (ND) using a thermostable NDVI2 strain in Acha (Digitalia iburua) is reported. The Acha cereal was subjected to rigorous processing of washing, soaking, boiling, roasting and grinding into fine powder prior to virus incorporation. The mixture which was passed through a locally fabricated pelleting machine resulted in fine pellets. The virus...

Aroma characterization of ripe date fruits (Phoenix dactylifera L.) from Algeria
The headspace of eight Algerian date varieties with low market value were analyzed for their aroma compounds using solid phase micro extraction and gas chromatography combined with mass spectrometry. In this study, 61 identified compounds were categorized in various chemical classes on the basis of their functional groups, alcohols, esters, aldehydes, terpenoids, ketones, hydrocarbons, and ethers. Twenty specific...
