Studies were carried out to isolate and identify microorganisms for probiotic use for chickens. Selection of strains included various criteria such as agreement with bio-safety aspects, viability during storage, tolerance to low pH/ gastric juice, bile, and antimicrobial activity. The strains were isolated from the crop, proventriculus, gizzard, ileum and caeca of chicken. Decimal dilution of the contents of these segments were mixed with MRS medium and incubated for 48 h at 37°C under anaerobiosis. The identity of the culture was based on characteristics of lactobacilli as presented in the Bergeys Manual of Determinative Bacteriology, carrying out bacterioscopy (morphology), Gram stain, growth at 15 and 45°C, and fermentation of different carbon sources.... |

Solid state fermentations were carried out to test the efficacy of Ceratocystis fimbriata to grow on different agro-industrial substrates and aroma production. Seven media were prepared using cassava bagasse, apple pomace, amaranth and soya bean. All the media supported fungal growth. While amaranth medium produced pineapple aroma, media containing cassava bagasse, apple pomace and soya bean produced a strong fruity aroma. The aroma production was growth dependent and the maximum aroma intensity was detected a few hours before or after the maximum respirometric activity. Sixteen compounds were separated by gas cromatography of the components present in the headspace and fifteen of them were identified as acid (1), alcohols (6), aldehyde (1), ketones (2)... |
