Evaluation of the Thermal Stability Profile of Aflatoxins from Fungal
Isolates from Dried Fishes
- Abstract: Publication date: Aug 2023
  Source:International Journal of Biochemistry and Biophysics Volume 11 Number 2 Azudiugwu Obianuju Sabina George-Okafor Uzoamaka and Onuorah Samuel Chinedu Ready-to-eat fishes have been associated with aflatoxin-producing fungi which are of public health concern, hence this study on the evaluation of thermal stability of aflatoxins recovered from fungi isolated from dried fishes. Five dried fish samples were cultured on Sabouraud dextose agar and identified phenotypically. The fungal isolates were Aspergillus niger, Aspergillus fumigatus and Fusarium ventricosum. The isolates were assayed for aflatoxins both qualitatively and quantitatively using high performance thin layer chromatography under the ultraviolet light at a wavelength of 365nm. Aspergillus niger and Aspergillus fumigates significantly (P

Effective Bioassay for Vinegar Production Using African Star Apple
(Chrysophyllum albidum G. Don) by Enzymatic Catalysis and Acetic
Bioconversion
- Abstract: Publication date: Aug 2023

Kplaïssa Edwige Dahouenon Ahoussi Daniel Chougourou Akadiri Yessoufou Lamine Baba-Moussa and Dominique C. K. Sohounhloue The present study aims to valorize the neglected and underutilized fruits of Chrysophyllum albidum in vinegar production through enzyme catalysis and acetic bioconversion. To do this, Chrysophyllum albidum juice was extracted from ripe fruits by using a pectinolytic enzyme (Pectinex Ultra SP-L) at a concentration of 1ml.kg-1. The extracted juice was first subjected to alcoholic fermentation using yeast strains of Saccharomyces cerevisiae in anaerobic conditions, and secondly to an acetic fermentation using strains of Acetobacter spp. isolated from unpasteurized cider vinegar. Results obtained indicated that the use of the pectinolytic enzyme significantly improves (p
