Vitamin D is a water-insoluble compound presented in two main forms (D2 and D3), susceptible to environmental conditions. Microencapsulation an alternative supplements preserve vitamin properties foods. Entrapment efficiency (EE) the property evaluate encapsulation effectiveness therefore it of interest study analytical methods for identification quantification this within particle. This paper ...

Yamagishi, Takayoshi (Kanazawa University, Kanazawa, Japan), Shoichi Ishida, and Shoki Nishida. Isolation of toxigenic strains of Clostridium perfringens from soil. J. Bacteriol. 88:646-652. 1964-Strains of Clostridium perfringens were isolated from soil specimens heated at various temperatures for different lengths of time and were toxigenically examined. When higher temperatures were used, fe...

Toxigenic Aspergillus flavus is a primary producer of aflatoxin in Indonesia, and its presence can lead to the contamination agricultural commodities. This poses risk export-targeted commodities, potentially resulting their rejection. Therefore, this study aims characterize molecular profile nativeA. isolated from several Indonesian products, with major focus on toxigenicity toxin production. A...

A modification of the Mueller medium for tetanus toxin production is presented, on which an adapted strain produces high yields of toxin (70 to 90 flocculating units per ml) in the absence of animal protein extracts. The range of iron concentration in the medium was established within which the toxigenic activity of the culture can be made to vary, and the mathematical nature of the variation i...
