    Notes: The effects of phage fri, which was isolated from a commercial meat starter culture, on the growth of Lactobacillus plantarum and on pH development in broth culture were determined. The influence of this phage on pH development in laboratory sausages produced with the aid of four commercial starter cultures was also assessed. In the presence of a phage-sensitive starter culture, phage fri inhibited the growth of the organism and prevented the development of low pH levels when grown in broth culture. In laboratory sausage, the phage-sensitive, lactic-acid starter cultures produced sufficient acid for an acceptable product in the presence of phage fri. Results suggested that product failure in the fermented meat industry due to phage infection would not be common.

    Notes: Summary An immobilized-cell tubular reactor for the continuous fermentation of lactose by Kluyveromyces fragilis was developed. Two types of supporting media were successfully tested; beechwood cubes and activated charcoal pellets. Ethanol productivity of 17.2 g/l/h was achieved from a 15% whey-lactose solution using K. fragilis immobilized on charcoal pellets, with a final ethanol concentration of 18 g/l. The use of two reactors in series demonstrated that it is possible to obtain up to 50 g/l of ethanol in the final product. No decrease in biological activity of the immobilized yeast cells occurred over a period of up to 31 days of continuous operation.

    Notes: Abstract Black peppercorns supported the growth of Aspergillus parasiticus (flavus) NRRL 3145. Incubation at 28 C and RH of 85% for 30 days resulted in profuse conidial production on the reticulate ridges of the peppercorns. An SEM study of these ridges showed that they were cortical eruptions, and the particulate matter present favored mycelial establishment. Hyphal anastamoses were commonly observed. Following this incubation the inoculated peppercorns were stored in the dark at room temperature and ambient humidity for 15 days. Aflatoxin was detected on a minicolumn. Aflatoxin B1 was produced at levels of 60 μg/kg with traces of aflatoxins B 2, G1 and G2. Quantitative estimation was based on a visual comparison with standards by thin-layer chromatography.
