“…These experiments show that manganese can affect the fermentation pattern at very low concentrations but do not resolve the conflict over whether manganese is really essential for yeast growth. [3][4][5][6][7][8][9][10] A zinc concentration above 01 ppm is widely regarded as essential in a brewery wort0 and addition of zinc up to 500 ppm has shown little toxic effect1 but in ourcxperiments the presence of 0-6 ppm of zinc in a wort which contained less than 0-01 ppm of manganese (wort 5, Fig. 2) appeared to prevent yeast growth and fermentation.…”

“…Preparation of Worts Low in Metals*-*-"- 8 Procedure /.-Shake 100 ml of 1-040 unhopped wort for 5 min with 2 ml of 1 %ammoniumpyrrolidine-dithiocarbamate (APDQ and 40 ml of 1% 8-hydroxyquinoline (8-HQ) in CHCIj. After the layers separate discard the chloroform layer and repeat the extraction procedure.…”

“…Différents types de réactifs sont utilisables pour l'extraction : les acides carboxyliques, les aminés aliphatiques ou aromatiques, les acides aminés, les phosphates d'alkyl, les composés phénoliques. Certaines études ont porté sur les mécanismes de réaction des interactions entre le métal (BAILAR, 1956 ;STARY, 1964 ;KATZIN, 1966 ;MORRISON et FREISER, 1967 ;MARCUS et KERTES, 1969). La récupération des métaux transférés dans la phase organique et la régénération du solvant s'effectue habituellement à l'aide d'une solution aqueuse d'acide diluée ou encore, par précipitation des métaux directement dans la phase organique.…”
