The phloem mobility of glucosinolates Open
The transport properties of glucosinolates within Brassica napus are of interest as identification of the mechanism of transport could lead to lower levels being obtained in specific tissues such as the seeds. The phloem mobility of 35S-gl…
The Transport of Sugars in Developing Fruits of Satsuma Mandarin Open
Transport of sugars to the juice sacs of developing satsuma mandarin (Citrus unshui Marc) has been studied in attached fruits and in isolated fruit pieces. 14CO2 fed to the leaves resulted in [14C]sugar accumulation in the juice sacs, main…
A STUDY OF THE EXTRAFLORAL NECTARIES OF <i>RICINUS COMMUNIS</i> Open
SUMMARY A study has been made of the fine structure and exudate composition of the extrafloral nectaries of Ricinus communis. Actively secreting glands were characterized by the presence of well‐developed swollen endoplasmic reticulum, num…
RAPID BEER PRODUCTION AND CONDITIONING USING A PLUG FERMENTOR Open
Beer has been produced very rapidly, with residence time of less than 1 hour, by passing wort continuously through a plug formed from a yeast/kieselguhr mixture. Using malt wort the total output from the fermentor is limited by gradual blo…
A RAPID PROCEDURE FOR REDUCING THE DIACETYL CONTENT OF BEER* Open
Beer produced by rapid fermentation procedures can contain a substantial quantity of precursor substances which give rise to diacetyl and 2,3-pentanedione when the beer is stored. A conditioning unit has been developed which rapidly conver…
FLOCCULATION IN SACCHAROMYCES CEREVISIAE AS INFLUENCED BY WORT COMPOSITION AND BY ACTIDIONE Open
The stage during the fermentation of wort at which cells flocculate is shown to vary with the extent of exponential growth, so that the use of worts with a high content of assimilable nitrogen leads to delayed flocculation. Additionally, t…
