Streptomycetes and aerobic bacteria able to utilize cysteic acid and taurine as sole sources of energy, nitrogen and sulphur were isolated from soil materials. None of the isolated fungi did this. The bacterium which was used in most experiments grew on both compounds. The sulphur of the compounds was recovered as sulphate and most of the nitrogen as ammonia after breakdown by growing or pregro...

Disulphide bonds and sulphhydryl concentrations were evaluated to determine the effects on rheological, thermodynamic, pasting, dynamic rheological characteristics of mixed flours. Gluten samples, first treated with sodium sulphite different concentrations, added into flour at a 4% level, which had significant impact free sulphhydryl, disulphide bonds, ratio two indices. There was no relevance ...

Sulphites are widely used as preservative and antioxidant additives in the food and pharmaceutical industries. Exposure to sulphites has been reported to induce a range of adverse clinical effects in sensitive individuals, ranging from dermatitis, urticaria, flushing, hypotension, abdominal pain and diarrhoea to life-threatening anaphylactic and asthmatic reactions. Exposure to the sulphites ar...

IN Part V [Gulland and Randall, 1935] it was shown that the molecule of the oxytocic hormone certainly contains one, and may possibly contain two, oxidation-reduction systems, although the existence of the second is not definitely established. The present communication describes the actions on the hormone of some oxidising and reducing agents, which were studied in the hope that they might thro...

ISSN 0001-5555 Sulphites, such as sodium bisulphite and sodium metabisulphite, are widely used as antioxidants or preservatives in a wide range of substances, such as food, cosmetics and medications (1). It has been reported that sulphite intake can cause systemic type I allergic reactions, such as u...

The transition element molybdenum (Mo) is essential for (nearly) all organisms and occurs in more than 40 enzymes catalysing diverse redox reactions, however, only four of them have been found in plants. (1) Nitrate reductase catalyses the key step in inorganic nitrogen assimilation, (2) aldehyde oxidase(s) have been shown to catalyse the last step in the biosynthesis of the phytohormone abscis...
