    Production of aflatoxin B1 by Aspergillus ruber THOM and CHURCH (1989)
    Springer
    Mycopathologia 108 (1989), S. 135-138 
    Details
    ISSN: 1573-0832
    Keywords: aflatoxins ; Aspergillus ruber

    Topics: Biology , Medicine
    Notes: Abstract Production of aflatoxins by Aspergillus ruber THOM and CHURCH was first reported by KULIK and HOLADAY (1967), although these results have lacked confirmation. In this paper we provide evidence that this fungal strain produces aflatoxins. This finding has implications for food hygiene, especially in countries where such moulds are used in the preparation of foodstuffs.

    Preventive measures for microflora and mycotoxin production in foodstuffs (1990)
    Springer
    Archives of environmental contamination and toxicology 19 (1990), S. 437-446

    Notes: Abstract The conservation of foodstuffs by chemical or physical methods is now practiced on a wide scale. Certain procedures (drying, use of pesticides) are well proved and are used on an industrial scale, although in certain situations they are not without risk to human health. New techniques (controlled atmospheres, irradiation, fumigation) are in use and will undoubtedly see further development for conservation of seeds and cereals in both industrialized and non-industrialized countries. In the latter case, the use of cost-effective fumigants may be of particular value. Preventive measures for the control of molds in foodstuffs are discussed in this report.

    Reducing Ammonia Losses by Adding FeCl3 During Composting of Sewage Sludge (1999)
    Springer
    Water, air & soil pollution 112 (1999), S. 229-239

    Notes: Abstract The release of ammonia nitrogen during composting of sewage sludge mixed with a lignocellulosic bulking agent leads to a reduction in the agronomic value of the final compost and to harmful effects on the environment. We propose adding a cheap salt FeCl3 which can be used without special precaution to reduce ammonia losses by decreasing pH conditions. An in-vessel co-composting experiment was conducted in a large reactor (100 L) in which FeCl3 was added to sludge mixed with a bulking agent (pine shavings and sawdust) and compared with a control mixture without FeCl3. Temperature, oxygen consumption and pH were monitored throughout the composting of both mixtures. The final balance of organic matter, organic and inorganic nitrogen permitted to conclude that the addition of FeCl3 reduced nitrogen loss (by a factor of 2.4 in relation to the control) and increased mineralisation of the organic nitrogen by 1.6.
