SCIENCE “A great obstacle preventing the
unequivocal establishment of the medicinal effect of mushrooms is the
lack of studies which demonstrate the effects on humans.”
and with the dye that was collected at the end of the process great results were obtained when dying silk or cotton fabrics. However, in view of the low cost of industrially produced dyes the question remains as to whether this method can be applied with any financial viability.

ostreatus) and 12% (P. cystidiosus). No negative effect were found which might be related to the consumption of these polysaccharides. These results are particularly interesting in light of the difficulties experienced by diabetics in con- trolling their blood sugar concentrations. Other lectures of note concerned the use of fungi as a source of colorants and as a source of nano- particles. Dr. Subramanian Chandra Sekarenthi- ran spoke on the use of Pycnoporus varieties as a source of orange dye. For this purpose a number of strains of this variety were cultivated on a small-scale in order to investigate which con- ditions resulted in the highest concentrations of natural dye. Subsequently, cultivation on a larger scale was started, using locally available substrates (bagasse, sawdust, rice straw and wood shavings). Extraction methods were tested
A number of subjects were explained in greater detail in brief keynote lectures. Dr. Absar Ahmad gave a high speed lecture on the possibilities of producing nanoparticles from fungi by adding the right salts to the growing medium. The fungi mainly used here were endophytes (fungi that live within the cells of plants). The enzymes responsible for forming the nanoparticles are the sulphite-reductase, nitrate-reductase and hydrolases that are released by the fungi in response to the stress caused by the metal ions in the salts. During the lecture, examples were shown of the potential of allowing these nanoparticles to accumulate in the organs of rats. These particles could be applied in the targeted accumulation of medi- cation in the organs, or as contrast medium in modern medical imaging techniques. A number of non-medical applications were also men- tioned, including making new types of batteries. Prof. Qi Tan gave a very interesting lecture that outlined the various systems that have been used over the years to cultivate Lentinula edo- des. The cultivation of Lentinula has really taken off in the past 30 years, with production of this variety increasing by factor 500. She explained

The ICMBMP8 was attended by 320 visitors, represent- ing about 30 different nationalities.
