This paper reports on the recent outcomes from our research into Unconventional Computing for sound and music using slime mould of Physarum polycephalum. This slime mould is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging behaviour it produces electrical activity corresponding to different physiological states. We developed a method to render ...

THE fat content of mould mycelium, as reported by various authors, ranges from 1 to 40 %, depending upon the species and upon the conditions of growth. Even within a single strain of a species certain characteristics of the fat, as well as its amount, have been reported to vaty with the conditions of growth. From what is known about the chemical composition of mould-fat it appears that glycerid...

Slime mould P. polycephalum is a single cells visible by unaided eye. The cells shows a wide spectrum of intelligent behaviour. By interpreting the behaviour in terms of computation one can make a slime mould based computing device. The Physarum computers are capable to solve a range of tasks of computational geometry, optimisation and logic. Physarum computers designed so far lack of localised...

The influence of temperature on the growth of the mould Penicillium roqueforti growing on malt extract agar was studied by correlating the produced heat (measured by isothermal calorimetry), ergosterol content (quantified by GC-MS/MS) and biomass of the mould at 10, 15, 20, 25 and 30 degrees C. The results were analysed with a simple metabolic model from which the metabolic efficiency was calcu...

Slime mould Physarum polycephalum is a single cell visible by the unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately ≈40 °C, the electrical resistance of the protoplasmic tube increases from ≈3 MΩ to ≈10,000 MΩ. The organism's resistance is not proportional nor correlated to the temperature of its environment. Slime mould...

A diploid and a haploid strain of Pichia anomala were tested for their biocontrol ability against the spoilage mould Penicillium roqueforti in glass tubes filled with grain at two water activities (aw). At aw 0.98, the two yeast strains grew and inhibited mould growth equally well and showed similar patterns of ethyl acetate production, reaching maximum values of 10-14 microg ml(-1) headspace. ...
