    Miranda, Adamatzky, Jones, Journal of Bionic Engineering 8 (2011) 107–113. Sounds Synthesis with Slime Mould of Physarum Polycephalum Eduardo R. Miranda1, Andrew Adamatzky2 and Jeff Jones2 1 Interdisciplinary Centre for Computer Music Research (ICCMR), University of Plymouth, Plymouth, PL4 8AA UK; [email protected] 2 Unconventional Computing Centre, University of the West of England, Bristol, BS16 1QY UK; [email protected] Abstract Physarum polycephalum is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging behaviour this plasmodium produces electrical activity corresponding to different physiological states. We developed a method to render sounds from such electrical activity and thus represent spatio-temporal behaviour of slime mould in a form apprehended by humans. We show to control behaviour of slime mould to shape it towards reproduction of required range of sounds. 1 Introduction Our research is concerned with the application of novel computational paradigms implemented on biological substrates in the field of computer music. Computer music has evolved in tandem with the field of Computer Science. Computers have been programmed to produce sounds as early as the beginning of the 1950’s. Nowadays, the computer is ubiquitous in many aspects of music, ranging from software for musical composition and production, to systems for distribution of music on the Internet. Therefore, it is likely that future developments in fields such as Bionic Engineering will have an impact in computer music applications. Research into novel computing paradigms in looking for new algorithms and computing architectures inspired by, or physically implemented on, chemical, biological and physical substrates (Calude et al.

  • Culturing Slime Mold
    Culturing Slime Mold Live Material Care Guide SCIENTIFIC BIO Background FAX! Plasmodial slime mold (phylum Myxomycota) lives in dark, moist environments such as under the bark of decaying logs, among mulch, or beneath decaying leaves. Slime mold classification is once again changing. They were in Protista due to their amoeboid-like properties. In the past, slime molds were considered a fungus because they produce fruiting bodies and spores used for reproduction. Slime molds are a group notable for its unwillingness to be neatly classified! Frequently bright in color and large in size (up to 30 cm in diameter), plasmodial slime molds consist of many amoeba-like cells, which form a mass of protoplasm called myxomycota. The organisms are capable of very slow, creeping movement by means of cytoplasmic streaming. During the reproductive stage, called pseudoplasmodium, slime molds tend to migrate to a well-lit area, such as the top of a log, where less moisture is present. They form into a slug-like mass and produce reproductive fruiting bodies, which contain spores. Under adverse conditions (lack of food, water, light, warmth, or pH changes), the organism dries out and forms a hardened mass called a sclerotium. These sclerotia may also grow fruiting bodies, but do not release spores into the environ- ment until conditions once again become favorable for growth. Spores are transported by wind, which results in the spreading of slime molds to new areas. Sclerotium (unfavorable conditions) Pseudoplasmodium (favorable conditions) Aggregate (plasmodial stage) Amoeba/spores Reproductive Fruiting Bodies Figure 1. Life Cycle of Slime Mold Culturing/Media Slime mold is typically cultured from sclerotia rather than from spores.

    Analysis of the volatiles in the headspace above the plasmodium and sporangia of the slime mould (Physarum polycephalum) by SPME- GCMS Huda al Kateb1 and Ben de Lacy Costello1 1Institute for biosensing technology, University of the West of England, Bristol, BS161QY, UK E-mail: [email protected] Abstract Solid phase micro-extraction (SPME) coupled with Gas Chromatography Mass Spectrometry (GC-MS) was used to extract and analyse the volatiles in the headspace above the plasmodial and sporulating stages of the slime mould Physarum Polycephalum. In total 115 compounds were identified from across a broad range of chemical classes. Although more (87) volatile organic compounds (VOCs) were identified when using a higher incubation temperature of 75oC, a large number of compounds (79) were still identified at the lower extraction temperature of 30oC and where the plasmodial stage was living. Far fewer compounds were extracted after sporulation at the two extraction temperatures. There were some marked differences between the VOCs identified in the plasmodial stage and after sporulation. In particular the nitrogen containing compounds acetonitrile, pyrrole, 2, 5-dimethyl-pyrazine and trimethyl pyrazine seemed to be associated with the sporulating stage. There were many compounds associated predominantly with the plasmodial stage including a number of furans and alkanes. Interestingly, a number of known fungal metabolites were identified including 1-octen-3- ol, 3-octanone, 1-octen-3-one, 3-octanol. In addition known metabolites of cyanobacteria and actinobacteria in particular geosmin was identified in the headspace. Volatile metabolites that had previously been identified as having a positive chemotactic response to the plasmodial stage of P.

    Physarum polycephalum (plasmodial slime mold) Species: polycephalum Genus: Physarum Family: Physaraceae Order: Physarales Class: Myxomycetes Phylum: Mycetozoa Kingdom: Amoebozoa Conditions for Customer Ownership We hold permits allowing us to transport these organisms. To access permit conditions, click here. Never purchase living specimens without having a disposition strategy in place. There are currently no USDA permits required for this organism. In order to protect our environment, never release a live laboratory organism into the wild. Primary Hazard Considerations Always wash your hands thoroughly before and after you handle your cultures, or anything it has touched. It is recommended to use gloves when working with mold, fungus, or bacteria. Availability Physarum is available year round. Care Habitat • Plasmodial stage are shipped in a Petri dish on Physarum agar with oats. Your Physarum should be bright yellow in color, and fan shaped. If your Physarum takes on a different appearance it may be contaminated. Contaminated cultures occur when a foreign specimen (something other than Physarum) makes its way onto your culture. This culture should be stored at room temperature in a dark place. The culture should be viable for about 1–2 weeks in its current container. • Sclerotia are hardened masses of irregular form consisting of many minute cell-like components. These are shipped on cut strips of filter paper in a tube. The culture should be stored at room temperature and can be stored in this stage for several months. Care: • Physarum is subcultured onto Physarum agar, and is incubated at room temperature or 25 °C. To maintain viability, plasmodial Physarum should be subcultured weekly.

  • A Would-Be Nervous System Made from a Slime Mold
    A Would-Be Nervous System Andrew Adamatzky** Made from a Slime Mold University of the West of England Keywords Slime mold, nervous system, unconventional computing Abstract The slime mold Physarum polycephalum is a huge single cell that has proved to be a fruitful material for designing novel computing architectures. The slime mold is capable of sensing tactile, chemical, and optical stimuli and converting them to characteristic patterns of its electrical potential oscillations. The electrical responses to stimuli may propagate along protoplasmic tubes for distances exceeding tens of centimeters, as impulses in neural pathways do. A slime mold makes decisions about its propagation direction based on information fusion from thousands of spatially extended protoplasmic loci, similarly to a neuron collecting information from its dendritic tree. The analogy is distant yet inspiring. We speculate on whether alternative—would-be—nervous systems can be developed and practically implemented from the slime mold. We uncover analogies between the slime mold and neurons, and demonstrate that the slime mold can play the roles of primitive mechanoreceptors, photoreceptors, and chemoreceptors; we also show how the Physarum neural pathways develop. The results constituted the first step towards experimental laboratory studies of nervous system implementation in slime molds. 1 Introduction The plasmodium of Physarum polycephalum (order Physarales, class Myxomecetes, subclass Myxo- gastromycetidae) is a single cell, visible with the naked eye, with many diploid nuclei [63]. The plasmodium feeds on bacteria and microscopic food particles by endocytosis. When placed in an environment with distributed sources of nutrients, the plasmodium forms a network of proto- plasmic tubes connecting the food sources (Figure 1a).

  • Physarum Polycephalum
    A HOMOTHALLIC STRAIN OF THE MYXOMYCETE PHYSARUM POLYCEPHALUM A. E. WHEALS Department of Genetics, University of Leicester, England Received May 27, 1970 HE life cycle of the Myxomycete Physarum polycephalum comprises two Takemating phases, a macroscopic multinucleate syncytial plasmodium and small uninucleate amoebae. Meiosis occurs during the formation of spores from the plasmodium and these spores hatch to give the haploid amoebae. The forma- tion of plasmodia from amoebae in strains investigated so far has been shown to be heterothallic (DEE1960) involving the fusion of two haploid amoebae and the subsequent fusion of their nuclei (Ross 1957). It is controlled by a mating-type locus (mt) at which four alleles are known (DEE 1966). A clone of amoebae carries only one mating type and plasmodia are normally formed only when clones of different mating type are mixed. P. polycephalum is potentially useful for the study of differentiation since it allows investigation of gene action in two distinct phases of cellular organization and during the synchronous morphogenetic process of sporulation. Unfortunately, although genetic analysis has been shown to be possible (DEE1962), progress has been slow because of the difficulty of selecting mutants. The uninucleate amoebae can be cultured only on bacteria so that the selective procedures and biochemical analyses which can be used on this stage are limited. The plasmodium can be grown in defined medium (DANIELet al. 1963), has synchronous mitosis and sporulation (HOWARD1932) and has been the subject of many biochemical studies (RUSCH1970). It has not seemed worthwhile to attempt isolating mutants at this stage in the life cycle because the plasmodium is multinucleate, diploid, and arises only by outcrossing.

  • SOP Physarum Polycephalum
    STANDARD OPERATING PROCEDURE: Physarum polycephalum (slime mould) care and use Note: To be undertaken only by trained personnel in conjunction with a current Safety Data Sheet (SDS) and site-specific risk assessment. ___________________ 1. Introduction Physarum polycephalum is a slime mould that grows in dark humid conditions under the bark of decaying trees and amongst leaf litter on the forest floor. It is used as a tool for demonstrating cytoplasmic streaming* locomotion, and plasmodial fusion* to students. Physarum polycephalum is purchased as a living organism and needs to be fed daily and subcultured to prevent it from outgrowing the petri dish. The plasmodium is the active feeding stage of the organism and consists of a mass of multinucleate protoplasm. In moving, the plasmodium may move along many fronts that are connected by veins. Streaming of protoplasm is easily seen within the veins. 2. Context These instructions are for teachers and technicians for the use of Physarum polycephalum for demonstration purposes only. 3. Safety notes Physarum polycephalum is a Risk Group 1* microorganism that is suitable for use in schools. It is not known to be toxic. The petri dish should remain closed during class demonstrations. Physarum polycephalum is a living culture that, if allowed to starve or dry out, may begin to sporulate*. The spores* are unlikely to generate microbial aerosols*. Wear gloves, safety glasses and lab coat/apron when handling. Regard all microorganisms as potential pathogens, and treat them accordingly. 4. Regulations, licences and permits Not applicable 5.
