Brown-rot fungi decompose only carbohydrate components of wood‚ leaving most of the lignin unaltered. White-rot fungi that decompose all major components of wood equally and eventually decay the wood completely. 7. No people live in the boreal forest of Russia 8. Perhaps the biggest

Introduction: Mycelium is a fungal colony comprising of branched tubular filaments‚ called hyphae‚ that is enclosed by a rigid cell wall (1). Furthermore‚ mycelium makes up the body structure of fungi and is the primary element for fungal development (2). By using this mycelium from fungi‚ materials can be created with many of the same properties of conventional synthetics‚ whilst having less destructive effects on the environment (3). These compostable materials are able to break down‚ unlike styrofoam

Edgar Allan Poe is considered by many to be one of America’s greatest literary figures. Many of his poems and short stories have a mysterious or gothic theme. Two short stories in particular‚ “Ligeia” and “The Fall of the House of Usher” have many of the standard gothic elements like remote settings and supernatural occurrences. While there are some gothic elements in both “Ligeia” and “The Fall of the House of Usher‚” the use of gothic elements is more pronounced in the later. When comparing the

decomposers. Classification of Microorganism Microorganisms are very diverse. They include bacteria‚ fungi‚ archaea‚ and protists. Microorganisms can be found almost anywhere in the taxonomic organization of life on the planet. Bacteria and archaea are almost always microscopic‚ while a number of eukaryotes are also microscopic‚ including most protists‚ some fungi‚ as well as some animals and plants. Viruses are generally regarded as not living and therefore are not microbes‚ although

Occurrence of Arbuscular Mycorrhizal Spores in Soils of Some Legumes and Their Response to Varying Concentration of Phosphorus Application Abstract An experiment was undertaken to investigate the occurrence of Arbuscular Mycorrhizal (AM) fungi in the soil of five leguminous plants: Cajanus cajan‚ Centrosema pascurum‚ Crotolatia ochroleuca‚ Lablab purpurens and Mucuna pruriens. The effects of soil treatments with varying phosphorus concentrations‚ on the population of AM spores under these legumes

MIC Practical Report Kerry Haarhoff 18 April 2012 3150540 Introduction Bacteria and fungi are both micro-organisms‚ however‚ fungi are spore-producing organisms whereas bacteria are not and fungi can be multicellular and bacteria is only a unicellular organism. These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas.
