Write an essay on the role of fungi in wood and litter decay. [40] Fungi‚ together with bacteria‚ are the principal decomposers in the biosphere. They break down organic materials and return the substances locked in those molecules to circulation in the ecosystem. Fungi can break down cellulose and lignin‚ an insoluble organic compound that is one of the major constituents of wood. By breaking down such substances‚ fungi release carbon‚ nitrogen‚ and phosphorus from the bodies of living

Identification and Impact of Airborne Fungi over the Sydney Basin Introduction The need to identify and monitor airborne fungi is vital to the health of humans. Fungal spores may trigger allergic responses in sensitised people‚ causing respiratory diseases such as hayfever and asthma (Knox‚ Ladiges‚ Evans and Saints 2006). A variety of techniques can be used to identify the diversity and density of fungi within the Sydney Basin. The use of agar plate exposure allows microbial colonies to

Fungi is one of the five kingdoms of the living world that contains a diversity of organisms‚ there is an estimation of about 1.5 million species of fungi worldwide out of which‚ approximately 120000 species and majority tends to be living in an environment which is either aquatic or terrestrial ascomycetes and basidiomycetes species (Kirk‚ 2008). Have been described till date‚ however the numbers are dynamic in steadily escalating (Hawksworth‚ 1991) Cercospora zeae-maydisis fungus that is responsible

between bacteria viruses‚ Fungi and Parasites. Viruses are pieces of nucleic acid (DNA or RNA) wrapped in a thin coat of protein that replicate only within the cells of living hosts. Bacteria are one-cell microorganisms with a simple cellular organization whose nucleus lacks a membrane. Parasites may be protozoa‚ yeasts‚ or multicellular organisms such as fungi or worms that live in or on a host to obtain nourishment without providing any benefit to the host. Fungi There are many different

TAQ1 Definition of Pathogen and research into the main features of bacteria‚ protozoa‚ fungi and viruses. Pathogens‚ or infectious agents‚ are microorganisms that cause disease or illness to their host. There are divided into four groups; bacteria‚ protozoa‚ fungi and viruses. The term pathogen most often describes an organism that disrupts the normal physiology of a plant or animal. In identifying a pathogen it is important to determine the properties that ‘contribute to its infectious

ASSAY OF OIL-DEGRADING POTENTIAL OF FUNGI ISOLATES ON DIESEL‚ KEROSENE AND PETROL USING ENRICHMENT METHOD. BOBOYE B.‚ *OLUKUNLE O. F.‚ ADETUYI F. C. AND ADEBIYI G. A ABSTRACT A study was carried out to assay for oil-degrading potential of fungi isolates on diesel‚ kerosene and petrol. Water samples were collected aseptically and analyzed microbiologically using standard techniques. The fungi isolated from the water samples were: Trichoderma viridae‚ Aspergillus niger‚ Aspergillus fumigatus

P1: you must explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. P2: you must explain how pathogenic microorganisms grow and spread. In this assignment I am going to explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. I will then explain how pathogenic microorganisms grow and spread. Infection is the process where germs enter a susceptible area in the body‚ where they multiply‚ resulting in disease. Colonisation is where microbes are present

Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under
