in the study. Background of the Study According to Harman (2007)‚ Trichoderma spp. are most prevalent culturable fungi that are present in soils and diverse habitats. They are suited to remediate oil-polluted environments. Specific fungus possesses biodegration potential to used oil like crude oil (Obire and Putheti‚ 2009). Morgan (2011)‚ Trichoderma has been shown to establish and proliferate on a range of soilless substrates‚ and colonization is greater on a growing medium.

absorbed by hyphae * 3 types of fungi * decomposer fungi‚ absorb nutrients from nonliving sources * parasitic fungi: absorb nutrients form living sources * mutualistic fungi: both fungus and host organism benefit from relationship (example is mycorrhizal fungus and plant roots) * Mycelium is made up of threads called hyphae. * hyphae may have septate ( cross walls that separate nuclei and cytoplasm into cells) * hyphae may be coenocytic which means

various extracts such as petroleum ether‚ ethylacetate‚ acetone and aqueous against various human pathogenic bacteria such as Escherichia coli‚ Pseudomonas aeurogiosa‚ Lactobacillus‚ Salmonellatyphi and Staphylococcus aureus also with plant pathogenic fungus such as Pestalotia foedians‚ Fusarium oxysporum and Paecilomycesvariotii at different concentrations. Out of the selected various solvent extracts‚ in bacterial study‚ acetone extract showed a maximum zone of inhibition against Staphylococcus aureus

capsulatum yeast phase helps it gets around the human immune system. A following change in the chemicals composition of the fungal cell wall also occurs as the phase shift‚ and thus the antigens change and the immune system retools‚ which enables the fungus to establish in the lungs. Epidemiology: Histoplasmosis is the most common endemic fungal infection in the U.S. with about 250‚000 cases diagnosed per year. Although H. capsulatum can be found throughout the world‚ it is most prevalent

Campbell’s Biology‚ 9e (Reece et al.) Chapter 31 Fungi Though fungal divisions have traditionally been based on modes of sexual reproduction‚ molecular considerations are becoming more important. Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology

treatments is the best‚ we suggested using it as an additive in cosmetics and medicine.In-vitro testing comprised the methods of identifying the anti-fungal property of the treatments. From the collection of plant samples to reading and analyzing of data‚ fungus growth took for four days then the treatment assignment was conducted. The fungi must have similar growth rate to have accurate results.Results showed that pure extract of Lemon grass (Cymbopogon citratus) is the only treatment that controls the growth

Definition * Mycorrhiza is a specialized fungus in the soil which forms close associations with the roots of a vascular plants * In other temperate and boreal successional systems arbuscular mycorrhizal fungi are the primary mycorrhizal associate in early succession‚ whereas in older soils the main associates are ectomycorrhizal fungi (Piotrowski‚ 2008). Arbuscualar Mycorrhizae: Arbuscular mycorrhiza (AM) is the predominant and ancestral type of mycorrhiza in land plants. It’s root
