A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

1. INTRODUCTION 1.1 ENZYMES THE ENZYMES SPEAK!! “We are the catalysts of the living world! Protein in nature and in action specific; rapid and accurate; huge in size but with small active centres; highly exploited for disease diagnosis in lab centres”. DEFINITION Enzymes may be defined as biocatalysts synthesised by living cells. They are protein in nature (exception RNA acting as ribozyme) colloidal and thermo-labile in character and specific in their action. HISTORICAL BACKGROUND In

Unlike most Aspergillus spp. and Penicillium spp.‚ Fusarium spp. grows in crops before harvest‚ and grows only at high water availability levels and generally considered as field fungi rather than storage fungi (Barney et al.‚ 1995). Mycotoxins are therefore usually produced before or immediately after

Africana for the first time: including Cladosporium sp.‚ Aspergillus flavus‚ Aspergillus sp.‚ Curvularia lunata as well as three unknown species. The fungal extracts were assessed for antibacterial activity against three standard pathogenic bacterial strains: Bacillus subtilis‚ Staphylococcus aureus and Escherichia coli. Most

These molds can cause allergic reactions ranging from congestion to bleeding in the lungs” (Handwerk‚ 2005). This type of mold can be deadly when someone has a weakened immune
