Microbiology: Orange Decay Lab Report

Orange Decay Lab Report Author Name Institution Affiliation Results and Discussion Initially, a spot of the green mold with 0.5 cm diameter was found, which enlarged to 2 inches in diameter after a day or two. We found that the mycelium was appearing on the surface, and when the fungus began growing, we found that olive green spores were produced. Soon the entire fruit got covered with these olive green spores. On PDA, the fungus gradually formed radial colonies of white airy mycelia. 102570544714 Mycelium growth (%) 100 86 a 80 60 60 b 42.2 c 40 20 0 e 0 e 10 d 0 15 20 25 30 35 40 Graph 1.

This graph shows the effect of relative humidity on the growth of P. digitatum. We accessed the optimum conditions for the growth of P. digitatum and found that the isolated P. digitatum could grow in a wide range of temperatures, starting from 15°C to 30°C. It was also observed that when the temperature reached the level of 25°C, the fungus attained its maximum growth of 85%, and by then, seven days of incubation had passed. When the temperature was 15°C, the growth of the fungus was reduced to an extent, and it did not grow at 35ºC. This made us understand ...
