Influence of culture media on growth, colony character and sporulation of Chaetomium globosum fungus

The mycelial growth rate, colony character and sporulation pattern of Chaetomium globosum, grown on seven different culture media viz., Potato Dextrose Agar (PDA), Czapek’s Dox media, Yeast Extract Agar, Sabouraud media, Oatmeal Agar, Malt Extract Agar and Lignocellulose Agar (LCA) were observed after seven days of incubation at 25±1°C. The colony diameter, culture characteristics and sporulation of Chaetomium globosum were greatly influenced by the type of growth medium used. Sabouraud medium exhibited comparatively higher mycelial growth of Chaetomium globosum, followed by Potato Dextrose and lignocelluloses agar medium. With regard to sporulation, excellent sporulation was observed on sabouraud medium. Poor sporulation was observed on malt extract agar. These results will be useful for fungal taxonomic studies. | Influence of culture media on growth colony character and sporulation of Chaetomium globosum fungus
