Production of Mycofungicidal Pellets from chaetomium globosum

Abstract

Mycofungicidal pellets wee produced from Chaetomium globosum by using spore suspension (4 x 10 spores/ml.) mixed to 1% sodium alginate and 10% hydrous aluminum silicate for one litre, then agitated through an electrical blender. The pH of such mixture was 6.8. The mixture was dripped into either a solution of 0.1 M calcium gluconate or 0.25 M calcium chloride for immediately formed pellets. The alginate pellets were then air dried for 12 hours. The average diameter of dried pellets were approximately 3 mm. survival tests at 24 hr and 4, 8, and 12 weeks revealed that the pellets with calcium chloride and calcium gluconate are not significantly different of survival during storage at room temperature. However, the percentage of survival declined with time during storage.
