Expanded polystyrene (EPS) is a polymer known for its remarkable resistance to degradation. Despite several studies conducted on degradation, there still limited information about the use of White Rot fungi (WRF) degrade EPS. Our study aims explore potential WRF, which are have isozymes laccase, powerful oxidoreductases that potentially could aid in EPS biodegradation. We evaluated results based two parameters: (1) morphological damage observed through gravimetry and Scanning Electron...

Endophytic fungi have been known as potential source of bioactive compound, similar to their host. This study was conducted identify endophytic Diaporthe spp. isolated from Cinchona calisaya and explore in producing alkaloids, particularly quinine. A total 39 strains were identified using ITS1-5.8S-ITS2 EF1-α gene. Seventeen species name they represent eight i.e. D. cynaroidis, endophytica, ganjae, gardeniae, litchicola, phaseolorum, pseudomangiferae, rhoina. The re­maining 22 represents...

Abstract Sorghum is a local product that quite prospective in providing carbohydrate sources. Processing sorghum seeds into flour one alternative to replace the consumption of wheat which continues increase. However, used composite will provide dry, sandy and crumb properties are hard so fast, other processes need be done improve its characteristics. Soaking germination can reduce antinutrient compounds also increase nutritional value. The purpose this study was obtain time temperature...
