The discovery of new antimicrobial compounds is critical due to increasing resistance of microorganisms to existing antimicrobials. Thermophilic fungi and bacteria from extreme environments, such as hot springs, show potential as sources of bioactive compounds due to their unique metabolic adaptations to high temperatures. In this study, bioactive compounds from Aspergillus fumigatus LBKURCC269…
Background and objectives: Laccase is a multi-copper oxidase, a green catalyst in dye bioremediation. One of the laccase producers is Trichoderma asperellum LBKURCC1 and is utilized in the bioremediation of textile dye Methyl Blue (MB). MB is a triphenylmethane dye, and is widely used in the textile industry, is toxic and difficult to degrade. Methods: The potential of T. asperellum LBKURCC1 in…

Dahlia tubers contain fungus Sporothrix sp. which have antimicrobial activity. The objective of this research was to determine the agitation (75,100,125,150 and 175 rpm) that effect the activity of antimicrobial in malt extract broth (MEB). The result showed that agitation of 150 rpm have the antimicrobial activity. It produced the inhibition zone of 21,00±0,58 mm againts Staphylococcus aureus…
Oil palm frond waste can be utilized as compost through fermentation process. This research aimed to study the ability of local bioactivatorsTrichoderma asperellum (LBKURCC1 and LBKURCC2) to degrade palm fronds with a series of pile reversing variation during composting. Composting process was started with chopping palm fronds in a size of ±5 cm, and those chopped palm fronds were arranged int…
