Fusarium oxysporum is one of the soil-borne pathogens that is able to cause damage to plants with an attack intensity of up to 35%. Farmers still use synthetic fungicides to eradicate them. The use of synthetic fungicides has a negative impact on the environment. One of the alternative efforts that can inhibit the growth of Fusarium oxysporum is by utilizing bacteria as antagonistic agents. One…
Energy needs continue to increase in Indonesia by 1,185.56 BOE (Barrel of Oil Equivalent) which is dominated by petroleum energy. This causes widespread petroleum management activities which produce waste in the form of hydrocarbon compounds because they are toxic to the environment. Management of hydrocarbon compounds needs to be done, one of which is through bioremediation using bacteria. Thi…
Staphylococcus aureus is an opportunistic pathogenic bacterium capable of forming biofilms, protective structures that make it more resistant to antibiotics. These biofilms play an important role in chronic and intractable infections. One alternative approach to overcome this problem is to utilize natural bioactive compounds, such as secondary metabolites from the fungus T. harzianum. T. harzia…
