Focus on microorganisms such as bacteria, fungi, algae, and protists. In a local context, microbes from peat ecosystems or tropical wetlands can be the focus of research as biotechnological agents—for example, in waste treatment, metabolite production, or bioremediation. Examples of studies in microbiology include indigenous peat soil bacteria, bacteria in palm oil sludge waste, and the potential use of fungi and bacteria as biofertilizers.
