  abstract: Many rivers are affected by high sediment and turbidity due to land erosion and industrial pollution. Chemical coagulants are frequently used to clarify the water. However, it is proven that chemical coagulants are to some extent harmful to the environment. As such, the researchers are still working for safe, biodegradable and efficient flocculants. The potential of microbial flocculant for turbidity reduction from water was conducted by several approaches. In this study, six types of river water fungi (RWF), RWF-1 to RWF-6 were isolated from river water. The fungi showed good potential in terms of turbidity reduction in the shake flask method by entrapping particles from river water and kaolin suspension. The supernatant produced by fungi was applied to reduce turbidity from kaolin suspension and river water. The supernatants produced by the RWF-5 and RWF-6 showed good turbidity removal of 95% and 75% from kaolin suspension and 25% and 23% from river water, respectively. The growth conditions were optimized and showed that 96% turbidity removal was obtained with 0.1% (w/v) malt extract, 3% (v/v) inoculum dose and initial pH 7.0 at 6-day fermentation by the fungus strain RWF-5. The fungal strain RWF-5 was identified as the species of Lentinus squarrosulus RWF-5. The chemical composition of the extracellular myco-flocculant was 5.17 g/L total sugar; 237 mg/L total carbohydrate; 295.4 mg/L protein and 1.15 mg/L glucosamine. The cellulase and laccase activity were 20 U/L & 6.22 U/L, respectively. Fourier transform infrared spectroscopy (FITR) revealed the presence of hydroxyl, carbonyl, amide and amine groups as the main functional groups. The elemental analysis showed that the weight fractions of C, H, O, N and S were 40.9%, 6.0%, 49.8%, 1.7% and 1.4%, respectively. SEM images of the myco-flocculant showed an irregular structure with netted texture and zeta potential value of the myco-flocculant was recorded at -7.0 mV which may be responsible for the myco-flocculatio…
