Using Palm Oil Mill Effluent (POME) as a medium for culturing oleaginous yeast is advantageous simultaneous lipid production and waste removal. The organic compounds in POME can be utilised nutrient source growth. Rhodotorula toruloides was cultivated filtered unfiltered raw growth media this study. growth, pH changes media, removal of chemical oxygen demand (COD) were examined compared to grow...

High organic materials in palm oil mill effluent (POME) can result serious water pollution. To date, biological treatment has been used to reduce the environmental risks of these effluents prior their discharge into streams. However, effluents’ dark brownish colour remains as a significant issue that must be addressed, it affects overall quality water. Although membrane technology frequently ad...

In this study, the performance of dielectric barrier discharge (DBD) with aerated condition at voltages 15, 20, and 25 kV on production biogas; CH4, H2, CO, CO2 removal COD BOD from POME were investigated. The experimental results showed that a rate 2.5 L/min high voltage (25 kV) produced was 9.4, 21.5, 19.6 times higher than non-aerated one, respectively. maximum cumulative volume 95.4 ± 8.92,...

Two methods based on the principle of maximum entropy (POME), the ordinary entropy method (ENT) and the parameter space expansion method (PSEM), are developed for estimating the parameters of a four-parameter exponential gamma distribution. Using six data sets for annual precipitation at the Weihe River basin in China, the PSEM was applied for estimating parameters for the four-parameter expone...

Streptomycin is used in plant agriculture for bacterial disease control, particularly against fire blight in pome fruit orchards. Concerns that this may increase environmental antibiotic resistance have led to bans or restrictions on use. Experience with antibiotic use in animal feeds raises the possible influence of formulation-delivered resistance genes. We demonstrate that agricultural strep...

Fire blight, a devastating bacterial disease in pome fruits, causes severe economic losses worldwide. Hitherto, an effective control could only be achieved by using antibiotics, but this implies potential risks for human health, livestock and environment. A new approach allows transient inhibition of a step in the flavonoid pathway, thereby inducing the formation of a novel antimicrobial 3-deox...

Membrane reusability determines the economic sustainability of separation process. However, membrane was deduced by antifouling properties, while actual reuse performance using palm oil mill effluent (POME) is rarely reported. This study investigates nano-Fe3O4/PVDF (PVDF1) for POME treatment. The chemical oxygen demand (COD), total suspended solid (TSS) permeate, molecular weight cut off (MWCO...

A pre-culture stage is required to obtain robustly-dividing cells with high hydrogen (H2) production capabilities. However, a step-by-step process for biohydrogen scarcely reported, mainly from palm oil wastewater. Therefore, this study developed guideline find the best inoculum heat treatment conditions and implement selected using This used raw mill effluent (POME) POME sludge as substrate in...

Palm oil mill effluent (POME) is wastewater containing dissolved materials with concentrations above the threshold. Generally, POME processing in Indonesia uses an open pond system. It less efficient because it requires large areas and causing greenhouse gas effects. This research aims to improve processing, three methods were studied; bioremediation using enrich indigent lypholitics bacteria (...
