<p>Nucleic acid extracted from environmental samples is an important analyte in instrumental analysis. With respect to the phenomenon in which sodium tungstate promotes the methane production in anaerobic digestion, the analyses of microbial community using RNA were conducted; however, we noticed that only RNA concentration measured by absorbance measurement (NanoDrop) was remarkably high. Therefore, in this study, DNA and RNA were extracted from the anaerobic digestion sludge samples with sodium tungstate, sodium selenite, or sodium molybdate, and these nucleic acids were quantified and compared by absorbance measurement, fluorescence measurement (Qubit), and gel electrophoresis. Interestingly, it was found that only the RNA concentration of the sample containing sodium tungstate measured by NanoDrop was 3 times higher than that by Qubit analysis. In addition, there was no difference between the RNA concentration measured by Qubit and gel electrophoresis. Regarding DNA concentration and the other compounds, there were no differences. Hence, these results indicate that the Qubit system is useful for the quantification of the RNA concentration in the environmental samples.</p>

Most palm oil mills adopted conventional ponding system, including anaerobic, aerobic, facultative and algae ponds, for the treatment of palm oil mill effluent (POME). Only a few mills installed a bio-polishing plant to treat POME further before its final discharge. The present study aims to determine the quality and toxicity levels of POME final discharge from three different mills by using conventional chemical analyses and fish (Danio rerio) embryo toxicity (FET) test. The effluent derived from mill A which installed with a bio-polishing plant had lower values of BOD, COD and TSS at 45 mg/L, 104 mg/L, and 27 mg/L, respectively. Only mill A nearly met the industrial effluent discharge standard for BOD. In FET test, effluent from mill A recorded low lethality and most of the embryos were malformed after hatching (half-maximal effective concentration (EC50) = 20%). The highest toxicity was observed from the effluent of mill B and all embryos were coagulated after 24 h in samples greater than 75% of effluent (38% of half-maximal lethal concentration (LC50) at 96 h). The embryos in the effluent from mill C recorded high mortality after hatching, and the survivors were malformed after 96 h exposure (LC50 = 26%). Elemental analysis of POME final discharge samples showed Cu, Zn, and Fe concentrations were in the range of 0.10–0.32 mg/L, 0.01–0.99 mg/L, and 0.94–4.54 mg/L, respectively and all values were below the effluent permissible discharge limits. However, the present study found these metals inhibited D. rerio embryonic development at 0.12 mg/L of Cu, and 4.9 mg/L of Fe for 96 h-EC50. The present study found that bio-polishing plant installed in mill A effectively removing pollutants especially BOD and the FET test was a useful method to monitor quality and toxicity of the POME final discharge samples.
