[en] This study was aimed to evaluate the human efficacy of the herbal preparation(HemoHIM) on the immune and hematopoiesis enhancement in sub-healthy volunteers. It was conducted as a double-blind, placebo-controlled human study. The sub-healthy volunteers with peripheral White Blood Cell (WBC) counts below 5000/μl were recruited and randomly allocated to 3 groups and administered with HemoHIM 6g/day, HemoHIM 12g/day, or placebo throughout the test. Peripheral blood was collected 4 times before or after the administration and analyzed for the hematological and serum biochemical values, immune cell activities, antioxidant status of plasma. The data of 38 volunteers were finally included in the analysis. Although there were no statistical significances, a trend was observed that the dose and duration of HemoHIM administration was correlated to the increased number of immune cells (white blood cells and lymphocytes). NK cell activity was increased significantly in the male group administered with HemoHIM 6g/day. The cytokines involved in immune activation (IL-2, IFN-γ, IL-6) were significantly increased or showed the trends of increases in HemoHIM administered groups, while IL-4 involved in allergy and asthma was not changed or showed the trends of decreases in HemoHIM administered groups. On the other hand, the antioxidant biomarkers such as total GSH, MDA, and TAS, were not affected by HemoHIM administration. The toxicological safety of HemoHIM administration was confirmed by the serum biochemical analysis of liver and kidney function markers and the questionnaire of HemoHIM administration and the consultation with the doctor, which showed no side effects of HemoHIM administration. The results of this study may provide the basic data for further clinical study on HemoHIM
[en] The growth of the algae Chlorella vulgaris, Botryococcus braunii and Scenedesmus sp. under mixotrophic conditions in the presence of different concentrations of crude glycerol was evaluated with the objective of increasing the biomass growth and algal oil content. A high biomass concentration was characteristic of these strains when grown on crude glycerol compared to autotrophic growth, and 5 g/L glycerol yielded the highest biomass concentration for these strains. Mixotrophic conditions improved both the growth of the microalgae and the accumulation of triacylglycerols (TAGs). The maximum amount of TAGs in the algae biomass was obtained in the 5 g/L glycerol growth medium. The fatty acid profiles of the oil for the cultures met the necessary requirements and the strains are promising resources for biofuel production. Keywords: biomass; glycerol; microalgae; mixotrophic; oil content
[en] Several forms of the phosphorus in wastewater were analyzed using a fraction method with a membrane reactor. A primary aim of this study was to differentiate the two main groups, as either 'biologically bound' or 'physicochemically bound,' with the quantification of bound phosphorus in animated sludge. After the four-level extraction treatment with distilled water and various solvents such as bicarbonate-dithionate, NaOH and HCl, the redox-sensitive-P and P bound to Fe(III)-hydroxides were found as main precipitation products in the anaerobic chamber (AN). Whereas the aerobic chamber (AE) contained mainly the precipitates of P bound to metals, such as Al and Fe, sorptive-bound phosphorus on metals and organic compounds etc. With iron precipitation, the levels of Fe-P, Al-P, and Fe-P adsorbed by Fe(OH)3 were particularly high in the AE and AN. The sum of inorganic-P (physicochemically bound phosphorus) increased with iron precipitation, whereas that of organic-P and poly P (biologically bound phosphorus) decreased.
[en] The effect of acetate was examined during the p-removal and denitrification of wastewater. The plant was operated based on the sequencing-batch-biofilm-reactor (SBBR) process. As microbial media, ca. 9 mm Bio-Flow granules made from polyethylene and polypropylene were used. Three preparations were made to compare the level of biological p-removal and denitrification. In comparison to the batch test, 42 mg/L (AC 30) and 84 mg/L (AC 60) of NaCH3COO were mixed with the 500 mL of raw wastewater and the effect of the acetate concentration on the level of p-removal was monitored. All samples were immediately filtered with 0.45 μm membrane filter, and PO4-P, NO3-N, NO2-N and acetate were analyzed using Ion Chromatography, whereas Ptotal and chemical oxygen demand (COD) were measured by a spectrophotometer. The p-removals for the WW, WW + AC 30 and WW + AC 60 preparations were found to be 9.4, 9.1 and 13.1 mg/L, respectively. The WW + AC 30 preparation did not show any significant effect on the p-removal, while p-removal in WW + AC 60 preparation was higher than that in the other two preparations. A comparison of the data revealed the COD: NO3-N:AC:P ratio of the WW, WW + AC 30 and WW + AC 60 preparations to be 18.07:2.90:6.87:1, 21.28:2.45:5.98:1 and 15.95:2.75:6.18:1, respectively. The experimental results showed that approximately 7 mg/L of acetate was consumed per 1 mg/L of p-removal
