The purposes of the study was to isolate, to characterize, and to identify rhizobacteria from plant rhizosphere growing in gold and copper mine. The isolation of rhizobacteria used N-free semisolid agar media, TSA, and SLP plus heavy metals (HMs), namely Pb, Cd, and or Cu. Isolated rhizobacteria were subsequently characterized for resistance to higher level of Pb, Cd, Cu in SLP media. Cultural and morphological characterization of rhizobacteria were conducted for cell morphology, motility, Gram staining, and biofilm formation. The rhizobacteria identification used sequence analysis of the 16S RNA gene fragments. The results showed that the majority of rhizobacterial from Cu mine site (66.7% of 21 isolates) were resistant to Cu (72150 ppm) while the majority of rhizobacteria from gold mine site (77.8% of 18 isolates) were sensitive to 72 ppm Cu. Majority of Cu in the soil was insoluble as granules attaching to gravel so that rhizobacteria of Cu mine site have been exposed and adapted to available Cu. This fact, explaining that the rhizobacteria’s MIC value was lower than the total Cu level in the soil. Three HMs-resistant rhizobacter (PbSM 2.1, MGR 334, and CuNFbM 4.1) formed biofilms, which was as one of the resistance mechanism to HMs. This research informed that HM contaminated-soil is better source for obtaining HM resistant rhizobacteria than HM uncontaminated-soil. The use four isolation media produce rhizobacteria which was more diverse than rhizobacteria from each isolation medium. Further characterization needs to be done to obtain HM resistant-rhizobacteria which can be used as biofertilizers and phytoremediation agent.

The objective of this study was to determine the release of S in paddy soil. The experiment was carried out in the greenhouse which the soil sample was taken from three different sites. The treatment consists of (T0) control, (T1) 0.02 g S pot-1, (T2) 0.04 g S pot-1, (T3) 0.08 g S pot-1, (T4) 0.04 g S pot-1 + rice straw. The concentration of S was measured in soil, surface water (soil solution) and leached water. The results showed that the addition of S increased the available S. In general, concentration of S in soil was high for site 1 and 3. It was possible due to the higher clay content for site 1 and 3 compared to site 2. The higher S concentration in soil solution was obtained by treatment T3 for all sites. Sulfur concentration in leached water was higher for T2 compared to T4. It indicated that rice straw could protect the release of S in leached water.
本研究的目的是测定水稻土中硫的释放。试验在温室内进行，土壤样品取自三个不同的地点。处理包括(T0)对照，(T1) 0.02 g S pot-1， (T2) 0.04 g S pot-1， (T3) 0.08 g S pot-1， (T4) 0.04 g S pot-1 +稻草。测定了土壤、地表水(土壤溶液)和浸出水中S的浓度。结果表明，施S使有效硫增加，总体上，站点1和站点3土壤中S浓度较高。这可能是因为1号和3号地点的粘土含量比2号地点高。各试验点土壤溶液中S浓度均以T3处理最高。T2的浸出水中硫浓度高于T4。说明稻草对浸出水中S的释放有一定的保护作用。

Sinbiotic drinks have a very acidic taste, so it is necessary to add sucrose solution to get the best taste. This study aims to determine the effect of adding 65% (v/v) sucrose solution to changes in antibacterial activity of green grass jelly synbiotic drinks during storage in cold temperatures. The finished green grass jelly synbiotic product was given two different treatments, namely the product without the addition of sucrose solution and product with the addition of 10% (v/v) of 65% (b/v) sucrose solution. The product was stored for 28 days at a cold temperature of ± 10oC. Observations were carried out every 7 days for antibacterial activity, pH, total acid, and total lactic acid bacteria. Antibacterial activity was evaluated using the agar diffusion method against pathogenic bacteria including Staphylococcus aureus, Salmonella sp., Bacillus cereus, and Eschericia coli. The results showed that the antibacterial activity, pH, and total lactic acid bacteria of green grass jelly synbiotic drinks both without and with the addition of 65% (b/v) sucrose as much as 10% (v/v) reduced during storage at cold temperatures, while total acid increases. There was no significant difference between the antibacterial activity and the characteristics of the green grass jelly synbiotic drink given 65% sucrose solution and without the addition of 65% sucrose solution. Thus the study concluded that the addition of 65% sucrose solution to increase the preference for the product did not significantly affect the change in antibacterial activity of the green grass jelly synbiotic beverage during storage in cold temperatures.
