DATA FROM: PRODUCTION OF BIOADSORBENT FROM PHOSPHORIC ACID PRETREATED PALM KERNEL SHELL AND COCONUT SHELL BY TWO-STAGE CONTINUOUS PHYSICAL ACTIVATION VIA N2 AND AIR
DESCRIPTION : In the present study, agricultural biomass; palm kernel shell (PKS) and coconut shell (CS) were used to produce high porosity bioadsorbent using two-stage continuous physical activation method with different gas carrier (air and N2) in each stage. The activation temperature was set constant at 600°C, 700°C, 800°C or 900°C for both activation stages with the heating rate of 3°C min-1. Two parameters including the gas carrier and activation temperature were determined as the significant factors on the adsorption properties of bioadsorbent. BET, SEM, FTIR, TGA, CHNS/O and ash content were used to elucidate the developed bioadsorbent prepared from PKS and CS and its capacity towards the adsorption of methylene blue and iodine. The novel process of two-stage continuous physical activation method was capable to emerge mesopores and micropores that were previously covered/clogged in nature, and simultaneously creating new pores. The synthesized bioadsorbents showed that the surface area (PKS: 456.47 m2 g-1; CS: 479.17 m2 g-1), pore size (PKS: 0.63 nm: CS: 0.62 nm) and pore volume (PKS: 0.13 cm3 g-1, CS: 0.15 cm3 g-1) were significantly higher than that of non-treated bioadsorbent. The surface morphology of the raw materials and synthesized bioadsorbent were accessed by SEM. Furthermore, the novel process meets the recent industrial adsorbent requirements such as low activation temperature, high fixed carbon content, high yield, high adsorption properties and high surface area which are the key factors for large scale production of bioadsorbent and its usage.

SEPTICEMIA OF SUBTERRANEAN TERMITES COPTOTERMES CURVIGNATHUS CAUSED BY DISTURBANCE OF BACTERIA ISOLATED FROM TERMITE GUT AND ITS FORAGING PATHWAYS
DESCRIPTION : Microbial pathogens continue to attract a great deal of attention to manage termite population. Every bacterium has its own mode of action and in fact, the mechanisms used by bacteria to attack termites remains elusive at the moment. Hence, the objective of this study was to evaluate the susceptibility of subterranean termites Coptotermes curvignathus to opportunistic pathogens using culturable aerobic bacteria isolated from the termite gut and its foraging pathways. Bacterial suspensions were prepared in concentrations of 103, 106, and 109 CFU/mL and introduced to the termites via oral-contact and physical contact treatment. The data shows that contact method acted slower and gave lower mortality, compared to oral-contact method. C. curvignathus were highly susceptible to Serratia marcescens and Pseudomonas aeruginosa. Serratia marcescens showed the highest mortality percentage of 68% and 54% at bacterial concentration of 109 CFU/mL via oral-contact and contact method, respectively. S. marcescens was also defined as the bacteria with the highest ability to induce high mortality of C. curvignathus with the lowest concentration of bacterial suspension at a given time under laboratory condition. The results of this study indicate that P. aeruginosa and S. marcescens in particular may be attractive candidates worth further examination as a possible biocontrol agent against C. curvignathus in the field and, to evaluate environmental and ecological risks of the biocontrol.
