Abstract
Abstract. Zeolites are aluminosilicates widely used as ameliorant in oil palm plantation especially on peatland. The zeolite mineral is known to have an excellent molecular sieve property which enables it to hold organic carbon compounds, CO2, and water leading to its potential use for carbon sequestration. Moreover, bioactivated zeolite with
bacterium producing exopolysaccharides could promote the formation of peat molecular structure and their configurations that related to water and nutrient supply for plant. The objective of this study is to characterize natural zeolite clinoptilolite type from Bayah, Banten as exopolysaccharide bacterial carrier for peat ameliorant and reduction
of carbon emission. The physical-chemical characteristics of 60–80, 80–100, and 100–150 particles mesh of zeolite were determined using standard analytical procedures. Furthermore, separation capability of a zeolites sample for carbon dioxide (CO2), NH3, and N2 was measured by temperature programmed desorption (TPD). The Brunauer-Emmett-Teller (BET) technique was used in order to estimate the specific surface area of zeolite while the relative crystallinity of the samples was estimated by comparing their X-ray diffraction (XRD) pattern. The morphology of the samples was investigated by field emission scanning electron microscopy. Total exopolysaccharide bacteria in the matrix of zeolite were counted using total plate count in ATCC 14 media. The results indicated that 100–150 particle mesh of natural clinoptilolite Bayah zeolite has excellent properties of porous structure which contribute to carbon and N2 adsorption, water retention, and bacterial carrier.
