Polyphosphate is a straight chain biopolymer consisting of tens to hundreds of phosphate residues that are linked by high energy phosphoanhydride bonds, polyphosphate plays an important role in the bioremediation process of uranium waste, especially in the process of uranium metal precipitation in bacterial cells. Some bacteria are known to have the potential to interact with uranium through redox transformation and bioprecipitation by releasing inorganic phosphate to bind uranium in the environment. Inorganic phosphate results from degradation of polyphosphates that accumulate in cells. This study aims to determine the ability of uranium-tolerant bacteria to accumulate polyphosphates during their growth phase. Measurements were made in 5 growth phases, namely the lag phase, the logarithmic phase, the beginning of the stationary phase, the stationary phase, and the stationary end. Quantitative analysis of polyphosphate accumulations was carried out using the Olsen & Dean method. The test results are known that the uranium-tolerant bacterial isolat is able to accumulate the most optimal polyphosphate in the stationary phase, especially at the 48th hour and the lowest polyP accumulation is found in the initial stationary phase at the 24th hour.

Kayeli Bay is a water in Buru Regency which has very important value in terms of ecological and economic functions. During its development, the ecosystem in Kayeli Bay bears the burden of pollution, especially heavy metal mercury as a result of the people's gold mining on Buru Island which uses Hg to get pure gold. Hg can accumulate in the environment, especially deposited in the sediments in Kayeli Bay waters. Mangrove plants that generally grow in estuary and coastal environments are a place for sediment accumulation. This plant has the ability to absorb and accumulate heavy metals, one of which is R. mucronata. This study aims to analyze the concentration of heavy metal Hg in mangroves of R. mucronata and sediments, and to analyze the bioaccumulation of heavy metal Hg in R. mucronata in Kayeli Bay, Buru Regency. Samples were taken from 3 stations, namely the Anahoni River Estuary (Station I), the Wailata River Estuary (II Station) and the Waeapo River Estuary (III Station). Each station has 2 sampling points (replicates). Determination of the concentration of Hg metal in the sample using the CV AAS method. The average value of Hg concentration in the roots was higher than the bark and leaves of the mangrove R. mucronata, but the concentration was lower than the sediment and was still below the critical value of Hg for plants. The average value of sediment Hg concentration is still below the sediment quality standard. In this study, R. mucronata mangroves were excluder and phytostabilized, where there was a limitation on the absorption of heavy metal Hg from water and sediment and the most Hg accumulation was found in the roots.
