Abstract

The aim of this study is to find out the kind of hydromacrophyte composition having the highest capability to reduce nitrate-phosphate pollutant and Microcystis growth in phytoremediation media using Equisetum ramosissium, Typha angustifolia and the combination of both. Microcystis were obtained from Sutami reservoir, then being inoculated in a media grown by hydromacrophytes (E. ramosissium, T. angustifolia and both of the hydromacrophytes) in the batch culture system. The number of Microcystis was counted every day within fifteen days. Abiotic factors were observe, including the concentration of nitrate using brucine-colorimetry method and orthophosphate (dissolved phosphate) using stannous chloride-colorimetry method on day 0, 6th, 12th and 15th. The growth rate of Microcystis carrying capacity and orthophosphate-nitrate levels among treatments were analysed by ANOVA test. The results showed that E. ramosissium and T. angustifolia in mono and polyculture techniques had similar potentiality to reduce the nitrate and ortophosphate. The concentrations of nitrate and orthophosphate decreased over 70 % in the 6th day after incubation. All of the treatments were able to reduce the carrying capacity of Microcystis up to 46 % , but the growth rates were similar in all media, that is, around 97-170 cells/L/day. Keywords: Equisetum ramosissium, Microcystis, nitrate, phosphate, Typha angustifolia

Abstract

The study proposed identifying the changes in bacterial community and diversity and exploring the potential correlations among sediments parameters and benthic bacterial communities under different mangrove ecosystems rehabilitation statuses. There were three sites: 1. Banyuurip Mangrove Center (BMC) as a restoration site; 2. Pulau Lusi (PL) as a degraded site; and 3. Kampung Blekok (KB) as natural site. The physicochemical parameters and benthic bacteria from the mangrove sediment of the three locations were observed. The data were analyzed statistically to determine the sites' variation and the correlation between parameters. The results found that the physicochemical parameters among restoration sites varied. Soil organic matter (SOM) in natural and restoration sites was significantly higher than in degraded sites. Cation exchange capacity (CEC), calcium and potassium ions, and soil conductivity of the restoration site were considerably higher than the other sites. According to diversity indices and taxa richness, benthic bacteria in the restoration were the most diverse. Proteobacteria dominated in natural and restoration sites; meanwhile, Firmicutes dominated in degraded site. Sulfurovum aggregans was found abundant in natural and restoration sites; meanwhile, Mesobacillus subterraneus was the dominant species in the degraded site. Furthermore, the bacterial taxa richness was positively correlated with SOM and the bacterial diversity was correlated with CEC and conductivity.
