“…Bacterial species used in this experiment were the gram-negative bacteria of V. alginolyticus. Titah et al (2019) showed that this species can remove Al from wastewater via a biosorption mechanism. The inoculum of bacteria was prepared overnight (24 h) in a nutrient broth medium (Merck, Germany), harvested with 3000 rpm centrifuge for 15 min (Macario, 2012) and diluted with physiological solution (8.5% NaCl) before application until the initial optical density of 1 Å (approximate cell counts of 9 Log CFU/ml) (Purwanti et al, 2019b).…”

“…Overall, the T1B5% reactor with S. grossus and the addition of 5% (v/v) bacteria during the 28 days of testing showed a low final Al content (526 mg/kg). This finding was due to the biochemical-physiological processes performed by plants and bacteria creating absorption and accumulation mechanism (Krstic et al, 2012;Ngo et al, 2014;Titah et al, 2019). The efficiency of Al removal in soil was calculated on the basis of the Figure 7.…”

“…Bioaugmentation of bacteria to assist the phytoremediation of contaminated soil was proven to increase the pollutant removal efficiency (Ismail et al, 2019;Lebeau et al, 2011;Ojuederie and Babalola, 2017). Vibrio alginolyticus is a gram-negative bacteria and can remove Al up to 59.72% from 100 mg/L initial concentration (Purwanti et al, 2019b;Titah et al, 2019). However, the effect of the addition of this species to enhance the phytoremediation of Al by using S. grossus and T. angustifolia is yet to be explored.…”

This research analyses the performance of bacteria-assisted phytoremediation of aluminium (Al)-contaminated soil using native Indonesian plants namely, Scirpus grossus and Thypa angustifolia. A range finding test (RFT) was carried out for 14 days to obtain the tolerable Al concentration for both plants. A total of 2% and 5% (v/v) of Vibrio alginolyticus were bioaugmented during the 28-day phytoremediation test to enhance the overall Al removal. Result of the RFT showed that both plants can tolerate up to 500 mg/kg Al concentration. The addition of V. alginolyticus to the reactors resulted in a significant increment of Al removal from the contaminated soil (p < 0.05). Such addition of V. alginolyticus increased the Al removal by up to 14.0% compared with that withoutbacteria addition. The highest Al removal was obtained for S. grossus with 5% V. alginolyticus with an efficiency of 35.1% from 500 mg/kg initial concertation. T. angustifolia with 500 mg/kg initial concentration showed the highest removal of 26.2% by the addition of 5% V. alginolyticus. The increase of Al removal by the bioaugmentation of V. alginolyticus was due to the interaction in the plant's rhizosphere. Exudates of both plants provided a good environment for bacteria to live in the root area. Meanwhile, the bacteria increased the bioavailability of Al to be further extracted by plants. Certain mechanisms, such as rhizostabilisation, phytostimulation and phytoextraction, were considered to be the main processes that occurred during the treatment. S. grossus and T. angustifolia displayed promising ability to act as Al hyperaccumulators with bioaccumulation factor values up to 5.308 and 3.068, respectively. Development of the design of the ex-situ soil phytoremediation reactors is suggested as a future research direction because it can significantly enhance the current obtained finding.

“…Around 24% of rivers in Malaysia were also polluted by ammoniacal nitrogen (NH 3 -N) originated from sewage that may include the livestock farming activities and domestic wastewater (Katayon et al, 2008; Ministry of Science Technology and the Environment Malaysia, 2003). These pollutants need to be brought down to permissible limits before the disposal of effluent by maximizing removal of pollutants from domestic wastewater (Manju et al, 1998;Tangahu et al, 2019;Titah et al, 2019). Hence, this paper was aimed at discussing about the design of reed bed system for treatment of domestic wastewater.…”

The reed bed system is one types of phytoremediation technology for removing pollutants from the environment. This technology provides an environmentally friendly approach to treating contamination with competitive cost, compared to the physico-chemical treatment. The design of reed bed system is highly important in order to achieve the highest pollutant removal efficiency. The design of reed bed system affects the natural oxygen transfer from the environment. The reed bed system was proven to have a good efficiency in removing Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Total Dissolve Solid (TDS), Total Nitrogen (TN) and a number of bacteria. In addition to the oxygen transfer from the environment, the interaction among pollutant-plants-medium-microbes also plays a vital role in the removal of pollutant using the reed bed system. It was suggested that the future related research should accommodate the importance of several environmental conditions to the interaction between pollutant, plants, medium and microbes as well as the impact of those interactions on the pollutant removal efficiency.

“…The heavy metal pollution has been recognized as a serious problem because these metals are non-biodegradable elements and they have a great danger to human, animals and plants (He and Chen, 2014;Huang et al, 2016;Gong et al, 2019). Biosorption could be defined as the ability of biological materials such as bacteria (Titah et al, 2019, Titah et al, 2018Purwanti et al, 2019), plants (Ismail et al 2019; Kamaruzzaman et al 2019) and algae (Deng et al, 2007) to adsorb heavy metal ions from aqueous solutions by the physico-chemical pathways of uptake. The conventional treatments used for metals removal, such as chemical precipitation, membrane separation, evaporation, electro winning or resin ionic exchange, could be very expensive, and sometimes not effective enough (Aydın and Bulut, 2008).…”

Biosorption is fast, effective and low cost process. It takes place in a wide range of temperature and it can be used for almost all types of heavy metals. The aim of this study was to investigate the ability of locally collected green macro algae to remove copper, chromium and cadmium from synthetic wastewater. The fresh algae were converted into dry powder as biosorbent. In the investigations, 1 g of macro algae powder was exposed to synthetic waste water contaminated with 10 mg/L concentration of copper, chromium and cadmium in separate exposure for 2 hours. The best removal efficiency for copper, chromium and cadmium were 70%, 80% and 85%, respectively, from the initial concentration of 10 mg/L. While macro algae are abundantly available in marshlands of south Iraq, it can be preferably utilized as biosorbent to remove heavy metals from the industrial wastewater.
