“…The significant decline in Cr 6+ concentrations can be attributed to the presence of rhizosphere bacteria in water hyacinth, as no bacteria were identified in the control treatment. The root structure of water hyacinth provides a suitable environment for aerobic bacteria to obtain carbon sources and produce organic compounds for plants (Hasbi et al 2020). The decrease in Cr 6+ concentration in the control may be caused by several special characteristics of water hyacinths such as a dense fibrous root system, wide leaves, and fast growth (Saha et al 2017).…”

“…The decrease in Cr 6+ concentration in the control may be caused by several special characteristics of water hyacinths such as a dense fibrous root system, wide leaves, and fast growth (Saha et al 2017). Absorption of Cr 6+ and water through roots, because the root system induces significant cation exchange through the membrane cell enabling the mechanism of Cr 6+ absorption into the root system (Hasbi et al 2020). On the 21 st day of treatment, the levels of Cr6+ in R2M1 and R1M2 were 1.94 mg.L -1 and 1.44 mg.L -1 , respectively, which were lower than those in the R1M0 treatment at 2.181 mg.L -1 and the R0M1 treatment at 2.528 mg.L -1 (single bacteria).…”

Abstract. Wulandari AD, Meitiniarti VI, Kasmiyati S. 2024. Interaction between Eichornia crassipes with Microbacterium sp. SpR3 and Micrococcus luteus RT-9 in Cr6+ reduction in liquid media. Biodiversitas 25: 957-963. Water Pollution caused by Cr6+ contamination is difficult to remove from the environment. One of the efforts to reduce Cr6+ contamination in water is by bioremediation. Bioremediation using the interaction of rhizosphere bacteria with aquatic plants can be employed to decrease the content of Cr6+ in water environment. This study aimed to determine the effect of adding Microbacterium sp. SpR3, Micrococcus luteus RT-9, and a mixture of both bacteria on the ability of Eichornia crassipes to reduce the concentration of Cr6+ in the growth media and the plant's growth potential. This study was conducted in the Microbiology Laboratory of the Faculty of Biology at Satya Wacana Christian University. Eichornia crassipes plans of similar size were grown in 450 mL of Hoaglands solution with Cr6+ 5 mg.L-1 in a container. The treatment in this study involves the addition of 50 mL (10% of the working volume) of Microbacterium sp SpR3 culture, Micrococcus luteus RT- 9, and a combination of both Cr6+-reducing bacteria. The reduction rate of Cr6+ concentration in the mixture of both types of bacteria reached 88.06%, which was higher compared to the control without the addition of the inoculum (87.08%). The inoculation of both Cr6+ reducing bacteria did not hibit the growth rate of the plants. The ability of Microbacterium sp. SpR3 and Micrococcus luteus RT-9 to reduce Cr6+ in liquid media can be employed in the bioremediation of Cr6+ contaminated wastewater.

Pengaruh Typha angustifolia, Echinodorus paniculatus, dan Ludwigia adscendens terhadap Kinerja Horizontal Sub-surface Flow Constructed Wetland dalam Penghapusan Total coliform dan TSS

et al. 2022

The performance of the Wastewater Treatment Plants (WWTP) in several hospitals is reported low, where the wastewater often does not meet the quality standards so that it has the opportunity to pollute the environment. Horizontal Sub-surface Flow Constructed Wetland (HSSF-CW) is a green and sustainable technology; it can be used as an alternative technology for hospital wastewater treatment. This study aimed to evaluate the performance of HSSF-CW on a pilot-scale in the removal of total coliform (TC) and total suspended solids (TSS), as well as to assess the effect of Ludwigia adscendens, Echinodorus paniculatus, and Typha angustifolia plants on the performance of HSSF-CW using experimental methods. The operational and design strategy adopted was setting the water depth at 0.30 m, maximum hydraulic loading rate of 3.375 m3/day, continuous wastewater recirculation, the use of river sand-gravel media measuring 5–8 mm, as well as setting tight spacing for T. Angustifolia was 53 clumps per m2, L. adscendens 133 stems per m2, and E. paniculatus 13 clumps per m2. The results of this study indicate that the performance of the HSSF-CW system on a pilot-scale planted with L. adscendens, E. paniculatus, or T. Angustifolia has proven to be able to eliminate the TC and TSS parameters of hospital wastewater to match their respective quality standards in hydraulic retention times <2 and 4 days. It can be concluded that T. Angustifolia, E. paniculatus, and L. adscendens positively boost the performance of HSSF-CW in the removal of TC and TSS. However, T. Angustifolia had a better effect than E. paniculatus and L. adscendens on the performance of the HSSF-CW system. Keywords: Constructed wetland, E. paniculatus, Hospital wastewater, L. adscendens, T. angustifolia ABSTRAK Kinerja Instalasi Pengolahan Air Limbah (IPAL) beberapa rumah sakit dilaporkan rendah, dimana air buangannya seringkali tidak memenuhi baku mutu sehingga berpeluang mencemari lingkungan. Horizontal Sub-surface Flow Constructed Wetland (HSSF-CW) adalah teknologi hijau dan berkelanjutan, yang dapat digunakan sebagai teknologi alternatif untuk pengolahan air limbah rumah sakit. Penelitian ini bertujuan untuk mengevaluasi kinerja HSSF-CW skala percontohan dalam penghilangan total coliform (TC) dan total padatan tersuspensi (TSS), serta menilai pengaruh tumbuhan Ludwigia adscendens, Echinodorus paniculatus, dan Typha angustifolia terhadap kinerja HSSF-CW dengan metode eksperimental. Desain dan strategi operasional yang ditempuh adalah pengaturan kedalaman air pada 0,30 m, laju pemuatan hidrolik maksimal 3,375 m3/hari, resirkulasi air limbah secara kontinyu, pemakaian media pasir-kerikil sungai ukuran 5–8 mm, serta pengaturan jarak tanam yang rapat masing-masing untuk T. angustifolia adalah 53 rumpun per m2, L. adscendens 133 batang per m2, dan E. paniculatus 13 rumpun per m2. Hasil penelitian ini menunjukkan bahwa kinerja sistem HSSF-CW skala percontohan yang ditanami L. adscendens, E. paniculatus, ataupun T. angustifolia terbukti mampu menyisihkan parameter TC dan TSS air limbah rumah sakit hingga sesuai baku mutu dalam waktu retensi hidrolik <2 dan 4 hari. Dapat disimpulkan bahwa T. angustifolia, E. paniculatus, dan L. adscendens secara positif mendorong kinerja HSSF-CW dalam penghilangan TC dan TSS. Namun, T. angustifolia memiliki pengaruh lebih baik dibandingkan E. paniculatus dan L. adscendens terhadap kinerja sistem HSSF-CW.

“…O chapéu-de-couro é importante para o paisagismo, várias espécies pertencentes são importadas para países da Europa com essa finalidade [10]. Também, pode ser utilizado na descontaminação de aquíferos poluídos [11,12], uma vez que este demonstra-se eficiente na fitorremediação de chumbo a níveis de traços [13][14][15].…”

Marcadores químicos em espécies de <i>Echinodorus</i> (Alismataceae) utilizadas como chapéu-de-couro

et al. 2021

O nome chapéu-de-couro é dado às plantas pertencentes ao gênero Echinodorus (Alismataceae). São espécies nativas e popularmente utilizadas como diuréticas e anti-inflamatórias. As espécies Echinodorus macrophyllus e Echinodorus grandiflorus têm o uso recomendado pela Farmacopeia Brasileira. Entretanto, devido à plasticidade fenotípica do gênero, a identificação precisa é dificultada, consequentemente, Echinodorus floribundus e Echinodorus subalatus têm sido utilizadas pela população para os mesmos fins. O objetivo foi avaliar marcadores químicos para as espécies Echinodorus floribundus e Echinodorus subalatus e a similaridade química dessas com as espécies descritas na Farmacopeia Brasileira. A triagem fitoquímica revelou presença de fenóis, flavonoides, flavonas, flavonóis, xantonas, esteroides e triterpenoides nos extratos. Porém ambas as espécies apresentaram valores inferiores de flavonoides totais quando comparadas com Echinodorus scaber, descrita na literatura. A caracterização do extrato aquoso foliar em cromatografia líquida de alta eficiência (CLAE-DAD) detectou 118 e 121 compostos em E. floribundus e E. subalatus, respectivamente. Destes, 25 apresentaram espectros UV-Vis característicos de compostos fenólicos. Não foram detectados o ácido chicórico e a isoorientina, marcadores comuns em Echinodorus. Os teores de derivados do ácido o-hidroxicinâmico para E. floribundus e E. subalatus (5,52% e 3,07%, respectivamente) foram superiores ao que é exigido pela Farmacopeia Brasileira. Dessa forma, há diferenças químicas entre Echinodorus floribundus e Echinodorus subalatus e as descritas pela Farmacopeia Brasileira, entretanto, há indícios de potencial farmacológico das espécies estudadas.
