Exploring bioluminescence in Aglaonema: Investigating Vibrio campbellii translocation and plant responses under CaCl₂ stimulation.

The feasibility of creating light-emitting plants by immobilizing Vibrio campbellii RMT1 on the rhizospheric zone of Aglaonema sp. 'Banlangngoen' was investigated in depth, including bacteria translocation and plant response. Results from scanning electron microscope showed that an inorganic salt-containing medium affected the root.

Using stacked pot connection of wetland microbial fuel cells to charge the battery: Potential and effecting factor.

In the practical application of wetland microbial fuel cells (WMFCs), suitable designs and stacked connection systems have consistently been employed to increase and harvest power generation. Our study compares different WMFCs designs and demonstrates that the cylinder pot design outperforms the small hanging pot design in terms of electrical energy production. Moreover, power generation from the cylinder pot can be further optimized through separator modification and stacked connections.

Light-emitting plants development by inoculating of Vibrio campbellii RMT1 on the rhizospheric zone of Aglaonema cochinchinense.

The concept of utilizing light-emitting plants (LEPs) as an alternative to traditional electricity-based lighting has garnered interest. However, challenges persist due to the need for genetic modification or chemical infusion in current LEPs. To address this, researchers have investigated the interaction between plants and luminous bacteria, specifically Vibrio campbellii, which can efficiently be translocated into Aglaonema cochinchinense tissues through the roots to produce LEPs.

Exogenous γ-aminobutyric acid and Bacillus pumilus reduce arsenic uptake and toxicity in rice.

In this study, the addition of γ-aminobutyric acid (GABA), Bacillus pumilus, or both, was found to enhance rice growth and yield while significantly decreasing arsenic (As) accumulation in Oryza sativa rice tissues. GABA emerged as a regulator of iron (Fe) homeostasis, acting as a signaling modulator that influenced phytosiderophore secretions in the plant. Meanwhile, B.

Performance evaluation of three constructed wetland-microbial fuel cell systems: wastewater treatment efficiency and electricity generation potential.

Constructed wetlands (CWs) have proven to be effective and environmentally friendly for removing pollutants, while microbial fuel cells (MFCs) offer the potential for electricity generation. Thus, this study evaluated the performance of three CW-MFC systems (zigzag, single-column, and triple-column continuous) for domestic wastewater treatment and electricity generation. Results showed that parallel connection of CW-MFCs significantly improved power generation compared to series connection.

Development of light-emitting Episcia lilacina leaf by applying Vibrio campbellii RMT1 and extending the glowing by CaCl and yeast extract.

Glowing Episcia lilacina was generated through foliar application of the bioluminescent bacterium Vibrio campbellii RMT1. Firstly, different nutrient formulas were tested, incorporating yeast extract and various inorganic salts, such as CaCl, MgCl, MgSO, KHPO, KHPO, and NaCl, in order to enhance bacterial growth and light emission. The combination of 0.

Remediation of algal cells, PO, and NO from eutrophic wastewater using Echinodorus cordifolius in zigzag-horizontal subsurface constructed wetlands.

The pollutant removal efficiency of traditionally constructed wetlands (CWs) is often limited due to low interaction time between wastewater and the CW matrix (plants, microbes, and substrates). A zigzag-horizontal subsurface flow constructed wetland with effluent recirculation (Z-HSSF + ER) was developed to improve removal efficiency. Echinodorus cordifolius plants were used in this study.

Bioremediation of gaseous methyl tert-butyl ether by combination of sulfuric acid modified bagasse activated carbon-bone biochar beads and Acinetobacter indicus screened from petroleum contaminated soil.

Combination of sulfuric acid modified bagasse activated carbon-bone biochar beads and Acinetobacter indicus screened from petroleum contaminated soil was the best condition for gaseous methyl tert-butyl ether (MTBE) removal. It was found that HSO modified bagasse AC in powder form had higher adsorption capacity (989.33 mg g) than that in bead form (1.

Modified coir pith with glucose syrup as a supporter in non-external nutrient supplied biofilter for benzene removal by .

Coir pith glucose syrup beads were used as a supporter in a biofilter system. The modified coir pith beads provided a carbon source and controlled humidity for microorganism growth for long-term operation without external nutrient supplementation. For the screening, spp.

Reducing arsenic in rice grains by leonardite and arsenic-resistant endophytic bacteria.

Arsenic contaminated in rice plants can cause many physiological, biochemical and productivity in rice. This also had a negative impact on human health. To decrease arsenic in grains, a combination of leonardite as amendment and arsenic-resistance endophytic bacteria was investigated.

Enhancing arsenic removal from arsenic-contaminated water by Echinodorus cordifolius-endophytic Arthrobacter creatinolyticus interactions.

In this study, Echinodorus cordifolius was the best plant for arsenic removal compared to Cyperus alternifolius, Acrostichum aureum and Colocasia esculenta. Under arsenic stress, the combination of E. cordifolius with microbes (Bacillus subtilis and Arthrobacter creatinolyticus) was investigated.

Adsorption of Reactive Red 141 from wastewater onto modified chitin.

This research involved the adsorption of synthetic reactive dye wastewater (SRDW) by chitin modified by sodium hypochlorite and original chitin in batch experiments. The comparison of maximum adsorption capacity used the Langmuir model to describe SRDW adsorption onto chitin and modified chitin under a system pH of 11.0.
