Remediation has recently received a lot of attention to combat or deal with contaminated soil, water, or air. There are a few types of remediation technologies, such as microbiological remediation and phytoremediation, in which microbial remediation uses microorganisms as the agent, while phytoremediation uses flowers as the agent. H.psittacorum is a flower with phytoremediation and ecologically favorable potential. The study is aimed at learning more about the microorganisms that could help improve soil and water quality. Microbiological remediation uses microorganisms as the agent, while phytoremediation uses flowers as the agent to overcome contamination problems. H.psitacorum was found to be able to remove copper, zinc, and phosphorus from soil and groundwater. As a result, H.psittacorum’s phytoremediation capacity was measured in soil and root samples. Microorganism awareness within the root pattern increased to 4.4 × 109 cfu/ml, whereas the soil pattern increased to 1.5 × 109 cm/ml. The concentration and identity of bacteria in roots and soil revealed information about these bacteria’s ability to remove pollutants, while the water quality assessment demonstrated H.psitacorum’s potential. These seven bacteria have been identified as having a historical mechanism that has proven to be effective in removing, transferring, and stabilizing pollutants. In addition, a water quality assessment demonstrated H.psitacorum’s phytoremediation potential reduced copper, zinc, and phosphate concentrations in the water from 0.64 to 0.068 mg/l, and 0.513mg/l to 0. The concentration and identity of bacteria in roots and soil revealed information about these bacteria’s ability to remove pollutants.
Phytoremediation is a technology that uses plants to degrade, assimilate, metabolize, or decompose organic matter and pollutants. Critical criteria for plants used for phytoremediation include economic benefits, harvest management, and side-use. This cost-effective plant-based recovery utilizes exceptional plant and microorganism capabilities to focus on environmental elements and compounds and metabolize various molecules in their tissues to decompose elements such as heavy metals, toxic substances, and organic pollutants are the main targets. This study aims to analyze the concentration of Gram-positive and Gram-negative bacteria and identify the bacteria using biochemical assays and commercialized API Kit (Biomerieux, France). Three plant samples of Heliconia psittacorum were analyzed for their root and soil sample which showed the concentration of Gram-positive bacteria is higher compared to Gram-negative bacteria which ranged from 1.9 x 108 to 3.95 x 109, while gram-negative bacteria ranged from 2.25 x 107 to 2.95 x 109. Based on the identification test, seven bacteria were identified. Four gram-negative bacteria are Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa and Chryseobacterium indologenes which are generally bacteria that are common to the environment. Meanwhile, three gram-positive bacteria include Staphylococcus aureus, Staphylococcus xylosus, and Staphylococcus lentus have a high impact on metal degradation in the effluent. In conclusion, the concentration of bacteria is relatively higher in the root area of the plant which dominated by gram-positive bacteria and the bacteria that were identified have a prominent effect on the phytoremediation process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
