“…In natural water, the biodegradation rate depends upon the microbial population and amount of xenobiotics [170], and the numbers of the microbes are heavily influenced by the macrophyte species [171]. Plants give organic carbon to microbes present in the rhizosphere that assist them to degrade complex organic compounds [172], such as hydrocarbons and aromatic hydrocarbons [173,174]. Bacteria also release indole acetic acid (IAA) to improve plant growth [175].…”

This article provides useful information for understanding the specific role of microbes in the pollutant removal process in floating treatment wetlands (FTWs). The current literature is collected and organized to provide an insight into the specific role of microbes toward plants and pollutants. Several aspects are discussed, such as important components of FTWs, common bacterial species, rhizospheric and endophytes bacteria, and their specific role in the pollutant removal process. The roots of plants release oxygen and exudates, which act as a substrate for microbial growth. The bacteria attach themselves to the roots and form biofilms to get nutrients from the plants. Along the plants, the microbial community also influences the performance of FTWs. The bacterial community contributes to the removal of nitrogen, phosphorus, toxic metals, hydrocarbon, and organic compounds. Plant–microbe interaction breaks down complex compounds into simple nutrients, mobilizes metal ions, and increases the uptake of pollutants by plants. The inoculation of the roots of plants with acclimatized microbes may improve the phytoremediation potential of FTWs. The bacteria also encourage plant growth and the bioavailability of toxic pollutants and can alleviate metal toxicity.

“…Of importance to maintenance of high beneficial inoculant numbers during phytoremediation is the involvement of PAH deoxygenase in indole-3-acetic acid (IAA) synthesis by bacteria (Mordukhova et al 2000), because this suggests the existence of interplay between the PAH-catabolic and IAA-anabolic pathways to stimulate plant growth. In addition, IAA induces the expression of genes related to bacterial survival under stress conditions (Vande Broek et al 1999;Bianco et al 2006) and may serve as a signaling molecule in bacteria-plant interactions (Lambrecht et al 2000).…”

Rhizobacteria possess a wide variety of qualities governing their pollutant-catabolic and rhizospheric competences. We investigated how the abilities to degrade phenanthrene and other polycyclic aromatic hydrocarbons (PAHs), to synthesize surfactants and the phytohormone indole-3-acetic acid (IAA), to be motile, and to perform chemotaxis toward phenanthrene and some potential root-exudate components were manifested in rhizobacteria isolated from oil-polluted sites. We observed that most of the examined rhizobacteria had the abilities under consideration and that in some strains, these were strongly affected by the bacterial environment. Only one strain-Sinorhizobium meliloti P221-exhibited increased PAH-degrading, surfactant-producing, and IAA-synthesizing activities, as well as distinct behavioral responses. We conclude that S. meliloti P221 can be used as a model to assess the contributions of all these activities to plant-inoculation-induced reduction in the soil PAH contents. This strain also may be useful for phytoremediation applications.

“…Azospirillum fixes nitrogen to the soil apart from that it also synthesis IAA used for plant growth (Jain and Patriquin, (1985). Mordukhova et al (1991) were also supported the Burkholderia isolates produce IAA and cytokinin, growth regulators. Some of the root colonizing bacteria were observed in the production of auxin and cytokinin by Pseudomonas sp.…”

Marine microbes are important sources for recovering bioactive substances. One of the marine isolates, SB2, used a variety of media, with tryptic soy broth showing the best growth and yellow coloring. The largest amount of biomass was produced after 72 hours when the strain SB2 was cultured on glucose, molasses, and peptone, a yeast extract containing carbon and nitrogen sources. Yellow pigment must be extracted using methanol, and the isolate SB2 produced the most of this color. At a concentration of 100 g ml-1 of several bacterial pathogens, the recovered pigment from the SB2 isolate exhibited antibacterial action. The maximum production of IAA and GA is shown in TS broth, which is additionally augmented by the siderophore synthesis of catechol and salicylate. The SB2 also produces IAA and GA. In contrast, the highest level of ACC deaminase activity was found in nutrient broth. Due to the generation of pigment, the strain SB2 may be essential for Plant Growth Promoting Rhizobacteria (PGPR) and antibacterial properties.
