“…This work studied 130 strains of PNSB isolated from ASS at various sites in Southern Thailand and Vietnam. Of these 130 strains, 110 had been previously isolated from acid paddy fields (Khuong et al 2017) and the remaining isolates were from acid sulfate paddy soil in the Mekong delta, Vietnam (Ca Mau Peninsula, Long Xuyen Quadrangle, Hau River Depression and Plain of Reeds areas) (our unpublished data). All PNSB strains were screened firstly for acid resistance, and secondly for resistance to a mixture of aluminum and ferrous compounds, to obtain acid-aluminum-ferrous-resistant PNSB isolates (Khuong et al 2017).…”

“…Additionally, PNSB can grow in different growth modes as photoautotrophs, photoheterotrophs, chemoheterotrophs, and chemoautotrophs (Panwichian et al 2010;Imhoff 2017). They can do so in extreme stress conditions (Imhoff 2017) of acidity or salinity (Nunkaew et al 2015;Khuong et al 2017Khuong et al , 2018. PNSB have been isolated from areas contaminated with heavy metals such as Cd, As, Hg, and Pb (Panwichian et al 2010;Mukkata et al 2015;Nookongbut et al 2016;Sakpirom et al 2017).…”

The PNSB R. palustris and Rubrivivax benzoatilyticus have specifically been proved to resist high concentrations of H + , As 5+ , As 3+ , Al 3+ , and Fe 2+ in acidic soils (Khuong et al 2017;Nguyen et al 2018;Nookongbut et al 2019).…”

Resistance mechanisms of acid Mn 2+-resistant purple nonsulfur bacteria (PNSB) were investigated to determine their ability to alleviate adverse effects of excess manganese on plant growth and productivity in acid sulfate soils (ASS). PNSB were isolated and selected based on their resistance to acid and manganese. Their resistance mechanisms were assessed on the basis of biosorption, bioaccumulation, and plant growth promoting properties. Six PNSB were selected for their resistance to Mn 2+ in acidic conditions (pH 3.5-5.5). They were identified as Rhodopseudomonas palustris strains TLS12, VNS19, VNS32, VNS62, and VNW95, and Rhodopseudomonas harwoodiae strain TLW42. Under aerobic dark and microaerobic light incubating conditions in aqueous solution at pH 4.25 for 30 min, these strains adsorbed Mn 2+ (1500 mg L −1) more effectively with released exopolymeric substances (EPS) than with their biomass. Under both incubating conditions, bioaccumulation of Mn 2+ diminished in the following order: cell wall, cytoplasm, plasma membrane. Scanning electron microscope-energy dispersive X-ray spectrometry (SEM-EDS) found accumulated manganese (0.30-0.67% of total elements) in bacterial cells caused morphological change in the form of wrinkles and bleb-like features on exterior surfaces. All selected strains under both incubating conditions released NH 4 + by N 2 fixing and PO 4 3− by solubilizing phosphate from various P-sources. Siderophores, 5-aminolevulinic acid (ALA), and indole-3-acetic acid (IAA) were also released and pH increased. The studied strains showed potential as bioremediators that could reduce Mn 2+ toxicity using EPS and effectively release nutrients and plant growth promoting substances to improve cultivation and fertility in acidic conditions.

“…Bioavailability is limited in acid soils and the subsequent stunted development of crops contributes to the need for fertilizers (Yang et al, 2013). Among critical factors, phytotoxicity due to heavy metals (mostly Fe, Al and Mn) is the major obstruction to agricultural production on acid sulfate soils (Khuong et al, 2017;Nguyen et al, 2018). Several effective techniques have been applied to overcome this serious problem.…”

To screen acid tolerant purple nonsulfur bacteria (PNSB) isolated from peat swamp forests for their abilities to produce plant growth promoting substances (aminolevulinic acid: ALA, siderophores, indole-3-acetic acid: IAA) and also release ammonium from N2 fixation. Among 10 PNSB isolates grown in basic isolation medium (BIM), pH 4.5 found that strain KKSSR91 was the most effective to release ALA and siderophores under microaerobic light conditions; while strain KTPWG11 exhibited highest production of siderophores under aerobic dark conditions. Based on ALA production in medium containing 60 mM glycine, 4 PNSB isolates were selected for further studies and found that strain KTSSR92 produced highest IAA at 36.9 mg/L. All of them were able to release NH4 + , but no activity to solubilize phosphate. In addition, maximal ALA production in the medium supplemented with glycine by strain KKSSR91 was 2.89 mg/L at 4000 lux light intensity. Seed germination index (GI) of kidney bean (Phasecolus vulgaris L.) test using strain KKSSR91 at 1 g fresh biomass/L, pH 4.5 was 68.81% compared with a control in distilled water as only 58.68%. Strain KKSSR91 was identified using 16S rRNA sequencing and found that it showed 99% similarity with Rhodopseudomonas palustris.

“…These bacteria have been isolated from diverse environments, including marine water [6], river [3], wastewater treatment [7], and domestic wastewater treatment [8]. This group of AAP is also known as potential pollutans bioremediations such as heavy metal [9,10], azo dye [7], and miscellaneous pollutants [11,12,13]. Yogyakarta is one of Provinces in Indonesia which is geographically located in the middle of the plains region flanked by neighboring districts with high character of Mount Merapi slope in the north and coastal areas in the south.…”

Numerical phenetic analysis was used to compare phenotypic data obtained from 6 isolates of pigmented bacteria strains taken from marine and river aquatic. Each strain was tested for 120 characters, analysed using the simple matching (SSM) and Jaccard (SJ) similarity indices with unweighted pair-group method with arithmetic mean (UPGMA) clustering method. All of the strains classified into two clusters, cluster A as marine pigmented bacteria and cluster B as river pigmented bacteria. Differences were observed between the dendrograms derived from the SSM and SJ. Presence of bacteriochlorophyll-a (Bchl-a), carotenoids, as well as other biochemical tests of three marine pigmented strains were in match with key characters of the genera Roseobacter, Roseateles and Erythrobacter. Three of river pigmented strains were identified as Xanthobacter, Flavobacterium and Pseudomonas. It was proved that the marine and river pigmented bacteria isolates showed a relative phenotypically distance. It was clearly seen that the phenetic approach was a necessary tool to delimitate and identify the pigmented bacteria from different habitats.
