“…marina and A. phaeobacterium are members of purple sulfur bacteria, oxidizing sulfide, thiosulfate or elemental sulfur as electron donors for photolithotrophic growth under an anoxic condition (Imhoff et al, 1998;Caumette et al, 2004;Kumar et al 2007;Srinivas et al, 2009) . This finding is supported by the study of Mukkata et al (2016) , in which high concentration of H 2 S was assumed by the detection of anaerobic purple sulfur bacteria Allochromatium sp. in shrimp pond.…”

Diversity of the Photosynthetic Bacterial Communities in Highly Eutrophicated Yamagawa Bay Sediments

Yamagawa Bay, located in Ibusuki, Kagoshima Prefecture, Japan, is a geographically enclosed coastal marine inlet, and its deteriorating seabed sediments are under an anoxic, reductive, sulfide-rich condition. In order to gain insight into diversity of anoxygenic photosynthetic bacteria (AnPBs) and their ecophysiological roles in the sediments, three approaches were adopted: isolation of AnPBs, PCR-DGGE of 16S rDNA, and PCR-DGGE of pufM. Among the bacterial isolates, relatives of Rhodobacter sphaeroides were most dominant, possibly contributing to transforming organic pollutants in the sediments. Abundance of Chlorobium phaeobacteroides BS1 was suggested by 16S rDNA PCR-DGGE. It could reflect intensive stratification and resultant formation of the anoxic, sulfide-rich layer in addition to extreme low-light adaptation of this strain. Diverse purple non-sulfur or sulfur bacteria as well as aerobic anoxygenic photoheterotrophs were also detected by pufM PCR-DGGE, which could be associated with organic or inorganic sulfur cycling. The outcome of the present study highlights ecophysiologically important roles of AnPBs in the organically polluted marine sediments.

“…It helps to clarify that AAP bacteria are not strictly restrained within the euphotic layer in surface water. Previous work documented that AAP bacteria of Alphaproteobacteria were present in both water samples and sediments at ratios of 25.7% and 27.8% of all puf M sequences derived from shrimp ponds [28]. The dark condition promoted the accumulation of BChl [29].…”

Aerobic anoxygenic phototrophic (AAP) bacteria are photoheterotrophs that use both organic substrates and solar light for carbon and energy requirements. The prevalence of AAP bacteria and their functional role in biogeochemical cycles were numerously reported in ocean habitats [1][2][3][4]. In most studies, they were defined as an important contributor to the carbon cycle. AAP bacteria could be approximately <1% to 10% of total bacteria in the euphotic zones of marine environments [1,[4][5][6]. The cell size of AAP bacteria was significantly larger than Pol. J. Environ. Stud. Vol. 27, No. 2 (2018), 871-879 AbstractAerobic anoxygenic phototrophic (AAP) bacteria are known functionally as photoheterotrophic microbes. Though numerously reported from ocean habitats, their distribution in freshwater lakes is far less documented. In the present study we investigated the dynamics of AAP bacteria in freshwater plateau lakes. Results revealed a high abundance of AAP bacteria in eutrophic lakes. Moreover, AAP bacteria were positively correlated with TN, TP, and Chl a, but the variations of AAP bacterial proportion to potential total bacteria (AAPB%). Alphaproteobacteria-related sequences dominated lakes Luguhu, Erhai, and Chenghai at ratios of 93.9, 85.4, and 70.6%, respectively, and in total comprised eight clearly defined subgroups. Sequences affiliated with Beta-and Grammaproteobacteria were found to be rare taxa. Additionally, Alkalibacterium-like sequences belonging to Firmutes were assigned. Overall, sequences from Alpha-, Beta-, Gammaproteobacteria, and Firmutes separately comprised of 81.6, 8.8, 0.8, and 4.0%. Our present work revealed extreme dynamics of AAP bacteria in both water columns and non-euphotic sediments of plateau aquatic ecosystems, which consolidated their wide distribution and enhanced adaptation.

“…As numerously reported, purple nonsulfur bacteria (PNSB) are an important subgroup of anoxygenic phototrophs used for waste biodegradation and hydrogen production [7][8]. Rhodopseudomonas palustris (R. palustris) is among the most metabolically versatile microorganisms known and reserves a much larger inventory of degradation genes than current knowledge by genome sequencing [9].…”

Occurrences of harmful cyanobacterial blooms are a worldwide environmental problem in most eutrophic lake ecosystems. But what should be noticed is that cyanobacteria can be used as a useful resource due to the wide range of metabolites they produce. Nutrient partitioning using purple nonsulfur bacteria (PNSB) has the potential to biologically concentrate nutrients. The present study evaluated the kinetics of nutrients released from decomposed field blue green algae (BGA) biomasses. The potential of nutrient acquisition from decomposed BGA biomasses for culturing Rhodopseudomonas palustris (R. palustris) was investigated via fed-batch experiments. Results indicated that R. palustris stimulated in algae substrates with algae biomasses ranging from 3.33 to 10 g/L. Removal efficiencies of N and P in the stationary phase of growth were at least 40% and 95%, respectively, of all the nitrogen (N) and phosphorus (P) released. Additionally, the cellular contents like total lipid and poly-β-hydroxybutyrate (PHB), as well as the fatty acids produced by R. palustris, were consistent. Hence, practice based on the bacterial production for the nutrient recovery from BGA biomasses provides a new insight in field algae disposal. It will lower the chances of secondary pollution due to algae decay and produce giant cells of R. palustris and surely will prosper the industries applying R. palustris.
