“…Both the genus Thiobacillus and the genus Flavobacterium are composed of denitrifying bacteria. The genus Thiobacillus are the main degraders of thiocyanate, have a strong denitrification capacity, and are commonly used in coking wastewater treatment . The genus Flavobacterium is able to perform heterotrophic nitrification and metabolize refractory organics under elevated dissolved oxygen .…”

To explore the influence of seasonal and regional environmental factors on the bacterial community composition (BCC) and diversity in the sediments of Lake Bosten, the 16S rRNA gene of sediment bacteria in four samples from the lake center area and the macrophyte-dominated area were sequenced using 454 pyrosequencing.According to the operational taxonomic units (OTUs), diversity index, relative abundance, and redundancy analysis (RDA) of the bacteria, the results showed that (i) the bacterial diversity of the lake center area was lower than that of the macrophytedominated area, and it was higher in winter than that in summer as a whole; (ii) seasonal factors and geographical changes had obvious effects on the abundance of dominant bacteria, including Proteobacteria and Firmicutes; (iii) a large number of unclassified bacteria were detected in this study, and the dominant unclassified genera in both lake areas included unclassified Sva0485, unclassified Anaerolineaceae, and unclassified Nitrospiraceae; and (iv) TN and TOC were the main environmental factors influencing the sediment bacterial community in Lake Bosten, as determined by RDA analysis. The study provides a reference for the in-depth understanding the impact with the change of time and space on sediment microbes in Lake Bosten.

“…Alphaproteobacteria and the unclassified members of the Proteobacteria constitites 16.41% of the total members at species level in the present study. Pseudomonas alcaligenes occurrs very rare and is involved in bioremediation of polluted sites [25]. Microorganisms such as alcaligenes sp induces beneficial response to plants when present in soil.…”

Constructed wetlands are ecofriendly, cost effective technology involved in treatment of wastewaters. The goal of this study is focused on characterization of microbial community existing in constructed wetland system planted withCyperusalternifoliustreating sewage contaminated with heavy metals. The characteristics of effluent met the standards of discharge for inland use and irrigation. Microbes in constructed wetland apparently play a pivotal role in the efficiency of system for removal of organics, nutrients, suspended solids and heavy metal. To expose the active players in the lime light, a representative soil sample from the reed bed was collected and characterized for microbial community analysis. Metagenomic studies of the bacterial and fungal flora were identified. Results revealed that the phylum Proteobacteria (38.27%) and Ascomycota (77.47%) dominated in the bacterial and fungal kingdom respectively. However, in the bacterial kingdom at species level major portion remain unclassified exceptPseudomonasalcaligenesbut in the fungal kingdom at species level only 3.1% remain unclassified. The role of bacteria in wastewater treatment is exemplified in previous reports but the role of fungi in wastewater system needs exploration. However, the findings reveal that the identified microbes might have definitely played a vital role in wastewater treatment. The database available for the identification of bacterial species remain undiscovered for a major portion and requires up gradation. Next generation sequence being a high end technology in microbial ecology decodes the entire community in environmental samples but lack of database limits the identification. Implementation of improvements in the paucity of data bases is essential.

“…The positive role of Actinobacteria has been unequivocal for waste water treatment and heavy metal removal from the polluted sites (Wagner and Loy ; Ma et al . ). An increase in 5·7 and 3·1% bacterial OTUs for Firmicutes and Actinobacteria recorded in Bio‐ball treated water might be associated with water remediation.…”

This study aimed to characterize the bacterial communities in rearing water treated with commercial plastic biological ball filters named as Bio‐ball in marron culture for 60 days. Inclusion of Bio‐ball in the aquaculture tanks showed improvement in water quality parameters and enrichment of bacterial communities in terms of operational taxonomic units. The water treated with Bio‐ball showed significantly less nitrate, nitrite, ammonia, phosphorus and high dissolved oxygen concentration than untreated control group. At phylum level, Proteobacteria was dominant in both control and treated water, whereas Firmicutes was found to be significantly (P < 0·05) enriched in Bio‐ball treated water. Among the classified genus, Aquabacterium and Polunucleobacter were most dominant in control and Bio‐ball treated water respectively. Linear Discriminant Analysis Effect Size exhibited 31 indicator bacterial genus, 10 in control and 21 in treated condition, suggesting the enrichment of microbial lineages with addition of Bio‐ball. The bacteria Haliscomenobacter, Hypnocyclicus, Pajaroellobacter and Vibrio were found to be significantly (P < 0·001) correlated with higher pH, nitrate, nitrite, phosphorus and ammonia in control tanks, whereas Corynebacterium was linked to higher temperature in treated water. Overall results suggest that Bio‐ball filter media significantly improved the water quality and microbial populations in aquaculture tanks. Significance and Impact of the Study The results of this study revealed the positive impacts of Bio‐ball in enrichment of microbial flora associated with the degradation process of nitrogenous and organic compounds. Bio‐ball also showed the capability to prevent the colonization of harmful bacteria, and favoured the growth of beneficial microbes in aquatic system. This study therefore could pave the ways of increasing the aquaculture production by improving the water quality.
