“…Determination of parameter values in combination with culture‐independent molecular techniques such as denaturing gradient gel electrophoresis (DGGE) and terminal restriction fragment length polymorphism (T‐RFLP) on polymerase chain reaction (PCR) amplified target genes, besides real‐time PCR and fluorescence in situ hybridization (FISH), could allow the association of the determined parameter values with specific species. If parameter values differ for the same species, operational conditions may have influenced the microbial characteristics, for example, one similar microbial community was acclimated to new operational conditions (Kim, ) or different strains of a species had different metabolic characteristics (Lydmark et al, ). The interaction between modellers and microbiologists is, therefore, encouraged in order to keep track of microbial diversity in mathematical modelling, allowing for example model‐based population optimization (Yuan and Blackall, ).…”

A large variety of microbial parameter values for nitrifying microorganisms has been reported in literature and was revised in this study. Part of the variety was attributed to the variety of analysis methods applied; it also reflects the large biodiversity in nitrifying systems. This diversity is mostly neglected in conventional nitrifying biofilm models. In this contribution, a one-dimensional, multispecies nitrifying biofilm model was set up, taking into account the large variety of the maximum growth rate, the substrate affinity and the yield of nitrifiers reported in literature. Microbial diversity was implemented in the model by considering 60 species of ammonia-oxidizing bacteria (AOB) and 60 species of nitrite-oxidizing bacteria (NOB). A steady-state analysis showed that operational conditions such as the nitrogen loading rate and the bulk liquid oxygen concentration influence both the macroscopic output as well as the microbial composition of the biofilm through the prevailing concentration of substrates throughout the biofilm. Considering two limiting resources (nitrogen and oxygen), the coexistence of two species of the same functional guild (AOB or NOB) was possible at steady state. Their spatial distribution in the biofilm could be explained using the r- and K-selection theory.

“…However, this bias had been clearly reported (Saunders et al 2016 ). Furthermore, all the previous studies took aeration tank samples as if they were automatically representative of the whole WWTP and half of them used traditional molecular biotechnology (Chonova et al 2016 ; Flowers et al 2013 ; Hug et al 2005 ; Jiang et al 2016 ; Ju et al 2014 ; Kim 2013 ; Muszynski et al 2015 ; Tuncal et al 2009 ; Wang et al 2016 ). Again, most of the known research work only had its focus on municipal sewage treatment systems (Chen et al 2016 ; Cydzik-Kwiatkowska and Zielinska 2016 ; Ding et al 2017 ; Isazadeh et al 2016 ; Jiang et al 2016 ; Jin et al 2011 ; Ju et al 2014 ; Lu et al 2014 ; McLellan et al 2010 ; Muszynski et al 2015 ; Wan et al 2011 ; Wang et al 2016 ; Xu et al 2017 ; Zhang et al 2012 ; Zielinska et al 2016 ).…”

To investigate the differences in activated sludge microbial communities of different wastewater treatment plants (WWTPs) and understand their metabolic potentials, we sampled sludge from every biological treatment unit of 5 full-scale waste water treatment systems in 3 typical Chinese municipal WWTPs. The microbial communities and overall metabolic patterns were not only affected by influent characteristics but also varied between different biological treatment units. Distinct genera in different wastewater treatment systems were identified. The important microorganisms in domestic sewage treatment systems were unclassified SHA-20, Caldilinea, Dechloromonas, and unclassified genera from Rhodospirilaceae and Caldilineaceae. The important microorganisms in dyeing wastewater treatment systems were Nitrospira, Sphingobacteriales, Thiobacillus, Sinobacteraceae and Comamonadaceae. Compared with the obvious differences in microbial community composition, the metabolic potential showed no significant differences.Electronic supplementary materialThe online version of this article (10.1186/s13568-018-0714-0) contains supplementary material, which is available to authorized users.

“…Ammonia is the most important growth factor for most of the microalgae [20,[78][79][80], where it can heavily effect the distribution of algal communities in specific habitats. High diversity and growth rate of microalgae were recorded in spots like wastewater and stagnant water, containing a high proportion of ammonia.…”

As a renewable energy source, microalgae have wide interest as a potential tool to produce biofuel and bioproducts. Prevailing in the local habitat, indigenous microalgae are more successful for wastewater treatment processes. Integrated microalgae-based biofuel and bioproduct production with wastewater treatment is a successful practice of modern research. This report describes the isolation and identification of 61 microalgal strains from lakes, springs, ponds, creeks, and rivers of the gigantic area of Malakand, Pakistan. Our study involves the seasonal existence of Chlorophyta in the area, with most dominant flora identified in the summer season followed by spring, autumn, and winter seasons, respectively. The highest ratio of microalgae was found in stagnant waters followed by slow-running water and running water, respectively. However, algal species were reported from all water bodies throughout the year. Commercially important genera like Chlorella, Scenedesmus, and Chlamydomonas were also reported,
