“…The alternating anaerobic (anoxic) and aerobic operation strategy applied in our reactors selects for mixotrophic bacteria (e.g., denitrifiers), while the anaerobic pulse feeding favors bacteria that can accumulate storage polymers. It is estimated that 75% of the activated sludge bacteria are capable of producing storage polymers (Inoue et al, 2016), for example Acidovorax, Chryseobacterium, Comamonas, Dechloromonas, Flavobacterium, Meganema, Paracoccus, Rhodoferax, Simplicispira, Sphingopyxis, Thauera , and Zoogloea (Kragelund et al, 2005; Oshiki et al, 2008; McIlroy et al, 2015; Inoue et al, 2016). Many denitrifying bacteria can produce PHA, and our results suggest that the operating conditions in R3 may have favored PHA production over denitrification.…”

“…In addition, the identification of the weakest points in the process for implementation at industrial scale revealed the next research lines (Muhammadi et al, 2015;Chen et al, 2015a;Kaur and Roy, 2015;Liu et al, 2015). In 2016, authors had maintained attention on the improvement of genotypes and operational conditions of fermentation (Kawaguchi et al, 2016;Tai et al, 2016;Inoue et al, 2016). The integration of the PHA production into other industrial processes, use of mixed cultures and use of waste streams as a source of organic matter have been considered as main research lines (Anjum et al, 2016;Valentino et al, 2017;Koller et al, 2017;Jian et al, 2016;Mohan et al, 2016).…”

“…Table 1 shows that most authors have focused on reducing the cost of the PHA production process. Different strategies have been used to reduce costs such as genetic studies Liu et al, 2015;Tai et al, 2016;Inoue et al, 2016); and optimization of the PHA purification/extraction step (Mohammadi et al, 2012;Liu et al, 2015;Kawaguchi et al, 2016); to obtain PHA compounds with higher economic value and/or promising new applications (Muhammadi et al, 2015;Anjum et al, 2016;6 2015; Mohan et al, 2016;Obruca et al, 2015); to re-use the bacterial biomass generated from PHA production (Wei et al, 2015); to reduce the energy consumption of the PHA production process (Mohammadi et al, 2012;Liu et al, 2015), integration into biorefinery systems (Jiang et al, 2016), and to improve the yield of PHA production (Liu et al, 2015;Kawaguchi et al, 2016).…”

“…Clone library analysis targeting the phaC genes, which encode the class I and II PHA synthase, was employed for analyzing the composition of PHBAMOs. PCR amplification of phaC genes was conducted using the CF1 and CR4 primer set as described previously 19) . The PCR products were purified with a NucleoSpin Extract II kit (Macherey -Nagel, Düren, Germany), and then purified and concentrated by ethanol precipitation.…”
