“…PUF1 was a Gram-negative, rod, vibrioid or peanut shaped cells. It reported that R. palustris formed rosette-like clusters in older cultures and reproduced as budding [16]. The cell division occurred by budding was also observed (Fig.…”

“…As shown in Fig. 2, cell suspensions under an NH 4 -N concentration ≤1.0 g/L always involved the characteristic absorption peaks at 806 and 866 nm indicating the presence of pigment bacteriochlorophyll a [16], while PUF1s of an NH 4 -N concentration of 6.0 g/L lost all the designated peaks from bacteriochlorophylls and carotenoids over the whole experimental period. Noticeably, suffering a middle NH 4 -N concentration of 3.0 g/L PUF1s restored its pigment synthesis ability after a six-day acclimation period.…”

Though it is feasible of Rhodopseudomonas palustris (R. palustris) stimulation in the cyanobacterial substrate, less is known about its performance under the high ammonium-nitrogen (NH 4-N) circumstance. In the present study, the performance of grown R. palustris Strain PUF1 under an NH 4-N gradient were investigated. Results showed that both the bacterial density and the pigment synthesis were severely inhibited at an NH 4-N concentration of 6.0 g/L, while the ultrathin structure of survived PUF1 wasn't obviously changed in comparison to NH 4-N concentration ≤3.0 g/L. Noticeably, at an NH 4-N concentration of 3.0 g/L PUF1s recovered its biosynthesis of pigments in a six-day acclimation period. Importantly, the PUF1s thrived in algal substrate under the NH 4-N concentration ≤1.0 g/L with per mL algal substrate 8.96 to 9.88×10 8 colony formation unit (CFU) on day six. Moreover, it was more diverse of the bacterial consortia in the low NH 4-N treatments (≤1.0 g/L) than that of NH 4-N concentration 3.0-6.0 g/L. Additionally, the excess NH 4-N reduced the sequestration of phosphorus by PUF1s from the algal substrate. Based on the above findings, an NH 4-N threshold up to 1.0 g/L was recommended, it herein produces substantial R. palustris biomass and achieves efficient nutrient sequestration from the protein-rich cyanobacterial feedstock.

“…Gu et al [45] reported that a methanogenic bacterial consortia derived from marine sediment from Victoria Harbour transformed 3-methylindole to 3methyloxindole, whereas a sulfate-reducing consortium mineralized 3-methylindole completely via 3-methyloxindole and -methyl-2-aminobenzeneacetic acid (Figure 7(c)). Sharma et al [89] isolated a new 3-methylindole-degrading purple nonsulfur bacterium, Rhodopseudomonas palustris WKU-KDNS3, from a swine waste lagoon using an enrichment technique. This bacterium could remove >93% of the total 3-methylindole in the medium by 21 days.…”

Indole and its derivatives, including 3-methylindole and 4-chloroindole, are environmental pollutants that are present worldwide. Microbial degradation of indole and its derivatives can occur in several aerobic and anaerobic pathways; these pathways involve different known and characterized genes. In this minireview, we summarize and explain the microbial degradation of indole, indole-3-acetic acid, 4-chloroindole, and methylindole.

“…There is yet a paucity of quantitative data on their capacity toward semi-volatile organic species such as C 2 –C 5 VFAs, phenolic, and indolic compounds. In fact, the presence of excessive SVOC levels have been recognized as one of the major concerns in: natural gas treatment 25 26 27 28 , animal housing facilities 29 30 31 , and sewage treatment plants 32 33 . Nonetheless, information regarding their treatment approaches is scanty due to their complex physiochemical properties (relative to common VOCs).…”

In this research, we investigated the sorptive behavior of a mixture of 14 volatile and semi-volatile organic compounds (four aromatic hydrocarbons (benzene, toluene, p-xylene, and styrene), six C2-C5 volatile fatty acids (VFAs), two phenols, and two indoles) against three metal-organic frameworks (MOFs), i.e., MOF-5, Eu-MOF, and MOF-199 at 5 to 10 mPa VOC partial pressures (25 °C). The selected MOFs exhibited the strongest affinity for semi-volatile (polar) VOC molecules (skatole), whereas the weakest affinity toward was volatile (non-polar) VOC molecules (i.e., benzene). Our experimental results were also supported through simulation analysis in which polar molecules were bound most strongly to MOF-199, reflecting the presence of strong interactions of Cu2+ with polar VOCs. In addition, the performance of selected MOFs was compared to three well-known commercial sorbents (Tenax TA, Carbopack X, and Carboxen 1000) under the same conditions. The estimated equilibrium adsorption capacity (mg.g−1) for the all target VOCs was in the order of; MOF-199 (71.7) >Carboxen-1000 (68.4) >Eu-MOF (27.9) >Carbopack X (24.3) >MOF-5 (12.7) >Tenax TA (10.6). Hopefully, outcome of this study are expected to open a new corridor to expand the practical application of MOFs for the treatment diverse VOC mixtures.
