“…The abundance of Alphaproteobacteria was the highest in the four samples A1, A2, B1, and B2, which were 26%, 23%, 23%, and 27%, respectively, followed by Gammaproteobacteria, which were 13%, 11%, 11%, and 6%, respectively. Proteobacteria is the most common of the Phylum bacteria, including many nitrogenfixing microorganisms and some pathogenic bacteria [51]. The relative abundance of Proteobacteria in constructed wetlands was the highest, which was consistent with the experimental results [52][53][54].…”

“…The Proteobacteria are important bacterial flora which promote contaminant removal in water treatment [55]. In the experiment, the proportion of Proteobacteria in constructed wetlands without microorganisms increased gradually after a period of operation, which may be caused by the low-temperature resistance of Proteobac- Proteobacteria is the most common of the Phylum bacteria, including many nitrogenfixing microorganisms and some pathogenic bacteria [51].

In this study, a novel lab-scale biofortification-combination system (BCS) of Oenanthe javanica and Bacillus series was developed to improve the treatment ability of vertical subsurface flow constructed wetlands (VSFCW) at low temperatures (0–10 °C). The results showed that BCS-VSFCW overcame the adverse effects of low temperature and achieved the deep removal of nutrients. In addition, the removal rates of chemical oxygen demand (COD), ammonia nitrogen (NH4+-N), total nitrogen (TN), and total phosphorus (TP) by BCS-VSFCW were 38.65%, 28.20%, 18.82%, and 14.57% higher than those of blank control, respectively. During the experiment, Oenanthe javanica and low temperature tolerant Bacillus complemented each other in terms of microbial activity and plant uptake. Therefore, VSFCW combined with Oenanthe javanica and low temperature tolerant Bacillus has a promising future in low temperature (<10 °C) areas of northern China.

Significance and Impact of the Study: We investigated the intestinal microbiota (IM) of Quasipaa spinosa tadpoles at four key stages during metamorphosis using high-throughput sequencing of the 16S rRNA gene. Our results showed that the composition of the IM at different development stages and different ages differed markedly, but the differences were not significant among different development stages at 150 days post-hatch. These results indicate that the developmental stage and length of development significantly affect the IM composition of Q. spinosa.

“…Delftia tsuruhatensis was reported in terephthalates degradation [ 32 ]. At the same time, both microorganisms have had an important role in the metabolism and reduction of aromatic pollutants, such as anilines [ 33 ] or bisphenol S [ 34 ]. Rubber tires contain polycyclic aromatic hydrocarbons (PAH) which have been found in recycled rubber tires [ 10 ].…”

Tire Ground Rubber Biodegradation by a Consortium Isolated from an Aged Tire

et al. 2022

Rubber is a natural product, the main car tire component. Due to the characteristics acquired by this material after its vulcanization process, its degradation under natural conditions requires very long times, causing several environmental problems. In the present work, the existence of a bacterial consortium isolated from a discarded tire found within the Socabaya River with the ability to degrade shredded tire rubber without any chemical pretreatment is explored. Taking into consideration the complex chemical composition of a rubber tire and the described benefits of the use of pretreatments, the study is developed as a preliminary analysis. The augmentative growth technique was used, and the level of degradation was quantified as a percentage through the analysis of microbial respiration. Schiff’s test and the use of comparative photographs of scanning electron microscopy (SEM) were also used. The consortium using next generation genetic sequencing was analyzed. A 4.94% degradation point was obtained after 20 days of experimentation, and it was found that the consortium was mostly made up with Delftia tsuruhatensis with 69.12% of the total genetic readings of the consortium and the existence of 15% of unidentified microbial strains at the genre level. The role played by the organisms in the degradation process is unknown. However, the positive results in the tests carried out show that the consortium had action on the shredded tire, showing a mineralization process.
