“…The observed increase could be ascribed to bacterial dissimilatory nitrate reduction to ammonium (DNRA), also known as nitrate/nitrite ammonification, a not very common process that is the result of anaerobic respiration by chemo-organo-heterotrophic microbes. This process could been performed by naturally occurring bacteria [36]. The nitrate source of nitrogen, significantly decreased, according with previous results obtained by using the same biological system on nitrate rich waters [27].…”

Wastewaters generated by the pyrolytic process require treatments to reduce the risks of contamination in rivers, lakes, and coastal waters. Utilizing constructed wetlands is one of the possible approaches according to a Circular Economy System. Plant Growth-Promoting Bacteria (PGPB) and Arbuscular Mycorrhizal Fungi (AMF) can improve plant growth and enhance the bioremediation of wastewater. Two experiments were set up: in the first, a pilot mesocosm was designed to evaluate the effects of a consortium of AM fungi and a PGPB strain on Phragmites australis. After 60 days, the highest plant growth was obtained after inoculation with the combination of microorganisms. In the second experiment, a constructed wetland was built to remediate wastewaters from gasification plant. The plants were efficient in scavenging biological oxygen demand (BOD5), chemical oxygen demand (COD), total fat and oils, hydrocarbons, phenols, aldehydes, surfactants, fluorides, sulfites, sulfates, nitrate, and phosphorus. These data suggest that inoculation of P. australis with AMF and PGPB strains significantly improve the depuration process of wastewaters from gasification plants via constructed wetlands.

“…Pseudomonas is a member of Gammaproteobacteria belonging to the group of denitrifying bacteria with diverse metabolic abilities (Dados et al, 2015). As reported previously, P. otitidis is used for wastewater treatment (Dahiya & Mohan, 2016), including contaminant removal processes, such as dye degradation and bioremediation in hydrocarbon-contaminated soils (Dados et al, 2015;Wu et al, 2009).…”

The presence of effective bacteria removing nitrite, nitrate, and ammonia in a recirculating aquaculture system (RAS) is necessary to attenuate their toxicity to fish. The research was conducted to find bacteria that can be cultured and reduce nitrite, nitrate, and ammonium. Sixteen bacterial colonies were isolated from bioballs of RAS biofilter and tested for their ability to reduce nitrite or nitrate concentrations. Using a simple indicator paper for nitrite and nitrate, four isolates that reduced nitrite and nitrate concentrations, namely K1NA3, K2NA3, CNA1, and PRO4NA1 were selected. The four isolates were then evaluated for the metabolism of nitrate, nitrite, and ammonium compounds using the spectrophotometry method. Results showed that the isolates K1NA3, CNA1, and PRO4NA1 reduced nitrite concentration but produced ammonium, whereas K1NA3 isolate was able to reduce nitrate concentration but produced both nitrite and ammonium. Experiments in reducing ammonium levels in the synthetic waste media showed the ability of four isolates to reduce ammonium levels after six days despite producing nitrite. Based on the 16S rRNA gene analysis, these isolates have a close relationship to Pseudomonas otitidis (KINA3 and K2NA3), Acinetobacter cumulans (CNA1), and Vogesella perlucida (PRO 4NA1).

“…Pillai et al isolated a hot spring bacterium, called Bacillus subtilis P13, that is able to effectively degrade and grow using chrome shavings (Pillai and Archana, 2012). Due to the high resistance of some compounds to biodegradation, bioagumentation strategies have been studied, (Chen et al, 2017;Dahiya and Venkata Mohan, 2016;Nzila et al, 2016). Bioaugmentation involves the addition of microorganisms that have the ability to biodegrade recalcitrant molecules in a polluted environment (Nzila et al, 2016;Fernendez et al, 2019).…”

The chrome shavings waste obtained as a result of the leather finishing process accumulates in a large volume in tanneries and represent a major problem for the environment. This waste are particularly resistant to attack of microorganisms, due to the significant concentration of chromium and are thus difficult to degrade. In this study, chrome shavings were analyzed microbiologically by determining the total number of germs and the number of yeasts and molds on specific culture media. Several bacterial and fungal strains were isolated from the cultures in Petri dishes, after the growth of the colonies. These strains were characterized in terms of the production of proteolytic enzymes, by a method of screening on the media with casein, which allows the determination of proteolytic indices of microorganisms. As a result of the tests performed, five bacterial strains probably belonging to the genus Bacillus and two fungal strains from the genera Penicillium and Cladosporium were selected.
