The likeness of microorganisms including bacteria, yeast, algae, fungi, and even viruses toward metals is well-known. Higher tolerance to toxic metals has opened up new avenues of designing microbial fabricated nanomaterials. Their synthesis, characterization and applications in bioremediation, biomineralization, and as a chelating agent has been well-documented and reviewed. Further, these materials, due to their ability to get functionalized, can also be used as theranostics i.e., both therapeutic as well as diagnostic agents in a single unit. Current article attempts to focus particularly on the application of such microbially derived nanoformulations as a drug delivery and targeting agent. Besides metal-based nanoparticles, there is enough evidence wherein nanoparticles have been formulated using only the organic component of microorganisms. Enzy...

Nitrogen and Phosphorus work like a hazardous nutrient compound causing acidification of the soil, acid rainfall, eutrophication, and toxicity. The abundance of nitrogen decreases the level of other minerals and imbalances toxic elements such as aluminium which can spread and cause harm to plants and also fish in rivers. The primary mechanisms of removal, treatment and process are described elaborately in this work. This paper highlighting the different techniques, such as whole cells-based removal, immobilisation-based methods, photobioreactor, Bio-CAST-based technology, pilot-scale biological nutrient removal technology, bio-electrochemical system, membrane bioreactor, enhanced allure-type biological system, fresh and marine water microalgae biomass, hetero-photoautotrophic two-stage cultivation, sequential adaptation, deceleration-stat technique and their removal efficiency, are discussed in detail separately. Therefore, suitable economical and optimized methods are needed globally to maintain a balanced nutrient level. This work describes the key issues related to the nitrogen and phosphorus recovery.

The treatment involved As-oxidizing microbes aimed of transforming the more toxic As (III) to less toxic As (V) in the soil. FeCl3 was added at three different concentrations (1, 2, and 3%) to stabilize the As (V). Leaching of the treated soil was investigated by making a soil column and passing tap water through it to determine solubility. Experimental results indicated that the bacterial activity had a pronounced positive effect on the transformation of As, and decreased the soluble exchangeable fraction from 50 to 0.7 mg/kg as compared to control and from 50 to 44 mg/kg after 7 days of treatment. FeCl3 also played an indispensable role in the adsorption/stabilization of As in the soil; 1 and 2% FeCl3 strongly influenced the adsorption of As (V). The soil leachate contained negligible amount of As and trace metals, which indicates that c...

Degradation was routinely monitored by observing growth analysis, chloride release assay, and ring cleavage activity and was further confirmed by gas chromatography (GC) analysis. The bacterium was found to degrade up to 90% of 2,4,6-TCP at 1.5mM concentration. The bacteria were characterized morphologically, biochemically, and by 16S rRNA gene sequencing, which showed 99% sequence similarity with Shigella sp. This is the first report that Shigella sp. was able to degrade 2,4,6-TCP. This strain was found to be novel and a potential 2,4,6-TCP degrader. Further, this strain may be used for bioremediation of 2,4,6-TCPcontaining waste in the environment.

HF-PSF is associated with high morbidity and mortality. A recent study demonstrated that, although survival improved significantly over time among heart failure patients with reduced ejection fraction, there was no such trend toward improvement among patients with HF-PSF. There exists an urgent need to develop effective treatment strategies, specifically for patients with HF-PSF. Current therapeutic recommendations for HF-PSF are aimed at the symptomatic management as well as the treatment of concomitant comorbidities, including hypertension, atrial fibrillation and myocardial ischemia. In spite of two large, recent studies evaluating therapies for HF-PSF, no specific strategies have been proven to substantially benefit outcomes in patien...

A deeper understanding of how biofilms form, develop and interact will help to decipher their roles in promoting and inhibiting corrosion, thus in controlling it. The present review explores most mechanisms of biofilm development and maintenance with particular emphasis on the roles of the biomolecules characteristic of biofilms, including exopolysaccharides (EPSs), proteins/enzymes, lipids, DNA and other metabolites in the corrosion process. These biomolecules play a significant role in the electron transfer process resulting in corrosion induction and inhibition. Microbial attachment, biofilm formation, the EPS matrix and both positive and negative effects by specific biofilm-forming genes all play roles in the electron transfer process. The current review describes these roles in detail. Although challenging to understand and control, the potential of biomolecules in the corrosion process is huge, and the coming...

(BK1) and Aspergillus sp. (BK2). Effluent was collected from the beverage industry (initial concentration of nitrogen were 3200 ± 0.5 mg/L and 4400 ± 0.6 mg/L whereas phosphorus were 4400 ± 2 mg/L and 2600 ± 1 mg/L in treated and untreated effluent correspondingly). Further, the BK1 and BK2 exhibited high removal competence after 1 week of incubation; BK1 removed phosphorus 99.95 ± 0.7% and BK2 95.69 ± 1% in treated effluent while nitrogen removed about 99.90 ± 0.4% by BK1 and 81.25 ± 0.8% by BK2 (initial concentration of phosphorus 4400 ± 2 mg/L and nitrogen 3200 ± 0.5 mg/L). Next, in the untreated effluent BK1 removed 99.81 ± 1% and BK2 99.85 ± 0.8% of phosphorus while removed nitrogen 99.93 ± 0.5% by BK1 and 99.95 ± 1.2% by BK2 correspondingly, (initial concentration of phosphorus 2600 ± 1 mg/L and nitrogen 4400 ± 0.6 mg/L).

CL7 by 16s rRNA gene sequences analysis. This isolate degraded 2,3,4,6-TeCP as indicated by stoichiometric release of chloride and biomass formation. High pressure liquid chromatography (HPLC) analysis showed that Pseudomonas sp. (CL7) was able to mineralize a higher concentration of 2,3,4,6-TeCP (600 mg/l or 2.5 mM) than any previously reported 2,3,4,6-TeCP degrading bacteria. As the concentration of 2,3,4,6-TeCP increased from 50 (0.21 mM) to 600 mg/l (2.5 mM), the reduction in the cell growth was observed and the 2,3,4,6-TeCP degradation was more than 85% in all the concentrations in the present study. CL7 was able to remove 100% of 2,3,4,6-TeCP from the sludge (in Vitro condition) when supplemented with 100 mg/l (0.42 mM) of 2,3,4,6-TeCP and grown for two weeks. This study showed that CL7 can be used for bior...
