Exorbitant signatures of pesticides and pharmaceuticals in municipal solid wastes (MSWs): Novel insights through risk analysis, dissolution dynamics, and model-based source identification.

Studies on the occurrence and fates of emerging organic micropollutants (EOMPs) like pharmaceuticals and pesticides in MSWs are scarce in the literature. Therefore, MSWs were sampled from 20 Indian landfills and characterized for five widely consumed EOMPs (chlorpyrifos, cypermethrin, carbofuran, carbamazepine, and sodium diclofenac), physicochemical, and biological properties. The pesticide (median: 0.

Earthworm stocking density regulates microbial community structure and fatty acid profiles during vermicomposting of lignocellulosic waste: Unraveling the microbe-metal and mineralization-humification interactions.

Earthworm-induced microbial enrichment is the key to success in vermitechnology, yet the influence of initial earthworm stocking density on microbial community profiles in vermibeds is unknown. Therefore, vermicomposting of lignocellulosic feedstock was performed with different stocking densities of two earthworms (Eisenia fetida and Eudrilus eugeniae) compared with composting. Eventually, earthworm growth, microbial (activity and community profiles), and physicochemical dynamics were assessed.

Eco-geological consequences of textile processing wastes: Risk assessment, elemental dissolution kinetics, and health hazard potential.

Although substantial quantities of toxic wastes are generated from textile industries, the characteristics of textile processing wastes (TPWs) have yet scantily been investigated from ecological and agricultural perspectives. Here, the eco-geological consequences of TPWs are evaluated by considering three types of sludges (i.e.

Pulsed-field gel electrophoresis fingerprinting of isolates recovered from foods of animal origin and fishes in North-Eastern India.

is a pathogen of great concern to the food industry. The present study was aimed to explore the clonal relationships amongst strains isolated from foods of animal origin (milk, beef, chevon (goat meat), pork and chicken) and fish. Forty-seven strains were characterized by pulsed-field gel electrophoresis (PFGE).

Epigenetic regulations enhance adaptability and valorization efficiency in Eisenia fetida and Eudrilus eugeniae during vermicomposting of textile sludge: Insights on repair mechanisms of metal-induced genetic damage and oxidative stress.

Genotoxicity-based assessments of vermitechnology for textile-sludge valorization have rarely been attempted. Therefore, waste sanitization and epigenetic stress-regulation efficiency of Eisenia fetida and Eudrilus eugeniae were evaluated in silk (DSPS) and cotton (CPWS) processing sludge-based vermibeds. Vermicomposting resulted in greater C, N, and P recovery than composting.

Vermiremediation of cotton textile sludge by Eudrilus eugeniae: Insight into metal budgeting, chromium speciation, and humic substance interactions.

Information on prospective metal remediation by Eudrilus eugeniae during vermicomposting of cotton textile sludge (CTS) is rather scarce. This investigation, therefore, evaluates the sanitization efficiency of this species in CTS and CTS + cow-dung (CD) based feedstocks against aerobic composting. Accordingly, reduction in Pb, Cd, Cr, and Zn concentrations was between 50 and 70% under vermicomposting.

Identification of a novel cluster of PCV2 isolates from Meghalaya, India indicates possible recombination along with changes in capsid protein.

Documentation of the emergence of Porcine circovirus 2 (PCV2) infection and economic losses incurred due to high mortality has been reported worldwide. The prevalence and genetic diversity of the virus has been reported in Northeast India including the possible chances of Classical swine fever virus (CSFV) vaccine failure in pig population in this region resulting in major disease outbreak. Irrespective of the genetic variability, the emergence of a novel cluster (based on the ORF2 phylogeny) was reported last year.

Selective detection of fluoride via amplified donor-acceptor interaction of 6H-indolo[2,3-b]quinoline.

In this report, 6H-indolo[2,3-b]quinoline (hereafter 2a) was synthesized and employed as an optical chemosensor for fluoride. The sensitivity of 2a towards fluoride was established from the change in both the absorption and emission signals. The various in-situH NMR, UV-Vis, and density functional studies indicate that the 1:2 binding interaction between 2a and fluoride followed by deprotonation to its corresponding di-anion (2a), which in turn boosted the donor-acceptor interaction between indole and quinoline moiety in 2avia expansion of torsion angle by 10.

Novel boronic acid derivatives of bis(indolyl) methane as anti-MRSA agents.

Towards the search for a new generation of antibiotics to control methicillin-resistant Staphylococcus aureus (MRSA), the design and synthesis of various bis indolyl methane (BIM) derivatives based on their different electron donor and acceptor properties of the substituents have been made, in which boronic acid derivatives of BIM are found to be active against MRSA. The observed evidence with the lead compound reveals their strong anti-MRSA activity, which paves the way of design and further development of a new generation antibiotics.

Pd/Ag-Catalyzed Room-Temperature Reaction of γ-Hydroxy Lactams: Mechanism, Scope, and Antistaphylococcal Activity.

The present work reports a Pd/Ag-promoted amidoalkylation reaction involving various γ-hydroxy lactams and C/O/S nucleophiles at room temperature. The dual mode of activation of both the electrophile and nucleophile by in situ generated catalytically active cationic Pd species facilitates the reaction at room temperature. Among the synthesized isoindoline derivatives, three compounds are found to be active against vancomycin and methicillin-resistant S.

Complete genome sequence of emerging porcine circovirus types 2a and 2b from India.

We report here the first characterized complete genome sequence of porcine circovirus types 2a and 2b from northeastern states of India. These isolates may serve as a potential reference for the Indian strains of porcine circovirus types 2a and 2b.

Pd(II) coordinated deprotonated diphenyl phosphino amino pyridine: reactivity towards solvent, base, and acid.

The reactivity and stability of P(III)-N and P(III)≈N bonds will be different towards various solvents, bases, and acids because of their difference in bond strength due to different N-pπ-P-dπ donor bonding. For this, a P≈N containing Pd(II) complex, [Pd(DPAP)2] (C1), was synthesized from the reaction between PdCl2(COD) (COD = 1,4-cyclooctadiene) and 2 equiv. DPAP (diphenyl phosphino amino pyridine) ligand, followed by deprotonation of the N-H proton of the coordinated DPAP.
