Obesity, a major public health concern, contributes to numerous metabolic disorders and increases the risk of chronic diseases such as diabetes and cardiovascular conditions. This study investigates the anti-adipogenic and anti-obesity potential of chickpea extracts, comparing raw and fermented chickpea extracts. Fermentation, using bacterial strains isolated from salted oysters, was optimized with Lactiplantibacillus plantarum (PMS-A6), which showed the highest total polyphenol content (26 °C, pH 6.

Dibutyl phthalate (DBP) is widely used in plastic manufacturing to enhance the flexibility and durability of products. However, DBP is a toxic, persistent environmental pollutant that poses significant risks to ecosystems and human health. This study investigates the DBP degradation efficiency of a mixed bacterial system (MBS) consisting of Serratia sp.

Article Synopsis
  • Di-butyl phthalate (DBP) is a harmful environmental contaminant, and this study explores the use of a specific strain of Bacillus subtilis (LLS-04) for bio-electrodegradation to effectively reduce DBP levels.
  • The bio-electrodegradation method showed a 98.57% reduction in DBP concentration, outperforming other degradation techniques due to enhanced microbial and enzymatic activity.
  • Toxicity assessments indicated that treated effluent from bio-electrodegradation was significantly less toxic than untreated DBP effluent, suggesting its potential for effective bioremediation of phthalate pollution.

Norfloxacin (NFX), a widely used fluoroquinolone antibiotic, poses significant environmental concerns due to its persistence in ecosystems and its potential to foster antibiotic resistance. This study explores the degradation of NFX using a bio-electrochemical system (BES) facilitated by Bacillus subtilis isolated from animal waste sludge. Experimental parameters were optimized to maximize removal efficiency, with the optimal conditions determined as an NFX concentration of 200 mg/L, pH 7, and an applied potential of 1.

Recent attention on the detrimental effects of pharmaceutically active compounds (PhACs) in natural water has spurred researchers to develop advanced wastewater treatment methods. Carbamazepine (CBZ), a widely recognized anticonvulsant, has often been a primary focus in numerous studies due to its prevalence and resistance to breaking down. This study aims to explore the effectiveness of a bio-electrochemical system in breaking down CBZ in polluted water and to assess the potential harmful effects of the treated wastewater.

In the present study, the vanadium pentoxide (VO) nickel-doped vanadium pentoxide (Ni@VO) was prepared and determined for in vitro anticancer activity. The structural characterization of the prepared VO and Ni@VO was determined using diverse morphological and spectroscopic analyses. The DRS-UV analysis displayed the absorbance at 215 nm for VO and 331 nm for Ni@VO as the primary validation of the synthesis of VO and Ni@VO.

Naphthalene (NPT), a widely used household pest repellent and insecticide obtained from crude oil, serves as a toxic pollutant to non-target living matter. The stable and resistant nature of NPT makes it difficult to degrade through the physiochemical processes. The present study investigated the bacterial degradation of NPT isolated from crude oil-contaminated soil.

Antibiotics have revolutionized modern day living with their ability to effectively treat infectious diseases in humans and animals. However, the release of antibiotic compounds into the environment has led to toxic consequences. To reduce this environmental impact, it is important to employ an inexpensive and rational technology to reduce the amount of antibiotics released into the ecosystem.

Enterococcus gallinarum (JT-02) isolated and identified from the animal farm waste sludge was found to be capable of biodegrading p-nitrophenol (PNP), an organic compound used to manufacture drugs, fungicides, insecticides, dyes, and to darken leather. The intention of this study was to optimize the biodegradation by finding the optimal conditions for the specific strain through single-factor experiments. The bacterial strain was grown in Luria Bertani broth and various parameters were optimized to achieve the prime settings for the p-nitrophenol (PNP) biodegradation.

Prolonged exposure to antibiotics would likely favor the development of antibiotic resistance and their gene transfer among bacterial communities that are responsible for enriched antibiotic resistant microbes. Sulfamethoxazole (SFM) is a commonly used antibiotic that is released into the environment through human and animal wastes. Improper degradation of SFM poses severe threats to mankind and all life forms.

In the present study, the wurtzite (WZ) type of zinc oxide (ZnO) nanoparticles were synthesized and functionalized with quercetin (ZnO@Quercetin) for the treatment of ovarian cancer. Initially, the chemical synthesis of ZnO nanoparticles was confirmed with DRS UV-vis spectroscopy and the bandgap of the ZnO revealed that the WZ type of nanoparticles. The electron microscopy analysis showed the hexagonal shape, monocrystalline nature of nanoparticles with an average size of 20-25 nm and the SAED pattern showed the interplanar planes for WZ type nanoparticles.

Pharmaceuticals and personal care products occupy a predominant position with respect to both utility and release into the ecosystem, thereby contributing to environmental pollution at alarming rates. Of the several methods identified to minimize the concentration of PPCPs, nanomaterial based photocatalysis seems to be a potential alternative for it being highly economical and eco-friendly. In this study, we synthesized Nickel zinc ferrite (Ni-ZF) [Ni Zn FeO (x = 0, 0.
