The goals of this study were to predict the genes associated with the biodegradation of organic contaminants and to examine microbial community structure in samples from two contaminated sites.

The study presents chitosan nanoemulsion encapsulating Cinnamomum glaucescens essential oil (CGEO) as a novel green preservative against food born fungi and aflatoxin B1 production in food system. GC–MS analysis suggested 1,8-cineole (46.56%), safrole (17.64%) as major and terpineol (5.88%), 4-terpineol (4.68%), β-pinene (2.08%), β-thujene (2.03%), and linalool (2.02%) as minor components of CGEO.

In today’s agriculture, the use of pesticides has become a necessity for higher yield of crops. Out of the total pesticides applied, only a small fraction reaches the target pest and the rest pollute different environmental segments. The present study signifies the effect of soil moisture and enhanced sunlight intensity on the degradation of dimethoate, a commonly used organophosphate pesticide in soil.

In order to achieve maximum crop yields, the use of fertilizers has become prevalent in the agricultural industry. Chemical fertilizers are a controversial topic where the accumulation of heavy metals is detrimental to soil conditions, as well as in water and air pollution. However, there is little information from investigations on the effectiveness of different fertilizers on seed germination.

The effect of environmental pollutants on living organisms can be assessed by studying the changes in the indigenous microbial community. Therefore, in this study, cultivatable bacterial community in nonpolluted as well as household sewage and industrially polluted water of Lai Nullah flowing through Islamabad and Rawalpindi, Pakistan was analyzed.

Campylobacter is the leading cause of human bacterial gastroenteritis worldwide and has a major impact on global public health. Whole Genome Sequencing (WGS) is a powerful tool applied in the study of foodborne pathogens. The objective of the present study was to apply WGS to determine the genetic diversity, virulence factors and determinants of antimicrobial resistance of the populations of C. jejuni and C. coli in Peru. A total of 129 Campylobacter strains (108 C. jejuni and 21 C.

Listeria monocytogenes is a foodborne pathogen, with relatively low incidence but high case-fatality. Phytochemicals have been recognized as a promising antimicrobial agent as an alternative to synthetic chemicals due to their safety and high efficacy with multi-target sites.

McWhorter Campylobacter jejuni and Salmonella Typhimurium are major foodborne pathogens that cause gastrointestinal infections in humans. Humans can acquire either bacterial species through the consumption of contaminated poultry meat.

Given the significance of food safety, it is highly urgent to develop a sensitive yet reliable sensor for the practical analysis of algal toxins. As most of the developed sensors are disturbed by interfering substances and the target toxin is detected in a single-signal manner based on the immunoassay technology.

Introduction. Salmonella enterica serovar Typhi (S. Typhi) is the etiological agent of typhoid fever. To establish an infection in the human host, this pathogen must survive the presence of bile salts in the gut and gallbladder.

Food security goes beyond food being available; the food needs to be free of contaminants. Trichothecenes mycotoxins, produced by Fusarium fungus, are. among the most frequently found contaminants of wheat. In this study, we evaluated the production of trichothecenes Deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-AcDON), 15-acetyldeoxynivalenol (15-AcDON), and nivalenol (NIV) by Fusarium meridionale, F. austroamericanum, and F.

There is a rapid rise in the incidence of quinolone resistant bacteria in Nigeria. Most studies in Nigeria have focused on isolates from the clinical settings, with few focusing on isolates of environmental origin. This study aimed to investigate the antibiogram and carriage of plasmid-mediated quinolone resistance (PMQR) genes by quinolone-resistant isolates obtained from a pool of cefotaxime-resistant Escherichia coli (E.

Fruit and vegetable natural beverage market is growing around the world, but their intrinsic characteristics lead to a high microbial and enzymatic activity, showing a short shelf life when not treated. The present work aims to evaluate the effect of ultrasound (US) treatments on the main spoilage factors and some quality indicators of a mixed fruit and vegetable smoothie (F&VS).
