Development of a sustainable water treatment process using biochar as substrate for filtration and coliform removal

The Canadian Journal of Chemical Engineering, EarlyView.
Preparation, modification, and characterization of biochar from woodchips and its application in stream water filtration, evaluated through physicochemical and microbiological analyses. Abstract Global microbial water contamination affects 1.8 billion people, necessitating efficient and sustainable treatment methods.

Rapid Enumeration and Identification of Stressed Fecal Coliforms

Journal of Food Protection, 1979
A rapid (72 h) method for enumeration and subsequent identification of fecal coliforms is described. The procedure consists of plating a food suspension in an agar-repair medium (trypticase soy agar pour plates preincubated at 35 C for 2 h, then overlaid with violet red bile agar) incubated at 45.5 C.

An Overview of Foodborne Risks in Afghanistan

Food Safety and Health, EarlyView.
ABSTRACT Foodborne diseases represent a serious yet underrecognized public health burden in Afghanistan, a country shaped by decades of conflict, weak infrastructure, and limited regulatory capacity. This article provides a comprehensive overview of major foodborne risks in the country, including microbiological hazards, chemical contaminants, and ...

Survival of fecal coliforms and fecal streptococci in storm drain sediment [PDF]

Water Research, 1991
Abstract This study defined major factors influencing the survival of the bacterial indicators, fecal coliforms (FC) and fecal streptococci (FS), in separate storm drain sediments during dry weather periods. FC and FS abilities to survive were determined by field sampling and experimental treatments of laboratory stream models.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Widespread occurrence of fecal indicator bacteria in oligotrophic tropical streams. Are common culture-based coliform tests appropriate? [PDF]

PeerJ
Monitoring of stream water quality is a key element of water resource management worldwide, but methods that are commonly used in temperate habitats may not be appropriate in humid tropical systems.

Release of Sediment-Bound Fecal Coliforms by Dredging [PDF]

Applied Microbiology, 1975
Fecal coliform concentrations increased significantly (F test) in the immediate vicinity of a maintenance dredging operation in the Mississippi River navigation channel. Increased counts were attributed to the disturbance and relocation of bottom sediments by dredging and a concomitant release of sediment-bound fecal coliforms.

Effects of Live and Heat‐Treated Bifidobacterium longum CECT 7347 in Adults With Allergic Rhinitis: A Randomised, Double‐Blind, Placebo‐Controlled Trial

Allergy, EarlyView.
This randomized, double‐blind, placebo‐controlled trial evaluated the effects of live probiotic and HT postbiotic B. longum CECT 7347 in adults with moderate–severe allergic rhinitis. Postbiotic supplementation for 8 weeks significantly reduced CSMS and dSS, exceeding the established CSMS MCID with a 33% greater improvement, when compared to placebo ...

Survival of Fecal Coliforms in Frozen Vegetable Homogenates

Journal of Food Protection, 1982
The resistance to freezing of fecal coliforms isolated from frozen vegetables was compared to that of Escherichia coli isolated from fecal sources. The objective was to see if lower resistance to freezing might explain frozen vegetable samples that contain fecal coliforms but not E. coli .
