this survey was conducted on 133 egge that they were collected from isphahan markets, eggs are tested for aerobic mesophill bacteria (total count) and 186 eggs were tested for salmonella spp. contamination. the results showed 3000 to 10 million colony per gram bacteria counted in egg samples. the mean colony count was 1693000.7 percentage samples rich to mean colony count. (95% accuracy,sd2.232...

An evaluation of natural zeolite as a microorganism carrier in nitrifying reactors operated in batch mode was carried out. Specifically, the influence of zeolite particle sizes of 0.5, 1.0 and 2.0 mm in diameter on microorganism adherence to zeolite, ammonium adsorption capacity and the identification of microbial populations were assessed. The greatest amount of total biomass adhered was obser...

Microbial contamination commonly occurs in microgreens due to contaminated seeds. This study investigated the decontamination effects of water wash (control), 5% hydrogen peroxide (H2O2), UV-C (36 watts), advanced oxidation process (AOP; H2O2 + UV-C), and improved AOP by combination with microbubbles (MBs; MBs MBs) on microbial loads, seeds’ viability, physio-biochemical properties from corresp...

Introduction: Mold may affect the Indoor Air Quality (IAQ) in workplace dormitories. This study aims to investigate indoor air factors that molds growth a dormitory of an LNG Company Indonesia. Several determinant factors, including relative humidity, general temperature, wet dry velocity, illumination, particulate matter, and carbon dioxide concentration were assessed against microorganism col...
