The effectiveness of UV and chlorination, used individually and sequentially, was investigated in killing pathogenic microorganisms and inhibiting the formation of disinfection by-products in two different municipal wastewaters for the source water of reclaimed water, which were from a microfilter (W1) and membrane bioreactor (W2) respectively. Heterotrophic plate count (HPC), total bacteria co...

The 3MTM PetrifilmTM Lactic Acid Bacteria Count Plate method is designed for the detection and enumeration of lactic acid bacteria from select food matrices and environmental surfaces. The 3M Petrifilm Lactic Acid Bacteria Count Plate method was evaluated in a method comparison study according to current AOAC® guidelines. The method was compared to the Compendium of Methods for the Microbiologi...

A sampling protocol was developed to examine particles released from granular activated carbon filter beds. A gauze filter/Swinnex procedure was used to collect carbon fines from 201 granular activated carbon-treated drinking water samples over 12 months. Application of a homogenization procedure (developed previously) indicated that 41.4% of the water samples had heterotrophic plate count bact...

Bacteria- and virus-containing aerosols were studied during the late summer and fall seasons in a midwestern suburb of the United States before and during the start-up and operation of an unenclosed activated sludge wastewater treatment plant. The study showed that the air in this suburban area contained low-level densities of indicator microorganisms. After the plant began operating, the densi...

Salt licks are naturally occurring areas in the forest with high concentrations of minerals which supply nutrients to animals and plants their vicinity [1, 2]. Microbes, on other hand, widespread environment, presence always has an influence habitat they thrive. This study was conducted analyse diversity bacteria species water a salt lick area Kapit, Sarawak. The analysis carried out determine ...

Functional foods containing probiotic bacteria (lactic acid bacteria and bifidobacteria) are getting popularity in the world, due to tremendous health benefits conferred by these bacteria. However, the total viable count of bacteria in the final product and the sensory attributes of the product are of higher importance for its consumer acceptability. In this study, flavored (strawberry, pineapp...

Bioluminescence methods have been applied to the measurement of the viable and total cell masses of small samples of dental plaque. The total adenine nucleotide content of dental plaque samples and of a pure culture of bacteria was determined and the adenylate energy charge calculated from this. When a pure culture of bacteria was killed with heat, the adenylate energy charge decreased exponent...

the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...

Although meat and fish are prized delicacy in Nigeria, they can also spread germs that multidrug resistant (MDR). Moreover, research on these MDR bacteria from Awkametropolies is scarce. Thus, the bacteriological characteristics antibiogram profiles of E coli isolated were studied this investigation. Twenty different samples sites gathered microbiologically examined. Standard microbiological pr...

Introduction: Probiotics are defined as live non-pathogenic microorganisms and if administered in adequate amounts, can have beneficial effects on their hosts. This study aimed to isolate Gram-positive bacteria from different sources and to evaluate their probiotic properties. Methods: We obtained five samples from various sources including yogurt, infant feces, cheese, and soil under aseptic m...
