Click here to read how Jarvis et al. explain that spiral plate method requires only 31% of the labor necessary for the drop count method. IUL’s Spiral Plater: Eddy Jet 2W This rapid plating consists of inoculating a known volume of liquid sample on the surface of a rotating agar plate. ...

If you work in a microbiology laboratory, whether in the field of environment, pharmaceutical, cosmetics, food and beverage, or personal care, your daily work will include colony counting. This can quickly become an exhausting task for microbiologists, as the counting process requires lots of time and concentration, without mentioning the tedious ...

Once your dilution is done with accuracy, your solution is ready to go through homogenization, then inoculation and colony counting. Did you know that IUL provides automated solutions for microbiological laboratories that make the workflow effortless? You can discover our automated instruments such as paddle blender, spiral plater, and automatic ...

Next, accurate volumes of air are sampled by forcing them towards the Petri plate’s agar surface. After incubation, colony counting enables evaluating microbial air quality. An air sampler for every need IUL has different types of air samplers to fulfill every need: Spin Air: Spin technology for precision, accuracy and resolution enhancement. ...

Microbiological examination of various foods indicates that the paddle blender releases a significantly large number of viable microorganisms that are calculated on the basis of colony count than other methods of homogenization, except samples of cheese and powdered egg and milk. ...

Then, thanks to that automatic counter, they finish the process, counting the colonies present in a plate, in seconds: “Just to be able to put it on the plate and let it run on the Eddy Jet, it just makes it so much easier. ...

Logarithmic modes are the most used in spiral plating to perform viable bacteria/fungal counts. Linear and proportional distributions: these types of distributions create hyperbolic concentration gradients that are more moderate than the exponential modes ones. ...

A high dose (20mg/l) of ozone effects sanitisation within a few hours, reducing colony forming unit count (CFU), and Total Organic Compounds (TOC). Because it ultimately converts into oxygen and water, ozone does not introduce any breakdown products into the water as other sanitising agents do. ...
We analyzed the microbial load of 54 holy water samples, repeatedly taken in five Roman Catholic churches in the greater area of Villingen-Schwenningen, Germany, by means of aerobic colony counting and Matrix-Assisted Laser Desorption/Ionization (MALDI) Biotyping of representative isolates. Over all samples, colony counting ...
The parameters that were measured were total suspended solids, BOD, ammonia, nitrogen, and phosphorus. Eschricia coli (E. coli) colonies were also measured. The sludge blanket depth was measured before the aerator was turned on and again at the 60 day point. ...
After a 48-hour incubation period, colonies of bacteria were counted and compared to a control culture of Pseudomonas aeruginosa to determine their antibiotic resistance. ...
Bacterial viability on the QAC-modified membrane was confirmed via colony count method and visualized via bacterial viability assay. The QAC membrane decreased the viability of Escherichia coli to 62% and Staphylococcus aureus to 77% versus the control membrane. ...
The truth is; there is no standard method for plating high count Bacillus powders. Because there is no standard method for plating Bacillus powders, most labs will attempt to use a plate count method for plating water or wastewater. ...
An initial inoculum of 1 × 106 colony forming units (cfu)/mL was used for survival studies. Distilled water, chlorinated tap water and Mueller–Hinton broth were used as controls. Colony counts in all different waters were lower than those achieved with Mueller–Hinton broth over all incubation periods. ...
The turbidity, permanganate index, UVA254, colony counts and the concentrations of NO3−, NO2−, NH4+, Fe, Mn and Mg of the effluents from each unit of this combined system were measured to investigate the pollutant removal of this system. ...
Among these, the four predictions were very close to the average colony count. The results also showed the sensitivity of the rapid method (<104 CFUs/100 ...
Treated sewage sludge was then evaluated with different parameters, viz., Chemical Oxygen Demand(COD), Biochemical Oxygen Demand (BOD), Total Nitrogen, Total Phosphorus, Total Ammonia and Total Viable Count. Bacterial colonies were analysed after staining with Gram stain. ...
Air sampling methods can be divided into two different categories: methods generating total spore counts, typically reported as counts per cubic meter (m3) and methods that determine 'culturable fungi', typically reported as colony forming units (CFU) per cubic meter. ...
