Aseptic packaging are generally placed in the following categories: [9] fill, erect, form, thermoform, blow mold, and bulk packaging and storage systems. [3] Fill and seal. The containers are filled and sealed in a sterile environment to avoid contamination. Erect, fill and seal. A plastic container is erected then sterilized, filled and sealed.
After the required incubation period, when an even lawn of growth is distinctly visible, the MIC value is read where the pointed end of the inhibition ellipse intersects the side of the strip. Etests can be used as an alternative method to determine the minimum inhibitory concentrations of a wide range of antimicrobial agents against different ...
A bag-in-box or BiB is a container for the storage and transportation of liquids. [1] It consists of a strong bladder (or plastic bag), usually made of several layers of metallised film or other plastics, seated inside a corrugated fiberboard box. [1] The BiB is used because of its easy transportation and ability to dispense liquids.
A plastic strip impregnated with different concentrations of antibiotics is placed on a growth medium, and the growth medium is viewed after a period of incubation. [5] The minimum inhibitory concentration can be identified based on the intersection of the teardrop-shaped zone of inhibition with the marking on the strip. [ 5 ]
Wherever food is harvested, manufactured or distributed there is a need for containers to enable the food to travel securely and in good condition to the shop, warehouse or distribution depot. For many foods, especially those in their own individual containers such as canned vegetables, the common container is the corrugated fiberboard box ...
The dip slide test consists of a sterile culture medium on a plastic carrier that is dipped into the liquid to be sampled. [3] The culture is then incubated, allowing for microbial growth. [2] Most Dip slides consist of 1 - 2 agars attached to a flexible plastic paddle, this allows full contact of the agar onto the desired area for testing. [4]
The broth microdilution method can be used to test the susceptibility of microorganisms to multiple antibiotics at once. [4] Broth microdilution is also highly accurate. The accuracy of its results are comparable to agar dilution, the gold standard of susceptibility testing. Other advantages include the commercial availability of plates, the ...
A more recent concern in microplastic pollution is the use of plastic films in agriculture. 7.4 million tons of plastic film are used each year to increase food production. [22] Scientists have found that microbial biofilms can form within 7–14 days on plastic film surfaces, and have the ability to alter the chemical properties of the soil ...
