The Isolation chip (or ichip) is a method of culturing bacteria. Using regular methods, 99% of bacterial species are not able to be cultured as they do not grow in conditions made in a laboratory, a problem called the "Great Plate Count Anomaly". [1] The ichip instead cultures bacterial species within its soil environment.
Off-chip HPLC columns are used to separate analytes before feeding them into a microfluidic device for fractionation and analysis. [214] HPLC columns can also be built directly into microfluidic lab-chips creating monolithic hybrid devices capable of chemical separation as well as droplet formation and manipulation.
Some types of bacteria can only grow in the presence of certain additives. This can also be used when creating engineered strains of bacteria that contain an antibiotic-resistance gene. When the selected antibiotic is added to the agar, only bacterial cells containing the gene insert conferring resistance will be able to grow.
Bacteria, which can thrive in places where humans wouldn't dare linger, can be friends or foes. Take E. coli. Some strains are harmless and settle comfortably in animals' lower intestines. Others ...
Gram-negative bacteria will stain a pink color due to the thin layer of peptidoglycan. If a bacteria stains purple, due to the thick layer of peptidoglycan, the bacteria is a gram-positive bacteria. [4] In clinical microbiology numerous other staining techniques for particular organisms are used (acid fast bacterial stain for mycobacteria).
Science Journal for Kids is an online scientific journal that publishes adaptations designed for children and teens of academic research papers that were originally published in high-impact peer-reviewed journals, as well as science teaching resources for teachers.
TSA plates support growth of many semifastidious bacteria, including some species of Brucella, Corynebacterium, Listeria, Neisseria, and Vibrio. Xylose-lysine-deoxycholate agar is used for the culture of stool samples and contains two indicators. It is formulated to inhibit Gram-positive bacteria, while the growth of Gram-negative bacilli is ...
