01:24Techniques for Isolation of Pure Cultures
Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...
01:24iChip
The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...
