Liquid-grown Streptomyces cultures are characterized by mycelial pellets that are heterogeneous in size. We here describe a method to analyze and sort such pellets in a high-throughput manner. These pellets can be used for further analyses, which will provide leads to understand and control growth heterogeneity.

In this study, a protocol was developed to produce good quality pellets using a flat die pellet mill at reduced specific energy consumption testing high-moisture corn stover and a starch based binder. The results indicated that adding a corn starch binder improved the pellet durability, reduced percent fines and decreased specific energy consumption.
FAQs
During centrifugation, rapid spinning generates a force that drives suspended cells toward the tube bottom. As cells collect, they form a compact pellet, while the surrounding liquid remains above as the supernatant. This separation creates two physically distinct fractions, allowing investigators to retain the cells, the liquid, or both for subsequent biological analysis.
The pellet is an intermediate sample that can be manipulated for different goals. Removing the supernatant concentrates the cells, whereas resuspending returns them to a liquid state. Washing can help prepare the collected cells, and lysis can prepare them for downstream molecular or protein analysis. Preservation provides another option when immediate experimentation is not planned.
These treatments adapt the collected material to the next stage of an experiment. Resuspension places the cells back into a liquid, washing prepares the pellet for further handling, lysis supports analysis of cellular material, and preservation maintains the sample for later use. The appropriate choice depends on whether the study requires intact cells, processed material, or stored samples.
A basic workflow begins with a cell suspension in a tube and centrifugation to separate its contents. After spinning, the supernatant is removed carefully, leaving the pellet available for resuspension, washing, lysis, or preservation. The selected downstream step should match the intended analysis because each treatment determines how the collected cells can be used.
The essential setup consists of a liquid cell suspension, a tube, and a centrifuge capable of rapid spinning. The tube holds the two resulting fractions, while the centrifuge supplies the force needed to collect cells at the bottom. After separation, additional handling materials may be selected according to whether the cells will be counted, observed, analyzed, maintained, or preserved.
Researchers use this preparation before cell counting and microscopy when cells need to be concentrated into a sample that can be handled for observation. Once collected, the pellet can be resuspended or otherwise prepared for analysis. This approach supports examination of cells that would otherwise remain dispersed throughout the original liquid suspension.
In molecular biology and protein analysis, the collected pellet can be resuspended, washed, or lysed before further experimentation. These options make the same initial separation compatible with different downstream workflows, from handling intact cells to processing cellular material. The method also supports culture maintenance by providing a concentrated cell sample that can be handled again.
