| Term | Definition |
|---|---|
| Saprobe |
An organism that derives its primary nutrition from decaying carbonaceous matter.
|
| Scanning Electron Microscopy (SEM) |
Magnification 450-15,000x. Analytical technique used for air and bulk sample analysis. May use Energy Dispersive Spectroscopy (EDS) to positively identify chemical elements present in the sample. Method involves counting fibers (discriminating between fibers less than and greater than 5.0 microns length) in a known surface area of a filter or bulk material.

| Sclerotium |
Tightly bound mass of hyphae. Usually resistant to disruption.
|
| Selective Media |
Medium that encourages selective growth of an organism while attempting to prevent others from growing with it.
|
| Sepsis |
The introduction or presence of disease causing organisms (usually microbial) into the blood or bodily fluids.

|
| Spore Trap (Non |
Culturable)
|
| Sterile (Hyphae) |
Hyphae lacking or ceasing to produce spores.
|
| STLC |
Soluble Threshold Limit Concentration used in the State of California in conjunction with TTLC to determine lead hazardous waste limits. If the STLC result is equal to or exceeds 5 mg/L the waste is deemed to be hazardous.
|
| Surfactant |
A chemical wetting agent added to water.
|
| Swab Sample |
A technique for collecting microbial specimens using a sterile swab of cotton that can be sealed and either analyzed directly or following culture.
