Salmonella typhimurium and enteritidis: bacteria were suspended in 1/
300 volume of original culture, sonified for 4 minutes and centrifuged for 20 min-
utes at 20,000 9. Extracts were found to catalyze the synthesis of cytidine diphos-
phate 3, 6-dideozyhexoses.
Schistosoma mansoni: complete disruption.
Sedimentary rock: completely disperses flocs with the release of all bound
silt and clay particles.
Sediments: ultrasonic treatment disperses fine material permitting quick, neat
separation of sand from silt and clay fractions.
Serial number restoration: used in crime laboratories to restore obliterated
serial numbers.
Serratia marcescens: complete breakdown of a concentrated solution in 1
minute.
Serum: quickly homogenized.
Serum cholinesterase: activated by ultrasonic treatment. Different cholinest-
erase isoenzymes may be activated selectively and inactivated selectively.
Shale: excellent disaggregation of all fine-grained sedimentary rocks.
Shellfish: by drilling a clean hole with the micro tip, various fluids or samples
may be withdrawn or injected from living shellfish without destroying the ani-
mals.
Shigella: quick disruption.
Skin: 1 gm disintegrates in about 4 minutes. Epidermal homogenates that
respire and utilize substrate can be extracted.
Soil: separates solid particles without use of oxidants, acids or peptizing agents
and yields stable suspensions.
Sperm (human): tails are broken instantly. Heads are broken in 20 minutes.
Sputum: cancer cells are more easily detected after ultrasonic treatment due to
even dispersion of cells and sputum, and complete liberation of the cells from spu-
tum.
Staphylococcus: a concentrated solution disrupts 98% in 10 minutes. With 1
gm cells wet wt, to 2 gm water, 54.5 mg/ml of protein was released.
Starch: obtained by extracting from green plant leaf homogenate.
Streptococcus, Group A: a 20% suspension in a 15 ml solution completely
disrupts in 15 minutes.
