What's the difference between opalescence and turbidity?

Opalescence


Definition:

  • (n.) A reflection of a milky or pearly light from the interior of a mineral, as in the moonstone; the state or quality of being opalescent.

  • (17) Adjacent filaments in the bundles had a distance of approximately 180 A. Hyper-opalescence occurred at r approximately equal to 1 when KCOOCH3 was used instead of KCl.
  • (18) Impairment of catalytic efficiency can only be documented in opalescent test solutions in which the insecticides are present in excess of their solubility limit.
  • (19) We have found that after the initial rise in scattering, there is a further gradual increase in scattering (we call it "super-opalescence").
  • (20) A fraction possibly corresponding to VHDL (very high density lipoproteins, 77% protein, 23% lipid) was also detected but appeared contaminated by a protein-rich opalescent material.

Turbidity


Definition:

  • (n.) Turbidness.

Example Sentences:

  • (1) There were found out one-sided relations for instance concerning the proportion of transaminases, thymol turbidity test as well as creatinine to the erythrocyte sedimentation rate.
  • (2) This paper describes the properties and use of a fiber optic probe as an attachment to a spectrophotometer and its use for measurements in solutions and turbid suspensions.
  • (3) Depriving the mutant of glucosamine resulted in a rapid loss of viability of the cells, followed by a decrease in the turbidity of the culture.
  • (4) This test is a rapid, inexpensive alternative to current 48- to 72-h methods in which broth turbidity is used as the end point.

  • (6) Continuous measurements were made of the turbidity of growing cultures of Escherichia coli, Streptococcus mutans, and Saccharomyces cerevisiae.
  • (7) However, the effects of temperature on the rate of assembly above 37 degrees C were opposite to the effects seen at temperatures below 37 degrees C. In the range of 37-41 degrees C, the turbidity propagation rate decreased markedly with temperature.
  • (8) In addition, control myosin synthetic thick filament length as well as turbidity in solution, measured by light scattering, were twice as large as those of the myopathic heart myosin.
  • (9) The turbidities are remarkably high when one considers the low concentrations of protein and nucleic acid materials that are used.
  • (10) It is therefore essential to take into consideration the pH and turbidity of the water before applying molluscicidal treatment.
  • (11) With increasing hydrostatic pressure, the turbidity of an alpha-crystallin solution increases exponentially to a plateau at about 6000-8000 psi; upon release of pressure, the samples slowly return to their original turbidity level.
  • (12) Turbidity curves, measured following addition of thrombin to purified fibrinogen Milano IV, both in presence of calcium or EDTA, were markedly delayed.
  • (13) The liposomal solubilization, which was monitored by turbidity measurements or by determination of phospholipid sedimentability, was accompanied by the formation of a phospholipid-protein complex similar or identical to the one we previously reported to be formed from sonicated liposomes of egg phosphatidylcholine (Scherphof, G., Roerdink, F., Waite, M. and Parks, J.
  • (14) The decrease in turbidity at 400 nm, resulting from the uptake of the micro-organisms by the neutrophils, was measured for 20-30 min and the area under the curves was taken as a measure of the opsonizing capacity of the serum or the phagocytic capacity of the neutrophils.
  • (15) After removal of the methyl ester on the side chain of Glu, these polymers exhibited a remarkable pH dependence of the temperature for their inverse temperature transitions, which are followed as turbidity development at 300 nm.
