On the interaction of avidin and oleic acid.

چکیده
Under appropriate conditions, oleic acid replaces biotin for several lactic acid bacteria.‘, z This growth-promoting action of oleic acid is not nullified by excess avidin for Streptococcus jaecalis R2 or for several other organisms (Table I). Egg white did, however, block utilization of oleic acid by Lactobacillus arabinosus (Table I). This result is obtained whether oleic acid is added alone, as Tween 80, or as the free acid with Tween 40. Purified samples of ovalbumin, conalbumin, and lysosyme were ineffective in preventing utilization of oleic acid. Purified avidin (3500 units per gm.) was

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...

Storage conditions of oil seeds before industrial extraction might influence the quality of the crude oil. The aim of present study was to clarify the storage able potency of high and low oleic cultivars of sunflower based on oil and fatty acid changes of seeds and their viability. The seed samples of four sunflower cultivars (two high oleic and two low oleic) were stored in three different tem...

A simple, rapid and economic procedure was presented to remove lead(II) from aqueous solution under the optimized conditions. It is based on the sorption of Pb2+ ions from aqueous solutions onto limestone fines (LS), which is an inexpensive and widespread over the globe, followed by flotation with oleic acid (HOL) surfactant. The different parameters (namely: solution pH, sorbent...
