Analysis of fatty acid composition in liquid culture media after lipophilic bacterial strains cultivation was carried out. Pure cultures were earlierisolated from fat-containing wastes and cultivated on media with diverse fat sources. It was shown that microorganisms hydrolyze animal and milk fats to free fatty acids.

1. The specimen of sea-urchin semen examined contained 0.95% lipid material consisting of 13.6% neutral fat, 32.9% free fatty acids, 26.0% phospholipids, 9.2% sterols and 18.3% other unsaponifiable material. 2. The component fatty acids of the non-phosphorus-containing lipids have been computed to be: palmitic 10.1, unsaturated C16 2.1 (-3.0), C18 30.4 (-4.9), C20 45.1 (-7.0), C22 12.3 (-6.5)%, w/w, this being a composition which can be regarded as typical of a marine animal fat. 3. The N : P ratio of the phospholipids indicated the presence of mono- and diaminophosphatides and possibly the presence of non-phosphorus-containing lipoproteins. 4. Adequate reserves of non-phosphorus-containing lipids are present in the spermatozoa, in addition to phospholipids to serve as a source of energy required for movement.

Biodiesel Purification

AbstractSeveral techniques, in which different homogenous catalysts and procedures, that are in use for transesterification of a vegetable oil or an animal fat have been successful in synthesizing biodiesel, although with some certain limitations. For such a purpose, among the catalysts employed are acidic as well as basic catalysts. It has been found that acidic catalysts can be tolerant with a high content of free fatty acids found in those low value feedstock oils/fats to be transesterified, although some sort of pretreatment by means of esterification might be required in order to synthesize biodiesel. Moreover, with employing homogenous acidic catalysts, it seems that biodiesel purification procedures are simplified; thus, reducing synthesis cost. In fact, these features of homogenous acidic catalysts render them advantageous over basic ones. With basic homogenous catalysts this; however, has not been possible due to the development of saponification reaction. To effectively perform, such catalysts require that the content of free fatty acids in the feedstock oil/fat is minimal. This requirement is also applicable to the moisture level in the feedstock. In terms of corrosive effects; nevertheless, acidic catalysts are disadvantageous compared to basic ones.

Blood Aqueous Barrier

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.
