1. Rua de mão única: uma leitura do romance Passado Contínuo de Yakov Shabtai / One hand street: space study in Yaakov Shabtai\ s Past Continuous
Yaakov Shabtai (1934-1981), wrote Past Continuous, his first novel, almost thirty years after the foundationof Israel, out of third war in 30 years of its rise. The novel exposes the lives of three men, their relationships and families, their projects and frustrations, showing numerous other characters who flock and disappear over the storyline. His scenario

2. Chromosome 20 long arm deletion in an elderly malformed man.
A 46,XY/46,XY,del(20)(q13-->q13.33) mosaicism was identified in a 68 year old man who had mild mental retardation and severe malformation of the limbs. The clinical findings of the patient are compared to those of the very few cases of 20q deletion published to date.

3. Enhanced emulsan production in mutants of Acinetobacter calcoaceticus RAG-1 selected for resistance to cetyltrimethylammonium bromide.
Mutants of Acinetobacter calcoaceticus RAG-1 that produced elevated levels of the polymeric bioemulsifier emulsan were isolated on the basis of their resistance to the cationic surfactant cetyltrimethylammonium bromide (CTAB). Such mutants showed maximum enhancement in both overall yield and specific productivity of some two- to threefold over that of the wi

4. Tolerance of Acinetobacter calcoaceticus RAG-1 to the cationic surfactant cetyltrimethylammonium bromide: role of the bioemulsifier emulsan.
Emulsan, the polyanionic heteropolysaccharide bioemulsifier produced by Acinetobacter calcoaceticus RAG-1, was found to enhance the tolerance of RAG-1 cells to the toxic effects of the cationic detergent cetyltrimethylammonium bromide (CTAB). Emulsan-mediated tolerance was obtained with the purified deproteinated apoemulsan; ca. 9 micrograms of apoemulsan ne

5. Exocellular esterase and emulsan release from the cell surface of Acinetobacter calcoaceticus.
An esterase activity has been found, both in the cell-free growth medium and on the cell surface of the hydrocarbon-degrading Acinetobacter calcoaceticus RAG-1. The enzyme catalyzed the hydrolysis of acetyl and other acyl groups from triglycerides and aryl and alkyl esters. Emulsan, the extracellular heteropolysaccharide bioemulsifier produced by strain RAG-

6. Isolation and characterization of a lipolytic bacterium capable of growing in a low-water-content oil-water emulsion.
A unique lipolytic bacterium was isolated in a selective growth system consisting of 99% triglycerides and a 1% water phase. The bacterium, termed Pseudomonas aeruginosa YS-7, was able to grow in an environment of low water content and could also survive amphipathic, osmotic, and matrical water stress in a triglyceride-rich culture. The isolated strain was i

7. Production, purification, and properties of a lipase from a bacterium (Pseudomonas aeruginosa YS-7) capable of growing in water-restricted environments.
An extracellular lipase from the low-water-tolerant bacterium P. aeruginosa YS-7 was produced, purified, and characterized with respect to its functional properties in aqueous solutions and organic solvents. The enzyme was partially released from the cells during fermentation in defined medium with 5% (wt/vol) soybean oil. Approximately one-half of the total

8. Adsorption of Rhodococcus Strain GIN-1 (NCIMB 40340) on Titanium Dioxide and Coal Fly Ash Particles
Rhodococcus strain GIN-1 (NCIMB 40340) can be used to enrich and isolate a titanium-rich fraction from coal fly ash. The gram-positive bacterium was isolated by its ability to adhere strongly and rapidly to suspended particles of pure titanium dioxide or coal fly ash. Adsorption depends on the salt concentration and occurs in seawater. Lowering of the salt c
