1. The genotypic diversity and lipase production of some thermophilic bacilli from different genera
Abstract Thermophilic 32 isolates and 20 reference bacilli were subjected to Rep-PCR and ITS-PCR fingerprinting for determination of their genotypic diversity, before screening lipase activities. By these methods, all the isolates and references could easily be differentiated up to subspecies level from each other. In screening assay, 11 isolates and 7 refer

2. Isolamento, seleção e cultivo de bactérias Produtoras de lipases para tratamento de Efluentes da indústria de alimentos / Isolation, selection and cultivation of bacteria Producing lipases for treating Effluents of the food industry
The present work was to isolate, select and cultivate microorganisms that produce lipases to apply the wastewater treatment industry of potato chips. For the isolation of microorganisms was used for industrial effluent and sewage treatment plant. The selection of the strain producing lipase was performed on solid medium containing tributyrin and in liquid me

4. Chemopreventive activity of tributyrin in hepatocarcinogenesis in rats / Atividade quimiopreventiva da tributirina na hepatocarcinogênese em ratos
No presente estudo avaliou-se a atividade quimiopreventiva da tributirina (T), pró-fármaco do ácido butírico (AB) e presente naturalmente em leite e derivados, quando administrada a ratos Wistar durante as etapas de iniciação e seleção/promoção do modelo de hepatocarcinogênese do "Hepatócito Resistente" (RH). Os animais receberam diariamente, dur

5. Quantitative spectrophotometric assay for staphylococcal lipase.
We report the development of a specific spectrophotometric assay for the quantitative determination of lipase activity in Staphylococcus aureus. The assay is based on the rate of clearance of a tributyrin emulsion, and it can detect as little as 1.0 micrograms of purified Pseudomonas lipase per ml. By comparison with the reaction rates obtained with Pseudomo

6. Ruminal Bacterial Degradation of Benzo(b)-thien-4-yl Methylcarbamate (Mobam) and Effect of Mobam on Ruminal Bacteria
Mixtures of ruminal bacteria degraded benzo(b)thien-4-yl methylcarbamate (Mobam) to 4-hydroxybenzothiophene, CO2, and polar product(s). The metabolite, 4-hydroxybenzothiophene, was identified (after acetylation) by comparative infrared and mass spectrometry with an authentic sample. Carbon dioxide and polar product(s) were produced by degradation of the meth

7. Lipid Metabolism of Rumen Ciliates and Bacteria: II. Uptake of Fatty Acids and Lipid Analysis of Isotrichia intestinalis and Rumen Bacteria with Further Information on Entodinium simplex
The total lipid and free fatty acid contents of Isotricha intestinalis, Entodinium simplex, and the rumen bacterial flora of the respective protozoa were determined. Warburg manometric data showed that the sodium salts of tributyrin, oleic, and acetic acids stimulated gas production in I. intestinalis, whereas tributyrin was stimulatory with E. simplex and l

8. Further Evidence for Selective Differences between Isoalleles in Drosophila
A number of separate strains of Drosophila pseudoobscura were inbred for 38 generations of brother-sister mating with forced heterozygosity for two alleles of either the octanol dehydrogenase or esterase-5 locus. Crosses were set up within each of these inbred lines such that simple mendelian ratios were expected, and eggs from these crosses were placed on m

10. Cell-Bound Lipase and Esterase of Brevibacterium linens
The activities of glycerol ester hydrolase, lipase (EC 3.1.1.3) and carboxylesterase, and esterase (EC 3.1.1.1) were determined for whole cell preparations of Brevibacterium linens by using the pH-stat assay. The culture growth liquors were inactive against the three substrates, tributyrin emulsion, triacetin, and methyl butyrate. Cells washed in water had l

11. Purification and Properties of a Glycerol Ester Hydrolase (Lipase) from Propionibacterium shermanii
An intracellular glycerol ester hydrolase (lipase) from Propionibacterium shermanii was recovered from cell-free extracts and purified by ammonium sulfate precipitation, gel filtration, and ion-exchange chromatography on diethylaminoethylcellulose. Maximum enzyme activity was observed at pH 7.2 and 47 C when an emulsion of tributyrin was used as substrate. T

12. CHARACTERIZATION OF LEPTOSPIRAL LIPASE
Patel, Virendra (University of Missouri, Columbia), Herbert S. Goldberg, and Donald Blenden. Characterization of leptospiral lipase. J. Bacteriol. 88:877–884. 1964.—A technique for leptospiral lipase extraction which yielded a highly active, stable, and concentrated lipase preparation was developed. The chief characteristics of leptospiral lipase were de
