Purification and Characterization of the alpha-Glucosidase Produced by Thermophilic Fungus Thermoascus aurantiacus CBMAI 756
(Journal of Microbiology, 2010-08-01) [Artigo]
An alpha-glucosidase enzyme produced by the fungus Thermoascus aurantiacus CBMAI 756 was purified by ultra filtration, ammonium sulphate precipitation, and chromatography using Q Sepharose, Sephacryl S-200, and Superose ...
Production and characterization of a milk-clotting protease in the crude enzymatic extract from the newly isolated Thermomucor indicae-seudaticae N31 (Milk-clotting protease from the newly isolated Thermomucor indicae-seudaticae N31)
(Food Chemistry, 2010-05-01) [Artigo]
Microbial rennet-like milk-clotting enzymes are aspartic proteinases that catalyze milk coagulation. substituting calf rennet. Crude enzymatic extract produced by the thermophilic fungus, Thermomucor indicae-seudaticae ...
Chromosomal location of heterochromatin and 45S rDNA sites in four South American triatomines (Heteroptera: Reduviidae)
(Comparative Cytogenetics, 2010-01-01) [Artigo]
The Triatominae are distributed in Brazilian regions and are the vector of Chagas disease. This group is also characterized by lower karyotype variability, occurrence of holokinetic chromosomes and inverted meiosis of the ...
Detection of numerical chromosome anomalies in interphase cells of benign and malignant thyroid lesions using fluorescence in situ hybridization
(Cancer Genetics and Cytogenetics, 2000-02-01) [Artigo]
Benign and malignant thyroid tumors constitute a wide range of neoplasias showing recurrent chromosome abnormalities. In an attempt to characterize specific numerical chromosome abnormalities in thyroid tissues, We present ...
The development of resistance to caffeine in Drosophila prosaltans: productivity and longevity after ten generations of treatment
(Cytobios, 1998-01-01) [Artigo]
The productivity of Drosophila prosaltans treated with six concentrations of caffeine (from 50 mu g/ml to 2,500 mu g/ml of culture medium) during ten generations (similar to 8 months) decreased in a dosage dependent manner ...
Screening of bacterial strains for pectinolytic activity: characterization of the polygalacturonase produced by Bacillus sp
(Revista de Microbiologia, 1999-12-01) [Artigo]
A partir de amostras de solo e de material vegetal em decomposição, foram isoladas 168 linhagens bacterianas capazes de utilizar pectina de citrus como única fonte de carbono. Destas, 102 foram positivas para a despolimerização ...
Nucleolar behaviour during meiosis in four species of phyllostomid bats (Chiroptera, Mammalia)
(Genetics and Molecular Research, 2011-01-01) [Artigo]
We analyzed the behavior of the nucleolus, nucleolar structures and nucleolus organizer regions (NORs) during meiotic division in four species of phyllostomid bats that have different numbers and locations of NORs. Nucleoli ...
Alternative method of smearing samples on slides facilitate visualization of hemoglobin H inclusion bodies in alpha thalassemia
(Revista Brasileira de Hematologia e Hemoterapia, 2008-02-01) [Artigo]
Nas talassemias alfa, a HbH pode ser detectada, nos eritrócitos do sangue periférico como inclusões celulares quando coradas com azul crezil brillante. Este teste simples é útil para o diagnóstico de talassemia alfa, no ...
