The precise determination of the colour oils and fats is a common important parameter for production oils, fats, margarine, mayonnaise. A new method has been developed tested in order to improve reliability reproducibility results. It based on values, which describe 3D space as defined by International Commission Illumination (CIE) CIE 1976 (L*a*b*). precision data obtained from collaborative v...

An investigation of the phenotypic characteristics 19 rhizobial strains, isolated from root nodules different plant legumes grown in soil agriculture farms Ismailia governorate, transpired. Most isolates were creamy or white opaque, mucoid, with a convex elevation, translucent, and smooth margined. Microscopic revealed that all bacterial rod-shaped had no positive affinity for Gram-stain. Ident...

INTRODUCTION In this study, the clinical features, underlying diseases and clinical outcomes of patients with cryptococcosis were investigated. In addition, a molecular analysis of the Cryptococcus neoformans species complex isolated from these patients was performed. METHODS A prospective study of 62 cases of patients with cryptococcal infection was conducted at the Hospital de Doenças Tropi...

UNLABELLED BACKGROUND The Cryptococcus spp is currently composed of encapsulated yeasts of cosmopolitan distribution, including the etiological agents of cryptococcosis. The fungus are found mainly in substrates of animal and plant origin. Human infection occurs through inhalation of spores present in the environment. METHODS Eighty-four swab collections were performed on dust found on boo...

INTRODUCTION Cryptococcosis is a systemic fungal infection that affects humans and animals, mainly due to Cryptococcus neoformans and Cryptococcus gattii. Following the epidemic of acquired immunodeficiency syndrome (AIDS), fungal infections by C. neoformans have become more common among immunocompromised patients. Cryptococcus gattii has primarily been isolated as a primary pathogen in healthy...

The key to obtaining an optimum performance of an enzyme is often a question of devising a suitable enzyme and optimisation of conditions for its immobilization. In this study, laccases from the native isolates of white rot fungi Fomes fomentarius and/or Trametes versicolor, obtained from Czech forests, were used. From these, cross-linked enzyme aggregates (CLEA) were prepared and characterised...

L-Asparaginase is a chemotherapeutic drug used in the treatment of acute lymphoblastic leukaemia (ALL), a malignant disorder in children. L-Asparaginase helps in removing acrylamide found in fried and baked foods that is carcinogenic in nature. L-Asparaginase is present in plants, animals and microbes. Various microorganisms such as bacteria, yeast and fungi are generally used for the productio...

1. Fatty n-acyl-CoA derivatives in the concentration range 5muM-0.1mM and with 5-18 fatty acyl carbons have dual effects on phosphate-activated glutaminase from pig brain and kidney. Generally, fatty acyl-CoA derivatives in low concentrations activate the enzyme, but inhibit at higher concentrations; phosphate and citrate potentiate the activation, displaying positive co-operatively, and protec...

BACKGROUND Hexuronic acids such as D-galacturonic acid and D-glucuronic acid can be utilized via different pathways within the metabolism of microorganisms. One representative, the oxidative pathway, generates α-keto-glutarate as the direct link entering towards the citric acid cycle. The penultimate enzyme, keto-deoxy glucarate dehydratase/decarboxylase, catalyses the dehydration and decarboxy...
