2. Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
Abstract: Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical and cosmetic industries. The CGTases are classified according to their product specificity in α-, β-, α/β- and γ-CGTases. As

3. Concentrated beta-galactosidase and cell permeabilization from Saccharomyces fragilis IZ 275 for beta-galactosidase activity in the hydrolysis of lactose
Abstract The cheese whey shows an organic nutrient charge that can be used to obtain metabolites of interest by biotechnology of microorganisms. Thus, fermentative processes for enzyme production, in particular beta-galactosidase becomes feasible. The enzyme plays an important role in the biotech food industry to obtain milk and dairy products with low lacto

4. Evaluation of surfactant activity and emulsifying of Pea protein isolate (Pisum sativum L.) obtained by the spray dryer
ABSTRACT This study evaluates the biosurfactant activity and emulsification ability of pea proteins isolated (Pisum sativum L.). The results showed that aqueous solutions containing the pea proteins isolated (PPI) reduce the water surface tension to 47mN/m, approximately. The use of spray dryer does not change the surfactant activity of the PPI because surfa

5. Morpho-anatomical study of Stevia rebaudiana roots grown in vitro and in vivo
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, is used as a food additive because its leaves are a source of steviol glycosides. There are examples of tissue culture based on micropropagation and phytochemical production of S. rebaudiana leaves but there are few studies on adventitious root culture of S. rebaudiana. More than 90% of the plants use

6. Applications of Plackett–Burman and Central Composite Design for the Optimization of Novel Brevundimonas diminuta KT277492 Chitinase Production, Investigation of its Antifungal Activity
ABSTRACT Biological control strategy which can damage chitin, a vital component of pathogenic fungi and arthropods promises a safe solution for many fungal problems. And it’s more favorable than chemicals which increase health risks and environmental problems. Thus, the chitinase producers appear potential candidates of biological control of pathogenic fun

7. The Multiple Faces of Eugenol. A Versatile Starting Material and Building Block for Organic and Bio-Organic Synthesis and a Convenient Precursor Toward Bio-Based Fine Chemicals
Phenylpropenes are produced by plants as part of their defense strategy against microorganisms and animals, and also as floral attractants of pollinators. Eugenol, the main component of clove’s essential oil, is an inexpensive and easily available phenylpropene that has been known by humankind since antiquity, and used as a medicinal agent, but also for fo

8. A biotechnology perspective of fungal proteases
Proteases hydrolyze the peptide bonds of proteins into peptides and amino acids, being found in all living organisms, and are essential for cell growth and differentiation. Proteolytic enzymes have potential application in a wide number of industrial processes such as food, laundry detergent and pharmaceutical. Proteases from microbial sources have dominated

10. Prions: the danger of biochemical weapons
The knowledge of biotechnology increases the risk of using biochemical weapons for mass destruction. Prions are unprecedented infectious pathogens that cause a group of fatal neurodegenerative diseases by a novel mechanism. They are transmissible particles that are devoid of nucleic acid. Due to their singular characteristics, Prions emerge as potential dang

11. Identification of blood meal sources of Lutzomyia longipalpis using polymerase chain reaction-restriction fragment length polymorphism analysis of the cytochrome B gene
An analysis of the dietary content of haematophagous insects can provide important information about the transmission networks of certain zoonoses. The present study evaluated the potential of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the mitochondrial cytochrome B (cytb) gene to differentiate between vertebrat

12. Tank bromeliad water: similar or distinct environments for research of bacterial bioactives?
The Atlantic Rainforest does not have a uniform physiognomy, its relief determines different environmental conditions that define the composition of its flora and fauna. Within this ecosystem, bromeliads that form tanks with their leaves hold water reservoirs throughout the year, maintaining complex food chains, based mainly on autotrophic and heterotrophic
