1. Optimization of RT-PCR reactions in studies with genes of lignin biosynthetic route in Saccharum spontaneum
ABSTRACT Saccharum spontaneum has been used for the development of energy cane a crop aimed to be used for the production of second-generation ethanol, or lignocellulosic ethanol. Lignin is a main challenge in the conversion of cell wall sugars into ethanol. In our studies to isolate the genes the lignin biosynthesis in S. spontaneum we have had great diffic

2. Management of freezing rate and trehalose concentration to improve frozen dough properties and bread quality
Abstract Bread is one of the most consumed foods in the world, and alternatives have been sought to extend its shell life, and freezing is one of the most popular methods. The purpose of this study was to evaluate the effect of freezing rate and trehalose concentration on the fermentative and viscoelastic properties of dough and bread quality. Dough was prep

3. Bioaccumulation of aluminium and its effects on toxic alcoholic fermentation in industries strains of Saccharomyces cerevisiae / Bioacúmulo de alumínio e seus efeitos tóxicos na fermentação alcoólica em linhagens industriais de Saccharomyces cerevisiae
This study aimed to assess the effect of aluminium on the alcoholic fermentation using different strains of industrial yeasts (CAT-1, BG-1, PE-2, Fleischmann and wild yeast colonies isolated from production of alcohol fuel called C1, C5 , C6, C8, C10 and C11) in different concentrations of aluminium and also examine the accumulation of metal in yeast during

4. Seleção de leveduras produtoras de trealose e otimização da produção utilizando estrategias sequenciais de planejamento experimental / Screening for trehalose producing yeasts and optimization of production following a sequential strategy of experimental design
Trehalose is a natural cell-protecting agent that has been isolated and characterized from a large variety of plants, insects, fungi and bacteria, and many studies indicate that this disaccharide is an essential component for maintaining cell viability under stress conditions. Due to the potential application of trehalose, especially in cosmetics and pharmac

5. Dipropionato de beclometasona em formulação lipossomal como po inalavel para o tratamento de doenças pulmonares
The liposomal drug encapsulation for medical applications is in many instances the most efficient way to ensure good storage, transport, targeting, and controlled release of the drug, thus reducing toxicity. Liposomes have been extensively studied as vehicles for efficient drug delivery. The objective of the present work is to develop a formulation of the co

6. Papel da trealose no metabolismo de larvas de Pyrearinus termitilluminas (coleoptera: elateridae) sob estresse hídrico / The role o trehalose in the metabolism of Pyresrinus termitilluminas larvae (coleoptera: elateridae) under hidric stress
The life cycle of Pyrearinus termitilluminans (Coleoptera: Elateridae) takes place totally into the so-called luminous termite mounds located in Central Brazil, which are clearly observed during the rainy season. Light emission by the elaterid larvae acts like a trap attracting flying insects. The bioluminescence disappears in the dry months together with th

7. Caracterização de leveduras de processos de fermentação alcoolica utilizando atributos de composição celular e caracteristicas cineticas
In the past years, there has been a significant increase in studies seeking to understand the dynamics of the yeast population inhabiting alcoholic fermentation vats. The studies generated have elucidated important issues. Among them, which would be the basic characteristics for a strain to remain in a processo Following this context, this study has had the

8. Expression of a Bifunctional Fusion of the Escherichia coli Genes for Trehalose-6-Phosphate Synthase and Trehalose-6-Phosphate Phosphatase in Transgenic Rice Plants Increases Trehalose Accumulation and Abiotic Stress Tolerance without Stunting Growth1
Trehalose plays an important role in stress tolerance in plants. Trehalose-producing, transgenic rice (Oryza sativa) plants were generated by the introduction of a gene encoding a bifunctional fusion (TPSP) of the trehalose-6-phosphate (T-6-P) synthase (TPS) and T-6-P phosphatase (TPP) of Escherichia coli, under the control of the maize (Zea mays) ubiquitin

9. Overproduction of Trehalose: Heterologous Expression of Escherichia coli Trehalose-6-Phosphate Synthase and Trehalose-6-Phosphate Phosphatase in Corynebacterium glutamicum
Trehalose is a disaccharide with potential applications in the biotechnology and food industries. We propose a method for industrial production of trehalose, based on improved strains of Corynebacterium glutamicum. This paper describes the heterologous expression of Escherichia coli trehalose-synthesizing enzymes trehalose-6-phosphate synthase (OtsA) and tre

10. Trehalose Synthesis by Sequential Reactions of Recombinant Maltooligosyltrehalose Synthase and Maltooligosyltrehalose Trehalohydrolase from Brevibacterium helvolum
A DNA fragment encoding two enzymes leading to trehalose biosynthesis, maltooligosyltrehalose synthase (BvMTS) and maltooligosyltrehalose trehalohydrolase (BvMTH), was cloned from the nonpathogenic bacterium Brevibacterium helvolum. The open reading frames for the two proteins are 2,331 and 1,770 bp long, respectively, and overlap by four nucleotides. Recomb

11. Sequential Primary and Secondary Shunt Metabolism in Penicillium chrysogenum1
Penicillium chrysogenum was grown on a rich medium and on a more sparse medium which favored penicillin production. Mycelia grown on both media were examined for changes in lipid, mannitol, erythritol, glycerol, pentitol, trehalose, and residual mycelium, and the filtrates were examined for penicillin. Penicillin production took place after the bulk of treha

12. Impact of Heterologous Expression of Escherichia coli UDP-Glucose Pyrophosphorylase on Trehalose and Glycogen Synthesis in Corynebacterium glutamicum
Trehalose is a disaccharide with a wide range of applications in the food industry. We recently proposed a strategy for trehalose production based on improved strains of the gram-positive bacterium Corynebacterium glutamicum. This microorganism synthesizes trehalose through two major pathways, OtsBA and TreYZ, by using UDP-glucose and ADP-glucose, respective
