1. Pentoses Used in Cultures of Synechococcus nidulans and Spirulina paracas: Evaluation of Effects in Growth and in Content of Proteins and Carbohydrates
Abstract The biological assimilation of the sugars present in lignocellulosic residues has gained prominence since these residues are the most abundant and economic residues in nature. Thus, the objective of this work was to determine whether the use of D-xylose and L-arabinose as sources of carbon in Synechococcus nidulans and Spirulina paracas cultures af

3. Modelagem e simulação do crescimento de Talaromyces flavus em abacaxi: uma integração entre modelos cinéticos e de fenômenos de transporte
Resumo O estudo da dinâmica de crescimento de microrganismos em alimentos é de vital importância para a extensão da vida de prateleira desses produtos. No presente trabalho, um modelo de cinética microbiológica descrevendo o crescimento de Talaromyces flavus em abacaxi foi integrado com um modelo térmico. O modelo integrado foi utilizado para simular

4. INDUSTRIAL PLANT FOR PRODUCTION OF Spirulina sp. LEB 18
ABSTRACT Biorefineries based on microalgae produce biofuels and co-products with added value. Microalgae mainly require water, carbon dioxide and sunlight for growth. The bioproducts of the cultivation of these microorganisms can be fully used in a microalgae photobiorefinery. The objective of this work was to study the behavior of physico-chemical variables

5. Understanding the Surfaces and Crystal Growth of Pyrite FeS2
Pyrite is a common sulfide mineral, which has arisen early interest by its euhedral shape and by its metallic glow similar to gold. However, it is only in our century that we began to understand pyrite crystal growth, considering the thermodynamic and kinetic aspects of crystal formation as a function of temperature and concentration of the elements present

6. Contribution of dark septate fungi to the nutrient uptake and growth of rice plants
ABSTRACT The use of dark septate fungi (DSE) to promote plant growth can be beneficial to agriculture, and these organisms are important allies in the search for sustainable agriculture practices. This study investigates the contribution of dark septate fungi to the absorption of nutrients by rice plants and their ensuing growth. Four dark septate fungi isol

7. AnaBioPlus: a new package for parameter estimation and simulation of bioprocesses
Abstract A very important step in the study of bioprocesses is the modeling and simulation of bioreactors. This paper presents the AnaBioPlus software package, which was developed for teaching and research purposes concerning the analysis of bioreactors. The package consists of two programs: OptimusFerm and SimulaFerm. OptimusFerm allows the analysis of expe

8. The Role that Electrolytes Play in the Synthesis of Water-Soluble CdTe Quantum Dots Prepared at Ambient Temperature
In this work, we have synthesized CdTe quantum dots (QDs) dispersed in an aqueous medium at ambient temperature, and investigated their optical properties. Synthesis of CdTe QDs in the presence of simple amines removed the need for an additional energy source and inert atmosphere, in a simple and inexpensive experimental setup. The use of ammonia or hydrazin

9. Isolation and characterization of a high salt-tolerant and glyphosate-degrading strain of Agrobacterium tumefaciens BZ8
ABSTRACT In this study, a high salt-tolerant and glyphosate-degrading strain named BZ8 was isolated from activated sludge. According to 16S rDNA sequencing methods, morphological, physiological and biochemical analysis, strain BZ8 was identified as Agrobacterium tumefaciens. The growth and glyphosate-degrading capability of A. tumefaciens BZ8 were investigat

10. Growth kinetic models of five species of Lactobacilli and lactose consumption in batch submerged culture
Abstract Kinetic behaviors of five Lactobacillus strains were investigated with Contois and Exponential models. Awareness of kinetic behavior of microorganisms is essential for their industrial process design and scale up. The consistency of experimental data was evaluated using Excel software. L. bulgaricus was introduced as the most efficient strain with t

11. BIODEGRADATION OF ACRYLIC PAINTS: PROCESS MODELLING OF BIOCIDE EFFECT ON BIOMASS GROWTH AT DIFFERENT TEMPERATURES
Abstract Acrylic paint, notwithstanding the attention paid during the production process, couldbe contaminated by bacteria. This is a consequence of microbiological residuals on the can, resulting in the alterationof paint characteristics. It is therefore necessary to provide an in-canpreservation of the paint by using a biocide.In this paper, the evolution

12. BIODEGRADATION OF PHENOL BY FREE AND IMMOBILIZED CELLS OF A NOVEL Pseudomonas sp. NBM11
Abstract In the present study, a pure culture of bacterium (Pseudomonas sp. Strain NBM11) was isolated from the soil sample from a site contaminated with medical wastes and wastewater. The isolated strain can degrade up to 1000 mg/L of phenol completely. It was observed that temperature, pH and initial concentration of phenol play key roles in determining th
