1. Antifungal and Photocatalytic Activity of Smart Paint Containing Porous Microspheres of TiO2
In this study, porous microspheres of TiO2 (µTiO2) were synthesized, characterized and incorporated into an acrylic paint formulation to obtain a photocatalytically active paint. In a novel approach, the antifungal properties of the µTiO2 paint were evaluated using Monascus ruber as the representative microorganism and compared to those of a photocatalyst-

2. CAROTENOID-PRODUCING YEASTS IN THE BRAZILIAN BIODIVERSITY: ISOLATION, IDENTIFICATION AND CULTIVATION IN AGROINDUSTRIAL WASTE
ABSTRACT Different yeast strains from forests located in southern Brazil, with potential to produce carotenoids, were isolated. Three microorganisms were selected as potential carotenoid producers. Sporiodiobolus pararoseus, Rhodotorula mucilaginosa and Pichia fermentans were grown in Yeast Malt (YM) medium and the carotenoids produced identified as cryptoxa

3. Optimization of synbiotic yogurts with yacon pulp (Smallanthus sonchifolius) and assessment of the viability of lactic acid bacteria
Abstract The aim of this study was check the effects of sugar, yacon pulp and skimmed milk powder in the aroma, flavour, texture, appearance, overall impression and intent to purchase on synbiotic yogurts to optimize the formulation using Response Surface Methodology. The most accepted formulations were subjected to viability tests during 21 days by counting

4. Selection, isolation, and identification of fungi for bioherbicide production
Abstract Production of a bioherbicide for biological control of weeds requires a series of steps, from selection of a suitable microbial strain to final formulation. Thus, this study aimed to select fungi for production of secondary metabolites with herbicidal activity using biological resources of the Brazilian Pampa biome. Phytopathogenic fungi were isolat

5. Keratinolytic abilities of
Micrococcus luteus from poultry wasteKeratinolytic microorganisms have become the subject of scientific interest due to their ability to biosynthesize specific keratinases and their prospective application in keratinic waste management. Among several bacterial classes, actinobacteria remain one of the most important sources of keratin-degrading strains, however members of the

6. Stability of antimicrobial activity of peracetic acid solutions used in the final disinfection process
The instruments and materials used in health establishments are frequently exposed to microorganism contamination, and chemical products are used before sterilization to reduce occupational infection. We evaluated the antimicrobial effectiveness, physical stability, and corrosiveness of two commercial formulations of peracetic acid on experimentally contamin

7. Formulation of economical microbial feed using degraded chicken feathers by a novel Streptomyces sp: mitigation of environmental pollution
A new Streptomyces sp. IF 5 was isolated from the feather dumped soil and found to have a tremendous keratinase activity. The strain enabled the degradation of the chicken feathers very effectively in 60 h. The 16S rRNA sequence of 1474 bp long was submitted to the National centre for Biotechnological information. The keratinolytic activity in the culture me

8. Condicionantes da produção do tomate de mesa na região de Campinas,SP / Factors that affect tomato production in the region of Campinas,SP
The planting of tomato has a special relevance in Brazil, for its representation in area planted and the second most important vegetable crop growing area, with over three million tons. Thus, it is important to review how it is structured the production system and how it relates to the other links in the chain. The objective of this study was to characterize

9. Growth, cysts and kinetics of Borrelia garinii (Spirochaetales: Spirochaetacea) in different culture media
The aim of the present paper was to evaluate cyst formation and growth parameters of Borrelia garinii in a range of media differing in formulation and cost. A qualitative assessment of morphology and motility of B. garinii was conducted. All media were prepared aseptically and used in test tubes or Petri dishes. For each medium, the initial spirochete concen

10. Proposta de um protocolo para avaliação da viabilidade de conídios de fungos entomopatogênicos e determinação da proteção ao calor conferida a Beauveria bassiana e Metarhizium anisopliae pela formulação em óleo emulsionável / Establishment of a protocol to evaluate the conidial viability of entomopathogenic fungi and determination of heat protection to Beauveria bassiana and Metarhizium anisopliae by emulsifiable oil formulation
This study aimed to evaluate, under laboratory conditions, the influence of temperature and exposure time on the viability and virulence of Beauveria bassiana and Metarhizium anisopliae in suspensions prepared with pure conidia, rice plus fungus and in formulations of wettable powder and concentrated suspension in emulsifiable oil. Initially, an efficient an

Óleo essencial de eucalipto como bioestimulador da micorrização e do estabelecimento de mudas de eucalipto e sibipiruna em solo contaminado com cobre / Essential oil of eucalyptus as biostimulator of mycorrhiza and the eucalyptus and sibipiruna tree establishment in soil contaminated with copper
Ectomycorrhizal fungi (fECM) combined with the plant root system improve the absorption of water and nutrients, providing great plant growth, especially in environments with nutritional deficiency or degraded. Due to the fECM and plants live in mutualistic association, allows the fungal symbionts to be benefit, or at least tolerate, the secondary metabolites

12. Avaliação do glicerol proveniente da fabricação do biodiesel como substrato para produção de endotoxinas por Bacillus thuringiensis var. israelensis / Evaluation of glycerol derived from biodiesel production as substrate for endotoxins production by Bacillus thuringiensis var. israelensis.
The use of glycerol derived from biodiesel production as a substrate for the acquisition of biotechnology products is a promising alternative as an adequate disposal mean of this by-product. The bioinsecticide formulated with toxins from Bacillus thuringiensis has been used to control vectors insects of diseases, such as dengue, which affect millions of peop
