Novel Protease from Aspergillus tamarii URM4634: Production and Characterization Using Inexpensive Agroindustrial Substrates by Solid-State Fermentation

This study reports the protease production from Aspergillus tamarii using agroindustrial residues as substrate for solid-state fermentation (SSF) and biochemical characterization. The highest protease production was obtained using wheat bran as substrate at 72 h fermentation with maximum proteolytic activity of 401.42 U/mL, collagenase of 243.0 U/mL and keratinase of 19.1 U/mL. The protease exhibited KM = 18.7 mg/mL and Vmax = 28.5 mg/mL/min. The optimal pH was 8.0 and stable in a wide pH range (5.0 - 11.0) during 24 h. The optimum temperature was 40°C. The proteolytic activity was inhibited by Cu2+ (33.98%) and Hg2+ (22.69%). The enzyme was also inhibited by PMSF (65.11%), indicating that is a Serine Protease. These properties suggest that alkaline protease from A. tamarii URM4634 is suitable for application in food industries and leather processing. Additionally, the present findings opened new vistas in the utilization of wheat bran and other effective agroindustrial wastes as substrates for SSF.

American Journal of Plant Sciences 2015年第9期6卷 1594-1606页

The foliar application and seed Ca + B, Mo + P and Stimulate? in peanut, despite being a practice used long ago, few studies have conclusive results, and then this research was to evaluate the physical and physiological quality peanut seeds from the process of application of fertilizers and bio-stimulant. The design was completely randomized, with seed from peanut plants subjected to the use of three products (Ca + B;Mo + P and Stimulate?), two types of applications (via leaf and seeds), growing with PK and absolute control, following a factorial arrangement of [(3 × 2) + 2]. For the dimensions (length and width) of seeds, as well as the thousand seed weight and number of seeds per pod, data were submitted to descriptive statistics, calculating the mean, standard deviation, variance and coefficient of variation of the data obtained. The application of fertilizers, bio-stimulants and groundnut seeds increases germination of seeds produced, causes more seedlings that are vigorous and reduces the percentage of abnormal seedlings.

This study aimed to estimate genetic parameters of Turiaçu pineapple clones using mixed models;and estimate genetic correlation coefficient between traits, to provide important information to breeding programs. For this, 19 pineapple plants were visually selected and its slips were collected and planted in a single environment and nine traits were evaluated. The genetic parameters of most evaluated traits presented significant differences between the 19 clones. Some traits, such as Fusarium wilt resistance, showed high magnitudes of heritability. Clones did not differ in relation to total titratable acidity (TTA) and total soluble solids (TSS). However, these traits, which have implications to fruit quality, showed to be negatively correlated to fruit mass (-0.46 and -0.67). The results indicate that the population of Turiaçu pineapple is suitable for selection, especially for Fusarium wilt resistance. Also, Turiaçu clones can be used in breeding programs of pineapple.

Migration for Love？ A Study of Brazilian Women Married to Swiss Men

Psychology Research 2014年第1期4卷 48-59页

作者： Flavia de Maria Gomes Schuler Cristina Maria de Souza Brito Dias Universidade Catolica de Pernambuco (UNICAP) Universidade Federal Rural de Pernambuco (ufrpe) Pernambuco Brazil Universidade Catolica de Pernambuco (UNICAP) Pernambuco Brazil

We are living in the age of globalization, characterized by rapid social change and great technology advances. Intercultural marriage is nothing new, since the barriers to such unions are diminishing; consequently, they are gaining space. In Switzerland, for instance, 49% of all marriages that happened in 2007 were intercultural. Brazilian women appear in second place with whom Swiss men marry most. The general objective of this research was to investigate the adaption of Brazilian women who are married with Swiss men, as well as the repercussions of this marriage in their lives. The specific objectives were: the reasons that made them migrate and marry with a foreigner, the obstacles and enabling factors of the coexistence, the process of adaption to a foreign country, to the family-in-law, and to marriage by itself. The participants were 12 Brazilian women who live in the German part of Switzerland. They responded to an interview, focused in the objectives of the study. It was found that apart from the reasons for the migration, all of them experienced difficulties because of cultural differences, in the social environment as in marriage and parenting.

Sugarcane is used worldwide for sugar, ethanol and energy production. In Brazil, the shift from burned to unburned harvest systems resulted in increases in nitrogen fertilization rates, which can impact root architecture and biomass. The expectation is also an increase in sugarcane biomass. The study hypothesized that high N rates applied to sugarcane fields increases root growth and N stored in roots, promoting higher biomass and N accumulated in shoots. Two experiments were set up in Southeastern Brazil, on a Typic Kandiudox (TK) and Rhodic Eutrudox (RE). Four treatments were studied 1) N application in the plant-cane (0 and 120 kg·ha-1 N) and 2) N application in the ratoon (0 and 150 kg·ha-1 N). The shoot biomass and the root density (by the core method up to 0.6 m) were evaluated over the first ratoon crop cycle, and the N content in those compartments was also examined. There was no carry over effect on N applied at planting in root and shoot biomass in the ratoon crop cycle. At the RE site, the ratoon N fertilization increased root density in the superficial soil layer (0 - 0.2 m) and close to the plants (<0.3 m). The effect of N addition on root biomass, and biomass and N accumulated in shoot was limited in both sites. Increasing N rates in unburned sugarcane fields do not consistently increases root and shoot biomass under Brazilian field conditions.
