The subject Microbiology is taught in the third year of the Chemical engineering degree, its role in the curriculum is justified by the existence of multiple industrial processes in which microorganisms are used. The subject does not have a final exam, so it has several forms of partial evaluation of the process, among which is the integrative seminar. The objective of this paper is to show a new way of delivering the integrative seminar of Microbiology, demonstrating the link that exists between the subject and the Chemical engineering career. This new form consists of analyzing the content of an academic article that links the subject with the career. The seminar guide is presented, with all the aspects that students must develop. An example of analysis of a scientific article is shown, and the advantages of imparting the integrative seminar of this new form are presented, with respect to the classical form. It is concluded that this is a feasible alternative, which can be extended to other subjects of the career. [ABSTRACT FROM AUTHOR]

The behaviour of a batch of wheat flour packed in two materials (paper and polypropylene) and stored at 10°C and a relative humidity of 90% was evaluated. Every 30 days and until rejection the evaluations done were: moisture, dough properties (alveograph), baking test, viable total mesophilic bacteria counts, molds, viable yeasts, total coliforms, and entomology analysis for insect detection. For both type of package a significant increase of moisture happened during the storage but there were no significant difference between packs for the same time. In the alveograms P values had a significant increase at 90 day, L fluctuated in the paper sacks and increased with time in the PP, P/L only rose at 90 days in paper; W didn't fallow a defined tendency with time in paper, but in PP increased since 30 days and then stayed stable. The breads obtained during the whole period had a good quality and there were no significant differences between packing and time of storage. No infestation was detected in any type of packing in the storage time. The deterioration of the product occurred because of the increase in the microbiological counts. At 120 days the flour was rejected due to the high count of molds. [ABSTRACT FROM AUTHOR]

The aim of this paper is to identify common patterns in texts that function as Discussion of research articles in the area of Microbiology. With this purpose, a corpus of four texts was analyzed manually from the perspective of genre in Systemic Functional Linguistics. The schematic structure of the texts and the resources realizing it as configuration of meanings in the three metafunctions of language were explored. The analysis showed that the Discussion of research articles in this area realizes the genre warranty of the research, whose purpose is to legitimate the results found in the research in order to persuade the readers and to guarantee that they are pertinent to be incorporated to the body of disciplinary knowledge. The discourse-semantic resources found as relevant in the texts were the co-articulation of projection, a resource of the APPRAISAL system, and comparison, a resource of the conjunction system. Concede plus counter pairings were found only when the writer rejects possible objections of the readers. The resources found suggest that the new knowledge in Microbiology is integrated in a hierarchical structure of vertical knowledge. Due to the number of texts analyzed in this article, the results obtained are considered preliminary. [ABSTRACT FROM AUTHOR]

The development of the biotechnological industry has favored the need of having analytical tools, increasingly fast and powerful, which allows a more effective estimation of cell growth during bioprocesses. In this regard, turbidimetric techniques are very useful tools that fill such expectations and can be applied to life sciences. Systems for measuring turbidity are based on optical phenomena resulting from passing a beam of light through the culture medium. Light becomes scattered, due to the presence of foreign particles suspended in the medium under analysis thereby reducing the intensity of the emerging light. The manner in which a sample, suspended in medium, interferes light is then related to size, shape and composition of particles in suspension as well as the wavelength of the incident light. This paper describes the state of art of the development and use of turbidimetric techniques in cell culturing. Turbidimetric techniques differ one each other in geometry of the light detector used. The development of optical systems has led to an effective use in order to have information on various measurement fields including biotechnological processes. Therefore, turbidimetric methods constitute an alternative way for obtaining information and controlling biotechnological systems. [ABSTRACT FROM AUTHOR]

This paper reviews the case of a 45-year-old male, farmer, who presented with a localized lesion on the left foot (back and both sides) with increased volume, and fistulae of a 5-year evolution. Clinically, micetoma was suspected and micribiological studies identified the causative agent to be Actinomadura madurae. The radiography showed involvement (geodes) at the metatarsal bones. Treatment was initiated with trimethoprim sulfamethoxazole, diaminodiphenylsulphone and proteolytic enzymes, showing improvement after three months of treatment. [ABSTRACT FROM AUTHOR]

Wheat semolina packed in bags of two materials (multilayer paper and polypropylene knitted) was evaluated during room temperature storage. Insect detection, moisture, alveogram, cooking test and microbiology counts were evaluated. The semolina stayed in good condition up to 60 days for both type of package and deterioration occurred due to insect infestation at day 75, with more incidence in the polypropylene bags. The moisture of the semolina rose significantly during storage, but didn't surpass the maximal established limit (14%). For both types of bags there was a tendency to increase the average ordinate of maximum overpressure (P) and curve configuration ratio (P/L) and to diminish the average abscissa at rupture (L). The deformation energy remained stable. The technology behavior of the pasta was positive, being corroborated by the cooking test and the sensory evaluation. The microbiological counts remained stable during storage, and were similar for both bags. [ABSTRACT FROM AUTHOR]

The aim of this paper was to determine the microbiological behaviour of the fresh loin of pig packed in 70% of O2 and 30% of CO2 at 4°C. Loins in slice of 1 cm were packed in bags of two different container: poliamide/polietilene for modified atmosphere and polyvinyl chloride as pattern (normal atmosphere). The microbiological behaviour was carried out with psicotrophic microorganisms, total coliformys, fecal, fungus cont and viable yeasts, Salmonella, Lactobacillus, anaerobes microorganisms (Clostridios) and Staphylococcus aureus. Samples of slice loin and packed in modified atmosphere had a durability of 16 days at 4-6 °C, contrary to the sample packed in normal atmosphere which only lasted 5 days and that Lactobacillus was the gender with more capacity to grow in this product type.

Bamboos have a great economic importance due to their applications and their impact on the environment, mainly in protecting soil and watersheds. However, microbial communities associated with plantations of bamboo species grown in Cuba have not been characterized. This could help to validate its favourable environmental impact. Then, this paper aims to quantify, characterize and identify bacteria and filamentous fungi from soil in plantations of different species of bamboo. Plants, with more than 60 years of establishment from the bamboo collection in Cienfuegos Botanical Garden and young plantations of some of this species were sampled. In addition, soil samples of other plant species and uncultivated soil were included to compare the results. Microbiological analyses were circumscribed to cultivable microorganisms. It was found that the concentration of filamentous fungi was between 104 and 105 cfu/g and the bacteria concentration was between 106 and 107cfu /g, orders similar to those of other plant species sampled. We identified a total of 13 fungi genera and three bacterial families that show the diversity of soil microorganisms associated with different species of bamboo grown in Cuba. It is also the basis for further studies on its environmental impact. [ABSTRACT FROM AUTHOR]

The present paper shows the design, optimization, quality control for testing radiochemical purity, biological quality and realtime stability studies of a preparation of macroaggregated albumin from the controlled denaturation of HSA. An experimental design with a 2³ factorial plan was carried out in order to determine the ideal conditions for the preparation. The results showed that variations of albumin concentrations within the range of 5-15 mg/mL were irrelevant, however, the final pH of the mixture and the stirring speed were significant variables, as well as their interaction. Formulations with particles of diameter between 11 and 80 μ were obtained with the conditions selected in the experimental design which met the internationally established criteria for radiochemical purity, sterility and apyrogenicity. The biodistribution in experimental animals showed good quality lung images. The produced lots maintained physical, radiochemical, biological and microbiological stability during 90 days of storage at 4 °C. [ABSTRACT FROM AUTHOR]

Dielectric spectroscopy, also called electrochemical impedance spectroscopy, is traditionally used in monitoring corrosion and electro-deposition processes in the coating and characterization assessment of many kinds of sensors and semi-conductors. Its application in biotechnology for the characterization of cell cultures has, however, been notably expanded in the last decade. As a transductional principle, impedance has been applied in the field of microbiology as a means of detecting and quantifying pathogenic bacteria. This paper reviews the state-of-the-art of Impedance Microbiology, its progress and its applications for the detection of foodborne pathogenic bacteria, including the use of interdigitated microelectrodes, the development of chip-based impedance microbiology and the integration of impedance biosensors along with other techniques such as dielectrophoresis and electropermeabilization. Reference is made to basic components, definitions and principles of this technique, as well as to the explanation of the components and principles for cell culture design and the use of equivalent circuits for the analysis of the systems based on this alternative.

This research present the characterization bromatological, physico-chemical, microbiological and rheological borojo fresh pulp (Borojoa patinoi Cuatrec), which are of interest in the industrial processing of this pulp. Samples of intact borojo pulp were analyzed. These samples are coming from Los Ríos Province (Ecuador), the amount of pulp obtained was 82.3% respecting the whole fruit. The pulp presents a low pH and an important level of carbohydrates and calcium. The borojo pulp obtained was microbiological high quality, with microorganism counts inside the ranges normatively allowed. Rheological behavior is characterized by oscillatory and flow tests at different temperatures. The results showed that the borojo pulp behaves as a non-Newtonian pseudoplastic fluid, where the viscosity has a more elastic behavior than viscous similar to a gel. The results of the tests oscillatory and flow shows that temperature influenced on rheological behavior of borojo pulp. [ABSTRACT FROM AUTHOR]
