The aim of the research is to determine the microbiological stability of a protein-fat mixture of flax and sesame seeds that allows to correct its storage life. A protein-fat mixture has a high content of irreplaceable amino acids ВСАА and polyunsaturated fatty acids of w-3group, so it may be positioned as a component of nutrition for athletes. Flax and sesame seeds, cultivated in Ukraine, were used as research materials. The product was created, based on comminuted flax and sesame seeds in ratio 1:1. There were determined organoleptic (outlook, taste, smell, color) and physical-chemical (mass share of moisture, ash, protein, fat, acidic, peroxide, anisidine number) parameters of the product. There was determined the microbiological stability of the protein-fat mixture of the increased food value for athletes nutrition after 6 months. It has been proved, that as opposite to the control sample, the protein-fat mixture of the developed composition manifests its microbiological stability by the following parameters: content of mesophilic aerobic and facultative anaerobic microorganisms, molds, yeast, bacteria of the colon bacillus group and pathogenic microorganisms. The control sample that is comminuted flax seeds doesn’t manifest at the end of the storage term any correspondence of microbiological parameters by the content of mesophilic aerobic and facultative anaerobic microorganisms, molds, and bacteria of the colon bacillus group. This regularity is explained by the presence of lignans, sesamol and sesamoline, with preservative properties in the developed product. The obtained data may be used for reasoning recipes of products, based on the protein-fat mixture and correction of the food supplements ratio in them.

Water quality is an index of health and well being of a society. The pollution of water bodies is one of the areas of major concern to environment. In the present investigation an attempt has been made to evaluate the physical, chemical and microbiological parameters of Jhajjar rivulet of J&K. The study has been carried out by taking water samples at three different sites of the rivulet i.e. site 1, site 2 and site3. During the study, the physico-chemical parameters like pH, temperature, colour, total hardness, BOD, COD, DO, TDS and TSS in the water samples were studied. In microbiological examination, the presence of coliform in the water samples were studied.  It has been observed that there was a pollution load mostly at site 3 and slightly at site 2, it may be due to the release of huge quantities of sewage, effluent and manmade activities at the respective sites but the water from all the sites was found free from microbial contamination. It was concluded that water at site 1 is suitable for drinking as compared to site 2 and site 3 of the rivulet.

Mixing Behaviour

A 3-modular units facultative waste stabilisation pond was experimentally studied for performance and efficiency, in relation to its original design. The system was located at La Esmeralda, Melipilla a small town of the central region in Chile. It was found that treated water did not comply with treatment requirements due to overloading, flow dynamics, wrong assumptions regarding hydraulic mixing behaviour, and an overestimation of systems kinetics. The overloading in terms of flow led to a retention time which was 62% of original design. Furthermore, bad mixing further decreased the designed residence time to only 18%. The effluent did not meet the WHO faecal coliforms guidelines for unrestricted irrigation. The modelling work on the batch faecal coliforms and coliphage removal concluded that the effective decay rates were 1.359×1.087(T-20°C) day-1 for coliforms, and 0.439×1.044(T-20°C) day-1 for coliphages. The data was also well fitted by a model that incorporated solar radiation. However, model discrimination indicated that the dependence on temperature gave a better and more sensitive fit with the observed data. As the original design considered a lower faecal coliforms decay ratio, namely 0.7 day-1, the failure of the system had to relate more to mixing than overloading. Operational seasonal data (flow and retention time) and physical, chemical and microbiological parameters, and tracer studies are included. Some solutions for improving the La Esmeralda SWP performance are also discussed.

Rainwater Quality

The large temporal and spatial variability of rainwater quality, as well as the relatively small number of tests, makes the preliminary assessment of its economic exploitation difficult. Determining the relationship between the conditions and location of rainwater collection and rainwater quality would help indicate the range of options for rainwater use, as well as the parameters that require improvement. The aim of the presented article is to establish the physical, chemical, and microbiological parameters of different rainwater sources and, from the results obtained, determine the possibilities for its safe use in households. The research was carried out for two years. Samples of rainfall were collected from spring to fall from the following roofing materials: Concrete roof tiles, ceramic roof tiles, galvanized steel sheet, and epoxy-coated terrace. The physical, chemical, and microbiological quality were assessed on the basis of the pH, turbidity, electrical conductivity, the concentration of biogenic compounds, the concentration of chosen elements, the number of Escherichia coli, and the number of fecal streptococci. Significant bacterial contamination, decreased pH, and increased turbidity were identified in the water, depending on the parameters of the roofing washed by the rainfall and the intensity and frequency of precipitation.

Jenang, or what is often called dodol, slab, or gelamai, includes dense, chewy, half-processed products. Jenang, which was innovated from chayote, has a relatively short shelf life, which is only able to survive 3-5 days at room temperature (27ºC). Therefore, a good packaging is needed that can extend the shelf life of one of them is edible coating, which is the packaging of edible materials. Edible coating is one of the efforts that can be done to maintain the quality of a food. The purpose of this study was to determine the quality and estimation of chayote with and without edible jenang based on physical, chemical, and microbiological parameters. In this study using the analysis of water content, peroxide numbers, and total microbes and using the edible dip method. From the research it can be seen that the chayote jenang based on physical quality in edible samples can maintain the water content so that the texture remains elastic compared to without edible until the 15th day. Based on the chemical quality in jenang squash with edible, oxidation only occurred after storage on the 22nd day. Microbiological quality in the conjoined pumpkin jenang coated with edible or without edible was overgrown with a total amount of yeast mold ≥300,000 Cfu / g.

During its journey, the river water suffers natural or anthropic contamination, deteriorating its quality.  This impact can be qualified by determining the pollution Indexes (IPO). The work aimed to evaluate the spatial and temporal variation of the IPOs in the water of the high Andean micro-basin of the Chumbao River. The study included the section from 13°46'38.4” S, 73°15'32.3” W at 4079 m of altitude up to 13°35'26.4” S, 73°27'00.8” W at 2572 m of altitude. Physical, chemical, and microbiological parameters of the water were determined in 8 points along the river. These were grouped to calculate the IPO by mineralization (IPOMI), organic matter (IPOMO), suspended solids (IPOSUS), and trophic (IPOTRO) in the dry and rainy seasons. The indexes were categorized from 0.0 (not polluted) to 1.0 (highly polluted). The data were collected in triplicate and valuated through ANOVA and Tukey's test. It was found that IPOSUS, IPOMI, and IPOMO. The points near the head of the micro-basin reported no and low pollution; besides, they increased considerably in urban areas reaching highly polluted levels. In contrast, IPOTRO reported a eutrophic state, and that contamination levels were higher in the dry season. The waters of the Chumbao River above 2900 m of altitude and close to the head of the micro-basin do not show contamination, but in the urban area the index of pollution is high.

The objective of this work was to develop roll bread with partial replacement of wheat flour by malt bagasse (MB) and to evaluate the changes in their physical-chemical characteristics and microbiological parameters. Four formulations of breads were elaborated: one control without MB, and 3 formulations with partial replacement of wheat flour varying the MB amount in 5, 10 and 15%.  MB reduced the carbohydrate content of the dough; consequently, the calories of the bread rolls were also reduced. On the other hand, moisture, minerals and lipids contents were increased. The type of protein changed with the substitution of MB in the dough, but the amount of proteins was not altered. The lowest hardness values were observed in breads with 5% and 10% MB, being related to higher values of acidity in the dough. The increase in the mineral content of the dough was related to the darkening of the bread. All bread formulations showed microbiological quality within the limits established by Brazilian legislation for coliforms at 45 °C, Bacillus cereus and Salmonella sp. The formulation with 10% MB resulted in bread rolls with higher nutritional value, in terms of minerals, lower hardness and with a darker aspect all around when compared to the control bread, giving it an aspect of wholegrain bread.
