The combined effect of initial amount of 18 h <i>L. rhamnosus</i> VT1 inoculum and incubation temperature on the growth of <i>Candida maltosa</i> YP1, an oxidative food spoilage yeast strain, was primarily modelled and studied by standard response surface methodology. This study resulted in the following linear regression equations characterising lag time and growth rate of <i>C. maltosa</i> YP1 in milk in competition with the potentially protective lactobacillus strain. Lag-phase of <i>C. maltosa</i> was strongly influenced by the amount of lactobacillus inoculum (<i>V</i><sub>0</sub>) and incubation temperature (1/<i>T</i>). The synergic effect of both these factors was also evident as results from the equation lag = –33.50 + 186.38 × <i>V</i><sub>0</sub> × 1/<i>T</i> + 512.27 × 1/<i>T</i> – 5.511 × <i>V</i><sub>0</sub> (<i>R</i><sup>2</sup><sub>(λ)</sub> = 0.849). The growth rate was sufficiently described by the linear relation: <i>Gr</i><sub>Cm</sub> = –0.00046 + 0.0033 × <i>T</i> – 0.0016 × <i>V</i><sub>0 (<i>R</i><sup>2</sup><sub>(Gr)</sub> = 0.847). On the basis of these equations, the mutual microbial interactions and the potential application of the lactobacillus strains to food protection are discussed.

В статье анализируются особенности восприятия лесного пространства башкирами. На основе языковых, фольклорных материалов сделана попытка раскрыть различные аспекты взаимоотношений лес - человек, образ леса в картине мира башкир. Как и в большинстве традиционных культур, в целом мифологический образ леса носит отрицательный характер. В фольклоре он часто описывается как тёмный, мрачный, неизвестный, таящий опасности, противопоставляясь обжитому и освоенному пространству селений. Лесной пандемониум также представлен в основном отрицательными персонажами. В целом образ леса в традиционной картине мира башкир предстаёт довольно неоднозначным. С одной стороны - это категория, связанная с потусторонним миром, неизведанная, «чужая» территория. С другой - лес издавна являлся источником различных благ - в виде строительного материала, пушнины, различных продуктов питания, укрывал от врагов. The article analyzes the features of Bashkirs' perception of the forest space. On the basis of the materials of the epos, folklore, folk ideas, an attempt was made to reveal the various aspects of the relationship between forest and man, the image of the forest in Bashkirs' world view. As in most traditional cultures, the mythological image of the forest as a whole is negative. In folklore, it is often described as dark, gloomy, unknown, fraught with danger, being contrasted with the inhabited and developed space of the villages. The forest pandemonium is also represented mainly by negative characters. On the other hand, in the domestic perception forest is valued for the benefits derived from it: shelter, food, protection from enemies. In addition, Bashkirs, distinguished by a developed aesthetic perception and contemplative thinking, appreciated its beauty, which is also reflected in folklore. In general, the image of forest in the Bashkirs' traditional view of the world appears rather ambiguous. On the one hand, it is the category associated with the other world, unknown, «foreign» territory. On the other hand, the forest has long been a source of various benefits - in the form of construction materials, furs, various food products, and it sheltered them from enemies.

The principle of breathable food packaging is to provide the optimal number of pores to transfer a sufficient amount of fresh air into the packaging headspace. In this work, antimicrobial microporous eco-friendly polymeric membranes were developed for food packaging. Polylactic acid (PLA) and polycaprolactone (PCL) were chosen as the main packaging polymers for their biodegradability. To develop the microporous films, sodium chloride (NaCl) and polyethylene oxide (PEO) were used as porogenic agents and the membranes were prepared using solvent-casting techniques. The results showed that films with of 50% NaCl and 10% PEO by mass achieved the highest air permeability and oxygen transmission rate (O2TR) with PLA. Meanwhile, blends of 20% PLA and 80% PCL by mass showed the highest air permeability and O2TR at 100% NaCl composition. The microporous membranes were also coated with cinnamaldehyde, a natural antimicrobial ingredient, to avoid the transportation of pathogens through the membranes into the packaged foods. In vitro analysis showed that the biodegradable membranes were not only environmentally friendly but also allowed for maximum food protection through the transportation of sterile fresh air, making them ideal for food packaging applications.
