Box tree moth shows (Cydalima perspectalis) rapid spread in Europe. In Hungary it appeared first near to the western border of the country in 2011. In the eastern part of Hungary the first specimen was caught in 2015 with blacklight trap. Here we summarize its distribution in northern part of the Alföld (Great Hungarian Plain) on the basis of ...blacklight, pheromone and feeding attractant traps. We publish five new distribution data from northern part (4 from Hungary, 1 from Transcarpathia) and two from southern part of the Alföld. Beyond that the flight of three generations was observed both in the year 2015 and 2016.

The aim of the current experiment was to optimize the creation process of single cell protein on plant-based substrate solution with the intention to improve end-product turn out by means of adding vitamin solution. Based on the results of the fermentation processes of yeast strains, it was concluded that the vitamin-supplementation produced it...s greatest effect on the dry matter production, primarily on the K. marxianus DSM 4908 strain, while it was less beneficent when it comes to the figures of wet cell mass. In addition, it can be assumed that vitamin supplementation increased the maximum specific rate of growth (μmax) and decreased the generation time (tg) significantly. In the case of the K. marxianus yeast strain on corn steep liquor treated with vitamin-supplementation, the highest (μmax) and the lowest (tg) data were observed [(0.226 h-1) and (4.4 h), respectively]. Based on the results it was found that K. marxianus DSM 4908 is expedient to be applied on corn steep liquor medium in order to determine its suitability to produce additive for feeding.

Microelements are increasingly becoming into the focus of interest from both a point of view of nutrition science and feeding. An always growing care must be paid to the microelements coverage both in human and animal organisms because of incorrect alimentation habits and
unsatisfactory feedstuff nutrition value. For the increased supply of ...the micro-nutrients, enrichment or fortification with microelements can not only be realized with traditional foodstuffs and forage but there are already alternative ways such as single-cell proteins from yeasts directly enriched or fortified with microelements for the purpose.
We would like to draw the attention that the production of these items is more favourable in comparison with traditional foodstuffs or forage since yeasts are capable to multiply microelement levels compared to their original state, and establish organic bonds with them.
For this purpose, we explored and analysed the scientific literature, studies and research results on this subject, that is why we stressed the significance of yeasts, the features and health effects of certain microelements, as well as the possibilities for use of yeasts enriched with micro-nutrients.

The system of microcapital goes back 8 years in Hungary. Its strategy and practice developed at a time when really small enterprises emerged with little practise and even less capital. Specialists organising and executing programs started with microcapital with little experience. This programme provided the young and experienced an opportunity ...to gain experience they lacked, and seems to have been extremely successful.
