Two mash-in programs were applied: (1) the Congress program, typical for basic raw materials, (2) a program with temperature optimized for phytase activity. Commercial preparations of 3-phytase (Finase P) and 6-phytase (Ronozyme) were used in the study. Monitored levels of selected fermentable sugars indicates a statistically significant effect of phytase addition on the glucose content in both mash-in programs used. The SEC-HPLC chromatography allowed to select a key polypeptide with an estimated molecular weight of 40 kDa, whose relative peak area decreases as a result of the applied mashincrease treatment with phosphorolytic enzymes, although this relation was not statistically confirmed in the analysis of free amino acids content. The analyses carried out also indicate that apart from the target molecules, namely phytate and inositol, the use of phytases in the process of buckwheat wort preparation slightly changes the profile of fermentable sugars and causes significant changes in the polypeptide profile of the final mash.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"51 1","pages":"33"},"PeriodicalIF":0.0,"publicationDate":"2021-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86871315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At world level this issue has been debated within the Convention on Biodiversity adopted in UN Conference of Rio de Janeiro and The International Convention regarding Genetic Resources of Plants for Alimentation and Agriculture. In Europe, the regulations in this field are made by the European Directive 98/95 EEC. Across time tomatoes have suffered a heightened process of genetic diversity, phenomenon caused by industrialized farming which is based on the use of very uniform varieties with high productivity. The extension of green agriculture, has led to the use of landraces, because they respond best to the traditional farming systems. In Western Europe organizations of peasants had been founded and, they are involved in different activities aiming at conservation of traditional forms of agriculture and the use of old varieties. In Romania the institutions with continuous preoccupations in the field of vegetal genetic conservation, especially landraces, are the Gene Bank from Suceava and UASMV Cluj-Napoca. By using conservation methods (in situ and ex situ), the genetic erosion surely phenomenon of vegetal genetic resources, implicitly tomatoes, is reduced, the future generations will benefit from valuable genetic resources.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"60 1","pages":"11"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78783096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of water availability on yields has been thoroughly researched, being one of the main limitative factors of the winter wheat yields. Starting from these considerations, during the agricultural years 2012-2018, a bi-factorial yield test was performed at Agricultural Research and Development Station (ARDS) Turda, for a period of seven years. The study explored the influence of the water status under the influence of two tillage systems and the climatic conditions specific for this area on winter wheat yields. In the field conditions of Turda during experimental interval, the soil tillage system had a rather small impact on the winter wheat yields. In the conventional system (CS) a reserve of accessible water is preserved better during the spring period, this being attributed to a better infiltration into the soil of winter precipitation (snow). In the conservative system (NT), the observed trend suggests that restoration of the ground water reserve is more difficult than in the CS but the loss of water in the CS is just as fast.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"125 1","pages":"22"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80382227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to provide an overview on recent advances related to the phytoremediation potential of plants from the genus Iris, in order to promote the use of these species in phytoremediation programs. According to the relevant literature, eight species from genus Iris present phytoremediation potential (I. dichotoma, I. germanica, I. halophila, I. lactea, I. latifolia, I. pseudacorus, I. sibirica, I. wilsonii). The studies addressed potential of plants to mitigate toxic metals/metalloids (As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Zn), excess of nutrients (P, N), pesticides, petroleum hydrocarbons, pharmaceuticals as well as dyes. Most studies focused on wastewater treatment and environments contaminated due to mining activities. Main hindrances in upscaling this green technology remain mitigation of toxicity stress in plants during remediation and the disposal of resulting contaminated biomass. In this sense, use of beneficial microorganisms to alleviate phytotoxicity effects and new valorization possibilities of contaminated Iris spp. biomass have been proposed recently. Designing an entire cycle that includes phytoremediation and sustainable value chains for contaminated biomass could prove feasible and should receive more attention.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"62 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90247677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the amount of CO2, using a volumetric method and the batch bioreactor to study the fermentation of a \"gluten free\" dough made of rice flour which is replaced with potato puree in proportion of 10%, 20%, 30%, 50%, 70% and water replaced with sauerkraut juice according to the material balance sheet. The results showed that the highest amount of CO2, of 1670 ml NaCl, was obtained in the sample where 10% of the flour was replaced with potato puree, sauerkraut juice was used and the dough moisture was 60%. Because the reference taken was the dough made from commercially available mixes combined with water, it was observed that the new materials used in this study are a good choice, being natural and healthy for the body, able to produce high volume gluten free products and being a waste recovery variant in the food industry.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"41 1 1","pages":"41"},"PeriodicalIF":0.0,"publicationDate":"2021-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85935254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploration and measurement of biodiversity yield copious amounts of information fragmented into numerous categories and types, following the pattern of life itself. We aim to review the potential of charting the plant diversity of woodlands, grasslands, marshlands, and other natural and semi-natural areas relevant to conservation by using low-altitude, low-cost, Earth Observation technology, such as small aerial drones, that captures images which can be mapped and analyzed. As this technology is new and quickly evolving, we limited the search to published research between 2012-2019. We have found applications for forestry, agro-forestry, horticulture, grasslands, ecological restoration, and other areas. In terms of technological progress, new hardware components and cameras and new software tools leverage drones’ power to deliver a greater quantity and quality of information. There are promising efforts to develop low-cost drone technology that facilitate better biodiversity conservation results. For analysis, software tools are also improving to take advantage of increases in computing power and artificial intelligence programming. Our findings serve as an introduction to low-cost teledetection for biodiversity conservation, with drones providing an advantage in monitoring habitats by increasing information quantity, accuracy, and ease of analysis with the aid of automation.","PeriodicalId":9380,"journal":{"name":"Bulletin of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca","volume":"61 1","pages":"64-68"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81512796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
