Production of the Sicilian distillate “ Spiritu re fascitrari ” from honey by-products: An interesting source of yeast diversity
2017
The “Spiritu re fascitrari” (SRF) is a typical Sicilian distillate obtained from the by-products of traditional process of honey production. Although some alcoholic fermentation of honey based products have been described, the present research represents the first investigation on the yeast ecology and the physico-chemical characteristics of honey by-products subjected to an alcoholic fermentation followed by distillation. All samples collected during manufacturing process were analysed for the count of total, osmophilic and osmotolerant yeasts. The honeycombs and equipment surfaces showed the presence of yeasts that was 1.7 and 1.1 Log (CFU/mL), respectively. After enrichment, yeast popula…
Exposure to patulin from consumption of apple-based products.
2007
Patulin is a mycotoxin produced by species of Penicillium, Aspergillus and Byssochylamys. Several Scientific Committees classify patulin as mutagenic, embryotoxic and immunotoxic. It has been found as a natural contaminant of processed apple products and its presence may be indicative of the quality of fruit used in production. In this work, a method for the analysis of patulin is described, based on a simple liquid-liquid extraction with acetonitrile; patulin is analyzed using liquid chromatography with UV detection. Patulin identity was confirmed by GC-MS after its reaction with N-methyl-N-(trimethylsilyl)trifluoroacetamide. Fifty-three apple-containing products were analyzed and patulin …
Transforming adult education from neo-liberal to holistically inclusive adult education in Baltic States
2021
In this chapter, we explore the data of nation-wide adult education programmes in three Baltic states. These programmes incorporate informal learning elements from the perspective of active participatory citizenship (APC) and, therefore, this provision aims to enhance opportunities for young adults in vulnerable positions. We posit that the concept of active participatory citizenship (EduMAP Concept Note 2017) that aims at developing young adults’ politico-legal, socio-cultural and socio-economic proactiveness could be used for illustrating these educational programmes from the holistic education aspects (Jarvis and Parker 2005). Holistic approach to adult education (AE) denotes that knowle…
"OCTA" tirgus problēmas Latvijā
2019
OCTA ir sauszemes transportlīdzekļu īpašnieku civiltiesiskās atbildības obligātā apdrošināšana, kas Latvijā pastāv jau no 1997. gada, kopš 2004. gada OCTA sistēmu pārrauga, attīsta un stabilizē Latvijas Transportlīdzekļu apdrošinātāju birojs un kopš 2006. gada darbojas bonus-malus sistēma. Lai gan OCTA sistēma ir daudz attīstījusies un pilnveidojusies un šis ir 22. gads, kad OCTA darbojas Latvijā, tā tikai piecus gadus ir strādājusi ar peļņu. Bakalaura darba mērķis ir balstoties uz pieejamo informāciju, izpētīt OCTA nozares darbību, veicot apdrošināšanas izmaksāto atlīdzību un saņemto prēmiju izpēti, sniegt priekšlikumus nozares pilnveidošanai. Lai sasniegtu darba mērķi tika izpētīts vai OC…
OCTA apdrošināšanas problēmas un to risinājumi Latvijā
2016
OCTA Latvijā tika ieviesta 1997. gadā. 18 gadu darbības laikā OCTA apdrošināšanas nozare tikai 4 gadus ir strādājusi ar peļņu, turklāt 2015. gada pirmos 9. mēnešus OCTA noslēdza ar 7,3 miljonu eiro zaudējumu, kas ir 2,3 reizes lielāks nekā 2014. gada 9. mēnešos. Darba autors sava temata izvēli pamato ar to, ka ir nepieciešams izpētīt OCTA apdrošināšanas tirgu Latvijā un saprast, kāpēc OCTA tirgus Latvijā strādā ar zaudējumiem. Bakalaura darba mērķis ir izpētīt OCTA nozares darbību un pamatojoties uz datu analīzi noskaidrot kāpēc OCTA nozare 14. gadus ir strādājusi ar zaudējumiem, piedāvāt problēmu risinājumus un izteikt priekšlikumus problēmu novēršanai. Izvirzītā mērķa sasniegšanai autors …
Valorization of Wild Apple (
2018
The amplified production of fruit as well as burgeoning demand for plant-made food products have resulted in a sharp increase of waste. Currently, millions of tons of by-products are either being discarded or utilized rather ineffectively. However, these by-products may be processed and further incorporated as functional ingredients in making high-value food products with many physiological and biochemical effects. The chemical analysis of pomace oils using gas chromatography-mass spectrometry (GC/MS) and reversed-phase-liquid chromatography coupled with fluorescence detector (RP-HPLC/FLD) systems led to the identification and quantification of 56 individual lipophilic compounds including u…
Biodiversità nella dendroflora italiana
2013
Nella flora vascolare indigena d’Italia, costituita da circa 7000 taxa specifici e infraspecifici, quelli arborei sono rappresentati da un modesto numero di unità. Tra gimnosperme e angiosperme non si superano 200 specie. Diversificano e arricchiscono la dendroflora italiana specie legnose policormiche o arbustive che, con l’età e in particolari condizioni, possono assurgere a veri e propri alberi. Vi contribuiscono anche espressioni genetiche di classiche specie arboree variamente interpretate a livello tassonomico. La dendroflora qui esaminata si riferisce a 53 generi (7 gimonosperme e 46 angiosperme). I taxa specifici e infraspecifici sono 188 (21 gimnosperme e 167 angiosperme). Non poch…
Characterization of Pigments from <i>Malus domestica</i> Leaves for Wool Dyeing
2021
The study will present results of chemical analysis of mass spectrometry, evaluating the content of pigments in M. domestica leaves dyeing solution and in dyed woollen yarn nowadays. Yarn was dyed with fresh leaves of M. domestica tree. Before dyeing the yarn was treated with potassium aluminium sulphate mordant. Dyestuffs from the yarn were extracted in compliance with modified hydrochloric method of hydrolysis. Extracts were analysed by ultra high-performance liquid chromatography coupled with a diode array detector and mass spectrometry (UHPLC-DAD-MS) for identification of the pigments. Phytochemical screening of dyeing solution of the M. domestica leaves showed presence of dihydrochalco…
Apple (Malus domestica) and Tomato (Lycopersicum esculentum) Fruits Cell-Wall Hemicelluloses and Xyloglucan Degradation during Penicillium expansum I…
2004
We characterized the changes in cell-wall hemicellulosic polysaccharides and the hemicellulose-degrading enzymes associated with apple and tomato fruits infected by Penicillium expansum. Our results showed a reduction in the molecular mass of hemicelluloses, with this reduction being particularly notable in the xyloglucan associated with P. expansum infection. The activation of fungal beta-glucanases was also highlighted. Fruit xyloglucan endotransglucosylase/hydrolase (XTH)-specific activity decreased drastically during the infection process in both apple and tomato fruits. We suggest that XTH reduction during the infection might be related with the fungus attack mechanism. We also suggest…
Can the grey mould disease of the grape-vine be controlled by yeast?
2000
Botrytis cinerea has been found to be highly pathogenic to ‘Chardonnay’ and ‘Pinot noir’ cultivars of the grape-vine producing the characteristic grey mould symptoms within 7 days of inoculation to the vitro-plants. The yeast Pichia anomala (strain FY-102), isolated from apple skin, was found to be antagonistic to B. cinerea as it completely inhibited the appearance of the grey mould symptoms when grown together. The yeast was responsible for morphological changes such as coagulation and leakage of the cytoplasm of B. cinerea. The pathogen, when applied together with P. anomala, failed to bring about the grey mould symptoms on the grape-vine, suggesting that the yeast could control the expr…
