Salmo salar fish waste oil: Fatty acids composition and antibacterial activity
2020
Background and aims Fish by-products are generally used to produce fishmeal or fertilizers, with fish oil as a by-product. Despite their importance, fish wastes are still poorly explored and characterized and more studies are needed to reveal their potentiality. The goal of the present study was to qualitatively characterize and investigate the antimicrobial effects of the fish oil extracted from Salmo salar waste samples and to evaluate the potential use of these compounds for treating pathogen infections. Methods Salmo salar waste samples were divided in two groups: heads and soft tissues. Fatty acids composition, and in particular the content in saturated (SAFAs), mono-unsaturated (MUFA…
Chemical composition of the essential oil of Phagnalon saxatile (L.) Cass. (Asteraceae) growing wild in Southern Italy
2005
Abstract The essential oil from aerial parts of Phagnalon saxatile (L.) Cass. (Asteraceae) was obtained by hydrodistillation. The oil content was 0.15% (v/w), on a dry weight basis. The oil composition was analyzed by GC and GC/MS. Altogether 66 compounds were identified accounting for 93.2% of the oil. Sesquiterpenes represent the 23.9% of the oil. In the oil were also present fatty acids (21.8%) and waxes (19.3%). The oil shows no antibacterial activity.
Persistence of a mixed lactic acid bacterial starter culture during lysine fortification of sourdough breads by addition of pistachio powder
2020
Abstract Pistachio powder was added to flour or semolina to evaluate its contribution to increase the amount of lysine in bread. Bread production was carried out by sourdough technology using a selected 3-species (Lactobacillus sanfranciscensis/Leuconostoc citreum/Weissella cibaria) lactic acid bacterial (LAB) starter culture. All sourdoughs were subjected to a long-time fermentation (21 h) and showed levels of LAB around 109 CFU/g, indicating the suitability of pistachio powder for lactic fermentation. Yeasts were also detected, in particular in semolina trials. MiSeq Illumina technology was applied to investigate the bacterial composition of sourdoughs evidencing a different distribution …
Diversity and technological potential of lactic acid bacteria of wheat flours
2013
Abstract Lactic acid bacteria (LAB) were analysed from wheat flours used in traditional bread making throughout Sicily (southern Italy). Plate counts, carried out in three different media commonly used to detect food and sourdough LAB, revealed a maximal LAB concentration of approximately 4.75 Log CFU g−1. Colonies representing various morphological appearances were isolated and differentiated based on phenotypic characteristics and genetic analysis by randomly amplified polymorphic DNA (RAPD)-PCR. Fifty unique strains were identified. Analysis by 16S rRNA gene sequencing grouped the strains into 11 LAB species, which belonged to six genera: Enterococcus, Lactobacillus, Lactococcus, Leucono…
Draft Genome Sequence of Actibacterium mucosum KCTC 23349, a Marine Alphaproteobacterium with Complex Ionic Requirements Isolated from Mediterranean …
2014
ABSTRACT Strain R46 (CECT 7668; KCTC 23349), a nomenclatural type of Actibacterium mucosum , was isolated from surface seawater collected at Malvarrosa Beach (Valencia, Spain) in July 2008. The draft genome sequence of strain R46 (approximately 3.72 Mbp) contains 22 scaffolds and 3,619 protein-encoding genes, with a G+C content of 60.8 mol%.
Cilvēks un pārcilvēks F.V. Nīčes un F. Dostojevska ideju salīdzinājumā
2021
Bakalaura darbā „Cilvēks un pārcilvēks F.V. Nīčes un F. Dostojevska ideju salīdzinājumā“ aplūkota cilvēka un pārcilvēka jēdziena izpratne Frīdriha Nīčes un Fjodora Dostojevska filozofijā. Darba mērķis - caur pārcilvēka tēla analīzi izgaismot cilvēka eksistenciālo situāciju un iekšējo cīņu pārvarēt pašam sevi. Darbs ir iedalīts 3 nodaļās un 5 apakšnodaļās. Pirmajās divās nodaļās, caur Nīčes un Dostojevska pieredzi un dzīves gājumu, tiek aplūkotas abu filozofu cilvēka un cilvēka dzīves jēgas izpratne. Tādā veidā atklājot, kāda ir iespējamība un ar kādiem līdzekļiem var pārvarēt sevi, kā darbojas gribas un ciešanu attiecības. Trešajā nodaļās uzmanība tiek vērsta uz pārcilvēka idejas interpretā…
Mechanism of Antibacterial Activity via Morphology Change of α-AgVO3: Theoretical and Experimental Insights
2017
The electronic configuration, morphology, optical features, and antibacterial activity of metastable α-AgVO3 crystals have been discussed by a conciliation and association of the results acquired by experimental procedures and first-principles calculations. The α-AgVO3 powders were synthesized using a coprecipitation method at 10, 20, and 30 °C. By using a Wulff construction for all relevant low-index surfaces [(100), (010), (001), (110), (011), (101), and (111)], the fine-tuning of the desired morphologies can be achieved by controlling the values of the surface energies, thereby lending a microscopic understanding to the experimental results. The as-synthesized α-AgVO3 crystals display a …
«… Il tamburo di Lucano». Leopardi lettore della Pharsalia
2022
Dopo aver rapidamente ricostruito la lettura di Lucano compiuta tra ’700 e ’800, il contributo focalizza la sua attenzione sulla presenza della Pharsalia nella produzione leopardiana, cercando in particolare di verificare a partire da quale momento Leopardi mostri una conoscenza diretta del poema epico e soffermandosi su giudizi critici espressi a più riprese soprattutto nello Zibaldone. After having rapidly reconstructed the reading of Lucan between the 18th and 19th centuries, the contribution focuses its attention on the presence of Pharsalia in Leopardi’s production. The article tries to reconstruct from which moment Leopardi shows a direct knowledge of the epic poem and focuses on crit…
Mycobacterium tuberculosis rezistence pret antibakteriāliem preparātiem
2018
Tuberkuloze ir viens no vadošajiem nāves cēloņiem pasaulē. Par tuberkulozes izraisītāju uzskata M. tuberculosis. Praktiskajā daļā tiek veikti Zāļu jutības testi (ZJT) uz Lēvenšteina-Jensena barotnēm ar M. tuberculosis celmiem, lai noteiktu to rezistenci, kā arī tika apstrādāti rezultāti, kas bija iegūti un apkopoti SIA „RAKUS” Tuberkulozes un plaušu slimību centra Mikobakterioloģijas laboratorijas informācijas sistēmā(LIS). Statistikas analīzē tiek pierādīts, ka pasaulē un Latvijā saslimstības ar tuberkulozes gadījumu skaits samazinās un, savukārt, izārstēto cilvēku skaits paaugstinās. Starp visiem rezistentiem gadījumiem visbiežāk rezistence bija pret pirazinamīdu un izoniazīdu no pirmās r…
