Ekstrakcija eteričnih olj iz ingverja (Zingiber officinale)
Katja Svetek, 2019, undergraduate thesis

Abstract: Namen diplomske naloge je bil raziskati potencialne protimikrobne in antioksidativne učinke različnih ekstraktov, pridobljenih iz ingverja (Zingiber officinale), s ciljem potencialne uporabe naravnih izvlečkov v prehrambeni, farmacevtski, živilski in kozmetični industriji. Ekstrakte smo pridobili z različnimi metodami ekstrakcije; s Soxhletovo metodo, ultrazvočno metodo in superkritično ekstrakcijo s CO2. Vse ekstrakcije smo izvajali dve uri. Pri Soxhletovi in ultrazvočni ekstrakciji smo uporabili različna topila, s ciljem prepoznati razliko med ekstrahiranimi komponentami s pomočjo polarnega in nepolarnega topila. Različne metode ekstrakcije in različna topila vplivajo na količino pridobljenega ekstrakta in na vsebnost komponent, ki jih ekstrakt vsebuje. Zanimal nas je izkoristek ekstrakcij in kvaliteta pridobljenih ekstraktov. Uporabili smo dve spektrofotometrični metodi; radikalsko metodo DPPH za določanje antioksidativne aktivnosti ekstraktov in metodo za določanje vsebnosti totalnih fenolov. Za določevanje protimikrobnega učinka smo uporabili difuzijsko metodo z diski, protimikrobno delovanje smo testirali na grampozitivni bakteriji Staphylococcus aureus, gramnegativni bakteriji Escherichia coli in kvasovki Candida albicans. V diplomskem delu so prikazani rezultati ekstrakcij in analiznih metod, ki smo jih izvedli. Iz rezultatov je vidno, da je uporaba Soxhletove ekstrakcije in topila aceton najboljša izbira za dosego najvišjega izkoristka ekstrakcije. Antioksidativni potencial smo ovrednotili z DPPH metodo, s katero smo najvišji odstotek inhibicije opazili pri ekstraktu, pridobljenem s superkritično ekstrakcijo pri 135 bar. Najnižji odstotek inhibicije smo opazili pri obeh ekstraktih, pridobljenih s topilom heksan. Pri določevanju vsebnosti totalnih fenolov smo opazili najvišjo vsebnost v ekstraktu, pridobljenem z ultrazvočno ekstrakcijo, kjer smo kot topilo uporabili mešanico acetona in vode v razmerju 1:1. Najnižji delež vsebnosti totalnih fenolov smo opazili pri ekstraktoma, pridobljenima s topilom heksan; kar sovpada z najnižjim antioksidativnim potencialom. Nekateri pridobljeni ekstrakti so delovali protimikrobno proti C. albicans in S. aureus, medtem ko proti E.coli noben ekstrakt ni pokazal protimikrobnega učinka.

Biološka aktivnost ekstraktov origana ( origanum vulgare)
Klara Berlan, 2019, undergraduate thesis

Abstract: Namen diplomskega dela je bil preučiti biološko aktivnost ekstraktov origana (Origanum vulgare). Osredotočili smo se na njegovo antiokisdativno ter protimikrobno delovanje. S pomočjo različnih ekstrakcijskih metod in topil smo pridobili ekstrakte origana za nadaljnje analize. Ekstraktom smo določili antioksidativno učinkovitost, kjer smo uporabili radikalsko metodo DPPH in tako določili stopnjo inhibicije prostih radikalov. Nato smo s pomočjo plinske kromatografije z masno spektrometrijo merili vsebnost in koncentracijo osmih najbolj zastopanih komponent v origanu. Za ugotavljanje protimikrobnega delovanja smo uporabili difuzijsko metodo z diski. Zaviralno učinkovitost origana smo tako opazovali proti gram negativni bakteriji Escherichia coli, gram pozitivni bakteriji Staphylococcus aureus in glivi Candida albicans. Rezultati so pokazali, da je najboljši izkoristek ekstrakcije dala ekstrakcija po Soxhletu, kjer smo kot topilo uporabili mešanico etanola in vode (70 : 30). Prav vsi ekstrakti so pokazali visoko antioksidativno delovanje, najvišji % inhibicije dal ekstrakt pridobljen z ultrazvočno kopeljo. Tudi pri tem ekstraktu je bilo kot topilo uporabljena mešanica etanola in vode v razmerju 70 : 30. Kromatografske analize ekstraktov so pokazale, da je v vzorcih prisotna visoka vsebnost karvakrola, sledijo mu timol, linalol in karvon. Najvišje koncentracije so bile določene v vzorcih, pridobljenih z ekstrakcijo po Soxhletu in ultrazvočno ekstrakcijo, kjer je bila kot topilo uporabljena mešanica etanola in vode. Protimikrobno delovanje smo zaznali pri glivi Candida albicans, vendar ni bilo mogoče izmeriti premera inhibicijske cone. Ekstrakti so pokazali relativno nizko protimikrobno učinkovitost napram bakterijama Escherichia coli in Staphylococcus aureus. Razlog je lahko v slabem raztapljanju ekstrakta ali pa so posamezne molekule aktivnih komponent prevelike, da bi se difundirale skozi trden medij.

Comparison of methods for detection of four common nosocomial pathogens on hospital textiles
Sabina Fijan, Sonja Šostar-Turk, Urška Rozman, 2014, original scientific article

Abstract: Introduction: Although the most common vehicle for transmission of health-care acquired infections is the personto- person transmission route, the role of environment should not be ignored and hospital linen may contribute to the spreading of nosocomial infections. The contact plate method and swabbing are common methods for sampling microorganisms on textiles; however, results are available after two days as they are based on incubation followed by phenotypeidentification. An important alternative is using quick wash-off methods followed by PCR detection, which shortens the identification process from two days to a few hours. Methods: The following test microorganisms at different concentrations were inoculated onto textile swatches and dried overnight: Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Clostridium difficile. RODAC plate sampling as well as a non-destructive wash-off method for capturing microorganisms from the textilesusing a Morapex device were used. The elution suspension from the Morapex device was used for two methods. In the first method, classical incubation on selective media followed by phenotypic identification was used and in the second method DNA was extracted from the elution suspension followed by amplification and agarose gel electrophoresis to visualize amplified products. Conclusions: All chosen bacteria were found using all methods. However, the most sensitive proved to be detection using PCR amplification as we detected the sample with initial concentration of 102 cfu/mL inoculated onto the textile surface before drying. The final detectablerecovered bacterial concentration on textiles was up to 10 cfu/mL.

UGOTAVLJANJE VPLIVA PROBIOTIČNIH MIKROORGANIZMOV V KEFIRJU, NA POTENCIALNO PATOGENO BAKTERIJO KLEBSIELLA PNEUMONIAE
Sabina Novak, 2015, undergraduate thesis

Abstract: Kefir je z encimi bogato živilo polno telesu koristnih mikroorganizmov, ki ob rednem uživanju obnavljajo našo črevesno floro in povečujejo odpornost. V diplomskem delu smo preučevali probiotike ter kefir, in njegov zaviralni učinek na rast in razmnoževanje bakterije Klebsiella pneumoniae. Opisali smo tudi bakterijo Klebsiella pneumoniae in bakterijsko pljučnico. Diplomsko delo je sestavljeno iz dveh delov; teoretičnega in raziskovalnega. V teoretičnem delu smo opisali probiotike, kefir in njegovo sestavo, kamor sodijo kefirna zrna in kefiran. Predstavljena je bakterija Klebsiella pneumoniae in bolezni ki jih povzroča. V raziskovalnem delu smo preučevali, kako se potencialno patogena bakterija Klebsiella pneumoniae razmnožuje in raste v svežem mleku in ob dodani kulturi kefirnih zrn. Različne koncentracije bakterije Klebsiella pneumoniae smo dodali v sveže mleko ali sveže mleko s kefirnimi zrni in opazovali vpliv probiotičnih mikroorganizmov v kefirju. Na podlagi raziskovalnega dela smo potrdili hipotezo, da prisotnost kefirnih zrn v mleku vpliva na zmanjšanje preživetja bakterije K. pneumoniae. Iz tega lahko sklepamo, da ima kefir antibakterijski učinek.

Real-time polymerase chain reaction for quantitative assessment of common pathogens associated with healthcare-acquired infections on hospital textiles
Urška Rozman, Sabina Fijan, Sonja Šostar-Turk, Vid Mlakar, 2013, original scientific article

Abstract: A hospital environment may act as a significant reservoir for potential pathogens that can be transmitted with hospital textiles, which could represent a source of healthcare-acquired infections. Quantitative assessment of nosocomial pathogens with real time polymerase chain reaction (qPCR) on textiles can serve to verify the achievement of standards for textile hygiene of hospital laundry that assess the risk for acquiring hospital infection frominappropriately disinfected textiles. The aim of the study was to establish qPCR for quantitative assessment of selected common nosocomial pathogens (Clostridium difficile, Staphylococcus aureus, Klebsiella pneumoniaeand Pseudomonas aeruginosa) on hospital textiles and to compare the efficiency of the molecular method to the standard procedures for evaluating the bio burden of textiles in hospitals. This study demonstrated that presenceof nosocomial pathogens on hospital textiles can be confirmed with qPCR even where conventional techniques do not give any results. qPCR offers apossibility to confirm the presence of microorganisms in dead or viable but non-culturable states that cannot be detected by conventional sampling techniques but may still pose a hazard to public health.

Efficiency of four sampling methods used to detect two common nosocomial pathogens on textiles
Urška Rozman, Sonja Šostar-Turk, Sabina Fijan, 2012, original scientific article

Abstract: Detecting microorganisms on textiles is useful for many purposes, for example to determine the bioburden before laundering, assess the reduction in bacterial counts in connection with various laundry processes, or trace transfer routes in infection control investigations. Therefore a validated, reproducible and rational method is needed. For sampling microorganisms on textile surfaces the most commonly used method is the contact plate method using RODAC plates, first described by Hall and Hartnett followed by the swab sampling technique. Both methods can only capture microorganisms on the surface of the textiles while microorganisms that have penetrated into the deeper structure of the material will not be detected. In our research the contact plate method and the swabbing technique were compared with two wash-off methods. For the first wash-off method the destructive elution methodwas used, where microorganisms were eluted from the fabrics by shaking the fabrics for a certain time in an elution medium. For the fourth sampling method a nondestructive method that included a compact test device called MorapexŽ was used, which is based on forced desorption by pressing the microorganisms through the fabric without destroying the fabric. In our research, two types of microorganisms were included (Klebsiella pneumoniae andStaphylococcus aureus) that cause common nosocomial infections. The aim of this study was to compare the efficiency of the four sampling methods for detecting microorganisms on textiles and to determine the lowest concentration, which can still be detected. The percentage of microorganisms that were detected by both elution methods was substantially higher than by sampling of fabrics with the contact plate method or swabbing. It can be concluded that a nondestructive method using a modified MorapexŽ device can beapplied for quick determination of the hygienic condition of textiles.
