Abstract
Cilj istraživanja bio je ispitati utjecaj različitog vremenskog intervala (1 minuta, 3 minute, 4 minute, 5 minuta i 7 minuta) pri najvećem stupnju snage mikrovalne pećnice (800W) na sterilizaciju in vitro hranjive podloge. Podaci su zabilježeni nakon 7 te nakon 14 dana. Svaki ispitivani tretman sadržavao je 5 Erlenmeyer tikvica. Provedena su dva ispitivanja: sterilizacija 50 mL MS hranjive podloge koja se nalazila u Erlenmeyer tikvicama bez prisutnosti staklene laboratorijske čaše u kojoj se nalazilo 400 mL destilirane vode te uz prisutnost staklene laboratorijske čaše (destilirane vode). Rezultati su pokazali da nije bilo velikog odstupanja u postotku steriliziranosti hranjive podloge između svih ispitivanih vremenskih intervala te da se dodatkom 400 mL destilirane vode u staklenu laboratorijsku čašu smanjio gubitak hranjive podloge procesom isparavanja. Najmanji postotak steriliziranosti zabilježen je pri vremenskom intervalu od 1 minute bez prisutnosti staklene laboratorijske čaše s destiliranom vodom ( 40% nakon 7 dan, 20% nakon 14 dana). Najmanja razlika izgubljenih mL hranjive podloge isparavanjem sa i bez prisutnosti staklene laboratorijske čaše u kojoj se nalazilo 400 mL destilirane vode zabilježena je pri sterilizaciji hranjive podloge u vremenskom intervalu od 4 minute (2 mL), dok je najveća razlika izgubljenih mL zabilježena pri tretmanu od 7 minuta (13 mL).
Abstract (english)
The aim of the study was to investigate the influence of different time intervals (1 minute, 3 minutes, 4 minutes, 5 minutes, and 7 minutes) at the highest degree of microwave power (800W) on sterilization of in vitro nutrient medium. Data were recorded after 7 and after 14 days. Each treatment tested contained 5 Erlenmeyer flasks. Two tests were performed: sterilization of 50 ml of MS nutrient medium contained in Erlenmeyer flasks without the presence of a laboratory glass containing 400 ml of distilled water and in the presence of a laboratory glass (distilled water). The results showed that there was no significant difference in the percentage of sterilization of the nutrient medium between all the time intervals tested and that the addition of 400 ml of distilled water reduced the nutrient loss by evaporation. The lowest percentage of sterilization was recorded at a time interval of 1 minute without the presence of a laboratory glass with distilled water (40% after 7 days, 20% after 14 days). The smallest difference of lost ml of nutrient medium by evaporation with and without the presence of a laboratory glass containing 400 ml of distilled water was observed during sterilization of the nutrient medium at treatment of 4 minute (2 m), while the largest difference of lost ml was observed at treatment of 7 minutes (13 m).
