Effekt av olika antimikrobiella medel på tillväxt av bakterier

Effect of various antimicrobial agents on the growth of bacteria (English)
Abstract [sv]

Syftet med projektet var att studera effekten av olika antimikrobiella produkter på bakterietillväxt.

Resultatet visade att Micrococcus luteus inte hade någon aktivitet i det 10% tunndrank-baserade LB-mediet (specifikt odlingsmedium för bakterien där tunndrank, en biprodukt från etanolindustri, har legat vid 10% koncentration) som användes under experimentet, medan antimikrobiellen Fermasure i höga koncentrationer nämligen 1600 ppm var effektivt mot bakterien Enterococcus faecium. Antimikrobiellen Vitahop vid koncentration av 25 ppm, hade framgång mot tillväxten av bakterien. Dessa antimikrobiella produkter kan användas vid odlingen av svamp för att inhibera tillväxten av bakterier.

Resultaten kan hjälpa till att fastställa doseringen av antimikrobiella produkter under svamptillväxt i stor skala där kontamination kan vara ett problem.

Abstract [en]

The aim of the project was to study the effect of various antimicrobial products on bacterial growth. The results showed that Micrococcus luteus had no activity in the 10% thin-rank-based LB medium (specifically culture medium for the bacterium where thin draff, a by-product of the ethanol industry, has been at 10% concentration) used during the experiment, while the antimicrobial Fermasure in high concentrations namely 1600 ppm was effective against the bacterium Enterococcus faecium. The antimicrobial Vitahop at concentration of 25 ppm, had success against the growth of the bacterium. These antimicrobial products can be used in the cultivation of fungus to inhibit the growth of bacteria.

The findings could help determine the dosage of antimicrobial products during fungal growth on a large scale where contamination can be a problem.
