  1. 1. The role of 6C RNA in gene regulation in mycobacteria

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Zhou Dexin; [2021]
    Keywords : Mycobacterium 6C RNA β-galactosidase activity;

    Abstract : The Actinomycetes, to which the Mycobacterium genus belongs contains many pathogens, such as Mycobacterium tuberculosis, which can cause tuberculosis, so it has become a focus area in modern molecular biology research. Mycobacteria contain many proteins and regulatory factors, including tRNA, ncRNA and sRNA, which can help bacteria better adapt to the environment. READ MORE

    Abstract : This report summarizes the work on the cloning, expression, and purification of PerR, a metal sensing regulator from Saccharopolyspora erythraea and the subsequent characterization using small angle X-ray scattering and other biochemical methods. The report aims to provide an insight into prokaryotic metal homeostasis, provide a better understanding of how PerR works and provide valuable information for the continued work on the crystallization of PerR.

  4. 3. Hur odlare genom odlingsåtgärder kan påverka mikrolivet i jorden : en litteraturstudie

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Maria Olsson; [2018]
    Keywords : mikroorganismer; mikrober; bakterier; svampar; gynna; nytta; odling; marktäckning; plöjning; organiskt material;

    Abstract : Jordens mikroliv har visat sig vara känsligt för de störningar som människan orsakar vid brukning av jorden. Ett rikt mikroliv är viktigt för jordens funktionalitet och antalet mikroorganismer kan ses som en indikator för jordens hälsa och kvalitet. READ MORE

  5. 4. Antibiotics from the nature - culturing of genetically talented bacterial isolates

    University essay from SLU/Dept. of Microbiology

    Author : Elinor Bertholtz; [2014]
    Keywords : antimicrobial; antibiotics; actinomycetes; secondary metabolites; NRPS; PKS-I; PKS-II; DTS;

    Abstract : Bacterial infections are a threat to the modern healthcare because of the increase of the antibiotic resistance that many bacteria have developed during the history of antibiotics that began with the discovery of penicillin 1928. In order to respond to the accumulating resistance, novel antibiotics have to be discovered constantly. READ MORE

  6. 5. Isolation of antibiotic producing microorganisms by screening for antibiotic resistance

    University essay from SLU/Dept. of Microbiology

    Author : Emma Nordenfjäll; [2014]
    Keywords : antibiotics; secondary metabolites; antibiotic resistance; isolation methods; rare-actinomycetes; unexplored ecological niches; diterpene synthases; non-ribosomal peptide synthases; type I polyketide synthases; type II polyketide synthases;

    Abstract : The worldwide use of antibiotics has rapidly increased since the discovery of the secondary metabolite penicillin made by Alexander Fleming in 1928. Since then, thousands of useful secondary metabolites of microbial origin have been discovered. About 80 % of these substances originate from Actinomycetes and in particularly Streptomyces species.
