Pecl, Matěj ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The bachelor thesis deals with the issue of quality assurance in series production. The main objective of the thesis is to research suitable quality control tools and application of selected tools to actual production. The thesis describes the selected series production and the quality requirements for such a production. Furthermore, the quality indicators monitored in the company where the selected production is located are described. A research of quality tools and a classification of the tools used in the company in terms of their use was conducted. Finally, the paper concludes with analyses of real data from the production, which were conducted using Pareto diagram and histogram The main cause of internal scrap, which is the screwing process, has been identified from these analyses. Corrective actions and monitoring of the situation were recommended. As the screwing process is unstable on other production lines, it was decided to change the product and process design.

Testing and optimization of protocols for removal of contaminants during DNA isolation from hibiscus blossoms
Brabcová, Martina ; Kubalová, Michaela (referee) ; Fialová, Lenka (advisor)
The Roselle (Hibiscus sabdariffa) is a widely used plant in food industry, especially in tea production. The hibiscus flower is rich in polyphenolic substances, which are a major problem in DNA isolation. This work deals with the modification of the CTAB isolation protocol to ensure concentration and purity of DNA sufficient for its amplification. DNA isolated according to the CTAB protocol did not have sufficient concentration and purity for amplification due to high contamination with polyphenolic substances. A procedure with double incubation of plant tissue in CTAB buffer containing 3% polyvinylpyrrolidone (PVP) was proposed to remove it. These isolates were successfully amplified. The effect of PVP concentration (1-5%) in CTAB buffer on the concentration and purity of isolated DNA was also investigated. PCR results showed that double incubation with CTAB buffer had a greater effect on the removal of polyphenolic compounds than changing the PVP concentration. Subsequently, the modified isolation protocol was also successfully used to isolate amplifiable DNA from commercial tea blends.

Development of active supplement with probiotics
Cveček, Jan ; Dzurická, Lucia (referee) ; Márová, Ivana (advisor)
Subject of this bachelor thesis was to investigate the antimicrobial activity of selected probiotic strains and determine how the probiotic growth is affected probiotic growth by prebiotics and essential oils. Probiotics are bacteria, which positively affect human health. They are mainly used in food industry as fermentation starter cultures, where they produce antimicrobial compounds that support resistance to pathogenetic bacteria during the fermentation process. In general, fermentation process is used to prolong the shelf-life of foodstuff. However, the applications of probiotics are very limited in food or other industry because probiotics are living organisms, so at least the industry tries to use their metabolic products. The method of encapsulation could support the usage of probiotics in other unusual ways. In experimental part of this thesis, the growth of probiotics was studied in both commercial MRS broth and in minimal broth, which could help with isolation of bioactive metabolic products such as lactic acid and bacteriocins. Additionally, the effect of prebiotic-inulin and essential oils from oregano and thyme on probiotics growth was investigated. In the second part of thesis, the content of lactic acid was analysed and antimicrobial activity of selected probiotic strains and effect of additives on activity was tested. Antimicrobial test discovered that prebiotics and essential oil from thyme enhanced the antimicrobial activity of tested samples. Also, the minimal broth was shown to be unsustainable for cultivation of used probiotics because selected strains exhibited small production of biomass and very low antimicrobial activity. In the third part, the probiotic strain was encapsulated with prebiotic and essential oil into alginate particles. Bacterial growth from the particles in MRS broth was investigated over period of 15 days. Results of this measurement were that probiotics were gradually released from particles over the period. Subsequently the potential use of these particles was proposed for further investigation.

Transformation of brewery industry waste by carotenogenic yeasts
Šnejdrlová, Kateřina ; Šimanský, Samuel (referee) ; Holub, Jiří (advisor)
Carotenoids are one of the metabolites produced by carotenogenic yeasts. These are valuable substances that are used in the food and pharmaceutical industries. The use of waste and by-product as substrate for cultivation of carotenogenic yeasts can reduce the overall cost of carotenoid production. The by-products of the brewing industry, due to their nutritional composition, appear to be suitable materials for use in the cultivation of microorganisms. The work is divided into theoretical and practical parts. The theoretical part focuses on the description of yeasts, their metabolites and individual substrates. The practical part focuses on the cultivation of carotenogenic yeasts on brewer's spent grain hydrolysate and on yeast extracts prepared from brewer's spent yeast. Following yeasts were used in the practical part: Cystofilobasidium infirmominiatum CCY 17-18-4, Sporidiobolus salmonicolor CCY 19-4-25, Sporobolomyces shibatanus CCY 19-9-6, Rhodotorula kratochvilovae CCY 20-2-26, Rhodotorula mucilaginosa CCY 20-7-31, Rhodotorula toruloides CCY 62-2-4. The results obtained in this work using advanced chromatographic methods suggest that treated brewer's spent grain and yeast extract prepared from brewer's spent yeast are suitable substrates for the cultivation of carotenogenic yeasts. The prepared yeast extract can also serve as a source of total nitrogen during cultivation, without negatively affecting the monitored parameters.
