Abstract:

Lactic acid bacteria were isolated from 10 samples of the traditionally fermented foods (5 samples of Vietnamese fermented pork roll and 5 samples of the salted field cabbage) and 5 samples of fresh cow milks collected from households in Vietnam. 22 strains of lactic acid bacteria were isolated for inhibition to Lactobacillus plantarum JCM 1149. Of these, only 2 strains including DC1.8 and NC1.2 have rod shape, the others have coccus shape. 7 strains showing higher antibacterial activity were selected for checking spectrum of antibacteria with indicator bacteria consistting of Bacillus subtili

Abstract:

Lipases are widely researched enzyme group because of their ability to catalyze a wide range of synthesis reactions. The aim of this doctoral thesis was to study and optimize fatty acid ester synthesis using lipases. The influence of enzyme choice, its preparation (immobilization), choice of substrates and reaction conditions on fat hydrolysis, biodiesel and phenethyloctanoate (flavour ester) synthesis reaction course and yield was studied. Enterobacter aerogenes lipase, which was developed in Lithuania, was immobilized and its properties were determined for the first time. Commercial lipases

Abstract:

Genetic selection to enhance muscularity in beef cattle is desirable to increase retail beef yield and the profitability of the beef industry. However it is unknown how selection for greater muscling will impact on intermediary and muscle energy metabolism which may influence certain attributes of meat quality. In order to assess these impacts of selection for greater muscling in cattle, the physiological mechanisms that underpin the increase in retail beef yield must be identified. This thesis examined the impact of selection for greater muscling on: retail beef yield; muscle glycogen; whole

Abstract:

Drosophila suzukii Matsumura è un parassita alieno invasivo dei frutti di bosco. Si è diffuso nelle Americhe e in Europa dalla fine degli anni 2000 con effetti economici negativi sui frutti di bosco. Questo parassita ha ricevuto un'attenzione speciale perché è una delle specie invasive di maggior successo del genere Drosophila, che utilizza diverse risorse alimentari e mostra un adattamento ecologico alle condizioni climatiche variabili. Il monitoraggio, come parte della gestione dei parassiti, è la chiave per controllare questo parassita. Quindi, è importante utilizzare le migliori esche e tr

Thesis (MSc Food Sc)--Stellenbosch University, 2000.<br>ENGLISH ABSTRACT: Maas is a traditional fermented milk drink of the indigenous people of Southern Africa and can thus be used to uplift the nutritional status of the South African population, especially for the lower income groups. Furthermore, the problem of lactose intolerance among the Black population can also be addressed by the consumption of Maas. The objective of this study was to screen mesophylic lactic acid bacterial strains (25 in total) from the University of Stellenbosch Food Science Culture Collection for suitable met

Abstract:

The use of health-promoting lactic acid bacteria (LAB) strains as starter or adjunct cultures for dairy productions could facilitate the in situ bio-synthesis of bioactive molecules during the fermentation process, increasing the interest towards dairy products as multifunctional foods. Currently, there is much research about genotypic and technological characterization of raw milk cheeses microbiota, which is rich in biodiversity and could be exploited for improving the sensory attributes and add healthy benefits to the cheese. Traditional Mountain (TM) cheese is made from raw cow’s milk and

Abstract:

The emerging evidence of preferential accumulation and long residence time of proteinaceous compounds in soil are counter to the traditional view that their structure is readily broken down through microbial activity. The shift in thinking of their residence time is, however, heavily influenced by physical and chemical protections in soil, representing an important change for understanding global biogeochemical carbon and nitrogen cycling. We investigated the accumulation patterns of proteinogenic amino acids for a long term (thousands of years) related to their sources and sinks. We found cle

The climate effects result in the control of fermentation process using the forgein species rather strigent. Moreover, the limited use of the native species in fermentation constrains their potential uses in fermentation business. Thus, in this study native species for fermentation were to be inoculated and preserved, and there efficiency in fermentation checked.
