Streszczenie:

Primary screening of recent collections from the sea around New Zealand revealed a wide range of bioactivities, including antitumour, antiviral and anti-HIV activities. Seven marine organisms, including sponges and an ascidian, were examined to identify the active compounds responsible for these three type of biological activities. A chemical screening protocol was established for the dereplication and prioritization of antiviral natural product extracts, which was also applied to extracts with other bioactivities. A recent modification included HPLC analysis of the eluates from solid phase e

Actinomycetes and fungi were successfully isolated from both New Zealand and Malaysian marine invertebrates and classified as facultatively marine based on their ability to grow on both sea water and non-sea water media.

A clear preference of the actinomycetes for solid-state fermentation was observed, however, for fungi no significant preference was seen. Three isolates of Streptomyces spp., four Penicillium spp. and two Paecilomyces spp. whose extracts showed good cytotoxicity were selected for further investigation. A sma

Microalgae are promising microorganisms for the production of food and fine chemicals. Several species of microalgae are used in aquaculture with the purpose of transfer bioactive compounds up to the aquatic food chain. The main objective of this project was to develop a stress–inducement strategy in order to enhance the biochemical productivity of Nannochloropsis gaditana, Rhodomonas marina and Isochrysis sp. for aquaculture purposes having in account their growth and organizational differences. In this regard, two experiments were design: the first one consisted on the alteration of overall

Streszczenie:

Nos últimos anos, a procura por novos compostos para utilização pela indústria farmacêutica conduziu a um aumento dos estudos com espécies marinhas, uma vez que a sua aplicabilidade para fins terapêuticos é conhecida por parte de comunidades costeiras desde tempos remotos. O ambiente marinho tem evidenciado uma grande biodiversidade de espécies que demonstraram possuir a capacidade de sintetizar vários compostos com elevado potencial farmacológico. Assim, a indústria farmacêutica tem investido na extração, identificação e estudos de várias moléculas que constituem metabolitos de es
