Research Interests


Probiotic olives

The main concept of the PROBIOLIVE - GA 24347 project is the production of olives, fermented with probiotic bacteria, isolated among the lactic acid bacteria colonizing the olive surface to act as starters in adequate amounts to improve consumer’s health. At the same time a better control of the fermentation process, early detection of faulty fermentation and spoilage and assessment of the time needed for fermentation completion will be achieved by monitoring the quality indices (e.g. volatiles) throughout the process with the use of advanced and emerging instruments (electronic nose) and tools (mathematical models).
A post-doc project ‘Elucidation and optimization of probiotic features of adventitious strains in olive brines and associated delivery systems’ [SFRH/BPD/67089/2009], Fundação para a Ciência e a Tecnologia, Portugal, has the goal of the functional product production containing Egyptian probiotic bacteria in adequate amounts to improve consumer’s health, without altering the quality characteristics of fermented olives.

New Protection

The overall objective of PTDC/AGR-ALI/117658/2010 Project is to generate fundamental knowledge on, and confirm applicability of adventitious lactic acid bacteria strains isolated from olive fermentation for eventual rational design of probiotic brined olives and olive pastes.

Bioactive peptides and human health

The plan of the post-doc project ‘Advanced studies on generation and activity of bioactive peptides from dairy sources’ [SFRH/BPD/64537/2009] Fundação para a Ciência e a Tecnologia, Portugal are the aim to generate potentially bioactive peptides from milk and whey proteins, via wild Lactobacillus strains obtained from several dairy ecological niches, and perform their overall characterization, including antimicrobial and anticarcinogenic (as triggered by aflatoxins) effects.

Microbiologia (PT)

Food Microbial Technology

No contexto das tendências actuais de desenvolvimento de alimentos funcionais e no âmbito do projecto Europeu Probiolives e de um projecto FCT de pós-doutoramento, tem vindo a ser avaliado o potencial probiótico das bactérias lácticas da azeitona de mesa, em Portugal e no Egipto, tendo em conta a composição e as características físicas da azeitona, enquanto veículo de suporte de probióticos para desenvolvimento de azeitona probiótica. No âmbito de um projecto FCT de post-doutoramento, avalia-se a capacidade de produção de péptidos bioactivos por bactérias lácticas com origem na matriz leite e derivados, bem como os mecanismos de acção na saúde, em particular o efeito anticarcinogenénico. O projecto NEW PROTECTION da FCT estuda os parâmetros probióticos e mecanismos associados de duas estirpes de Lactobacillus spp. já identificadas e seleccionadas.
