CITAB Labs

Evaluation of GHG emitted from crops and animal production systems. Assessment of environmental consequences when strategies for minimizing negative environmental impacts from animal and crop production, namely from organic and mineral amendments were used in agriculture. Monitoring of fundamental animal, plant and soil processes related to the carbon and nitrogen cycles.
The most important equipment on the lab include: 4 gas chromatographs, a portable photoacoustic gas analyzer and a chemiluminescence gas monitor which enable the analysis of greenhouse gases and other important gaseous compounds, such as: methane (CH4), nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2), carbon dioxide (CO2), ammonia (NH3) and hydrogen sulfide (H2S). In addition, there is a set of structures and facilities available for monitoring biological processes from the nitrogen and carbon cycles like dynamic and static chambers, reactors for composting, scale models of animal housing floors, large-volume chambers with temperature control and field facilities. These facilities, for example, allow the study step-by-step of animal manures applying a life-cycle (farm-scale) approach.

The main activities of the Agro-Environmental Technologies Laboratory, focuses on the role of autochthonous fungi in agro-industrial by products and effluents remediation and/or valorisation. It includes microbial fermentation of lignocellulose residue as a pre-treatment; enzyme production and saccharification for bioconversion into added value products; and myco-remediation of relevant effluents (e.g. wineries, olive oil mills and chestnut processing), alone or combined with non-biological processes. Also, the potential use of molds and yeasts as indicators of ecological integrity is of interest.

However the unit may also give support to other research animals from the campus such as pigs, poultry, sheep and fish. The research group develops research in vivo studies on the therapeutic and toxicological properties of plant extracts from Portuguese ethnobotanical floral species, such as Castanea sativa flower and Laurus nobilis extract, using animal models of cancers chemically induced and in the animal model of cervical cancer K14HPV16. The unit provides training programmes based on FELASA B courses for those caring experiments with animals.

In the last 30 years, the research group has been addressing different aspects of Microbiology: evaluation of antibiotic resistance mechanisms and virulence factors in bacteria isolated from different origins, namely human, animal and environment, and respective characterization of genes; study of microbial diversity using culture-dependent and culture-independent methodologies. Currently, the research team has been carrying out several studies on the use of natural compounds against important pathogenic bacteria (in planktonic state and biofilms) to find alternatives to the use of antibiotics or that act in synergy with the drugs used as a first choice, in the treatment of infections of different origins in a perspective of “One Health”.

In the Apiculture laboratory, the most varied aspects related to the honey bee are investigated, namely the characterization of its products (honey, pollen, bee bread, apitoxin, etc.), the role in pollination, the impact on ecosystems and the pathologies that affect them. Palynology as a tool for identifying the botanical origin of honey and pollen plays an important role in LabApis, which provides analysis services to beekeepers and companies in the sector with whom it has a strong connection. It also provides counseling services and specialized technical-scientific training courses.

AppClim develops R&D on climatology, mostly on climate variability, weather/climate extremes and climate change projections. Climate modelling and simulation are undertaken to generate state-of-the-art climatic information for targeted regions. Ensembles of climate models are used to take into account uncertainties, complemented by different anthropogenic radiative forcing scenarios and temporal evolution. Advanced bias correction methodologies are applied using observational datasets to ensure the adherence of climate data to local conditions. Bioclimatic and agroclimatic indices are produced for plant species and crop zoning. Mechanistic and stochastic crop models are also run, based on climate model outputs, to assess climate change impacts and risks, as well as to test the effects of different climate change adaptation strategies. Site-specific guidelines are provided for different crops and sectors envisioning effective adaptation and risk reduction. On-demand ad hoc analyses are also produced as decision support tools and solutions to foster resilient, climate-smart and sustainable food chains.

In the Cell Biology and Biochemistry Lab research is performed on two major topics: study of the cellular mechanism underlying the health effects of extracts from plants, agro-food co-products and mushrooms, of essential oils and of isolated phytochemicals, as well as of the study of nanoencapsulation of selected bioactive products for pharmaceutical and nutraceutical applications. Studies developed in this lab aim to contribute with knowledge related to the bioactive composition of autochthonous plants (e.g. Thymus mastichina, Thymus carnosus) and the molecular mechanism by which they modulate the physiological behavior of normal and tumoral cells. The results obtained also aim to demonstrate the phytochemical potential of some Portuguese endemic plants (some are endangered) in order to raise the awareness for its preservations; to value these plants and respective bioactive compounds as functional foods and/or functional ingredients, and to value the bioactive compounds present local agro-food co-products to reduce the wastes and increase its potential as added-value products.

The Ecotoxicology offers the possibility to work in the development and validation of biomarkers of exposure, in aquatic animals.
