After the editions of
Salamanca and Brasilia, the BioIberoAmerica Congress held its 3rd edition in
Braga – Portugal, April 7-9, 2022.
BioIberoAmerica 2022 is a unique congress that brings together scientists, entrepreneurs, industry and clinical representatives, who develop their research and work in the area of biotechnology.
This three-day event
featured oral presentations, poster sessions, debates, workshops and parallel
sessions. The topics covered the different areas of biomedicine and
biomaterials, agricultural, marine, food, environmental and industrial
biotechnology (bioenergy and bioremediation), molecular biotechnology, systems
biology and metabolic engineering, bioreactors, biocatalysis, separation
processes and biosensors, biotechnology, Nanobiotechnology, Bioinformatics,
Ethics and Society. In this edition, BioIberoAmerica 2022 participants were
invited to submit their papers on a new research topic – Sustainable Food
Systems in Iberoamerica.
Our colleagues from the INL
have participated in the congress, where they presented their papers related to
some of the articles developed under the SEAFOOD-AGE.
In other sections of the
website you can find the poster and the presentation made by our colleagues.
A new article related to the detection of E. coli O157 has been
accepted. On this occasion, the INL researchers have developed an isothermal
technique (RPA) combined with a sample treatment that allows the detection of
the bacteria on the same day the analysis is started, being able to see the
result with the naked eye by color change, or with the help of a UV lamp.
This new article is added to others that INL has been publishing throughout SEAFOOD-AGE project with the support of FEDER funds through the INTERREG Atlantic Area Programme:
Our partners, the Portuguese Institute for the Sea and Atmosphere (IPMA) together with the Marine Research Institute (IIM-CSIC), have just published their first Open access paper in the framework of the project.
Abstract: Fish discards and by-products can be
transformed into high value-added products such as fish protein hydrolysates
(FPH) containing bioactive peptides. Protein hydrolysates were prepared from
different parts (whole fish, skin and head) of several discarded species of the
North-West Spain fishing fleet using Alcalase. All hydrolysates had moisture
and ash contents lower than 10% and 15%, respectively. The fat content of FPH
varied between 1.5% and 9.4% and had high protein content (69.8–76.6%). The
amino acids profiles of FPH are quite similar and the most abundant amino acids
were glutamic and aspartic acids. All FPH exhibited antioxidant activity and
those obtained from Atlantic horse mackerel heads presented the highest
2,2-diphenyl-1- icrylhydrazyl (DPPH) radical scavenging activity, reducing
power and Cu2+ chelating activity. On the other hand, hydrolysates from gurnard
heads showed the highest ABTS radical scavenging activity and Fe2+ chelating
activity. In what concerns the _-amylase inhibitory activity, the IC50 values
recorded for FPH ranged between 5.70 and 84.37 mg/mL for blue whiting heads and
whole Atlantic horse mackerel, respectively. _-Glucosidase inhibitory activity
of FPH was relatively low but all FPH had high Angiotensin Converting Enzyme
(ACE) inhibitory activity. Considering the biological activities, these FPH are
potential natural additives for functional foods or nutraceuticals.
A Story of
Oamk being the only Finnish organization participating in the Atlantic Area Programme
and how they got to take part of Seafood Age Project was just published. The
story also includes a short introduction of Seafood Age project.
is published in ePOOKI, which is the forum for Oamk´s research and development
work publications. Publication is in Finnish, since the main target group of
ePOOKI is Oamk´s Finnish stakeholder companies and organizations.
partner, the International Iberian Nanotechnology Laboratory, is working to
improve food safety. They have just published a novel multiplex real-time RPA
method for the rapid detection of Listeria monocytogenes:
development of novel methods for the rapid detection of Listeria monocytogenes
is of high interest due to due to particular concerns about this its ubiquity,
resistance to sanitation processes and high mortality rates resulting from
evaluation of a novel multiplex real-time Recombinase Polymerase Amplification
(RPA) method including an internal amplification control is reported in the
paper released in volume 92 of Food Microbiology. The method performance was
compared to that of the European reference method (ISO 11290-1) for the
detection of the species in samples from 40 commercial dairy products. A limit
of detection below 10 cfu/25 g or mL sample was achieved, and values higher
than 90% were obtained for relative sensitivity, specificity, accuracy,
positive and negative predictive values and the index (kappa) of concordance.
Analysis was achieved within one working day, compared to the six days required
using the ISO method. Moreover, slight modification of the ISO 11290-1 method
to include secondary enrichment in half Fraser broth resulted in the
confirmation of all positive samples.
