Article
Cheeses are becoming a major safety and public health concern: cheeses available in supermarkets occasionally contain high histamine concentrations that can have negative effects on consumer health. In this study, we have attempted to assess the histamine distribution pattern in ripened cheeses, with the purpose of establishing a correct cheese sam...
Article
Background The BIOFISH 300 HIS method for the quantification of histamine in fish and fish products was validated by the AOAC Research Institute and granted Performance Tested MethodSM certification in 2016. The method is based on the use of an electrochemical reader (BIOFISH 300 device) together with disposable gold electrodes (Biotest) modified w...
Article
Background In 2018, the AOAC Stakeholder Panel on Strategic Food Analytical Methods approved SMPR 2018.009, for Lactose in Low-Lactose or Lactose-Free Milk, Milk Products, and Products Containing Dairy Ingredients, establishing the minimum recommended performance characteristics to be addressed during the evaluation of methods. Subsequently, AOAC I...

Background: Sulfites are some of the oldest and most widespread preservatives in our food supply. They are food additives that have antioxidant properties, but they are also recorded as allergens by the main international regulatory bodies on food safety because of their adverse health effect. Hence, sulfites maximum concentration in foodstuff is r...
Article
The Biofish-300 HIS method is a simple, reliable, and specific enzymatic biosensor for the detection of histamine. This technology is highly specific and selective and allows quantification of histamine in fishery products (fresh/frozen and processed) in a short time frame (2-3 min). Histamine in raw tuna, raw mackerel, raw sardine, raw anchovy, bo...
Article
Gluconate dehydrogenase (GADH) biosensors have been developed for the satisfactory determination of gluconic acid in wine samples, without any pretreatment. The biosensors have been fabricated by cross-linking immobilization of GADH onto screen-printed carbon electrodes, containing the mediator tetrathiafulvalene (TTF). Chronoamperograms have been...
Article
Phenol hydroxylase that catalyzes the conversion of phenol to catechol in Rhodococcus erythropolis UPV-1 was identified as a two-component flavin-dependent monooxygenase. The two proteins are encoded by the genes pheA1 and pheA2, located very closely in the genome. The sequenced pheA1 gene was composed of 1,629 bp encoding a protein of 542 amino ac...

The recruitment of vascular stromal and endothelial cells is an early event occurring during cancer cell growth at premetastatic niches, but how the microenvironment created by the initial three-dimensional (3D) growth of cancer cells affects their angiogenesis-stimulating potential is unclear. The proangiogenic profile of CT26 murine colorectal ca...
Article
The enzyme responsible for formaldehyde removal in industrial wastewaters by cells of Rhodococcus erythropolis UPV-1 was identified as a broad-specific aldehyde dehydrogenase (EC 1.2.1.3). The enzyme was purified to electrophoretic homogeneity from ethanol-grown cells with a specific activity of 19.5 U mg−1 protein and an activity recovery of 56%....
Article
Phenol and formaldehyde removal was tested in two different wastewater samples obtained from a local phenol–formaldehyde resin manufacturing company using a strain of Rhodococcus erythropolis isolated in our laboratory from a phenol polluted site on the Gernika estuary. This strain is capable of growth on phenol as the sole carbon and energy source...
