The biosynthesis of nanomaterials mediated by bacteria, yeast, molds, and microalgae is attracting interest as fascinating field for future ‘green’ breakthrough synthesis of nanomaterials for real applications. In addition to nanoparticles, some microorganisms have shown the capability to biosynthesize unique nanostructured materials of microbial o...
The activities undertaken within the EcoNet project aim at the design and development of an integrated system for the monitoring of changes in surface waters natural status based on different sensoristic techniques. The proposed integration approach combines ground measurements and hyperspectral satellite images. The promising dialogue that occurs...
EcoNet is a joint project between the Italian Space Agency (ASI) and the Institute of Nanostructured Materials of the National Research Council of Italy (CNR-ISMN) with the participation of University of Tor Vergata (UTOV) that aims to develop an integrated sensor-driven system managed by artificial intelligence (AI) for monitoring surface waters n...
With over 6 million coronavirus pandemic deaths, the African continent reported the lowest death rate despite having a high disease burden. The African community’s resilience to the pandemic has been attributed to climate and weather conditions, herd immunity, repeated exposure to infectious organisms that help stimulate the immune system, and a di...
The worsening of air quality is an urgent human health issue of modern society. The outbreak of COVID-19 has made the improvement of air quality even more imperative, both for the general achievement of major health gains and to reduce the critical factors in the transmission of airborne diseases. Thus, the development of solutions for the filtrati...
Major foodborne disease outbreaks have clarified the close interconnection and interdependence between the health of humans, animals, and the environment [...]
The widespread agricultural use of the phenylurea herbicide Diuron (DCMU) requires the investigation of ecotoxicological risk in freshwater and soil ecosystems in light of potential effects on non-target primary producers and a heavier effect on higher trophic levels. We used microalgae-based fluorimetric bioassays for studying the interferences on...
Recent works have demonstrated that particulate matter (PM) and specific meteorological conditions played an important role in the airborne transmission of the SARS-CoV-1 and MERS-CoV. These studies suggest that these parameters could influence the transmission of SARS-CoV-2. In the present investigation, we sought to investigate the association be...
The widespread presence of plasticizers Bisphenol B (BPB) and Bisphenol A (BPA) in food contact materials, medical equipment, and common household products is a toxicological risk factor for health due to internal exposure after environmental dietary exposure. This work describes the use of an amperometric cytosensor (i.e., a whole cell-based amper...
In the last decade, biochemical sensors have brought a disruptive breakthrough in analytical chemistry and microbiology due the advent of technologically advanced systems conceived to respond to specific applications. From the design of a multitude of different detection modalities, several classes of sensor have been developed over the years. Howe...
Nanomaterials are increasingly being used in new products and devices with a great impact on different fields from sensoristics to biomedicine. Biosynthesis of nanomaterials by microorganisms is recently attracting interest as a new, exciting approach towards the development of ‘greener’ nanomanufacturing compared to traditional chemical and physic...
The dairy industry’s silos is a critical point in the safety and quality control system. However, limited scientific evidence is available on measurement agreement between the milk analyses done by official control bodies and the self-monitoring analyses done by milk processing industries. Milk production data from a milk processing plant were coll...
Simazine is an herbicide that is able to contaminate surface waters, ground waters, and milk/dairy products, thus posing concerns in both environmental health and food safety. A yeast-based bioprobe was utilized to detect simazine in spiked real samples of livestock drinking water and raw cow's milk. Yeast aerobic respiration was taken as short-ter...
Current Hazard Analysis Critical Control Points (HACCP) approaches mainly fit for food industry, while their application in primary food production is still rudimentary. The European food safety framework calls for science-based support to the primary producers’ mandate for legal, scientific, and ethical responsibility in food supply. The multidisc...
This mini-review covers the newly developed biosensoristic and chemosensoristic devices described in recent literature for detection of contaminants in both environmental and food real matrices. Current needs in environmental and food surveillance of contaminants require new simplified, sensitive systems, which are portable and allow for rapid and...
A study on the acute and chronic effects of the herbicide diuron was carried out. The test, basing on a yeast cell probe, investigated the interference with cellular catabolism and possible self-detoxification capacity of Saccharomyces cerevisiae. Aerobic respiration was taken as the toxicological end-point. Percentage interference (%) with cellula...
This study was carried out with the yeast system to understand the acute and chronic effects of diuron aka DCMU (herbicide inhibiting the photosystem II in the plants). The test investigated the possible self-detoxification capacity of yeast cells: aerobic respira- tion was taken as the toxicological end-point. Inhibition was shown by increased dis...
Aerobic catabolism of S. cerevisiae (cell respiration) is a rapid, cost-effective, and reproducible toxicological endpoint of the whole cells biosensor. To increase the signal intensity, a protocol for the immobilization and modification of the yeast cells is described. In particular, the enzymatic treatment of the immobilized yeast cells allows re...

Questions
Question (1)
Hello, I'm starting to work with commercial dried probiotic cultures (belonging to Lactobacillus, Bifidobacterium and Streptococcus genera) and I need to rehydrate these bacteria with the highest possible percentage of viability.
Could you please help me and suggest me a good (and detailed) rehydratation protocol?
Thank you
