Amyotrophic lateral sclerosis (ALS), a devastating progressive neurodegenerative disease, has no effective treatment. Recent evidence supports a strong metabolic component in ALS pathogenesis. Indeed, metabolic abnormalities in ALS correlate to disease susceptibility and progression, raising additional therapeutic targets against ALS.

The transmission of SARS-CoV-2 virus through aerosols has become an outstanding issue, where plenty of spread aspects are being analyzed. Portable Air Cleaners (PAC) with high-efficiency particulate air (HEPA) filters have been discussed as an adjunctive means for indoor environments coronavirus decontamination. This study evaluates, first, the air and surfaces SARS-COV-2 RNA contamination due to positive patients in households, and second, the efficiency of a PAC with HEPA filter to eliminate virus.

A novel and multidisciplinary observational analysis of atmospheric components in the Central Iberian Peninsula is presented here. PM concentrations and both populations of cultivable and non-cultivable microorganisms and concentrations of a wide range of trace elements associated have been simultaneously studied during multiple events along one year. The aim has been to characterize their potential relations and dependencies, and their seasonal, daily and hourly evolution.

Enterococci represent a considerable proportion of the microbiota in Manchego cheeses. In this study, a total of 132 enterococci isolated from good quality Manchego cheeses from two dairies at different ripening times were genotypically characterized and identified using molecular techniques. Representative isolates from the clusters obtained after genotyping were assayed for some enzymatic activities considered to have a potential role in cheese ripening, and for 2,3-butanedione and acetoin production, evaluation of odor intensity and appearance in milk and safety evaluation.

Twenty-seven Leuconostoc (Ln.) isolates from Manchego cheese were characterized by phenotypic and genotypic methods, and their technological abilities studied in order to test their potential use as dairy starter components. While phenotypic diversity was evaluated by studying the biochemical characteristics of technological interest (i.

Three molecular techniques, randomly amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR), pulsed field gel electrophoresis (PFGE) and differential display-polymerase chain reaction (DD-PCR) have been used to assess the intraspecific diversity of the lactic microbiota responsible for spontaneous malolactic fermentation (MLF) in Cencibel wines made at a cellar in Castilla-La Mancha (Spain). The results indicate that RAPD-PCR and PFGE are of value in typing this microbiota. Better discrimination was achieved by RAPD-PCR.

A total of 248 strains of predominant lactobacilli isolated during the manufacture and ripening of artisanal Manchego cheeses obtained from two dairies were obtained and the genetic diversity of 197 investigated using random amplified polymorphic DNA (RAPD-PCR). 51 isolates could not be lysed and were therefore not genotyped. Forty-two distinct RAPD patterns, grouped in six major clusters at a similarity level of 54%, were obtained.

Lactic acid bacteria from 18 Spanish goat cheeses produced by seven dairies were isolated to evaluate the genetic diversity of this bacterial community. 136 representative isolates were characterized by phenotyping and Randomly Amplified Polymorphic DNA (RAPD-PCR) analysis. Ten species were identified with predominance of Lactobacillus paracasei subsp.

The characterization of 23 Lactobacillus strains was performed. The strains were assayed for biogenic amine-forming capacity, hydrogen peroxide production, pectin esterase, cellulase and polygalacturonase production, growth rate, acidifying capacity and salt tolerance. Three strains were selected which belonged to the species, Lactobacillus brevis, Lactobacillus plantarum and Lactobacillus fermentum.

Genetic diversity of 323 strains of lactobacilli isolated from an Almagro eggplant manufacturing plant was analyzed by using random amplified polymorphic DNA (RAPD). Thirty-four distinct RAPD patterns were obtained with 95% of isolates grouped into 18 main clusters. Genetic diversity was higher in brines from season II, Lactobacillus plantarum and Lactobacillus fermentum/cellobiosus being the species with the greatest number of genotypes.

A study of the physico-chemical and microbiological processes taking place during the spontaneous fermentation of eggplant fruits that had been frozen after blanching revealed a delay in the onset of the active fermentation stage, which has been ascribed to the adverse effect of the freezing temperature employed on the lactic acid bacteria involved in fermentation. The species most affected by freezing were L. fermentum and L.

Forty-two lactobacilli were screened for their potential to degrade glucosinolate sinigrin. One of them, strain R16, demonstrated a high level of sinigrin degradation; it was identified as Lactobacillus agilis. The sinigrin degrading activity of L.
