Technological properties of Lactobacillus plantarum strains isolated from grape must fermentation.

In this study, we have carried out an integrated (molecular, technological, and biotechnological) characterization of L. plantarum strains isolated from Apulian wines in order to combine the two protechnological features (MLF performances and must acidification aptitudes). Several parameters such as sugar, pH and ethanol tolerance, resistance to lyophilisation and behaviour in grape must were evaluated. Moreover, the expression of stress gene markers was investigated and was linked to the ability of L. plantarum strains to grow and perform MLF. Co-inoculation of Saccharomyces cerevisiae and L. plantarum in grape must improves the bacterial adaptation to harsh conditions of wine and reduced total fermentation time. For the first time, we applied a polyphasic approach for the characterization of L. plantarum in reason of the MLF performances. The proposed procedure can be generalized as a standard method for the selection of bacterial resources for the design of MLF starter cultures tailored for high pH must.

Publication date: Available online 19 September 2019Source: Seminars in Cancer BiologyAuthor(s): Annie Wai Yeeng Chai, Kue Peng Lim, Sok Ching CheongAbstractOral squamous cell carcinomas (OSCC) are a heterogeneous group of cancers arising from the mucosal lining of the oral cavity. A majority of these cancers are associated with lifestyle risk habits including smoking, excessive alcohol consumption and betel quid chewing. Cetuximab, targeting the epidermal growth factor receptor was approved for the treatment of OSCC in 2006, and remains the only molecular targeted therapy available for OSCC. Here, we reviewed the current ...

In conclusion, alcohol administration led to a significant influence on antioxidant system in the liver and kidney, but simultaneous intake of taurine, along with ethanol, partly attenuated the antioxidant changes in these organs. PMID: 31535630 [PubMed - in process]

The perovskites were mechanically ground and suspensions were subsequently prepared for washcoating. The physical and physicochemical modifications introduced in the mixed oxides after suspension, and their influence on the catalytic activity, were systematically studied in the s...

In this study, the ecotoxicity and surface activity of the composites of anionic surfactant sodium dodecylbenzene sulfonate (SDBS) and nonionic surfactant fatty alcohol-polyoxyethylene ether (AEO) in various mass ratios were assessed, and the correlation between ideal application properties and safe ecological perspective of the composites was explored. The ecotoxicity of individual SDBS, AEO, and SDBS/AEO mixtures was determined using the bioluminescence inhibition assay with Photobacterium phosphoreum, and the critical micelle concentrations (CMC) were measured by surface tension method and steady-state fluorescence spec...

CONCLUSIONS: Caregivers are engaging in a range of health risk behaviours; however, rates of hazardous alcohol consumption among the sample were high. Health promotion interventions targeted to address alcohol consumption should consider caregiver age and country of residence. So what? This study highlights the health risk behaviours caregivers engage in across a number of countries, and suggests that caregivers require further support to manage alcohol consumption in particular.

Authors: Stollhof LE, Obertacke U, Eschmann D, Proba S, Bühler M, Neumeier M, Bludau F Abstract OBJECTIVE: In Germany, among patients with minor head injury (MHI), the incidence of coexisting alcohol intoxication is indicated up to 50%. The neurological symptoms of patients with MHI may be caused or altered by alcohol intoxication, this could mislead to further, potential harmful, diagnostic steps or to misinterpretation of the symptoms and to non-execution of necessary treatments. In order to decide which patients need further diagnostics by CCT, S100B has been proposed as a potential selection criterion. On ...
