Cuirs et peaux de moutonsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Proteolytic and lipolytic moderately halophilic bacteria, originate from salt, may be found on salted sheep skins. Microbial spoilage of sheepskin usually result a from the failure to inactivate proteolytic and Iipolytic micro-organisms during skin preservation. To solve this problem, an effective inactivation method to be used in the leather industry was examined in this study. Protease and lipase activities of moderately halophilic Staphylococcus saprophyticus subsp. saprophyticus (TR5), Bacilius pumilus (DB5), Bacillus licheniformis (DBA2), Gracilibacillus dipsosauri (EK2) and Idiomarina loihiensis (GA3), isolated from salted sheepskins, were examined : Protease activity of each test isolate was determined by bath gelatin agar medium and casein digestion assay at 280nm. Lipolytic activity of each test isolate was determined by bath Tween 80 agar medium and measuring hydrolysis of p-nitrophenylbutyrate to p-nitrophenol at 405nm. Antibiotic sensitivities of test isolates to novobiocin, penicillin G, tetracycline, streptomycin, erythromycin, tobramycin, kanamycin and gentamicin were tested using disc diffusion susceptibility method. These isolates were found to be proteolytic, lipolytic and resistant to aforementioned antibiotics. inactivation effects of direct electric currents and alternating electric currents (0.5A, 1.0A, 1: 5A and 2.0A) on the mixed culture of these isolates were separately examined in liquid medium containing 25% NaCl. The mixed culture was killed in 1 minute by 0.5A direct current and 1.5A affernating current treatments. However, 0.5A alternating current and 1.0A alternating current treatments eliminated these micro-organisms respectively in 15 minutes and 10 minutes. In conclusion, electric current applications hold great potentiel for the eradication of proteolytic and lipolytic, antibiotic-resistant, moderately halophilic bacteria in leather industry.

- ECOTOXICITY STUDIES : Growth inhibition study of bacillus ferment filtrate extract on freshwater algae (pseudokirchneriella subcapitata) – Ready biodegradability – Stability and future applicationsNote de contenu : The concepts in beauty are constantly changing, bringing novel innovations in the cosmetic industry. The industry is also adapting to eco-friendly ingredients and packaging technologies, biodegradable cosmetics, environmentally safe products, and innovations to preserve the skin microbiome. We have earlier reported the extracellular metabolite from the probiotic strain Bacillus coagulans MTCC 5856 to have antimicrobial and skin protection activities. We examined the skin and environmental safety aspects of the ingredient in the present study. The studies were conducted as per the Organization for Economic Co-operation and Development (OECD) guidelines. Mutagenicity potential was studied by the Ames test. Environmental safety was conducted to assess the effect of the ingredient on microalgae and other zooplankton. LactoSporin was found to be safe in the ecotoxicity studies at a concentration of 100 mg/ L. It was readily biodegradable and was nonmutagenic. These results suggest that LactoSporin is an eco-friendly cosmetic ingredient with antimicrobial and skin-protecting properties.

Chlorure de polyvinyle
Concentration minimale inhibitrice (antimicrobiens)En microbiologie, la concentration minimale inhibitrice (CMI) est la plus faible concentration d'un produit chimique, généralement un médicament, qui empêche la croissance visible d'une ou de plusieurs bactéries. La CMI dépend du micro-organisme considéré, de l'être humain affecté (in vivo uniquement) et de l'antibiotique lui-même.
La CMI est déterminée en préparant des solutions du produit chimique in vitro à diverses concentrations croissantes, en incubant les solutions avec des groupes séparés de bactéries en culture et en mesurant les résultats en utilisant une méthode de dilution standardisée (agar ou microdilution). Les résultats se classent ensuite comme "sensible", "intermédiaire" ou "résistant" à un antimicrobien particulier en utilisant un point d'arrêt. Les points d'arrêt sont des valeurs convenues, publiées dans les directives d'un organisme de référence, comme le US Clinical and Laboratory Standards Institute (CLSI), la British Society for Antimicrobial Chemotherapy (BSAC) ou le Comité européen sur les tests de sensibilité aux antimicrobiens (EUCAST). On a pu constater des écarts importants au niveau des points d'arrêt de divers pays européens au fil des ans, et entre ceux de l'EUCAST et du CLSI.
Alors que la CMI est la concentration la plus faible d'un agent antibactérien nécessaire pour inhiber la croissance visible, la concentration bactéricide minimale (CBM) est la concentration minimale d'un agent antibactérien qui entraîne la mort bactérienne. Plus la CMI est proche de la CBM, plus le composé est bactéricide.
La première étape de la découverte d'un médicament est souvent le dépistage d'un médicament candidat de banque de données pour les CMI contre les bactéries d'intérêt. En tant que tels, les CMI sont généralement le point de départ pour de plus grandes évaluations précliniques de nouveaux agents antimicrobiens. Le but de la mesure de la concentration minimale inhibitrice est de s'assurer que les antibiotiques sont choisis efficacement pour augmenter le succès du traitement. (Wikipedia)

Pyrithione de zinc
Revêtements -- Additifs:Peinture -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : The authors look at why zinc pyrithione is worth investigating for protection either on its own or as a major component of a blend.
Recent changes in EU regulations have applied considerable pressure on some key active ingredients that until now have been the mainstays of European fungicide/algaecide formulations. In particular, reclassification of labelling of BCM and Diuron means that tried and tested BCM/Diuron formulations may soon be more limited in paint products.
Zinc pyrithione has a proven track record as a commercial antimicrobial agent and possesses all of the key features of a paint film fungicide/algaecide including broad spectrum activity (fungi & algae), low aqueous solubility, ease of formulation and ability to deliver long lasting protection. However, it has yet to be exploited fully in the exterior coatings sector as a major film fungicide/algaecide.
Given the small number of active ingredients currently available, zinc pyrithione is worth investigating for film protection either on its own (e.g. as a stand alone fungicide/algaecide) or as the major component of a blend.
Zinc pyrithione has the added advantage that it can be added to a paint formulation at concentrations of 3.0% by weight of wet paint without attracting any hazard labels on the packaging. Typical zinc pyrithione use levels are in the range 0.2-0.6% active and, therefore, significantly below the labelling threshold. This is important for an active that will be sold at consumer outlets.Note de contenu : - Introduction to Pyrithiones
