“…The chemical composition of the essential oils consists of a mixture of compounds, in different percentages, which together give the specific bioactive properties. Thyme and oregano essential oils used were analysed with Agilent 6890 N GC-MS highlighting the main constituent compounds: carvacrol 57.4%, α-terpinene 32.4%, o-cymol 3.9%, for thyme essential oil [30] and thymol 64.4%, carvacrol 27.6%, limonene 3%, for oregano essential oil [31]. These compounds compositions are in agreement with those found in literature [32].…”

This research aimed to obtain biocompatible and antimicrobial nanofibres based on concentrated collagen hydrolysate loaded with thyme or oregano essential oils as a natural alternative to synthesis products. The essential oils were successfully incorporated using electrospinning process into collagen resulting nanofibres with diameter from 471 nm to 580 nm and porous structure. The presence of essential oils in collagen nanofibre mats was confirmed by Attenuated Total Reflectance -Fourier Transform Infrared Spectroscopy (ATR-FTIR), Ultraviolet–visible spectroscopy (UV–VIS) and antimicrobial activity. Scanning Electron Microscopy with Energy Dispersive Spectroscopy analyses allowed evaluating the morphology and constituent elements of the nanofibre networks. Microbiological tests performed against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans showed that the presence of essential oils supplemented the new collagen nanofibres with antimicrobial properties. The biocompatibility of collagen and collagen with essential oils was assessed by in vitro cultivation with NCTC clone 929 of fibroblastic cells and cell viability measurement. The results showed that the collagen and thyme or oregano oil composites have no cytotoxicity up to concentrations of 1000 μg·mL−1 and 500 μg mL−1, respectively. Optimization of electrospinning parameters has led to the obtaining of new collagen electrospun nanofibre mats loaded with essential oils with potential use for wound dressings, tissue engineering or protective clothing.

Leather products provide an ideal environment for microbial growth. In order to prevent the appearance and spread of various types of microorganisms, it is treated with selected biocides and even essential oils. The aim of this paper was to investigate the antifungal activity of selected essential oils applied to finished chromium tanned leather which is intended for leather fancy products. Antifungal activity was evaluated according to the PN-EN 14119: 2005 standard. Four finished chromium tanned leathers were tested, each of which was soaked in the following essential oils: tea tree essential oil at a concentration of 1, 2 and 5% and thyme essential oil at concentration of 1, 2 and 5%. The results obtained indicated that leather finishing with thyme essential oil showed the antimicrobial activity against Aspergillus niger, Chaetomium globosum and Candida albicans strains. The application of 5% thyme essential oil to leather samples inhibited the growth of all strains tested. Using tea tree essential oil on leather samples showed a antimicrobial effect only against Candida albicans. The application of essential oils in the leather finishing process may be an alternative to biocides used in the tanning industry.

“…Plants with bioactive properties are part of the important group of plants traditionally used to prevent and treat the development of fungi and bacteria [2,3]. Essential oils from plants are highly concentrated compositions in chemical compounds with important bioactivity, which have several properties: antiseptic, antibacterial, immunostimulant, regenerative, anticancer [4][5][6][7][8][9][10]. Essential oils are liquid, volatile, clear, or colored, soluble in lipids and organic solvents, having densities generally lower than water [11][12][13].…”

The purpose of this research is to obtain antifungal and antibacterial treatments based on natural compounds of essential oils of geranium, pine, and rosemary for cotton and leather linings to make leather, fur articles, and footwear. The main characteristic absorption bands for the functional groups of geranium, pine and rosemary essential oils were investigated by Fourier transform infrared spectroscopyattenuated total reflectance (FTIR-ATR). Microbiological antifungal test was performed in the presence of Candida albicans ATCC 10231 fungus and antibacterial activity was determined in the presence of Staphylococcus aureus ATCC 25923 (Gram-positive bacteria), and Escherichia coli ATCC 25922 (Gram-negative bacteria). The absorption method involved the inoculation of the bacteriological test inoculum directly on the treated samples. Microbiological tests have revealed a high antifungal and antibacterial activity of the essential oils of Aetheroleum pini sylvestris, Aetheroleum geranii, Rosmarinus officinalis on cotton and leather linings and the possibility to be used in various compositions for the treatment of different lining materials for gloves, caps, shoes or other articles with essential bioactive properties for health and environmental protection. KEY WORDS: natural compounds, antifungal and antibacterial treatments, cotton cloth lining, leather lining, health and environmental protection TRATAMENTE ANTIFUNGICE ŞI ANTIBACTERIENE PE BAZĂ DE COMPUŞI NATURALI PENTRU CĂPTUŞELI ARTICOLE DIN PIELEŞI ÎNCĂLŢĂMINTE REZUMAT. Scopul acestei cercetări este de a obţine tratamente antifungice şi antibacteriene bazate pe compuşi naturali ai uleiurilor esenţiale de geraniu, pin şi rozmarin pentru căptuşelile din bumbac şi meşină utilizate la confecţionarea articolelor din piele, blană şi încălţăminte. Principalele benzi de absorbţie caracteristice grupărilor funcţionale ale uleiurilor esenţiale de geraniu, pin şi rozmarin au fost determinate prin spectroscopie în infraroşu cu transformată Fourier -reflexie totală atenuată (FTIR-ATR). Testul antifungic microbiologic a fost efectuat în prezenţa Candida albicans ATCC 10231, iar activitatea antibacteriană a fost determinată în prezenţa Staphylococcus aureus ATCC 25923 (bacterie Gram-pozitivă) şi Escherichia coli ATCC 25922 (bacterie Gram-negativă). Metoda de absorbţie a implicat inocularea directă a inoculului de test bacteriologic pe eşantioanele tratate. Testele microbiologice au relevat o activitate antifungică şi antibacteriană ridicată a uleiurilor esenţiale de Aetheroleum pini sylvestris, Aetheroleum geranii, Rosmarinus officinalis pe căptuşelile din bumbac şi meşină, precum şi posibilitatea de a fi utilizate în diverse compoziţii pentru tratarea diferitelor materiale de căptuşeală pentru mănuşi, şepci, pantofi sau alte articole cu proprietăţi bioactive esenţiale pentru protecţia sănătăţii şi a mediului.
