The antimicrobial activities of the isomers and enantiomers pinene were evaluated against bacterial fungal cells. agar diffusion test showed that only positive a- β-isomers active. minimal inhibitory concentration (MIC) microbicidal (MMC) these monoterpenes also determined, confirming exhibited activity all fungi bacteria tested with MICs ranging from 117 to 4,150 µg/mL. However, no was detected negative up 20 mg/mL. Time-kill curves (+)-a-pinene (+)-β-pinene highly toxic Candida albicans,...
Melissa officinalis L (lemon balm) is a traditional herbal medicine used widely as mild sedative, spasmolytic and antibacterial agent. This paper focuses on the analysis of chemical composition biological activities M. essential oil obtained under controlled harvesting drying conditions. An in-vitro cytotoxicity assay using MTT indicated that this was very effective against series human cancer cell lines (A549, MCF-7, Caco-2, HL-60, K562) mouse line (B16F10). possessed antioxidant activity,...
We have previously demonstrated that a linalool‐rich essential oil from Croton cajucara Benth presents leishmanicidal activity. In the present study, we demonstrate this inhibits growth of reference samples Candida albicans , Lactobacillus casei, Staphylococcus aureus, Streptococcus sobrinus, Porphyromonas gingivalis and mutans cell suspensions all them associated with oral cavity disease. The purified linalool fraction was only inhibitory for C. . Microbes saliva specimens human individuals...
Citrus fruits have potential health-promoting properties and their essential oils long been used in several applications. Due to biological effects described some citrus species this study our objectives were analyze compare the phytochemical composition evaluate anti-inflammatory effect of (EO) obtained from four different species. Mice treated with EO C. limon, latifolia, aurantifolia or limonia (10 100 mg/kg, p.o.) evaluated chemical induced inflammation (formalin-induced licking...
Hancornia speciosa Gomes (Apocynaceae) is a tree that widely distributed throughout Brazil. Its latex collected and used extensively to treat acne, warts, diseases related bursitis, inflammation. In this work, we describe the anti-inflammatory effects of latex.The from (0.06-1.3mg/kg, p.o.) reference drug acetylsalicylic acid (ASA, 200mg/kg, were evaluated in analgesia (formalin-induced licking, acetic acid-induced contortions, hot plate) inflammation models paw oedema, subcutaneous air...
The aim of this study was to evaluate the activity EO and its major components Ocimum basilicum var. Maria Bonita, a genetically improved cultivar, against fluconazole sensitive resistant strains Candida albicans Cryptococcus neoformans. Geraniol presented better results than EO, with low MIC (76 μg/mL C. neoformans 152 both strains). combination linalool, or geraniol enhanced their antifungal activity, especially strain (MIC reduced 156, 197, 38 μg/mL, resp.). ergosterol assay showed that...
The anti-corrosion effect and the antimicrobial activity of lemongrass essential oil (LEO) against planktonic sessile growth a sulfate reducing bacterium (SRB) were evaluated. Minimum inhibitory concentration (MIC) LEO its major component, citral, was 0.17 mg ml-1. In addition, both citral showed an immediate killing SRB in liquid medium, suggesting that is responsible for SRB. Transmission electron microscopy revealed MIC caused discernible cell membrane alterations formed electron-dense...

The use of agro-industrial wastes to produce high value-added biomolecules such as biosurfactants is a promising approach for lowering the total costs production. This study aimed using Rhizopus arrhizus UCP 1607, with crude glycerol (CG) and corn steep liquor (CSL) substrates. In addition, biomolecule was characterized, its efficiency in removing petroderivatives from marine soil investigated. A 22 factorial design applied, best condition producing biosurfactant determined assay 4 (3% CG 5%...
To investigate the potential antagonistic activity of Paenibacillus peoriae strain NRRL BD-62 against phytopathogenic micro-organisms and to determine physiological biochemical characteristics antimicrobial compound produced by this strain.Strain showed a broad inhibition spectrum with various bacteria fungi. Physico-chemical characterization that it was stable during heat treatment retained even after autoclave at 121 degrees C for 10 min. The also organic solvents, hydrolytic enzymes its...
Fonsecaea pedrosoi is a fungal pathogen that produces melanin. The functions of melanin and its possible influence in the protective immunological response during infection by F. are not known. In this work, treatment mycelia with proteases glycosidases followed denaturing agent hot concentrated acid left black residue. Scanning electron microscopy demonstrated processed melanized residue resembled very closely intact mycelium shape size. Melanin particles were also isolated from culture...
