Abstract This study aimed to explore the anti-bacterial and anti-fungal activities of extracts from different parts of plants in the Zingiberaceae family. The inhibitory rate, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) of leaf and stem, and root and rhizome extracts from Alpinia katsumadai Hayata, Alpinia oxyphylla Miq × Alpinia henryi K. Schumann, Alpinia oblongifolia Hayata, Alpinia nigra (Gaertn.) Burtt, Amomum villosum Lour, Alpinia zerumbet (Pers.) Burtt. et Smith and Alpinia oxyphylla Miq were determined using the fungus cake method and double dilution method. The seven Zingiberaceae plants exhibited characteristic antibacterial activities against pathogenic bacteria and fungi. At a… More >

Abstract Sugarcane bagasse was pyrolyzed using a laboratory fixed bed reactor to produce char and its by-product (pyrolysis liquid). The pyrolysis experiments were carried out using different temperatures (400°C and 500°C), heating rate (1 °C/min and 10 °C/min), and holding time (30 min and 60 min). Char was characterized according to its thermal properties, while the pyrolysis liquid was tested for its anti-fungal and anti-termite activities. Pyrolysis temperature and heating rate had a significant influence on the char properties and the yield of char and pyrolysis liquid, where a high-quality char and high yield of pyrolysis liquid can be obtained at… More >

Abstract We evaluated the in vitro antifungal activity of extracts of peruvian peppertree (Shinu smolle), cherimoya (Annona cherimola), cinnamon (Cinnamomum zeylanicum) and tobacco (Nicotiana glauca) on the mycelial growth and sporulation of Fusarium oxysporum, Fusarium culmorum and Fusarium solani. The research was conducted at the Universidad Autónoma de Aguascalientes (UAA) and the Universidad Autónoma Agraria Antonio Narro (UAAAN). The species of Fusarium were previously identified in the UAA Laboratory of Parasitology. The extracts were obtained in the laboratory of Toxicology of the UAAAN. The methodology of poisoned culture medium was used to determine the (1) inhibition of mycelial growth, (2) average… More >
