The objective of this study was to examine the alkalithermophilic actinomycete communities in the subtropical environment of Jujuy, Argentina, characterized by sugarcane crops. Laceyella putida, Laceyella sacchari, Thermoactinomyces intermedius, Thermoactinomyces vulgaris and Thermoflavimicrobium dichotomicum were isolated on the media with novobiocin, from sugar cane plants and renewal rhizospheres, and grass and wood soils. Soil pH was almost neutral or lightly alkaline, except for grass soil acidified by lactic liquor. A smaller number of actinomycetes was found on the living plants and bagasse (recently obtained or stored according to the Ritter method) with respect to decomposed leaves on the soil. Thermophilic species of Laceyella, Thermoactinomyces, Thermoflavimicrobium, Saccharomonospora, Streptomyces and Thermononospora were isolated on the media without novobiocin, from composted sugar cane residues. Air captured near composted bagasse piles, contained alkalithermophilic actinomycete spores.
本研究的目的是调查阿根廷胡胡伊亚热带环境中以甘蔗作物为特征的嗜碱嗜热放线菌群落。在含有新生霉素的培养基上，从甘蔗植株、更新根际以及草地和林地土壤中分离出了恶臭拉西放线菌、嗜糖拉西放线菌、中间嗜热放线菌、普通嗜热放线菌和双歧嗜热黄微菌。土壤pH值几乎呈中性或轻度碱性，但被乳酸液酸化的草地土壤除外。与土壤上的落叶相比，在活植物和蔗渣（根据里特方法最近获取或储存的）上发现的放线菌数量较少。在不含新生霉素的培养基上，从堆肥甘蔗残渣中分离出了嗜热的拉西放线菌属、嗜热放线菌属、嗜热黄微菌属、糖单孢菌属、链霉菌属和嗜热无孢菌属的菌种。在堆肥蔗渣堆附近捕获的空气中含有嗜碱嗜热放线菌孢子。
