Biofilms of a municipal water distribution system were characterized to assess the occurrence of fungi within surface matrixes. Densities of filamentous fungi ranged from 4.0 to 25.2 CFU cm(-2), whereas yeast densities ranged from 0 to 8.9 CFU cm(-2). Observations by scanning electron microscopy further suggested that spores, not hyphae or vegetative cells, comprised the primary source of viable propagules.
对一个城市供水系统中的生物膜进行了表征,以评估表面基质中真菌的存在情况。丝状真菌的密度范围为4.0至25.2 CFU cm(-2),而酵母的密度范围为0至8.9 CFU cm(-2)。扫描电子显微镜观察进一步表明,孢子而非菌丝或营养细胞是活繁殖体的主要来源。
