概括
人类在水道中的污水是令人担忧的. 研究人员发现,像乙氨基和甲胺这样的化学标记物提供了比城市流中的微生物标记物更高,更一致的污水污染估计.
科学领域:
- 环境科学 环境科学
- 水质监测 水质监测
- 微生物学和化学
背景情况:
- 人类的污水污染了水体的营养物质,病原体和化学物质.
- 评估水质依赖于各种污水指标,但其有效性各不相同.
- 了解污水污染对人类和生态健康至关重要.
研究的目的:
- 测量和比较多种微生物和化学标记物用于检测人类污水的有效性.
- 评估城市河流污染污水的时间模式.
- 根据污水标记,比较Underwood Creek和Menomonee河的污染水平.
主要方法:
- 在两年内,每两周从密尔沃基的两个城市溪流收集水样.
- 从当地的水资源回收设施每月收集污水流量样本.
- 测量了21种微生物和106种化学标记物的发生和度.
- 人类污水的估计比例使用五个关键指标 (胡轻斑病毒,人类Bacteroides,人类Lachnospiraceae,乙氨基,甲胺) 的平均流量和流量度.
主要成果:
- 大多数标记物没有足够的灵敏度来检测污水污染.
- 化学标记物 (乙氨基,甲胺) 与彼此相关,并产生了比微生物标记物更高的污水污染估计值.
- 微生物标记物显示出更大的时间变化.
- 五个标记中有四个表明Underwood Creek的污水污染比Menomonee河污染少一个数量级.
结论:
- 化学标记物如乙氨基和甲胺在估计污水污染时比微生物标记物更可靠,因为它们的时间变化较小.
- 不同的标记物提供了由于运输,减弱和降解过程而导致的污水污染的不同估计值.
- 在监测和研究中,利用多种证据线 (各种标记) 对于强大的污水污染特征是必不可少的.

Methods to Assess Microbial Populations
Assessing microbial populations is crucial for understanding microbial roles in health, ecology, and industry. Various complementary techniques—both culture-based and molecular—enable detailed analysis of microbial abundance, diversity, and function.Viable Plate CountThe viable plate count is a traditional culture-based method used to estimate the number of living microbes in a sample. After serial dilution, the sample is spread onto nutrient agar plates. Each viable cell forms a visible...
Automated Microbial Diagnostics
Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
