Anthropogenic activities release effluents containing nutrients and pathogenic bacteria that change the characteristics of coastal ecosystems. An important type of marine pollution which has occurred in 3 different states in India during 2019 is sea foam. Sea foam was found on Hole beach, Goa (Lat: 15.404° N, Long: 73.787° E), where nutrients (NO₃⁻ = 137 μM and organic nitrogen = 121 μM) from a garbage dumpyard are released directly via streams/gutters to coastal waters. This resulted in a bloom of the diatom Thalassiosira pseudonana, associated with high concentration of total organic carbon and fucoxanthin. Decay of this bloom along with strong agitation due to rocks and wave action resulted in sea foam. We isolated foam-associated bacteria and identified pathogenic bacteria including Enterobacter cancerogenus through 16S rRNA gene sequencing. Such foam-associated pathogenic bacteria, could be antibiotic resistant, and may have adverse effects on human health. This can also hamper the tourism industry of a small state like Goa that relies heavily on tourism.

人为活动释放出含有营养物质和致病菌的废水，这些废水改变了沿海生态系统的特征。海洋泡沫是2019年在印度三个不同州发生的一种重要海洋污染类型。海泡沫上孔海滩发现，果阿（纬度：15.404°N，长：73.787°E），其中，营养物质（NO ₃ ^-从垃圾dumpyard = 137μM和有机氮= 121μM）经由流/排水沟直接释放到沿海水域。这导致硅藻Thalassiosira pseudonana盛开，与高浓度的总有机碳和岩藻黄质有关。由于岩石和波浪作用，这种水华的衰落以及强烈的搅动导致了海泡。我们分离了泡沫相关细菌，并通过16S rRNA基因测序鉴定了包括致癌肠杆菌在内的致病细菌。这种泡沫相关的致病细菌可能具有抗生素抗性，并且可能对人体健康产生不利影响。这也可能妨碍像果阿这样的小国的旅游业，该国高度依赖旅游业。
