A new species was isolated from the largest of the San Antonio Springs, the Blue Hole, in San Antonio, Texas, and characterized for its potential applications in sustainable agriculture. The xenic isolate () was established by enrichment and subcultured to produce the axenic isolate (), which was identified based on morphological features and DNA profiling, confirming its close phylogenetic relationship with spp. Growth characteristics, biomass composition, and pigment profiles were assessed for both the xenic and axenic isolates along with their growth in saline conditions and a range of seasonal Texas temperatures. Both and exhibited optimal growth at 25 °C as well as robust growth at 37 °C and in weakly saline media (5 g/kg NaCl). Biomass analysis revealed levels of carbohydrates, proteins, lipids, chlorophylls, and carotenoids comparable to other desmids and pigment profiles supported the classification. Soil studies demonstrated the persistence of and influence on microbial activity, indicating the potential of this isolate for agricultural applications such as soil remediation.
从得克萨斯州圣安东尼奥市最大的圣安东尼奥泉——蓝洞中分离出一个新物种，并对其在可持续农业中的潜在应用进行了表征。通过富集建立了混合培养物分离株（），并进行传代培养以产生无菌分离株（），根据形态特征和DNA分析对其进行鉴定，证实其与 属物种有密切的系统发育关系。评估了混合培养物分离株和无菌分离株的生长特性、生物量组成和色素谱，以及它们在盐渍条件和一系列得克萨斯州季节性温度下的生长情况。 和 在25°C时均表现出最佳生长，在37°C和弱盐培养基（5 g/kg NaCl）中也生长旺盛。生物量分析显示，碳水化合物、蛋白质、脂质、叶绿素和类胡萝卜素的含量与其他鼓藻类相当，色素谱支持了 的分类。土壤研究表明 的持久性及其对微生物活性的影响，表明该分离株在土壤修复等农业应用方面具有潜力。
