A bioflocculant-producing marine bacterium previously isolated from marine sediment of Algoa Bay was screened for flocculant production. Comparative analysis of 16S rDNA sequence identified the isolate to have 99% similarity to Virgibacillus sp. XQ-1 and it was deposited in the GenBank as Virgibacillus sp. Rob with accession number HQ537127. The bacterium produced biflocculants optimally in glucose (70.4%) and peptone (70.4%) as sole sources of carbon and nitrogen, alkaline pH (12) (74%); and the presence of Fe2+ (74%). Chemical analysis of the bioflocculant revealed it to be a polysaccharide.
从阿尔戈阿湾海洋沉积物中分离到的一种产生物絮凝剂的海洋细菌被筛选用于絮凝剂生产。16S rDNA 序列的比较分析表明，该分离株与 Virgibacillus sp. XQ-1 的相似度为 99%，并在 GenBank 中作为 Virgibacillus sp. Rob 进行了登记， accession number HQ537127。该细菌在葡萄糖（70.4%）和蛋白胨（70.4%）作为唯一的碳源和氮源、碱性 pH（12）（74%）和 Fe2+（74%）存在的条件下最佳地产生双絮凝剂。生物絮凝剂的化学分析表明它是一种多糖。
