بالکینگ (یا حجیم شدن لجن)، شناور شدن توده های لجن، در اثر رشد بیش از اندازه باکتری های رشته ای و یا غیر رشته ای در فرآیند تصفیه پساب است که کاهش کیفیت فرآیند تصفیه و جریان خروجی را به دنبال دارد. با توجه به این که ازدیاد نوکاردیوفرم ها (nocardioforms) و beggiatoa به ترتیب نشانه وجود ترکیبات روغنی بالا و وجود گوگرد در سیستم است، با شناسایی باکتری های غالب بالکینگ کننده، می توان به عوامل ایجاد آن...
Bulking and foaming are two notorious problems in activated sludge wastewater treatment plants (WWTPs), which are mainly associated with the excessive growth of bulking and foaming bacteria (BFB). However, studies on affecting factors of BFB in full-scale WWTPs are still limited. In this study, data sets of high-throughput sequencing (HTS) of 16S V3-V4 amplicons of 58 monthly activated sludge s...
Despite differences in their morphologies, comparative analyses of 16S rRNA gene sequences revealed high levels of similarity (>94 %) between strains of the filamentous bacterium 'Candidatus Nostocoida limicola' and the cocci Tetrasphaera australiensis and Tetrasphaera japonica and the rod Tetrasphaera elongata, all isolated from activated sludge. These sequence data and their chemotaxonomic ch...
The ORF sequences of the gene encoding sepiapterin reductase were cloned from the genomic DNAs of Chlorobium tepidum and Chlorobium limicola, which are known to produce L-threo- and L-erythro-tetrahydrobiopterin (BH4)-N-acetylglucosamine, respectively. The deduced amino acid sequence of C. limicola consists of 241 residues, while C. tepidum SR has three residues more at the C-terminal. The over...
Sulfurifustis variabilis and Sulfuricaulis limicola are autotrophic sulfur-oxidizing bacteria belonging to the family Acidiferrobacteraceae in the order Acidiferrobacterales. The type strains of these species, strain skN76(T) and strain HA5(T), were isolated from lakes in Japan. Here we describe the complete genome sequences of Sulfurifustis variabilis skN76(T) and Sulfuricaulis limicola HA5(T)...
Göker, M. et al.Genome sequence of the mud-dwelling archaeon Methanoplanus limicola type strain (DSM 2279(T)), reclassification of Methanoplanus petrolearius as Methanolacinia petrolearia and emended descriptions of the genera Methanoplanus and Methanolacinia. Genome sequence of the mud-dwelling archaeon Methanoplanus limicola type strain (DSM 2279 T), reclassi-fication of Methanoplanus petrole...
The water mite Rutripalpus limicola Sokolow, 1934, can be considered exceptionally rare. It shows a scattered distribution range and, until recently, was known from six sites across Europe only. This strictly spring-dwelling species has highly localised distribution, presumably due to its specific ecological requirements. We present the first records of R. in Netherlands and review current stat...
The draft genome sequence of Chlorobium limicola strain Frasassi was assembled from metagenomic sequencing of a green mat in an artificially lighted aquarium inside the Frasassi caves in Italy. The genome is 2.08 Mbp in size and contains the necessary genes for anoxygenic photosynthesis and CO2 fixation.
A new taxonomy of the green sulfur bacteria is proposed, based on phylogenetic relationships determined using the sequences of the independent 16S rRNA and fmo (Fenna-Matthews-Olson protein) genes, and supported by the DNA G + C content and sequence signatures. Comparison of the traditional classification system for these bacteria with their phylogenetic relationship yielded a confusing picture...
We found that polyclonal antibodies raised against chlorosome polypeptides from green sulfur bacteria reacted to Chlorobium tepidum, Chlorobium limicola, and Chlorobium phaeobacteroides but not to Chloroflexus aurantiacus. These antibodies successfully labeled only green sulfur species in marine microbial mat samples. Our results suggest that these antibodies may be useful as immunohistochemica...
