Foaming of activated sludge (AS) causes adverse impacts on wastewater treatment operation and hygiene. In this study, we investigated the microbial communities of foam, foaming AS and non-foaming AS in a sewage treatment plant via deep-sequencing of the taxonomic marker genes 16S rRNA and mycobacterial rpoB and a metagenomic approach. In addition to Actinobacteria, many genera (e.g., Clostridiu...

BACKGROUND Gordonia polyisoprenivorans is a ubiquitous aerobic actinomycetes bacterium that rarely cause infections in humans. Here, we report a case of G. polyisoprenivorans catheter-related bacteremia in an AIDS patient. CASE PRESENTATION A 37-year-old man with a past medical history of AIDS-related lymphoma suffered bacteremia caused by a Gram-positive corynebacterium. The strain was ident...

Gordonia jacobaea strain MV-1 is characterized by its ability to synthesize carotenoids (de Miguel et al., 2000). This bacterium belongs to the broad and diverse group of mycolic acid-containing actinomycetes, known as the mycolata group. Mycolata contains microorganisms of industrial interest such as Corynebacterium glutamicum, as well as others of clinical relevance such as Mycobacterium tube...

In the resent study, a diazotrophic bacterial isolate JPA2 having the ability to tolerate salinity (6 % NaCl) and plant growth-promoting features was isolated from rhizospheric soil of weed Chenopodium murale growing in saline soil of Pindara (EC 11.47 dS m-1), district Jind (Haryana). The nitrogen fixing ability of the isolate was confirmed by nifH gene amplification and acetylene reduction as...

Work on the nuclear cytology and life cycle of Nocardia corallina has previously been reported (Webb et al., 1954; Webb and Clark, 1957; Clark and Frady, 19.57). Extensive studies on the radiation response, physiology, and genetics of this organism have also been carried ouit in this laboratory. Throughout this work, one of the main problems involved in the experimental approach has been the el...

Introduction. Case reports have emerged with identification of Gordonia bronchialis infections including sternal wound infections and foreign bodies such as central lines and shunts. Case presentation. We present a case that demonstrates the need to consider Gordonia infection as a cause of sternal wound infection and highlights the utility of novel diagnostics to aid in the identification of u...
