Soils are generally considered a complex and largely unexplored vital “black box” with thousands of microorganism taxa in their networks [...]

We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of micr...

In this paper, we propose a novel high-speed microrobotic system toward swimming-microorganism capturing and sensing in a microfluidic chip. This system consists of high-speed on-chip microrobots as robotic hands with a maximum speed of 10 Hz to handle a microorganism and a high-speed on-line vision sensor as a robotic eye with maximum speed of 2000 frames/s to track the trajectory of microorga...

The small scale industries located at Mira Road, Mumbai, are engaged in various processes/operations which generate the wastes. The waste generated are collected and disposed of at the dumping ground near the industrial estate. In the present study, the physico-chemical and microbial status of the contaminated sites has been carried out. The heavy metal with special reference to copper was expo...

A novel application of whole cells of Nocardia corallina B-276 for the deracemisation of ibuprofen is reported. This microorganism successfully hydrolysed ibuprofen nitrile to ibuprofen amide, and ibuprofen amide to ibuprofen, using a suspension of cells in a potassium phosphate buffer solution (0.1 M, pH = 7.0). These results can be explained by the presence of NHase and amidase enzymes, but t...

Trichoderma reesei can be considered as a candidate for consolidated bioprocessing (CBP) microorganism. However, its ethanol yield needs to be improved significantly. Here the ethanol production of T. reesei CICC 40360 was improved by genome shuffling while simultaneously enhancing the ethanol resistance. The initial mutant population was generated by nitrosoguanidine treatment of the spores, a...

Streptococcus constellatus is a microorganism that lives commensally in the oropharyngeal region, urogenital region, and intestinal tract. However, it can cause infection in patients with certain predisposing factors. Rarely, this microorganism can cause a brain abscess. Thalamic localization of brain abscesses is much rarer than abscesses in other locations of the brain. Brain abscess caused b...

The present work aims to evaluate filamentous bulking control in hybrid systems. For this study, four sequencing batch reactors (SBR) fed with acetate were operated without (SBR1) and with support for biofilm growth [5 % (SBR2), 10 % (SBR3) and 20 % (SBR4) of the reactor volume]. The results demonstrated an overabundance of a filamentous fungi-like microorganism in the SBR operating just with s...

Tetrodotoxin (TTX), is a potent neurotoxin found in genetically diversed organisms. Many TTX producing microorganism have also been isolated from TTX bearing animals. The TTX producing microbes found in four different phylum (Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes), the Proteobacteria are the dominating one. In most of the cases, TTX producing microbes are found in the int...

In this study, a full-scale membrane bioreactor (MBR) was monitored over a period exceeding 6 months. Two common chemical cleaning modes, chemically enhanced backwash and clean in place, with sodium hypochlorite were monitored with respect to microorganism log removal value (LRV). Overall, impact to microorganism LRV for virus, bacteria and protozoa due to cleaning was negligible with respect t...
