Increasing the resistance of plant-fermenting bacteria to lignocellulosic inhibitors is useful to understand microbial adaptation and to develop candidate strains for consolidated bioprocessing. Here, we study and improve inhibitor resistance in Clostridium phytofermentans (also called Lachnoclostridium phytofermentans), a model anaerobe that ferments lignocellulosic biomass. We survey the resi...

The Rhodococcus erythropolis (strain IGTS8) bacterium has a tremendous industrial interest as it can remove sulfur from crude oil through its four-enzyme (DszA-D) 4S metabolic pathway. DszC is one of the rate-limiting enzymes pathway and that most suffers feedback inhibition. We have combined molecular docking dynamics simulations to identify binding sites which two products pathway, 2-hydroxyb...

A robust cell envelope is the first line of defense in infectious pathogens when encountering host immune defenses. In Gram-positive bacteria, LytR-CpsA-Psr (LCP) family proteins play a major role synthesis and assembly envelope. The bacterium S. pyogenes causes wide range diseases from pharyngitis to septicemia, but involvement LytR wall this not clear. Therefore, we investigated whether pyoge...

Chlamydia pneumoniae, an intracellular Gram-negative respiratory bacterium, and macrophages are present in inflammatory tissue sites such as atherosclerotic lesions, where abnormal degradation of the extracellular matrix takes place. To evaluate the potential of C pneumoniae for participation in matrix destruction, we studied the effect of this bacterium on the production of 3 matrix-degrading ...

Staphylococcus aureus is one of the most common nosocomial sources of soft-tissue and skin infections and has more recently become prevalent in the community setting as well. Since the use of penicillins to combat S. aureus infections in the 1940s, the bacterium has been notorious for developing resistances to antibiotics, such as methicillin-resistant Staphylococcus aureus (MRSA). With the per...

The minimal bacteriostatic concentration of iodoacetate, azide, or proflavine was added at intervals during the latent periods of virus in three different bacterium-bacteriophage systems (M. aureus, B. mycoides, E. coli). For each interval at which inhibitor was added, the occurrence of lysis and the final yield of phage were determined. In the B. mycoides and E. coli systems, when added during...

background : to determine the role of letrozole, an aromatase inhibitor,in the treatment of endometriotic pain.   methods: in this prospective, randomized, controlled clinical trial in minimallyinvasive surgery research center,51 women with pelvic endometriosis and endometriotic pain (dyspareunia, dysmenorrhea, pelvic pain) score of 5 or more (for at least one of these endometriotic pain), afte...

angioedema is an asymmetric non-pitting oedema on face, lips, tongue and mucous membranes; any delay in diagnosis and treatment can be fatal. treatment with lisinopril as an angiotensin converting enzyme (ace) inhibitor, can be a reason of angioedema. here we report a case who developed oral-facial edema four years after using lisinopril/hydrochlorothiazide. laryngeal oedema is a main cause of ...

background sivelestat is a neutrophil elastase inhibitor (nei) with positive impact on the respiratory complications in thoracic surgery. based on the findings of a recent study, nei may have a good response for avoiding ischemia reperfusion injury in liver resection. conclusions intravenous nei administration had positive impact on the postoperative inflammatory response and oxygenation while ...

Substitution of critical residues in the alpha- and beta-subunit can turn the typically resistant ATP synthase from the bacterium Escherichia coli into an enzyme showing high sensitivity to the phytopathogenic inhibitor tentoxin, which usually affects only certain sensitive plant species. In contrast to recent results obtained with the thermophilic F(1) (Groth, G., Hisabori, T., Lill, H., and B...
