Abstract 5’-Nucleotidases (EC 3.1.3.5) are enzymes that catalyze the hydrolytic dephosphorylation of 5′-ribonucleotides and 5′-deoxyribonucleotides to their corresponding nucleosides plus phosphate. In the present study, to search for new genes encoding 5′-nucleotidases specific for purine nucleotides in industrially important Bacillus species, “shotgun” cloning and the direct selection of recombinant clones grown in purine nucleosides at inhibitory concentrations were performed...

Abstract Alcohol dehydrogenases (ADHs) catalyze the reversible reduction of a carbonyl group to its corresponding alcohol. ADHs are widely employed for organic synthesis due to their lack of harm to the environment, broad substrate acceptance, and high enantioselectivity. This review focuses on the impact and relevance of ADH enantioselectivities on their biotechnological application. Stereoselective ADHs are beneficial to reduce challenging ketones such as ketones owning two...

Abstract The extremophile red alga Galdieria sulphuraria was successfully grown immobilized in a twin-layer porous substrate bioreactor (TL-PSBR). A maximal biomass growth rate of 10 g dry weight m−2 day−1 was measured at a photon fluence rate of 200 μmol photons m−2 s−1 with addition of 1% CO2 and a temperature of 34 °C. Under these conditions, a maximal biomass value of 232 g m−2 was attained after 33 days of growth. Phycobilin productivity, however, was highest at a lower...

Abstract Nitrate accumulation causes long-time threat to aquatic animals in recirculating aquaculture system (RAS); thus, nitrate removal is also required in RASs. However, the lack of carbon sources makes denitrification difficult to function. Nitrate removal performance of an aerobic denitrifying and extracellular polyhydroxyalkanoate depolymerase–producing bacterium, Pseudomonas sp. AOB-7, using polyhydroxyalkanoate (PHA) granules as a solid sustained-release...

Abstract In the present work, we used systematic engineering at transport and transcription levels to significantly enhance alkaline α-amylase production in Bacillus subtilis 168M. Signal peptide YwbN’ proved to be optimal. Alkaline α-amylase production was elevated by deleting a putative peptide segment of YwbN’. Insertion of arginine (R) between residues 5 and 6 of YwbN’∆p further increased the protein yield. Enhancing positive charges at sites 4 and 10 and decreasing the...

Abstract Agar, a major component of the cell wall of red algae, is an interesting heteropolysaccharide containing an unusual sugar, 3,6-anhydro-l-galactose. It is widely used as a valuable material in various industrial and experimental applications due to its characteristic gelling and stabilizing properties. Agar-derived oligosaccharides or mono-sugars produced by various agarases have become a promising subject for research owing to their unique biological activities, including...

Abstract Monascus is a filamentous fungus that produces several secondary metabolites. Here, we investigated the effects of the global regulator LaeA on the synthesis of pigments and monacolin K in Monascus purpureus with spectrophotometer and HPLC methods. The LaeA gene was isolated from M. purpureus M1 to create an overexpression construct. An LaeA-overexpressing strain L3 was with 48.6% higher monacolin K production than the M1 strain. The L3 strain also produced higher Monascus...

Abstract Metarhizium species are the most abundant fungi that can be isolated from soil, with a well-known biopesticide capacity. Metarhizium recognizes their hosts when the conidium interacts with insects, where the fungi are in contact with the hydrocarbons of the outermost lipid layer cuticle. These cuticular hydrocarbons comprise a mixture of n-alkanes, n-alkenes, and methyl-branched chains. Metarhizium can degrade insect hydrocarbons and use these hydrocarbons for energy...

Abstract Malachite green is a carcinogenic dye that has been detected in fish tissues and freshwater. Here we evaluated the malachite green decoloring ability of a photoautotrophic cyanobacterium, Synechococcus elongatus PCC 7942 (Synechococcus), that lives in freshwater. Results show that 99.5% of the dye was removed by Synechococcus through bioabsorption and bioaccumulation; however, the dye was not degraded or chemically modified. Next, we established an engineered Synechococcus...

We present a case of perilymphatic fistula (PLF) with inner ear anomalies having sudden, progressive sensorineural hearing loss and describe the fistula repair surgeries. We focus on the diagnosis methods of PLF and clinical course of PLF with inner ear anomaly. The cochlin-tomoprotein (CTP) detection test is very useful for the surgeons to encourage the earlier operation to sudden hearing loss cases. It is also helpful to define the diagnosis of PLF after operation. We could not get the good result...

Background and Objectives Fluorescence‐guided resection of glioblastomas (GBM) using 5‐aminolevulinic acid (5‐ALA) improves intraoperative tumor visualization and is thus widely used nowadays. During resection, different fluorescence levels can usually be distinguished within the same tumor. Recently, we demonstrated that strong, vague, and no fluorescence correspond to distinct histopathological characteristics in newly diagnosed GBM. However, the qualitative fluorescence classification by the...

Background and Objectives Radiofrequency (RF)‐induced ablation can be carried out inside ducts and vessels by simultaneously dragging a bipolar catheter while applying RF power. Our objective was to characterize the relation between pullback speed, impedance progress, and temperature distribution. Study Design/Materials and Methods We built a numerical model including a bipolar catheter, which is dragged inside a duct while RF power is applied between a pair of electrodes. The model solved...
