Abstract
Kluyveromyces marxianus is an ascomycetous yeast which has shown promising results in cellulosic ethanol and renewable chemicals production. It can survive on a variety of carbon sources under industrially favorable conditions due to its fast growth rate, thermotolerance, and acid tolerance. K. marxianus, is generally regarded as a safe (GRAS) microorganism, is widely recognized as a powerhouse for the production of heterologous proteins and is accepted by the US Food and Drug Administration (USFDA) for its pharmaceutical and food applications. Since lignocellulosic hydrolysates are comprised of diverse monomeric sugars, oligosaccharides and potential metabolism inhibiting compounds, this microorganism can play a pivotal role as it can grow on lignocellulosic hydrolysates coping with vegetal cell wall derived inhibitors. Furthermore, advancements in synthetic biology, for example CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats with Cas9)-mediated genome editing, will enable development of an engineered yeast for the production of biochemicals and biopharmaceuticals having a myriad of industrial applications. Genetic engineering companies such as Cargill, Ginkgo Bioworks, DuPont, Global Yeast, Genomatica, and several others are actively working to develop designer yeasts. Given the important traits and properties of K. marxianus, these companies may find it to be a suitable biocatalyst for renewable chemicals and fuel production on the large scale. This paper reviews the recent progress made with K. marxianus biotechnology for sustainable production of ethanol, and other products utilizing lignocellulosic sugars.

Abstract
Zygosaccharomyces rouxii produces high levels of 4-hydroxy-2,5-dimethyl-3(2H)-furanone in YPD medium supplemented with 120 g/L D-fructose and 180 g/L NaCl after 5 d. D-fructose has a stress effect on Z. rouxii, and GSH-Px is a main enzyme involved in the defense of Z. rouxii against oxygen stress according to our previous report. In order to further explore the molecular mechanism of the glutathione metabolism pathway in Z. rouxii in response to D-fructose stress, changes in the expression of genes and proteins involved in the synthesis of glutathione precursor amino acids and enzymes were observed. In addition, changes in the intermediates related to glutathione synthesis in Z. rouxii were reported. The results indicated that some gene-encoding enzymes involved in the glutamate, cysteine and glycine biosynthesis pathways and key genes involved in glutathione synthesis were upregulated. The expression levels of other genes, except SHMT, were consistent with the qRT-PCR results. The contents of γ-glutamylcysteine and glutathione amide in the D-fructose group were higher than those in the control group. In the D-fructose stress groups, the metabolic flux towards glutathione synthesis was increased. These results might provide more in-depth and detailed theoretical support for the oxidative stress defense mechanism of Z. rouxii under D-fructose stress.

Abstract
Chestnut rose (Rosa roxburghii Tratt.) is a native fruit in China, rich in bioactive compounds. Chemical properties and bioactive compounds in the largest two cultivars (Gui Nong No. 5 and Golden Cili) of chestnut rose from different regions were analyzed and compared. Meanwhile, catechin, quercetin, myricetin, kaempferol, ellagic acid and ellagic acid glucuronide were identified. By comparison, Guinong No. 5 showed higher SOD actitviy (5,687.67-5,797.48 U/g), ascorbic acid (1.38-1.47 g/100 g), catechin (971.67-1405.75 mg/100 g) and myricetin (851.32-876.32 mg/100 g), antioxidant capacity, while Golden Cili was characterized with higher total flavnoids (263.30-278.63 mg/100 g), β-carotene (747.31-859.21 μg/100 g) and zeaxanthin (186.03-268.78 μg/100 g), glucose (10.32-12.03 g/100 g) and arabinose (3.22-3.43 g/100 g), tartaric acid (0.20-0.52 g/100 g), quercetin (1,034.63-1,411.08 mg/100 g). The principal components analysis method can be used to separate two cultivars well and partial least squares discrimination analysis method can be used to distinguish different planting regions well.

Abstract
Superoxide dismutases (SODs) were purified from sea buckthorn and chestnut rose by ammonium sulfate precipitation and anion-exchange chromatography, and the detection methods of water-soluble tetrazolium-1 (WST-1), nitrobluetetrazolium (NBT) and pyrogallol autoxidation (PA) for SOD activity were compared. WST-1 method was selected due to its coefficient of variation (CV) <6% in this study. Two SODs exhibited similar characteristics. Their molecular mass and isoelectric point were about 30 kDa and 4.8 to 5.0 estimated by electrophoresis, and the Km was 0.05 to 0.08 mmol/L, respectively. Dynamic light scattering analysis suggested their hydrodynamic radius distributes from 60 to 1500 nm. The activity of two SODs was unchanged at <80 °C or pH 2 to 9 or in simulated human gastric fluid. Their circular dichroism spectra suggested a main β-sheet structure, the fluorescence spectra reflected that the tryptophan residues of two SODs is partially exposed, these structures were rather stable at pH 2 to 9 or 50 to 90 °C. PRACTICAL APPLICATION: Superoxide dismutase (SOD) is an important antioxidant enzyme. SODs from sea buckthorn and chestnut rose were stable at high temperature or low pH or simulated gastric fluid. This result can provide a new approach for the potential application of SOD in the food and pharmaceutical fields.

Abstract
BACKGROUND CuZn-Superoxide dismutase (SOD) is a unique enzyme, which can catalyzes the dismutation of inevitable metabolic product i.e.; superoxide anion into molecular oxygen and hydrogen peroxide. The enzyme has gained wide interest in pharmaceutical industries due to its highly acclaimed antioxidative properties. The recombinant expression of this protein in its enzymatically active and stable form is highly desired and hence optimization of culture conditions and characterization of the related biochemical properties are essential to explore the significance of the enzyme in physiological, therapeutic, structural and transgenic research. RESULTS High-level expression of the chloroplastic isoform of Pisum sativum CuZn-SOD was achieved at 18°C, upon isopropyl β-D-1-thiogalactopyranoside induction and the process was optimized for maximum recovery of the protein in its soluble (enzymatically active) form. Both crude and purified protein fractions display significant increase in activity following supplementation of defined concentration Cu (CuSO4) and Zn (ZnSO4). Yield of the purified recombinant protein was ~ 4 mg L(-1) of culture volume and the bacterial biomass was ~ 4.5 g L(-1). The recombinant pea chloroplastic SOD was found to possess nearly 6 fold higher superoxide dismutase activity and the peroxidase activity was also 5 fold higher as compared to commercially available CuZn-superoxide dismutase. The computational, spectroscopic and biochemical characterization reveals that the protein harbors all the characteristics features of this class of enzyme. The enzyme was found to be exceptionally stable as evident from pH and temperature incubation studies and maintenance of SOD activity upon prolonged storage. CONCLUSIONS Overexpression and purification strategy presented here describes an efficient protocol for the production of a highly active and stable CuZn-superoxide dismutase in its recombinant form in E. coli system. The strategy can be utilized for the large-scale preparation of active CuZn-superoxide dismutase and thus it has wide application in pharmaceutical industries and also for elucidating the potential of this protein endowed with exceptional stability and activity.

Abstract
Superoxide dismutase (SOD; EC 1.15.1.1) is an antioxidant enzyme that represents the primary cellular defense against superoxide radicals and has interesting applications in the medical and cosmetic industries. In the present work, the partition behavior of SOD in aqueous two-phase systems (ATPS) (using a standard solution and a complex extract from Kluyveromyces marxianus as sample) was characterized on different types of ATPS (polymer-polymer, polymer-salt, alcohol-salt, and ionic liquid (IL)-salt). The systems composed of PEG 3350-potassium phosphate, 45% TLL, 0.5 M NaCl (315 U/mg, 87% recovery, and 15.1-fold purification) and t-butanol-20% ammonium sulfate (205.8 U/mg, 80% recovery and 9.8-fold purification), coupled with a subsequent 100 kDa ultrafiltration stage, allowed the design of a prototype process for the recovery and partial purification of the product of interest. The findings reported herein demonstrate the potential of PEG-salt ATPS for the potential recovery of SOD.

Abstract
Three superoxide dismutases (EC 1.15.1.1) (TLSOD1, TLSOD2 and TLSOD3) were purified from larvae of the camel tick Hyalomma dromedarii by ammonium sulfate precipitation, ion exchange and gel filtration columns. SDS-PAGE revealed that the subunit molecular masses of the SODs are 40±2 kDa, 67±1.5 kDa and 45±2.6 kDa for TLSOD1, TLSOD2 and TLSOD3, respectively. TLSOD1 and TLSOD2 are monomeric proteins, while TLSOD3 isoenzyme exhibits dimeric structure with native molecular mass of 90 kDa. The pI values are estimated at pH 8.0, pH 7.2 and pH 6.6 for the three SODs which displayed pH optima at 7.6, 8.0 and 7.8, respectively. CuCl(2) and ZnCl(2) increase the activity of TLSOD2 and TLSOD3, while MnCl(2) increases the activity of TLSOD1. KCN inhibits the activity of TLSOD2 and TLSOD3, while a remarkable resistance of TLSOD1 isoenzyme was detected. TLSOD1 is suggested to be a manganese containing isoenzyme while TLSOD2 and TLSOD3 are suggested to be copper/zinc-containing isoenzymes. These results indicate the presence of three different forms of SODs in the larval stage of camel tick. This finding will contribute to our understanding of the physiology of these ectoparasites and the development of non-traditional methods to control them.

Abstract
The native form of Cu/Zn-superoxide dismutase, isolated from fungal strain Humicola lutea 103 is a homodimer that coordinates one Cu(2+) and one Zn(2+) per monomer. Cu(2+) and Zn(2+) ions play crucial roles in enzyme activity and structural stability, respectively. It was established that HLSOD shows high pH and temperature stability. Thermostability of the glycosylated enzyme Cu/Zn-SOD, isolated from fungal strain H. lutea 103, was determined by CD spectroscopy. Determination of reversibility toward thermal denaturation for HLSOD allowed several thermodynamic parameters to be calculated. In this communication we report the conditions under which reversible denaturation of HLSOD exists. The narrow range over which the system is reversible has been determined using the strongest test of two important thermodynamic independent variables (T and pH). Combining both these variables, the "phase diagram" was determined, as a result of which the real thermodynamic parameters (ΔC(p), ΔH(exp)°, and ΔG(exp)°) was established. Because very narrow pH-interval of transitions we assume they are as result of overlapping of two simple transitions. It was found that ΔH(o) is independent from pH with a value of 1.3 kcal/mol and 2.8 kcal/mol for the first and the second transition, respectively. ΔG(o) was pH-dependent in all studied pH-interval. This means that the transitions are entropically driven, these. Based on this, these processes can be described as hydrophobic rearrangement of the quaternary structure. It was also found that glycosylation does not influence the stability of the enzyme because the carbohydrate chain is exposed on the surface of the molecule.

Abstract
Here, we present further characterization of cryptococcal CUF1 in copper homeostasis. We demonstrated that CUF1 was involved both in copper acquisition and in copper detoxification in response to copper variation. This was verified by direct measurement of the quantity of intracellular copper with flame atomic absorption spectrometry (FAAS) and molecular evidence. In copper-limited growth, the mutant cuf1Δ exhibited copper deficiency, growth defect on glycerol and sensitivity to hydrogen peroxide and methionine. A novel function of cryptococcal CUF1 is revealed in copper detoxification when copper is in excess. The mutant cuf1Δ showed severe hypersensitivity to exogenous copper, while a high level of copper was accumulated shown by FAAS, suggesting that CUF1 may be required in copper export events. On cloning of cDNA, it was found that Cuf1 distinguishably harbors functional elements that are found in Ace1 and Mac1 of Saccharomyces cerevisiae. The regulation of copper homeostasis by Cuf1 is realized by its subcellular localization. Epifluorescence microscopy observed that, upon copper depletion, Cuf1 was localized exclusively to the nucleus as an activator for CTR4 transcription, while it was located to the cell periphery in the presence of exogenous copper. This work reveals a unique copper regulator and may provide insights into the copper metabolism in fungi.
