摘要:
Four 10-membered ring resorcylic acid lactones (RALs) including a new compound hispidulactone F (1) and three known analogs hispidulactone B (2), 2 R, 4R-sonnerlactone (3), and 2 R, 4S-sonnerlactone (4) were isolated from the special bioenvironmental desert plant endophytic fungus Chaetosphaeronema hispidulum. The structure of the new compound hispidulactone F (1) was determined by extensive spectra analysis including HR-ESI-MS, NMR (1H, 13C, 1H-1H COSY, HSQC, and HMBC). Hispidulactone F (1) and hispidulactone B (2) were a pair of stereoisomers at C-3, whereas 2 R, 4R-sonnerlactone (3) and 2 R, 4S-sonnerlactone (4) were another pair of stereoisomers at C-4. The stereochemistries of the hydroxyl groups at C-3 in 1 and 2, and at C-4 in 3 and 4 were first determined by modified Mosher’s reactions. Thus, the absolute configuration C-3 in hispidulactone B (2) was not right in our previous report, and was rectified to be R. Compounds 1 and 4 were evaluated for their cytotoxic effects on the proliferation of HepG2. The possible biosynthetic pathway of compounds 1–4 was also presented. © 2020, The Author(s), under exclusive licence to the Japan Antibiotics Research Association.

摘要:
Streptococcus pneumoniae is a leading pathogen for bacterial pneumonia, which can be treated with bacteriophage lysins harboring a conserved choline binding module (CBM). Such lysins regularly function as choline-recognizing dimers. Previously, we reported a pneumococcus-specific lysin ClyJ comprising the binding domain from the putative endolysin gp20 from the Streptococcus phage SPSL1 and the CHAP (cysteine, histidine-dependent amidohydrolase/peptidase) catalytic domain from the PlyC lysin. A variant of ClyJ with a shortened linker, i.e., ClyJ-3, shows improved activity and reduced cytotoxicity. Resembling typical CBM-containing lysins, ClyJ-3 dimerized upon binding with choline. Herein, we further report a choline-recognizing variant of ClyJ-3, i.e., ClyJ-3m, constructed by deleting its C-terminal tail. Biochemical characterization showed that ClyJ-3m remains a monomer after it binds to choline yet exhibits improved bactericidal activity against multiple pneumococcal strains with different serotypes. In an S. pneumoniae-infected bacteremia model, a single intraperitoneal administration of 2.32 μg/mouse of ClyJ-3m showed 70% protection, while only 20% of mice survived in the group receiving an equal dose of ClyJ-3 (P < 0.05). A pharmacokinetic analysis following single intravenously doses of 0.29 and 1.16 mg/kg of ClyJ-3 or ClyJ-3m in BALB/c mice revealed that ClyJ-3m shows a similar half-life but less clearance and a greater area under curve than ClyJ-3. Taken together, the choline-recognizing monomer ClyJ-3m exhibited enhanced bactericidal activity and improved pharmacokinetic proprieties compared to those of its parental ClyJ-3 lysin. Our study also provides a new way for rational design and programmed engineering of lysins targeting S. pneumoniae. Copyright © 2020 American Society for Microbiology. All Rights Reserved.

摘要:
Black soldier fly larvae (BSFL), Hermetia illucens (Diptera: Stratiomyidae) can reduce environmental pollution and convert organic wastes into biomass that is rich in protein and fat. The influence of the nutritional characteristics of organic waste on BSFL characteristics relevant for food and feed safety remains poorly understood. To evaluate the conversion of soybean curd residues (SCR) into high-quality animal-derived proteins and fats for human and livestock consumption, this study assessed the co-conversion efficacy, nutrient composition, safety, and anti-nutritional factor concentrations in BSFL after the development on SCR with Lactobacillus buchneri (L3-9). SCR was pretreated with L. buchneri (10(8) cfu/ml), and then BSFL was employed for conversion. BSFL fed with SCR and L. buchneri had a significantly higher dry mass reduction (55.7+/-0.9%), bioconversion rate (6.9+/-0.3%), crude protein content (55.3+/-0.6%), and fat content (30.0+/-0.6%) than SCR (49.0+/-0.7%, 5.0+/-0.3%, 52.8+/-0.3%, and 26.1+/-0.8%, respectively) and artificial feed (43.9+/-0.8%, 3.9+/-0.1%, 50.3+/-0.4%, and 24.3+/-0.4%, respectively). However, the feed conversion ratio (8.0+/-0.3), of BSFL fed with SCR and L. buchneri was lower than that of the BSFL fed with SCR (9.8+/-0.1) and artificial feed (11.1+/-0.5). In addition, BSFL had satisfactory concentrations of all essential amino acids and fatty acids required for human consumption as recommended by WHO/FAO/UNU. The heavy metals and anti-nutritional factor concentrations were within the safety intake levels for food and feedstock. Therefore, the addition of L. buchneri with BSFL on SCR did not only increase co-conversion performance but also enhanced the nutritional value of BSFL.

5-hydroxymethylcytosine;hydroxymethylase;(H2O)-O-18 feeding;mildiomycin
摘要:
5-Hydroxymethylcytosine (5hmC) was present in T-even phage and mammalian DNA. 5hmC in phage is formed by hydroxymethylation of the cytosine base in deoxycytidylate (dCMP) by deoxycytidylate hydroxymethylase (CH), which uses the solvent water as the hydroxyl group donor. By contrast, 5hmC is formed in mammal zygotes by the oxidation of 5-methylcytosine (5mC). 5hmC was also present in a nucleoside antibiotic mildiomycin and its formation is governed by a cytidylate hydroxymethylase MilA. However, the catalytic mechanism remains unknown. In the present study, we purified His-tagged MilA and fed its in vitro reaction with H218O. The LC-MS analysis of the product revealed that 18O was incorporated into the hydroxymethylated CMP (HmCMP), and the secondary MS result of 18O-labeled HmCMP indicated that 18O was incorporated into the cytosine of HmCMP. The results demonstrate that MilA uses solvent water as the hydroxyl group donor like CH. Moreover, Thr102 of MilA was predicted as potential critical amino acid anchoring one molecule of water for hydroxylation. Finally, organizational context comparison in microbial genomes reveals that six homologous ORFs originally annotated as putative thymidylate synthase (TS) are more likely to be CMP hydroxymethylase. © 2013 The Author(s).

摘要:
Listeria monocytogenes is a food-borne bacterial pathogen and the causative agent of human and animal listeriosis. Among the three major genetic lineages of L. monocytogenes (i.e., LI, LII, and LIII), LI and LII are predominantly associated with food-borne listeriosis outbreaks, whereas LIII is rarely implicated in human infections. In a previous study, we identified a Crp/Fnr family transcription factor gene, lmo0753, that was highly specific to outbreak-associated LI and LII but absent from LIII. Lmo0753 shares two conserved functional domains, including a DNA binding domain, with the well-characterized master virulence regulator PrfA in L. monocytogenes. In this study, we constructed lmo0753 deletion and complementation mutants in two fully sequenced L. monocytogenes LII strains, 10403S and EGDe, and compared the flagellar motility, phospholipase C production, hemolysis, and intracellular growth of the mutants and their respective wild types. Our results suggested that lmo0753 plays a role in hemolytic activity in both EGDe and 10403S. More interestingly, we found that deletion of lmo0753 led to the loss of L-rhamnose utilization in EGDe, but not in 10403S. RNA-seq analysis of EGDe δ0753 incubated in phenol red medium containing L-rhamnose as the sole carbon source revealed that 126 (4.5%) and 546 (19.5%) out of 2,798 genes in the EGDe genome were up- and downregulated more than 2-fold, respectively, compared to the wild-type strain. Genes related to biotin biosynthesis, general stress response, and rhamnose metabolism were shown to be differentially regulated. Findings from this study collectively suggested varied functional roles of lmo0753 in different LII L. monocytogenes strain backgrounds associated with human listeriosis outbreaks. ©2013, American Society for Microbiology.

摘要:
The thiol-functionalized eggshell membrane (TF-ESM) was prepared by esterification between thioglycolic acid (CH2SHCOOH) and oxygen-containing functional groups on eggshell membrane (ESM). A promising potential biosorbent, TF-ESM, was used for the removal of toxic mercury in wastewater. Aqueous of mercury ions removing properties by TF-ESM were studied through batch experiments. The results indicated that the modified ESM has greatly enhanced the adsorption capacity for Hg2+, the maximum capacity was increased more than 3-fold in comparison with the unmodified ESM, from 19.4 mg g-1 to 71.9 mg g-1. The optimum of pH value for Hg adsorption was in the range of 2-8, which the removing rate over 96%. The results obtained show that the novel thiol-functionalized eggshell membrane performed well the removal and recovery of mercury from low concentration wastewaters. © (2010) Trans Tech Publications, Switzerland.

摘要:
A marine Streptomyces sp. 060524 capable of hydrolyzing the glycosidic bond of isoflavone glycosides, was isolated by detecting its β-glucosidase activity. 5 isoflavone aglycones were isolated from culture filtrates in soybean meal glucose medium. They were identified as genistein (1), glycitein (2), daidzein (3), 3′,4′,5,7-tetrahydroxyisoflavone (4), and 3′,4′,7-trihydroxyisoflavone (5), based on UV, NMR and mass spectral analysis. The Streptomyces can selectively hydroxylate at the 3′-position in the daidzein and genistein to generate 3′-hydroxydaidzein and 3′-hydroxygenistein, respectively. The Strain biotransformed more than 90% of soybean isoflavone glycosides into their aglycones within 108 h. 3′-hydroxydaidzein and 3′-hydroxygenistein exhibited stronger cytotoxicity against K562 human chronic leukemia than daidzein and genistein.
