Novel preparation of fungal conidiophores biomass as adsorbent for removal of phosphorus from aqueous solution. Environ Sci Pollut Res Int. 2020 Apr 04;: Authors: Kalaimurugan D, Durairaj K, Kumar AJ, Senthilkumar P, Venkatesan S Abstract The present study focused on phosphorus adsorption by novel fungal conidiophores biomass in aqueous solution. Fungal Conidiophores biomass was prepared from the fungal strains Aspergillus oryzae (YFK) and Fusarium oxysporum (YVS2). The functional groups and morphology of Conidiophores Biomass (CB) from these strains were characterized by FTIR and SEM. FTIR confirms the presence of alcohol, carboxylic acid, carbon dioxide, cyclic alkene, amine, alkene, fluoro compound, and halo compound groups. Batch mode study was carried out with two CB's such as Aspergillus oryzae CB (ACB) and Fusarium oxysporum CB (FCB) with initial concentration of phosphorus ranging from 20 to 100 mg L-1. Based on the batch experiments, the adsorption kinetics (pseudo first order and pseudo second order), isotherms (Freundlich and Langmuir models), and thermodynamic (standard entropy, energy, and enthalpy) parameters were calculated. The adsorption kinetics and isotherm studies showed that the adsorption data well fitted with PSO kinetic model. From the isotherm results, it was found that ACB and FCB exhibited highest adsorption capacity 25.64 mg g-1 and 26.32 mg g-1 of phosphorus respectively at the optimal condition ...

icz A Abstract The inhibiting activity of three yeast strains belonging to Pichia kudriavzevii, Pichia occidentalis, and Meyerozyma quilliermondii/Meyerozyma caribbica genera against common plant pathogens representing Mucor spp., Penicillium chrysogenum, Penicillium expansum, Aspergillus flavus, Fusarium cereals, Fusarium poae, as well as Botrytis cinerea genera was investigated. The yeast strains tested had a positive impact on growth inhibition of all target plant pathogens. The degree of inhibition was more than 50% and varied depending on both the yeast antagonist and the mold. Ethyl esters of medium-chain fa...

AbstractA new series of 1-(4-methyl-2-aryl-1,3-thiazol-5-yl)-2-(4-aryl-1,2,3-triazol-1-yl)ethanol (6a-t) have been synthesized by a click reaction of 2-azido-1-(4-methyl-2-phenylthiazol-5-yl)ethanone (3a-e) with substituted ethynylbenzene (4a-c) followed by reduction with sodiumboro hydride. The newly synthesized 1-(4-methyl-2-aryl-1,3-thiazol-5-yl)-2-(4-aryl-1,2,3-triazol-1-yl)ethanol derivatives were screened for in vitro antibacterial activityagainst a Gram negative strains,Escherichia coli (National Collection of Industrial Microorganisms, NCIM 2574), a Gram positive strainStaphylococcus albus (NCIM 2178) and in vitro ...

In this study, nanoparticles were obtained by using poly-(ε-caprolactone), a polyester chosen for its biocompatibility and biodegradability properties. Poly-(ε-caprolactone) nanoparticles were formulated by using poly(vinyl alcohol) or Pluronic® F127 as non-ionic surfactants, and then loaded with benzophenone or valerophenone thiosemicarbazone, two compounds that inhibit aflatoxin production by Aspergillus flavus. The different types of nanoparticles were compared in terms of size, polydispersity index, morphology, and drug loading capacity. Finally, their effects were investigated on growth, developmen...

In this study, we identified 51 carbohydrate hydrolyses in the baijiu fermentation by metaproteomics analysis. Through source tracking analysis, approximately 80% of carbohydrate hydrolyses in the baijiu fermentation were provided by Jiuqu Among these enzymes, alpha-amylase (EC 3.2.1.1) and glucoamylase (EC 3.2.1.3), from Aspergillus, Rhizomucor and Rhizopus, were positively related to starch hydrolysis and ethanol production, indicating that they were the key saccharifying enzymes associated with alcoholic fermentation in the baijiu fermentation. Moreover, a combined mixture of alpha-amylase and glucoamylase (in a ratio o...

Conclusions: This study demonstrated the possibility of using ethanol as the carbon source by engineered E. coli strains. It can serve as the basis for the construction of more robust strains in the future though the catabolic capacity of ethanol should be further improved. PMID: 31993378 [PubMed]

n Ali Osman Crude, phenolic-rich extracts (CPREs) were isolated from different sources, such as Hibiscus sabdariffa (H. sabdariffa), Brassica oleracea var. capitata f. rubra (B. oleracea) and Beta vulgaris (B. vulgaris) and characterized. These CPREs showed potential antibacterial and antifungal activities. H. sabdariffa CPRE (HCPRE) is the most potent, as it inhibited all tested bacteria and fungi. Total anthocyanins content (TAC), total phenolic content (TPC) and total flavonoid content (TFC) were estimated in all three CPREs. H. sabdariffa contained 4.2 mg/100 g TAC, 2000 mg/100 g of TPC and 430 mg/100 g of TFC in...

Fungal infections have increased in the last few decades as a result of the use of broad-spectrum antibiotics and the growing number of immunocompromised patients (pts), which have led to changes in the saprophytic microorganisms usually isolated. Fungal empyema (FE) is still a rare entity, with a mortality rate of 70%. Retrospective analysis of fungal pleural effusions diagnosed in our hospital between 2015 and 2018. Aseptic sampling of pleural fluid was performed by thoracentesis, chest drainage (CT) or video-assisted thoracoscopic surgery (VATS). Seventeen fungal isolates were obtained from 15 pts (12 males, mean age 60...

Abstract Gutian Hong Qu glutinous rice wine (GHQW) is a representative alcoholic beverage in China. During its traditional brewing process, multiple strains are involved. However, the roles of these microorganisms, particularly their contributions to aroma formation, are poorly understood. Therefore, in this study, the dynamics of volatile components and microbial succession during the traditional fermentation process of GHQW were monitored, by using HS-SPME-GC/MS and high throughput 16 S rRNA and ITS sequencing techniques. Following a 32-day semi-open solid-state fermentation, massive changes in volatile profil...

Abstract High glycosidase-producing strains of Aspergillus luchuensis were isolated from 2-deoxyglucose (2-DG) resistant mutants. α-Amylase, exo-α-1,4-glucosidase, β-glucosidase and β-xylosidase activity in the mutants was ~3, ~2, ~4 and ~2.5 times higher than the parental strain RIB2604 on koji-making conditions, respectively. Citric acid production and mycelia growth of the mutants, however, approximately halved to that of the parent. Compared to the parent, the alcohol yield from rice and sweet potato shochu mash of the mutant increased ~5.7% and 3.0%, respectively. The mutant strains show...

NerínAbstractThe influence of the growth of Aspergillus flavus and Escherichia coli on the concentration of the main compounds released by essential oils of cinnamon, clove and oregano has been studied. A diffusion vapour test and a subsequent analysis of three different areas of the plate were carried out. The results showed that in absence of microorganisms a gradient of concentration from the centre towards the periphery of the plate was observed for eugenol, carvacrol and cinnamaldehyde but not for thymol or linalool...
