Aspergillus niger LOCK 62 produces an antifungal chitinase. Different sources of chitin in the medium were used to test production Chitinase was most effective when colloidal and shrimp shell as substrates. The optimum incubation period for chitinase by 6 days. purified from culture fractionation with ammonium sulfate affinity chromatography. molecular mass enzyme 43 kDa. highest activity obtained at 40 °C both crude enzymes. stable during 180 min °C, but lost about 25 % its under these...
Cold plasma is a new technology of promising potential to use as part technological extraction lines constructed implement green chemistry solutions or simply reduce resources in solvent-based lines. The present study was undertaken verify the effect nitrogen cold pre-treatment conducted for 8 min (20 kHz) on content antioxidants, antioxidant activity, profile volatile compounds, microbial count, pH and color measured herb extracts (12 herbs: Echinacea purpurea; Salvia officinalis; Urtica...
The rapid growth of the human population in recent decades has resulted intensive development various industries, urban agglomerations and increased production medicines for animals humans, plant protection products fertilizers on an unprecedented scale. Intensive agriculture, expanding areas newly established industrial plants release huge amounts pollutants into environment, which, nature, are very slowly degraded or not decomposed, which leads to their accumulation water terrestrial...
To improve enzyme stability, the immobilization process is often applied. The choice of a support on which enzymes are adsorbed plays major role in enhancing biocatalysts’ properties. In this study, bio-based (i.e., chitosan, coffee grounds) and synthetic Lewatit VP OC 1600) supports were used lipases various microbial origins (yeast (Yarrowia lipolytica) mold (Aspergillus oryzae)). results confirmed that proteins had been surface selected carriers, but not all them revealed comparably high...
Currently, natural polymer materials with bactericidal properties are extremely popular. Unfortunately, although the biopolymer material itself is biodegradable, its enrichment compounds may affect efficiency of biodegradation by soil microflora. Therefore, primary objective this study was to evaluate utility fungi belonging genus Trichoderma in facilitating degradation chitosan film modified cinnamic acid and ellagic environment. Only two strains (T.07 T.14) used films as a source carbon...
The most important ligninolytic enzymes in lignin degradation include laccases and peroxidases (lignin peroxidase, manganese versatile peroxidase). White-rot fungi (e.g., Cerrena sp., Phlebia sp. or Trametes sp.) are their main source nature. ability of to degrade both phenolic non-phenolic compounds has found its application sustainable agriculture. In recent years, enzymes’ role been demonstrated the biodegradation lignin, a poorly degradable component plant biomass, removing hazardous...
The purpose of this study was to assess the ability Bacillus aryabhattai RAF 5 produce P(3HB) under conditions periodic medium renewal (PMR). polymer isolated and confirmed using transmission electron microscopy (TEM), which revealed presence more than 10 dense granules per cell. purity evaluated Fourier transform infrared spectroscopy (FTIR). maximum concentration reached 18.70 g/L with biomass accumulation 21.44 after 120 h incubation PMR conditions, is 6.61 higher obtained standard...
This paper presents the results of study on production protease by Bacillus luteus H11 isolated from an alkaline soda lime. B. was identified as alkalohalophilic bacterium, and its extracellular serine endoprotease also showed extreme alkali- halotolerance. It remarkably stable in presence NaCl up to 5 M. The enzyme active a broad range pH values temperatures, with optimum 10.5 temperature 45 °C. had molecular mass about 37 kDa activity against azocasein synthetic substrate for...
The research was aimed at determining the abundance of biofilm formation by Escherichia coli and Staphylococcus aureus on surface polycaprolactone (PCL) with polyhexamethylene guanidine (PHMG) derivatives effect extracellular hydrolytic enzymes intracellular dehydrogenases. Biofilm determined spectrophotometry, using crystal violet staining. Hydrolytic after contact film were use non-specific substrate—fluorscein diacetate. PHMG dehydrogenases activity assessed test, where...
Industrialization, intensive farming, rapid population growth and urbanization are the source of a large number pollutants entering environment. The current concentration xenobiotics released into environment exceeds its natural ability to decompose them. Enzymatic degradation seems be an environmentally friendly process. Due wide spectrum substrate specificity, from inorganic compounds high molecular weight organic such as PAH or dyes, well favorable biochemical properties, laccase has been...
The Stenotrophomonas maltophilia synthesises high‐activity chitinase in response to chitin or chitosan induction. enzyme was purified 8.5 fold and subjected characterisation. optimum hydrolysis conditions for this when using colloidal as substrate were pH 5.6 temperature of 45 ° C. demonstrated high thermal stability at C within 2 h. studied exhibited activity towards chitin, glycol chitosan, while it did not hydrolyse glycosidic bonds carboxymethylcellulose. the highest activity, equalling...
Abstract The aim of this research was to correlate the sarcoplasmic protein profile natural drip loss muscle with technological and sensory quality pork meat. Material for analysis taken from 14 PenArLan pigs. Simple relationships between test meat traits showed that they adopt a range –0.58 0.72. It has been shown significance glycolysis expressed as level glycogen lactic acid may be 86% (coefficient correlations, C R = 0.93), explained by amount certain enzymes. higher relation obtained...
