ABSTRACT BACKGROUND Millions of tons feather waste from the poultry industry are disposed annually despite containing a high level keratin. The aim this study was to compare hydrolysis non‐treated using three different approaches (whole cell microbial digestion, enzymatic and chemical cleavage) test use hydrolysates as peptone substitutes in culture medium. RESULTS Among bacterial isolates, Pseudomonas sp. P5 exhibited highest keratinolytic activity efficiency hydrolyse raw material....
Electrospun polyamide (PA) nanofibers have great potential for medical applications (in dermatology as antimicrobial compound carriers or surgical sutures). However, little is known about microbial colonization on these materials. Suitable methods need to be chosen and optimized the analysis of biofilms formed influence their morphology biofilm formation. We analyzed 11 PA nanomaterials, both nonfunctionalized functionalized with AgNO3, tested formation a by clinically relevant bacteria...
Despite the diligent efforts of libraries, archives, and similar institutions to preserve cultural monuments, biodeterioration continues pose a significant threat these objects. One main sources microorganisms responsible for process is presence airborne microorganisms. Therefore, this research aims monitor compare outcomes both culture-dependent (utilising various cultivation strategies) culture-independent approaches (RNA-based sequencing) identifying metabolically active in archives Czech...
Abstract In this study, we explored and described various parameters of microbially induced calcite precipitation (MICP) using the alkaliphilic bacterium Sporosarcina pasteurii DSM 33, which exhibits ureolytic activity, to stabilize strengthen waste concrete fines (WCF). Bacterial cell concentration, single repeated addition bacterial suspension, pH adjustment were tested in stage 1 experimental agenda order tune for sample preparation 2 focused on effect MICP treatment duration (14, 30, 60,...
Although fertilization and crop rotation practices are commonly used worldwide in agriculture to maximize yields, their long-term effect on the structures of soil microorganisms is still poorly understood. This study investigated impact microbial diversity community structure four different locations with three types. Since 1996, manure (MF; 330 kg N/ha), sewage sludge (SF; SF3x; 990 NPK (NPK; N/ha) fertilizers were periodically applied soils classified as chernozem, luvisol cambisol, which...
An understanding of how fertilization influences endophytes is crucial for sustainable agriculture, since the manipulation plant microbiome could affect fitness and productivity. This study was focused on response microbial communities in soil tubers to regular application manure (MF; 330 kg N/ha), sewage sludge (SF; SF3x; 990 chemical fertilizer (NPK; 330-90-300 N-P-K/ha). Unfertilized used as a control (CF), experiment set up at two distinct sites. All treatments significantly altered...
Abstract The feature of elastin‐like proteins (ELPs) to reversibly precipitate above their transition temperature was exploited as a general method for the purification histidine (His)‐tagged proteins. principle single‐step metal‐affinity is based on coordinated ligand‐bridging between modified ELPs and target with repeating sequences [(VPGVG) 2 (VPGKG)(VPGVG) ] 21 were synthesized free amino groups lysine residues by reacting imidazole‐2‐carboxyaldehyde incorporate metal‐binding ligands...
The benzonitrile herbicides bromoxynil, chloroxynil, dichlobenil, and ioxynil have been used actively worldwide to control weeds in agriculture since 1970s. Even though dichlobenil is prohibited EU 2008, studies addressing the fate of environment show that some metabolites these are very persistent. We tested cytotoxic effects their microbial using two human cell lines, Hep G2 HEK293T, representing liver kidneys as potential target organs humans. viability proliferation were determined by...
Increasing microbial safety and prolonging the shelf life of products is one major challenges in food industry. Active packaging made from nanofibrous materials enhanced with antimicrobial substances considered a promising way. In this study, electrospun polyamide (PA) functionalized 2.0 wt% natamycin (NAT), rosemary extract (RE), green tea (GTE), respectively, were prepared as active tested for pathogens Escherichia coli , Listeria monocytogenes Salmonella enterica Staphylococcus aureus ....
Abstract BACKGROUND The production and consumption of chicken has doubled in the last 17 years. Since slaughter yields range from 70 to 80%, during various waste residues are generated. One these is created after mechanical separation meat (W‐MSM). goal circular economy manage this transform it into a valuable product. RESULTS W‐MSM was subjected hydrolysis by proteolytic enzymes pepsin papain obtain bioactive compounds. Papain digestion resulted several times higher chondroitin sulfate...
Fertilization is a worldwide agricultural practice used in agronomy to increase crop yields. Fertilizer application influences overall soil characteristics, including microbial community composition and metabolic processes mediated by enzymatic activity. Changes the structure of communities their activity after long-term fertilization were studied this research. We hypothesized that different types regimes affect nutrient levels which subsequently influence diversity structure. Manure (MF;...
Natural antimicrobial agents used as food additives and for active packaging development are a promising way to reduce food-associated microbial risks. We compared the antibacterial antibiofilm effect of seven natural-origin suitable (calcium lactate, citric acid, curcumin, erythorbic garlic extract, hop nisin) against Listeria monocytogenes, Staphylococcus aureus, Escherichia coli. Minimal inhibitory concentration (MIC) MIC biofilm formation (MICBF) were determined. All tested substances...
Abstract BACKGROUND Biochars have become one of the most intensively and extensively investigated soil amendment materials in terms their production, application fate because benefits such as increased quality fertility. Biochar from woodchips bone char meat waste a poultry slaughterhouse were prepared at 300 500 °C then thoroughly mixed with two soils (cambisol luvisol) that differed physicochemical parameters ratios 2% 5% (w/w). RESULTS The impact biochar amendments on nutrient...
