Development of Antifungal Packaging From Low ‐Density Polyethylene With Essential Oil of Oregano and Potassium Sorbate
Antifungal low-density polyethylene films were formulated with oregano essential oil. Oregano essential oil modifies the physical properties of low-density polyethylene films. Potassium sorbate influences the barrier properties of low-density polyethylene films. ABSTRACTAntimicrobial low-density polyethylene (LDPE) films were developed by adding 0%, 0.5%, 1.0%, 2.5% and 5.0% (w/w) of Mexican oregano essential oil (OEO) or potassium sorbate (PS) as a positive antifungal control to inhibit the growth ofPenicillium expansum,Penicillium citrinum andAspergillus niger in vitro. Three methods of adding OEO in LDPE were evaluate...

Reports of Pennellidae Burmeister, 1835 (Copepoda: Siphonostomatoida) post metamorphosed females off the coast of southern Africa
Syst Parasitol. 2024 Apr 22;101(3):32. doi: 10.1007/s11230-024-10157-0.ABSTRACTSeven species belonging to Pennellidae are reported from marine teleosts caught off southern Africa. Additionally, complete re-descriptions are provided for Propeniculus stromatei and Sarcotretes scopeli. Examination of Lernaeenicus gonostomae, deposited in the Iziko South African Museum, indicated that it has the morphological features of Sarcotretes rather than Lernaeenicus and thus should be moved to Sarcotretes i.e. S. gonostomae n. comb. for which a re-description is also provided. Reports of new host records include those of Pennella instr...

Evaluation of multi-heavy metal tolerance traits of soil-borne fungi for simultaneous removal of hazardous metals
The objective of the present study was to isolate the fungi from the agricultural soil of Kashmir valley, investigate their multi-metal tolerance to heavy metals and evaluate the metal uptake capacities of the resistant fungi. The fungi were isolated and identified on the basis of morphological and molecular approach (ITS1 and ITS4). The tolerance limits of the isolated fungal strains to various doses of lead (Pb), cadmium (Cd), zinc (Zn), chromium (Cr), copper (Cu), nickel (Ni), and cobalt (Co) was evaluated. Five fungal strains,Aspergillus niger, Fusarium oxysporum, Fusarium verticillioides,Aspergillus fischeri, Epicoccu...

A catalytic membrane approach as a way to obtain sweet and unsweet lactose-free milk
Bioprocess Biosyst Eng. 2024 Apr 22. doi: 10.1007/s00449-024-03018-z. Online ahead of print.ABSTRACTThe growing need in the current market for innovative solutions to obtain lactose-free (L-F) milk is caused by the annual increase in the prevalence of lactose intolerance inside as well as the newborn, children, and adults. Various configurations of enzymes can yield two distinct L-F products: sweet (β-galactosidase) and unsweet (β-galactosidase and glucose oxidase) L-F milk. In addition, the reduction of sweetness through glucose decomposition should be performed in a one-pot mode with catalase to eliminate product inhib...

Antifungal efficiency and mechanisms of ethyl ferulate against postharvest pathogens
This study evaluated the antifungal activity of ethyl ferulate (EF) and explored its mechanisms of action against Alternaria alternata, Aspergillus niger, Botrytis cinerea, Penicillium expansum, Penicillium digitatum, Geotrichum candidum and evaluated its potential to inhibit postharvest decay. The results demonstrated that EF exerts potent antifungal activity against a wide board of postharvest pathogens. Results also revealed that its antifungal mechanism is multifaceted: EF may be involved in binding to and disturbing the integrity of the fungal plasma membrane, causing leakage of intracellular content and losing normal...

Characterization of Bacillus amyloliquefaciens PM415 as a potential bio-preserving probiotic
Arch Microbiol. 2024 Apr 20;206(5):222. doi: 10.1007/s00203-024-03953-1.ABSTRACTAnimal feed is vulnerable to fungal infections, and the use of bio-preserving probiotics has received increasing attention. In contrast to Lactobacillus and Bifidobacteria spp., fewer Bacillus spp. have been recognized as antifungal probiotics. Therefore, our objective was to screen antifungal strains and provide more Bacillus candidates to bridge this gap. Here, we screened 56 bacterial strains for cyclic lipopeptide genes and conducted an antifungal assay with Aspergillus niger as a representative fungus. We found that a Bacillus strain Bacil...

Alternative splicing analysis of lignocellulose-degrading enzyme genes and enzyme variants in Aspergillus niger
Appl Microbiol Biotechnol. 2024 Apr 19;108(1):302. doi: 10.1007/s00253-024-13137-y.ABSTRACTAlternative splicing (AS) greatly expands the protein diversity in eukaryotes. Although AS variants have been frequently reported existing in filamentous fungi, it remains unclear whether lignocellulose-degrading enzyme genes in industrially important fungi undergo AS events. In this work, AS events of lignocellulose-degrading enzymes genes in Aspergillus niger under two carbon sources (glucose and wheat straw) were investigated by RNA-Seq. The results showed that a total of 23 out of the 56 lignocellulose-degrading enzyme genes had ...

Fungicidal efficiency of DBD cold plasma against Aspergillus niger on dried jujube
This study investigated the fungicidal efficiency and mechanism of action of dielectric barrier discharge cold atmosphere plasma (DBD-CAP) in inactivating Aspergillus niger (A. niger) spores. The disinfection efficacy and quality of dried jujube used as the processing application object were also studied. The results indicated that the Weibull + Tail model performed better for spore inactivation curves at different voltages among various treatment times, and the spore cells were reduced by 4.05 log (cfu/mL) in spores suspension at 70 kV after 15 min of treatment. This disinfection impact was further supported by scanning e...
