The outcomes are to be compared with typical drugs given that compounds are examined against gram-positive and gram-negative strains of bacteria and fungus. Against bacterial strains, products with nitro, methyl, and bromo substituents in the p-position of the benzene ring, as well as products with the nitro group at the m-position, showed very excellent activities against bacterial strains, while compounds with chloro substituent at p-position and m-position demonstrated good activity against the fungal strains Aspergillus niger and Fusarium javanicum.

Resistance to pathogenic bacteria may lead to serious health problems. Scientists found that discovering novel antimicrobial compounds is possible by exploring rarely investigated environments. Therefore, this work focused on isolating and identifying some fungal strains collected from the Co To sea. We tested whether such strains can produce compounds with vital activities, including antibacterial and antifungal. The antimicrobial activity of the marine fungi crude extracts was performed by the Bioassay method in a 96-well tray.

This study aimed to assess the antimicrobial and antioxidant activities of 61 marine fungal strains isolated from 34 samples collected in the research journey of the Akademik Oparin vessel in the North Sea of Vietnam in 2021. Of these, 23 were from sponges, 21 from seaweeds, 15 from sediments, and only 2 from seawater.

Mangrove-derived fungi are the potential source of novel metabolites, comprising unique molecular structures with diverse bioactivities. In this study, 32 fungal strains isolated from the Tan Dao mangrove forest in Khanh Hoa province were investigated for their ability to produce antimicrobial agents using the disc diffusion method.

In the context of sources for natural products discovery are going scarcer, exploiting biotechnologically potential compounds from marine microbial symbionts is considered a relatively new trend. In our study a total of fifteen fungal strains were isolated from marine algal samples belonging to species Kappaphycus cottonii, K. striatus, Gracilaria eucheumatoides and Betaphycus gelatinus collected in Nha Trang in 2017.

Marine fungi are evaluated as a potential source for new natural compounds with bioactivities of pharmaceutical values. In this study, 66 fungal strains, isolated from 37 sponge samples in Nha Trang bay, were determined for cytotoxic activity against two human cancer cell lines, including cervical cancer (Hela) and breast cancer (MCF-7) cells using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay.

A series of novel positional oximes (2a–2d), O-methyl oxime ethers (3a–3d), and O-benzyl oxime ethers (4a–4d) were synthesized in high yields starting from their corresponding methyl 3-, 4-, 6-, and 13-keto tetradecanoates. The synthesized compounds were characterized by 1H NMR, 13C NMR, FT-IR, mass, and elemental analyses for their structures and (E) /(Z) isomerizations. Their DNA binding abilities were investigated in vitro by agarose gel electrophoresis. The antibacterial and antifungal activities were tested also in vitro against eleven bacterial strains and three fungal strains.

This research evaluated the biotechnological potential of fifteen native Trichoderma strains that were previously isolated from the rhizosphere of maize cultivated at the Estado de Mexico (Mexico). The radial growth rate of each fungal strain was assessed as well as the qualitative analysis of enzyme activity on specific culture media.

Pectinases find wide application in different industrial applications, e.g., textile, food, tea, paper and pulp, vegetable oil extractions, saccharification of agricultural remains, and in fermented drinks. Three fungal strains were screened for pectinase production. Results indicated that all strains are capable of producing a pectinase enzyme.

The main mechanism of resistance in A. fumigatus involves incorporation of tandem repeats in the promoter region of cyp51A, along with point mutations in the gene sequence. Resistant isolates tend to arise either due to excessive use of azole fungicides in the agricultural fields, from where they reach human through sporulation; or by prolonged treatment of patients with azole drugs. The early diagnosis of aspergillosis is very crucial for successful treatment of a patient.

The aim of this study was to evaluate the antimicrobial activity of three commercial GSE (Grapefruit Seed Extract) products against six bacterial and one fungal strain, through the agar well diffusion method, determination of minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC). Obtained results indicate strong antimicrobial effects of investigated extracts, with different microbial susceptibility, including the multidrug-resistant (MDR) bacteria.

This study aimed to investigate the antagonistic effect of three strains of the genus Bacillus on toxigenic fungi contaminating food commodities, with emphasis on two ochratoxigenic isolates (A. ochraceus, A. westerdijkiae) and two aflatoxigenic isolates (A. flavus and A. parasiticus). In vitro studies were carried out using two different methods for cultivation tested bacilli with fungal isolates – coincubation and dual culture method.

A series of new extensively conjugated E -stilbene azomethines (5a–5h) were synthesized and screened for their antioxidant and antimicrobial activity. The compounds were tested against bacterial (Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Bacillus subtilis) and fungal strains (Aspergillus niger, A. flavus, and Trichoderma harzianum) using the agar well diffusion method.

The results showed that these fungal strains belonged to four different genera, including Aspergillus, Penicillium, Monascus, and Trichoderma. Our observation is in consistent with previous study, which found that Aspergillus, Penicillium are dominant fungi in composting materials due to their able to survive high temperatures and break down variety of bio-solid wastes. Beside of that, the two other genera Trichoderma and Monascus are widely known for their ability to break down ligninrich materials which difficult for biodegradation.

Plant biomass is the most abundant carbon source for many fungal species. In the biobased industry fungi, are used to produce lignocellulolytic enzymes to degrade agricultural waste biomass. Here we evaluated if it would be possible to create an Aspergillus nidulans strain that releases, but does not metabolize hexoses from plant biomass.
