Lichens, formed by the symbiosis of fungi and algae or cyanobacteria, are increasingly recognized for their potential medicinal properties, including their potential to treat type 2 diabetes. Many studies have shown that the bioactive metabolites of lichens originate from their fungal partners. This study isolated the mycobiont from a Graphis lichen sample and investigated the antioxidant and α-glucosidase inhibitory activity of its ethyl acetate extract.

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.

Ebook "Viruses in foods (Food microbiology and food safety series)" is the first book that comprehensively discusses the role of viruses in foodborne disease outbreaks, along with strategies for the prevention and control of viral contamination of food. Cases of viral foodborne outbreaks are on the rise in part due to the increases in population, scarcity of clean water, and changes in eating habits.

Streptomyces are considered the most potential microbes with the ability to produce antimicrobial and anticancer agents. These bacteria are found mostly in soil across the globe and play a pivotal role in material recycling processes. Isolation of Streptomyces in Vietnam has been conducted for years.

Cephalotaxus mannii Hook.f is a rare medicinal plant used for the treatment of leukemia, however, its fungal endophytes with antibacterial and anticancer properties have not been exploited yet. In this study, six fungal isolates were recovered from roots of C. mannii collected in Ha Giang province, Vietnam.

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.

Antimicrobial peptides play important roles in both plant and animal defense systems. Moreover, over-expression of CaAMP1 (Capsicum annuum antimicrobial protein 1), an antimicrobial protein gene isolated from C. annuum leaves infected with Xanthomonas campestris pv. vesicatoria, confers broad-spectrum resistance to hemibiotrophic bacterial and necrotrophic fungal pathogens in Arabidopsis.

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.

The present research was carried out to determine the anatomical features of leaves of Alangium salviifolium and their endophytic fungal association. Alangium salviifolium is an important medicinal plant with various activities reported. It is suggested that the medicinal property of the plant is either because of their endophytes or the endophytes inherit the medicinal properties from their host plant. Hence the detailed study of plant- microbe interaction is important.

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.

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.
