In an earlier study, we reported the presence of the antibiotic, heptelidic acid, in the fungus, Gliocladium virens1). From this same organism we have isolated two additional compounds, one of which is selectively active against members of the Oomycetes2). We call this compound gliovirin (1). The second compound, L,L-phenylalanine anhydride (9), may be the biosynthetic precursor to gliovirin. G...

Abstract. Istiqomah L, Cahyanto MN, Zuprizal. 2022. Xylanase production by Trichoderma virens MLT2J2 under solid-state fermentation using corn cob as a substrate. Biodiversitas 23: 6530-6538. is one of non-starch polysaccharide (NSP) degrading enzyme encompass in industrial application like animal feed, food, biofuel, and textile. The objective this study was to produce characterize the crude x...

We surveyed the Trichoderma (Hypocreales, Ascomycota) biodiversity in agricultural fields in four major agricultural provinces of East China. Trichoderma strains were identified based on molecular approaches and morphological characteristics. In three sampled seasons (spring, summer and autumn), 2078 strains were isolated and identified to 17 known species: T. harzianum (429 isolates), T. asper...

The marine environment is becoming increasingly contaminated by environmental pollutants with the potential to damage DNA, with marine sediments acting as a sink for many of these contaminants. Understanding genotoxic responses in sediment-dwelling marine organisms, such as polychaetes, is therefore of increasing importance. This study is an exploration of species-specific and cell-specific dif...

Trichoderma virens is a mycoparasitic fungus used in biocontrol of soilborne plant pathogens. It inhibits or kills plant-pathogenic fungi through production of antifungal antibiotics and parasitism of hyphae and sclerotia. Conidiation, or the production of asexual spores, an inducible process triggered by light or nutrient stress, is an important trait in survival and also development of formul...

We provide occurrence records of the members dung beetle's tribe Onitini from northern parts Pakistan, including Gilgit-Baltistan, Khyber Pakhtunkhwa Province and Islamabad Capital Territory. This study is based on extensive field sampling different ecological biomes Alpine Meadows, Sub-Alpine Zone, Mountain Temperate Forest, Subtropical Deciduous Forest. As a result, we report six species unde...

Problem statement: Plant derived fungicides are now being subjects of many research groups. These secondary metabolites have enormous potential to inspire and influence modern agrochemical research. The study aimed to investigate the antifungal activity and their potential use as fungicides in the agriculture of crude extracts and purified compounds derived from plants used in traditional medic...

BACKGROUND The pan-tropical genus Ardisia has more than 400 species and is of high horticultural and medicinal value. Due to overexploitation it is important to conserve the germplasm of this genus. OBJECTIVE To investigate the feasibility and methods of cryopreservation for long-term seed storage of three Ardisia species: A. elliptica Thunb., A. brunnescens Walker, and A. virens Kurz. METH...
