In exploring the actinomycetes, we recently isolated a novel strain, named 04107M-2, from the soil of Taitung County with a unique morphology and possessing antibacterial and antifungal activities.
The mycelium of actinomycetes sometimes breaks apart to form coccoid or rod-shaped colonies. Many members of actinomycetes are also known to form spores with the sporangia or spore case being found on the aerial hyphae. They are easily infected by bacteriophages, and the phages that infect actinomycetes are called actinophages.
The growing resistance of microorganisms towards antibiotics has become a serious global problem. Therapeutics with novel chemical scaffolds and/or mechanisms of action are urgently needed to combat infections caused by multidrug resistant pathogens, including bacteria, fungi and viruses. Developmen …
In Progress. Progress is crucial in several aspects of actinomycetes research that includes (1) isolation and dereplication of actinomycete isolates, (2) prediction and identification novel compounds, (3) enhancing production titers of potential compounds, (4) uncovering genome information and associated biosynthetic potential, (5) collection and processing of genomic …
actinomycetes. The metabolic perspective of actinomycetes not only provides an eresting area for research but also offers the possibility of commercialization of the metabolites generated in the process. Enzymes such as amylase, lipase, and cellulases produced from actinomycetes play an important role in food,

Chemical structures of compounds with antibacterial activities. Aminocoumarins. The combined approach of phylogenetic and chemical analyses of the Streptomyces community from marine sediments of British Columbia in Canada allowed discovering a range of structurally diverse actinomycetes secondary metabolites. Four of them were determined as new novobiocin …
2.1. Karakteristik Actinomycetes Actinomycetes adalah organisme tanah yang memiliki sifat-sifat yang umum dimiliki oleh bakteri dan jamur tetapi juga mempunyai ciri khas yang cukup berbeda. Pada lempeng agar, Actinomycetes dapat dibedakan dengan mudah dengan bakteri pada umumnya. Tidak seperti koloni bakteri pada
Actinomycetes are generally Gram-positive ubiquitous, spore-forming bacteria with diverse biological activities [].They are placed within the phylum Actinobacteria, class Actinomycetia, subclass Actinobacteridae, and order Actinomycetales that consists of over 160 genera, 10 suborders, and more than 30 families [].They are considered to be one of the vast …
Actinomycetes are well known as an inexhaustible source for antibiotics. Most of the known antimicrobials today were originally isolated from actinomycetes, especially from the genus Streptomyces.The produced substances include all important drug classes used in clinics today, such as β-lactams, tetracyclines, macrolides, aminoglycosides, or glycopeptides.
Pathogenic Actinomycetes may cause damage to the fine roots. Actinomycetes were found in longitudinal sections of fibrous roots from sick soil (Figure 2). These Actinomycetes grow into young light fibrous roots, accumulate in the root cortex, and functionally damage the root. This observation correlates with the appearance of root systems from ...
Natural product derived pesticides have increased in popularity worldwide because of their high efficacy, eco-friendly nature and favorable safety profile. The development of polyketide pesticides from actinomycetes reflects this increase in popularity in …
Actinomycetes are a heterogenous group of bacteria that are gram-positive, filamentous, with a branched growth pattern. They grow in mycelium or extensive colonies. Though they are bacteria, they are a group of unique organisms that …
On behalf of the local and international organizing committees, it is my great pleasure and honor to welcome you to the 20th International Symposium on the Biology of Actinomycetes (ISBA2025). The symposium will take place at the Congresshotel Zuiderduin in the picturesque town of Egmond aan Zee, the Netherlands, from June 15th to 19th, 2025.
Actinomyces species grow optimally under anaerobic conditions. Some facultative anaerobes and aerotolerant species in this genus may grow in the presence of oxygen but …
Nutrition. Unlike cyanobacteria, Actinomycetes are heterotrophic organisms and thus depend on various organic materials as a source of food/energy.This is achieved by decomposing various organic materials (e.g. cellulose and lignin etc) in their surroundings. To effectively break down these compounds, Actinomycetes produce a number of enzymes including cellulases and …
