“…Microorganisms are cosmopolite organisms which can live in various places on earth [1], including in extreme environments, such as heavy metal contaminated environments [2] or high radiation exposure [3]. Microorganisms living in high radiation environments are known to have phenotypically sophisticated characters, as well as molecular repair mechanisms that can prolong their survival under extreme radiation [4].…”

Bacteria which are living in extreme environment have potential for bioprospection as candidates for drug discovery and bioremediation. Radiation-resistant bacteria can be obtained from environments that have radiation sources. Pool water containing radioactive material is one of the important components in the Iradiator Gamma Karet Alam (IRKA) facility. Research on the presence of bacterial communities in the IRKA cooling pool water has never been conducted. This study was conducted to determine the bacterial community of IRKA cooling pool water using Nanopore Sequencing. The study identified 7 phyla, with Proteobacteria and Firmicutes as the dominant with 95.9 and 3.9%, respectively. Phreatobacter, specifically P. oligotrophus, emerged as the dominant genus and the most prevalent species, constituting 71.22% of the cooling pool water samples at the IRKA facility. The limited number of studies conducted on these dominant species presents an opportunity for further exploration of their potential benefits.

Introduction: Suckermouth catfish are invasive alien species in Malaysia with rapid population propagation, causing negative impacts on the local ecology and economy. Presently, there are no available methods to sufficiently control their populations. The aim of this study is to explore the potential of suckermouth catfish as a source of ingredients for the pharmaceutical industry, which could encourage their utilisation and indirectly control their population. Methods: In this study, acid-soluble collagen extraction was carried out, followed by identification tests, yield calculations, and some basic physical characteristic tests. Results: The extracted collagen was described as off-white and had a strong acetic acid odour. The mean yield of collagen on a wet basis was 10±2.3%, with a hydroxyproline content of 1.6%, while the viscosity and pH of a 20% collagen solution were 0.6±0.25 mPa.s and 5.51±0.1, respectively, comparable to previous studies using various species of fish. Heavy metal contents of the extracted collagen were also found to be within the acceptable limits for use in pharmaceutical and cosmetic applications. Conclusion: This study concludes that the skin of suckermouth catfish is a promising source of collagen for potential industrial applications. However, further studies are needed to improve the yield and purity and establish the physicochemical characteristics, safety, and applications of the extracted collagen.
