Article Synopsis
- Soil ecosystems are complex and diverse, with this study using whole gene sequencing (WGS) to analyze microbial diversity and stress-response genes in soil samples from two distinct forests to gain more insights into their composition and function.
- The research findings showed that Proteobacteria were the most abundant microorganisms, comprising over 48% to 52% of microbial diversity, with significant differences in acidic stress-response genes related to soil pH levels.
- Taxonomic analysis indicated that both forests are dominated by bacteria, with Royal Belum showing 98% bacterial presence and Raja Musa having up to 98% as well, while Archaea and other life forms comprised only a small fraction of the total diversity.
The assessment of water-extractable organic matter using an autoclave can provide useful information on physical, chemical, and biological changes within the soil. The present study used virgin forest soils from Chini Forest Reserve, Langkawi Island, and Kenyir Forest Reserve (Malaysia), extracted using different extraction methods. The dissolved organic carbon (DOC), total dissolved nitrogen (TDN), total dissolved phosphorus (TDP), and ammonium-nitrate content were higher in the autoclave treatments, up to 3.

Therefore, the present study attempts for the use of virgin soils from Peninsular Malaysia as growth enhancer. Soils collected from Raja Musa Forest Reserve (RMFR) and Ayer Hitam Forest Reserve (AHFR) were treated using different extraction methods.

This study identified the influence of aquaculture sludge extract (SE) on four microalgae species. Conway or Bold's Basal Media (BBM) was supplemented with SE collected from a Sabak Bernam shrimp pond (SB) and Kota Puteri fish pond (KP), and tested using a novel microplate-incubation technique.
