Understanding the microbial communities in asymptomatic oil palm seedlings is crucial for developing disease-suppressive microbiota against basal stem rot (BSR) in oil palm. In this study, we compared the microbial communities in bulk soil, rhizosphere, and endosphere of control, asymptomatic, and symptomatic seedlings following inoculation with Ganoderma boninense. Our findings revealed significant shifts in microbial structure and interactions, particularly in asymptomatic seedlings.

- Soil nutrients and microbiota are crucial for healthy plant growth, yet limited research has focused on their impact during the early development of oil palm seedlings, especially in relation to NPK fertilizer.
- The study examined microbial communities in oil palm seedlings grown in various soil conditions (fertilized/unfertilized, normal/sterilized) and found that chemical fertilizers enhanced specific microbial strains but sterilization reduced microbial diversity and negatively impacted growth.
- Results suggested that beneficial microbes, which play roles in nutrient transformation and plant growth, were diminished in sterilized soils, indicating that sterilization can harm seedling development by limiting essential microorganisms.
To set a benchmark in fungal growth rate, a differential analysis of prototrophic Aspergillus fumigatus AR04 with three ascomycetes applied in > 10 t year scale was performed, i.e. Ashbya gosspyii (riboflavin), Aspergillus niger (citric acid) and Aspergillus oryzae (food-processing).

Nonetheless, a systematic comparative interpretation of metabolic changes upon vegetable oil or glucose as sole carbon source is still lacking. Selected fungi that can grow in acidic mineral salt media (MSM) with vegetable oil had been identified recently.
