“…China is the largest bamboo-producing country and has about 300 species in 44 genera, occupying 3% of the global forest area, and the area of Moso bamboo ( Phyllostachys edulis ) accounts for about 74% of the total bamboo forest area ( 21 , 22 ). To improve the comprehensive utilization of bamboo resources, the health-promoting effects of bamboo have been extensively studied.…”

“…At the family level, Porphyromonadaceae, Spirochaetaceae, Lachnospiraceae, Moraxellaceae, Enterobacteriaceae, Ruminicoccaceae, and Streptococcaceae exhibited the highest species richness across all three gut-regions. The majority of the taxa of these bacterial families prefer gut systems of termites and invertebrates, comprising a diverse array of genus-level lineages ( Bourguignon et al, 2018 ; Huang et al, 2022 ; Zhang et al, 2024 ). The dominance of Porphyromonadaceae is consistent with other lower termites such as Stolotermes ruficeps ( Reid et al, 2014 ).…”

The wood-feeding termite, Coptotermes formosanus, presents an efficient lignocellulolytic system, offering a distinctive model for the exploration of host-microbial symbiosis towards lignocellulose degradation. Despite decades of investigation, understanding the diversity, community structure, and functional profiles of bacterial symbionts within specific gut regions, particularly the foregut and midgut of C. formosanus, remains largely elusive. In light of this knowledge gap, our efforts focused on elucidating the diversity, community composition and functions of symbiotic bacteria inhabiting the foregut, midgut, and hindgut of C. formosanus via metagenomics. The termite harbored a diverse community of bacterial symbionts encompassing 352 genera and 26 known phyla, exhibiting an uneven distribution across gut regions. Notably, the hindgut displayed a higher relative abundance of phyla such as Bacteroidetes (56.9%) and Spirochetes (23.3%). In contrast, the foregut and midgut were predominantly occupied by Proteobacteria (28.9%) and Firmicutes (21.2%) after Bacteroidetes. The foregut harbored unique phyla like Candidate phylum_TM6 and Armatimonadetes. At the family level, Porphyromonadaceae (28.1, 40.6, and 53.5% abundance in foregut, midgut, and hindgut, respectively) and Spirochaetaceae (foregut = 9%, midgut = 16%, hindgut = 21.6%) emerged as dominant families in the termite’s gut regions. Enriched operational taxonomic units (OTUs) were most abundant in the foregut (28), followed by the hindgut (14), while the midgut exhibited enrichment of only two OTUs. Furthermore, the functional analyses revealed distinct influences of bacterial symbionts on various metabolic pathways, particularly carbohydrate and energy metabolisms of the host. Overall, these results underscore significant variations in the structure of the bacterial community among different gut regions of C. formosanus, suggesting unique functional roles of specific bacteria, thereby inspiring further investigations to resolve the crosstalk between host and microbiomes in individual gut-regions of the termite.

“…Interestingly, many bacterial genera of animal origin, associated with human and animal gut microbiota were found to have increased in relative abundance. These include Turicibacter, which has been reported from metagenomic and meta-transcriptome studies to be predominant, especially in the fermentation of compost, and known to harbour various hydrolytic enzymes associated with the degradation of plant lignocellulose (Huang, et al 2022). The genus Romboutsia, belong to Peptostreptococcaceae family within the Firmicutes, these anaerobic bacteria species are adapted to environments that are rich in nutrients but primarily known to play a major role in the degradation of carbohydrates (Jacoline, et al 2019).…”

Improper disposal of used motor oil is a prevalent issue in developing countries, leading to a notable contribution to environmental pollution. This study was conducted using the 16S rRNA targeted metagenomic approach, to assess the changes in bacterial population diversity and abundance at an oil contamination experimental site in Botswana. To demonstrate the impact of used motor oil is on the soil ecosystem, soil samples collected at different depths before and after treatment with used motor oil were subjected to total community DNA extraction and Illumina sequencing. The taxonomic bacterial composition data revealed statistically significant differences among the treatments and controls. A notable shift from Gram-negative to Gram-positive bacterial populations was observed following treatment with used motor oil. Prevotella and Aerococcus were among the few genera within the enriched Gram-positive bacteria that could be directly linked to biodegradation of the polycyclic aromatic hydrocarbons associated with oil contamination. Agricultural and biotechnologically important, plant-associated bacterial genera; Methylobacterium-methylorumbrum, Bradyrhizobium, and, Phyllobacterium significantly declined in relative abundance, thus demonstrating the negative impact of oil contamination. The results from this study, improves our understanding of the roles of indigenous soil bacteria, and can help in guiding future strategies for the sustainable management of contaminated soils globally in countries with similar climatic and ecological conditions.
