The formation of oral biofilms is thought to be important in the pathogenesis of oral infections such as dental caries and periodontal disease. Oral biofilms are formed by the attachment of initial colonizers to the tooth surface, followed by the attachment and aggregation of a wide variety of oral bacteria to form mature biofilms (1) .Although brushing with a toothbrush can remove oral biofilms (2, 3) , various bacteria have been reported to adhere to toothbrushes following use. These include Enterobacteriaceae and Micrococcaceae (4) , Streptococcus, Actinomyces, Porphyromonas, and Fusobacterium (5) , which are

“…At the same time, attentions of researchers are preferably focused on improving the behavior of challenging soft soils by randomly distribution of bamboo fibers. Sato et al [ 83 ] have extensively investigated the improvement of soft clay by incorporating bamboo chips and flakes at the consideration of moisture absorption characteristic of bamboo material. However, studies conclude that improvement of soft soils by incorporating bamboo fibers alone (RDFS) is limited to only a certain level due to the absence of bonding/solidifying material [ 78 , 83 ].…”

Incorporating sustainable materials into geotechnical applications increases day by day due to the consideration of impacts on healthy geo-environment and future generations. The environmental issues associated with conventional synthetic materials such as cement, plastic-composites, steel and ashes necessitate alternative approaches in geotechnical engineering. Recently, natural fiber materials in place of synthetic material have gained momentum as an emulating soil-reinforcement technique in sustainable geotechnics. However, the natural fibers are innately different from such synthetic material whereas behavior of fiber-reinforced soil is influenced not only by physical-mechanical properties but also by biochemical properties. In the present review, the applicability of natural plant fibers as oriented distributed fiber-reinforced soil (ODFS) and randomly distributed fiber-reinforced soil (RDFS) are extensively discussed and emphasized the inspiration of RDFS based on the emerging trend. Review also attempts to explore the importance of biochemical composition of natural-fibers on the performance in subsoil reinforced conditions. The treatment methods which enhances the behavior and lifetime of fibers, are also presented. While outlining the current potential of fiber reinforcement technology, some key research gaps have been highlighted at their importance. Finally, the review briefly documents the future direction of the fiber reinforcement technology by associating bio-mediated technological line.

Sato et al [11] have extensively in- As described above, various studies on soil improvement using bamboo waste materials have been conducted all over the world. From the results of the past research, it can be judged that the ground improvement by the bamboo waste material can be applied to the embankment work at general civil engineering sites and the levee embankment at the agricultural field.…”

For soil improvement, a method using plant fiber has been used since ancient times. In recent years, the construction method using plant fiber has attracted attention as a ground improvement technology with less environmental load. In this work, the soil improvement effect using waste bamboo fiber was experimentally examined. The liquid limit and plastic limit of the mixed soil tended to increase with increasing bamboo fiber content and there was no change in the plasticity index of the mixed soil by the difference of bamboo fiber content. As a result from the compaction test and unconfined compression test, it was revealed that mixing of bamboo fiber resulted in a reduction of soil material required for construction and increasing in strength. The maximum compressive stress of the bamboo fiber mixed soil at the mixing ratio of 0%, 1%, 3% and 5% were 115, 108, 130 and 152 kN/m 2 , respectively. As the soil with fiber showed the lower stiffness and higher strength than that without fiber in the dry region, it can be judged that the addition of fiber brought ductility to the soil. And it was found that the decrease in the stiffness of the specimen due to the increase of water content was suppressed by the addition of the bamboo fiber. From the results of the observation with the digital microscope, it was observed that the two-layer structure consisting of the main relatively thick fibrous structure and the secondary capillary fibrous structure were formed. Thus, it was found that the complex structure of the bamboo fiber is deeply involved in the strength of the mixed soil.
