“…As shown in Table S 7 , the 102 new species identified in hGMB belonged to 24 different families (including 3 novel families), and Lachnospiraceae was the most abundant family including 29 new species and 7 new genera ( Wujia gen. nov., Simiaoa gen. nov., Jutongia gen. nov., Qiania gen. nov., Zhenhengia gen. nov., Jingyaoa gen. nov., and Wansuia gen. nov.). Similarly, Lachnospiraceae is one of the most dominant families in the GM of healthy adults, accounting for 10–45% of the total bacteria in feces [ 51 ], and is considered to play diverse but controversial roles in the maintenance of host gut homeostasis [ 27 , 52 ]. On the one hand, Lachnospiraceae members, such as the Roseburia species, were beneficial to hosts via the production of short-chain fatty acids (SCFAs) and secondary bile acids [ 53 – 55 ], protection of hosts from pathogen infections [ 54 , 56 , 57 ], and stress-induced visceral hypersensitivity [ 53 ].…”

Background In gut microbiome studies, the cultured gut microbial resource plays essential roles, such as helping to unravel gut microbial functions and host-microbe interactions. Although several major studies have been performed to elucidate the cultured human gut microbiota, up to 70% of the Unified Human Gastrointestinal Genome species have not been cultured to date. Large-scale gut microbial isolation and identification as well as availability to the public are imperative for gut microbial studies and further characterizing human gut microbial functions. Results In this study, we constructed a human Gut Microbial Biobank (hGMB; homepage: hgmb.nmdc.cn) through the cultivation of 10,558 isolates from 31 sample mixtures of 239 fresh fecal samples from healthy Chinese volunteers, and deposited 1170 strains representing 400 different species in culture collections of the International Depository Authority for long-term preservation and public access worldwide. Following the rules of the International Code of Nomenclature of Prokaryotes, 102 new species were characterized and denominated, while 28 new genera and 3 new families were proposed. hGMB represented over 80% of the common and dominant human gut microbial genera and species characterized from global human gut 16S rRNA gene amplicon data (n = 11,647) and cultured 24 “most-wanted” and “medium priority” taxa proposed by the Human Microbiome Project. We in total sequenced 115 genomes representing 102 novel taxa and 13 previously known species. Further in silico analysis revealed that the newly sequenced hGMB genomes represented 22 previously uncultured species in the Unified Human Gastrointestinal Genome (UHGG) and contributed 24 representatives of potentially “dark taxa” that had not been discovered by UHGG. The nonredundant gene catalogs generated from the hGMB genomes covered over 50% of the functionally known genes (KEGG orthologs) in the largest global human gut gene catalogs and approximately 10% of the “most wanted” functionally unknown proteins in the FUnkFams database. Conclusions A publicly accessible human Gut Microbial Biobank (hGMB) was established that contained 1170 strains and represents 400 human gut microbial species. hGMB expands the gut microbial resources and genomic repository by adding 102 novel species, 28 new genera, 3 new families, and 115 new genomes of human gut microbes.

“…Elephants around Rawa Bunder Camp are looking for food and minerals. Minerals are needed for various biological processes, including energy metabolism, organs and immunity, reproductive function, and cell growth (Ishiguro et al 2018). Elephants have a home range of 32.4-166.9 km², which includes various types of forest ecosystems, namely swamp forest, lowland rainforest, peat forest, and mountain rainforest (Mahanani et al 2012).…”

The importance of research on the Rawa Bunder Resort’s landscape characteristics at Way Kambas National Park (WKPN) is as a basis for area management according to its function in a lowland tropical rain forest ecosystem. The purpose of this study is to find out the current characteristics of landscape include physical and biological characteristics as well as the driving factors for the establishment of good habitat restoration for flora and fauna life. The results showed that the landscape characteristics of the Rawa Bunder Resort consisted of natural forest and open land containing shrubs with almost the same area composition. The position of the forest appears to be united in the middle to the east of the WKNP. The pressure of Imperata fires can threat the existence of forests. If the preventive action is not taken immediately, the forest will decrease in size. The driving factor for the reduction of the forest matrix is the frequent occurrence of forest fires every year. These fires were triggered by humans who intentionally or unintentionally driven by the wind so that it spread widely.

Natural products interest is gradually increasing worldwide. Plant-food-derived bioactives have a long history of use as a good source of ingredients for valuable medical usages. Plant-based foods consist of micro and macronutrients, and bioactive components, with health-promoting benefits. The handling of complex mixtures of plants has been methodically switched by therapies using a single isolated substance. The delivery of bioactive molecules in nanosystems is enhancing their bioavailability, it is much safer and cost-effective. However, there are many challenges in combining bioactive substances in nanocarrier materials.A discussion related with nanocarriers will be done in this review.
