TL;DR: The microbial transformation of five flavans by endophytic fungi isolated from the tea plant Camellia sinensis was investigated and it was found that (-)-gallocatechin 3-O-gallate, (-)-catechin (ent-1) and (+)-epicatechin (ENT-2), which possess a 2S-phenyl substitution, resisted the biotransformation.
Abstract: The microbial transformation of five flavans (1—5) by endophytic fungi isolated from the tea plant Camellia sinensis was investigated. It was found that the endophytic filamentous fungus Diaporthe sp. oxidized stereoselectively at C-4 position of (+)-catechin (1) and (−)-epicatechin (2) to give the correspondent 3,4-cis-dihydroxyflavan derivatives (6, 10), respectively. (−)-Epicatechin 3-O-gallate (3) and (−)-epigallocatechin 3-O-gallate (4) were also oxidized by the fungus into 3,4-dihydroxyflavan derivatives (10, 12) via (−)-epicatechin (2) and (−)-epigallocatechin (11), respectively. Meanwhile, (−)-gallocatechin 3-O-gallate (5), (−)-catechin (ent-1) and (+)-epicatechin (ent-2), which possess a 2S-phenyl substitution, resisted the biotransformation.

01 Jun 2018TL;DR: In this paper, the physical and thermal properties of various potential starch, i.e., corn, cassava, and potato, were evaluated by optical microsopy, DSC, and FTIR, respectively.
Abstract: Starch-based plastic is developed for petroleum-based plastic material replacement. Thus, basic knowledge of starch properties is important. This research aimed to evaluate the physical and thermal properties of various potential starch, i.e. corn, cassava, and potato starch. Granule size, thermal property, and functional group of starch were determined by optical microsopy, DSC, and FTIR, respectively. Our results demonstrated that the properties of starch (e.g. granule morphology and thermal property) varied according to its different sources. Potato starch has a bigger granule size and lower gelatinization temperature compare to corn and cassava starch. This implied that the granule size of starch affected gelatinization temperature. The larger the granule size, the more easily the starch to be gelatinized.

TL;DR: This work reports new mitochondrial DNA sequence data from tarsiers sampled from several populations, including the extreme northeast and southwest of the range of the Tarsius tarsier species complex, the most extensive sampling ever reported for this taxon, and produces the first ever molecular chronometric analysis of Tarsiidae.
Abstract: We report new mitochondrial DNA sequence data from tarsiers sampled from several populations, including the extreme northeast and southwest of the range of the Tarsius tarsier species complex, the most extensive sampling ever reported for this taxon. Our results provide the opportunity to produce the first ever molecular chronometric analysis of Tarsiidae. These results date the age of crown tarsiers, minimally, to the middle Miocene, and each of the 3 tarsier species groups, Tarsius bancanus, T. syrichta, and the T. tarsier complex, to the early or middle Miocene. Thus, each of these 3 species has evolved in isolation for a period of time that is consistent with that which would be expected for multiple speciation events. Our analysis of the Tarsius tarsier complex reveals 5 subclades, each of which is interpreted to represent a haplogroup at, or above, the species level, a result that is consistent with current hypotheses about numerous cryptic species within this species complex. The implications for conservation within the Sulawesi biogeographic region are that Sulawesi is subdivided into numerous subregions of endemism and that, by extrapolating the example of cryptic tarsier species to other taxa, biodiversity may be underestimated by an order of magnitude. The practical realties of conservation in Sulawesi are such that it is most reasonable to assume that anthropogenic extinctions are occurring, and that some species will go extinct before they have even been identified.

TL;DR: In this paper, the authors examined whether market data and expert opinion could be used to identify bird species that may be at risk from the trade in Indonesia and found that severely declining species have a significantly different price-volume signal than stable/increasing species.
