“…To further identify potential genes related to the growth difference, whole genome sequences of the strains FA1, FA2, FA3, and ATCC 14048 were annotated using the cluster of orthologous groups of proteins (COG). [ 15 ] As shown in Figure 5 , the number of genes related to the essential processes for cell growth, such as translation, replication, and cell wall biogenesis, is slightly higher in strains FA1, FA2, and FA3 than in ATCC 14048 (Figure S1, Table S1, Table S2, and Figure S2, Supporting Information). [ 16 ] We also performed a comprehensive gene set analysis for these strains.…”

Vibrio is a recognized fast-growing bacterial genus, which is considered to be attractive for the development of next-generation biotechnological workhorses. Here, three Vibrio strains FA1, FA2, and FA3, capable of growing rapidly in cost-effective media, are isolated and systematically evaluated. Genome sequencing and comparative genomic analyses are performed to reveal the underlying genetic differences between the strains and estimate their biotechnological potential. Studies of their phylogenetic tree, colinear visualization, and orthology uncover some difference in the gene content related to cell growth of the four Vibrio strains FA1, FA2, FA3, and ATCC 14048, which may explain growth superiority of the isolated strains. It is noted that there are more copies of several genes related to the DNA replication in the FA2 genome than in the other compared Vibrio strains. Furthermore, the genes responsible for amino synthesis are found, such as asD, within strains FA1 and FA2. Gene cluster cadABC, which relates to cell adaptation at acidic pH, only exists in strains FA1, FA2, and FA3. Finally, the wide spectra of substrates and genetic operability of these three isolated Vibrio strains are initially verified. This study provides excellent candidates for the development of next-generation fast-growing microbial workhorses, which may be very useful in synthetic biology.

“…As a biodegradable material, polylactic acid (PLA) has good biocompatibility and degradability, which makes it widely used in medical material, 1,2 drug delivery, 3 and food packaging 4,5 . Recently, the production technology of PLA is becoming more and more mature 6 and many countries are actively improving the production capacity of PLA, 7–9 which provides a foundation for the large‐scale application of PLA. Furthermore, in the context of “carbon peak” and “carbon neutrality,” PLA is attracting unprecedented attention as the most promising alternative to petroleum‐based plastics because of its low carbon emissions and degradability, so it is very urgent to broaden the application of PLA, especially in durable materials field.…”

Halloysite nanotube (HNT) was etched by hydrochloric acid, and epigallocatechin gallate (EGCG) was loaded into the etched HNT (HH) to prepare loaded antioxidant (HH-E) for polylactic acid (PLA) with improved thermal-oxidative stability. The loading process was confirmed by TGA and FT-IR, and the loading capacity was 16.15%. The presence of EGCG on the surface of etched HNT was further confirmed by nitrogen adsorption and TEM. The effect of loaded EGCG on thermal-oxidative stability of PLA was characterized by the change in OOT values of PLA after the aging process under 140 C. The results showed that HH-E increased OOT values of PLA from 231.2 C to 293.6 C at first, indicating that HH-E provided PLA with excellent thermal-oxidative stability. Furthermore, as can be seen from the trend of OOT changing over aging time, during the 14 days aging process, OOT values of PLA composites with HH-E decreased more slowly than that of PLA composites with EGCG alone, endowing PLA with sustainable thermal-oxidative stability. Further kinetic analysis showed that the apparent activation energy of the degradation process (E a ) of PLA composites with HH-E changed less than that of PLA composites with EGCG alone, which showed that the loading system provided PLA better sustainable stability. Moreover, the isothermal crystallization process of modified PLA was characterized by DSC and POM. The results showed that HH-E provided heterogeneous crystal nucleus for PLA, reducing the half crystallization time (t 0.5 ) and improvement of crystallization rate for PLA. These results prove that HH-E exhibited excellent performance in improving the thermal stability and crystallization property of PLA, showing multifunctional characterization.
