“…While for Klebsiella sp. MD21, by utilizing saw dust as substrate, the maximum activities for endoglucanase, exoglucanase and -1,4-xylanase were observed at 96 h of incubation [63]. Collectively, these indicated that the maximum activity of lignocellulose degrading enzymes could occur at different time point depends on different bacteria and/or lignocellulosic substrates.…”

The genus Meridianimaribacter is one of the least-studied genera within Cytophaga-Flavobacteria. To date, no genomic analysis of Meridianimaribacter has been reported. In this study, Meridianimar ibacter sp. strain CL38, a lignocellulose degrading halophile was isolated from mangrove soil. The genome of strain CL38 was sequenced and analyzed. The assembled genome contains 17 contigs with 3.33 Mbp, a GC content of 33.13% and a total of 2982 genes predicted. Lignocellulose degrading enzymes such as cellulases (GH3, 5, 9, 16, 74 and 144), xylanases (GH43 and CE4) and mannanases (GH5, 26, 27 and 130) are encoded in the genome. Furthermore, strain CL38 demonstrated its ability to decompose empty fruit bunch, a lignocellulosic waste residue arising from palm oil industry. The genome information coupled with experimental studies confirmed the ability of strain CL38 to degrade lignocellulosic biomass. Therefore, Meridianimar ibacter sp. strain CL38, with its halotolerance, could be useful for seawater based lignocellulosic biorefining.

“…Enzyme catalysis was specific, and different foods require specific enzymes for digestion and absorption by insects, and might adapt to dietary changes through the induction of enzyme production [ 23 ]. Different dietary characteristics may ultimately correspond to different gut microbial compositions [ 61 , 62 ]. In this study, we considered the correlation between feeding habits and the gut bacterial community of Ensifera to explore the dietary characteristics of the sample with contrasting feeding habits from the perspective of gut bacterial community.…”

Insect microbial symbioses play a critical role in insect lifecycle, and insect gut microbiome could be influenced by many factors. Studies have shown that host diet and taxonomy have a strong influence on insect gut microbial community. In this study, we performed sequencing of V3-V4 region of 16S rRNA gene to compare the composition and diversity of 12 Ensifera from 6 provinces of China. Moreover, the influences of feeding habits and taxonomic status of insects on their gut bacterial community were evaluated, which might provide reference for further application research. The results showed that Proteobacteria (45.66%), Firmicutes (34.25%) and Cyanobacteria (7.7%) were the predominant bacterial phyla in Ensifera. Moreover, the gut bacterial community composition of samples with different feeding habits was significantly different, which was irrespective of their taxa. The highest diversity of gut bacteria was found in the omnivorous Ensifera. Furthermore, common and unique bacteria with biomarkers were found based on the dietary characteristics of the samples. However, the bacterial community structure of the Ensifera samples was significantly different from that of Caelifera. Therefore, we concluded that feeding habits and taxonomic status jointly affect the gut bacterial community composition of the samples from Orthoptera. However, the influence of feeding habit dominates when taxonomy category below the suborder level. In addition, the dominant, common and unique bacterial community structure could be used to predict the contrastic feeding habits of insects belonging to Ensifera.

“…The genomic DNA was then extracted from the treated cells following the standard enzyme assisted cell disruption procedure followed by solvent extraction using PCI (Phenol:Chloroform:Isoamyl alcohol) in the ratio 25:24:1 and successive purification using ice-cold ethanol. The 16S rRNA gene was particularly amplified with the help of degenerative universal forward primer 27 F and reverse primer 1492R using hot-start PCR (Veriti 96-Well Thermal Cycler, Applied Biosystems, Thermo Fischer Scientific, Sin-gapore) [ 45 ]. The amplification of the gene was initiated primarily by denaturing the DNA at 95 °C for 5 min succeeded by 35 complete cycles of the denaturation, annealing, and elongation.…”
