Geranylgeranyl diphosphate synthase (GGPPS) is the crucial bottleneck in carotenoid biosynthesis. However, low activity limits broad application of GGPPS. In this study, OsGGPPS1 rice was engineered based on ancestral sequence reconstruction (ASR) and semirational design to improve catalytic performances existing The better mutant A22R/A26P with improved enzyme generated ASR. Additionally, mutants as V162A/M218S/F227Y designed using a design. combinatorial assembly d-OsGGPPS1...
Fatty acid ethyl esters (FAEE) are key target for wine industry to diversify its production towards fruity flavor. The microbial community and functional enzymes governing FAEE formation during Chinese rice (Huangjiu) brewing were investigated in current study. Physicochemical characteristics displayed distinct phased changes, which fluctuated sharply initial fermentation then leveling off gently. Except reducing sugar, other factors showed strong positive correlations with the dominant...
Lotus roots (Nelumbo nucifera Gaertn.) are rich in nutrients and have ornamental food value. However, browning has caused huge economic losses security risks during the storage harvesting of fresh-cut lotus. This study investigated role melatonin inhibiting lotus browning, illustrates its molecular mechanism.The application effectively retarded process enhanced reactive oxygen species (ROS) scavenging enzyme activity, inhibited activity polyphenol oxidase (PPO), peroxidase (POD). Melatonin...
An alginate lyase encoding gene sagl from Flavobacterium sp. H63 was codon optimized and recombinantly expressed at high level in P.pastoris through cell-density fermentation. The highest yield of recombinant enzyme (rSAGL) yeast culture supernatant reached 226.4 μg/mL (915.5 U/mL). This the record expression so far. rSAGL confirmed as a partially glycosylated protein EndoH digestion. optimal reaction temperature pH this were 45 °C 7.5; 80 mM K+ ions could improve catalytic activity by 244%...
The effect of temperature fluctuations on the freshness shrimp in simulated trays was investigated by setting a freeze–thaw (F-T) cycle 12 h after freezing at −20 °C and thawing 1 under refrigeration. results showed that shrimp’s physicochemical properties deteriorated to different extents with increase F-T cycles. total colony count 6.07 lg CFU/g 21 cycles, volatile saline nitrogen content reached 30.36 mg/100 g, which exceeded edible standard. In addition, sensory quality textural...
Selenium (Se) is an essential trace element that plays a critical role in human tissue formation, metabolism, and physiological functions. However, many individuals worldwide suffer from Se deficiency diseases. This study aims to evaluate the impact of Se-tolerant LF-17 agents exogenous Na2SeO3 application on growth, enzyme activity, metabolic characteristics rape seedlings. Treatment LF-3 (inoculation agent Na2SeO3, with soil concentration 5 mg/kg) led 38.62% increase plant height 116.7%...
Abstract In this study, a mixed strain ( MS ) starter culture was prepared by fed batch fermentation method and its effect on wheat dough steamed bread quality investigated. The had higher leavening ability more viable yeast counts than traditional TMS made static method. A slight decrease observed in the extensibility of fermented yeast, as resting time increased. leavened that but similar to during overall fermenting process. No significant differences could be between resistance extension...

During Streptococcus zooepidemicus fermentation, most carbon sources are used to synthesize lactic acid, which can inhibit strain growth and hyaluronic acid production. Here, we expressed bacterial haemoglobin (Vhb) in Strep. zooepidemicus. Due highly efficient oxygen use, only 15·26 g l−1 was produced, is 0·73 times the quantity produced by control strain. Compared with (1·61 l−1), (HA) production this did not substantially increase, 2·16 l−1. Next, a series of...
Agricultural soil contamination by pesticide residues has become a serious issue of increasing concern due to their high persistence and toxicity non-target species. However, as the world's largest peach producer, national scale surveys on in orchard soils are scarce China. In this study, target suspect screening method covering over 200 pesticides commonly used orchards was developed using ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry...
Corn straw is considered a renewable biomass energy source, and its unreasonable disposal leads to resource waste environmental pollution. Black soldier fly (Hermetia illucens L.) larvae (BSFL) facilitate the bioconversion of various types organic wastes. In this study, we found that 88% BSFL survived, 37.4% corn was digested after 14 days feeding with straw. Contrary expectations, pretreatment alkaline hydrogen peroxide did not promote digestion but rather reduced growth survival rates...
A novel actinobacterial strain, 3-wff-81(T), was isolated from interfacial sediment of the eutrophic Taihu Lake in Jiangsu Province (China) and subjected to polyphasic taxonomic characterization. The strain formed pale orange-pigmented colonies comprising rod-shaped cells on R2A agar. Phylogenetic analysis based 16S rRNA gene sequences showed that 3-wff-81(T) belonged genus Geodermatophilus, with Geodermatophilus soli PB34(T) (99.1 % similarity) terrae PB261(T) (98.3 as closest relatives....
This study investigated the effect of Lactobacillus plantarum DM616 on dough fermentation for making Chinese steamed bread. Dough was carried out via inoculation with Saccharomyces cerevisiae as monoculture, or in combination L. co-culture. The presence caused faster depletion reducing sugars and had little maximum specific growth rate (μmax) final cfu/g sourdough S. cerevisiae. In co-culture, pH varied from 3.2 to 3.5 total titratable acids developed 9.2 after 24 h fermentation. did not...
An aerobic, motile, Gram-stain-negative bacterium, designated strain NS1T, was isolated from interfacial sediment Taihu Lake, China. The formed yellow colonies on R2A medium. Cells were ovoid to rod-shaped and non-spore-forming. Growth occurred at 15-40 °C (optimum, 28 °C), pH 5.0-10.5 6.5-7.5) in the presence of 0-1 % (w/v) NaCl 0 %). Phylogenetic trees based 16S rRNA gene sequences showed that NS1T represented a member genus Altererythrobacter had highest sequence similarity troitsensis...
