Preservation Study for Raw Conditioned Mutton During Refrigerated Storage by Food Preservatives.

The quality modification of chilled, raw conditioned mutton (RCM) after storage significantly impacts consumer preferences, making shelf-life extension and quality preservation crucial. This study evaluated the effects of sodium diacetate (SDA), sodium dehydroacetate (DHA-S), ε-polylysine hydrochloride (PLH), and nisin on RCM quality and bacterial community at concentrations of 3.0, 0.

Effects of Fermentation with on Sensory Properties and Flavor Compounds of Mulberry Leaf Tea.

Mulberry leaf tea (MT) is a popular Chinese food with nutrition and medicinal functions. Solid-state fermentation with of MT (FMT) can improve their quality. Differences in chromaticity, taste properties, and flavor characteristics were analyzed to evaluate the improvements of the sensory quality of FMT.

Light calcium carbonate improves pullulan biosynthesis by Aureobasidium pullulans under high concentration of sugar.

The effects of light calcium carbonate (CaCO) on pullulan biosynthesis by Aureobasidium pullulans NCPS2016 were investigated. Light CaCO enhanced pullulan production by 12.4 % when added to the low concentration of fructose broth compared with KHPO.

High-level production of pullulan from high concentration of glucose by mutagenesis and adaptive laboratory evolution of Aureobasidium pullulans.

The cost of carbon sources and the low efficiency of the fermentation titer limit the industrial application of pullulan. In this study, a hypertonic-tolerant strain with efficient utilization of glucose was obtained using a double strategy. Initially, a strain for efficient synthesis of pullulan from glucose was generated by mutagenesis.

Identification of Lipopeptide Iturin A Produced by NCPSJ7 and Its Antifungal Activities against f. sp. .

NCPSJ7 showed potential fungicidal activities for the effective control of fungal infection. From the PCR test, the key genes (, , , , , and ) were detected in NCPSJ7. These genes were closely related to the lipopeptides (LPs) synthesis.

Evaluation of the Efficacy of Enterococcus faecium L3 as a Feed Probiotic Additive in Chicken.

The study was devoted to the comparison of the probiotic effect of enterococcal Enterococcus faecium L3 to the antibiotic enramycin as a chicken feed additive. Two hundred and sixteen chickens were divided into three groups and tested by different parameters including weight gain, food consumption, blood biochemistry, immunology, and caecal microbiome at two checkpoints, 21 and 39 days after birth. By the end of the experiment, a group of chickens getting probiotic demonstrated weight gain of more than 100 g at the average relative to the control group with no additive in animal feed (P < 0.

Application of antagonist NCPSJ7 against in postharvest Red Globe grapes.

We investigated the effects and possible mechanisms of NCPSJ7 against the gray mold caused by in the postharvest Red Globe grapes. The disease incidence, lesion diameter, decay index, and some resistance-related enzymes were evaluated. The antioxidant capacity of grape treated with 1 × 10 CFU/ml alone and combined with 1 × 10 CFU/ml NCPSJ7 was also determined.

Melanin biosynthesis in the desert-derived Aureobasidium melanogenum XJ5-1 is controlled mainly by the CWI signal pathway via a transcriptional activator Cmr1.

The melanin produced by Aureobasidium melanogenum XJ5-1 obtained from the Taklimakan Desert can play an important role in adaptation of the yeast strain to various stress treatments. It is very important to know how the desert-derived yeast sense, respond and adapt to the harsh environments. However, it is still unclear how melanin is genetically controlled by signaling pathways and transcriptional factors.

Statistical Optimization of Medium for Pullulan Production by NCPS2016 Using Fructose and Soybean Meal Hydrolysates.

Pullulan, with its excellent characteristics of film-forming, water solubility, and biodegradability, is attracting more and more attention in agricultural products preservation. However, high pullulan production cost largely restricts its widely application due to its low production. In order to improve pullulan production by NCPS2016, the medium was optimized using single factor experiment and response surface methodology.

A highly Conserved Aspartic Acid Residue of the Chitosanase from Bacillus Sp. TS Is Involved in the Substrate Binding.

The chitosanase from Bacillus sp. TS (CsnTS) is an enzyme belonging to the glycoside hydrolase family 8. The sequence of CsnTS shares 98 % identity with the chitosanase from Bacillus sp.

Extracellular overexpression of chitosanase from Bacillus sp. TS in Escherichia coli.

The chitosanase gene from a Bacillus sp. strain isolated from soil in East China was cloned and expressed in Escherichia coli. The gene had 1224 nucleotides and encoded a mature protein of 407 amino acid residues.
