Miang is an ethnic fermented tea leaf (Camellia sinensis var. assamica) from northern Thailand. It has a long history of sociocultural relationship with Thai people. Unlike other types tea, miang unique product that known as chewing or eating tea. In addition, it also specific food for traditional religious ceremonies and funerals. Although become less popular among younger generations, there remains demand in areas The fermentation mechanism not been well documented the information now...
Miang, a traditional fermented tea from Northern Thailand, potentially hosts beneficial probiotic bacteria. A total of 133 isolates lactic acid bacteria (LAB) isolated Miang were evaluated for potential. Among them, 5 strains showed high tolerance to bile and acidic conditions selected further evaluation. All inhibitory activity against human pathogens, including Bacillus cereus, Staphylococcus aureus, Salmonella ser. Typhimurium. Nucleotide sequences analysis the 16S rRNA gene revealed that...
Abstract Background Yeast treatment has been used for purification of fructooligosaccharides (FOSs). However, the main drawback this approach is that yeast can only partially remove sucrose from crude FOSs. The objective research was to screen strains capability selectively consuming unwanted sugars, namely fructose, glucose, and sucrose, in FOSs extracted red onion ( Allium cepa var. viviparum ) with minimal effect on FOS content. Results Among 43 species isolated Miang, ethnic fermented...
This study investigated the potential of microbial fermentative transforming processes in valorizing cashew apple by-product into a low-alcohol, health-benefiting beverage. We particularly use non-
Abstract Background Gallic acid has received a significant amount of interest for its biological properties. Thus, there have been recent attempts to apply this substance in various industries and particular the feed industry. As opposed yeasts, fungi bacteria their tannases well documented potential bioconversion specifically biotransformation tannic gallic acid. In research, Sporidiobolus ruineniae A45.2 is introduced as newly pigment-producing tannase-producing yeast that gained great use...
This study aims to utilize the microbial resources found within Laphet-so, a traditional fermented tea in Myanmar. A total of 18 isolates thermotolerant yeasts were obtained from eight samples Laphet-so collected southern Shan state, All demonstrated tannin tolerance, and six resistant 5% (w/v) concentration. capable carboxy-methyl cellulose (CMC) degrading, but only isolate DK showed ethanol production at 45 °C noticed by gas formation. producing yeast was identified be Cyberlindnera...
Barley malt residue (BMR) was subjected to microwave-assisted enzymatic hydrolysis evaluate its potential as a raw material produce xylooligosaccharides (XOS) suitable for use prebiotic. The influent factors on XOS production, microwave power, exposure time, and xylanase dosage were ascertained with response surface methodology based Box–Behnken design (BBD). fitted models of xylose yields in good agreement the experimental results. Using power 1235.1 W, 6 min concentration 89.12 U/g...
Xylooligosaccharides (XOSs) are produced from xylan, which is a component of the hemicellulose that can be found in bamboo shoots. Naw Mai Dong, an ethnic pickled shoot product northern Thailand, generally characterized as acidic and has sour taste. It considered potential source probiotic lactic acid bacteria (LAB). This study aimed to isolate efficient XOSs-fermenting LAB products. A total 51 were recovered 24 samples while 17 strains exhibited luxuriant growth xylose XOSs. Among these,...
The aims of this research were to optimize the ultrasonic-assisted enzymatic extraction polyphenols under Miang and tannase treatment conditions for improvement antioxidant activity extracts via response surface methodology. treated with without investigated their inhibitory effects on digestive enzymes. optimal highest total polyphenol (TP) (136.91 mg GAE/g dw) flavonoid (TF) (5.38 QE/g contents as follows: 1 U/g cellulase, xylanase, pectinase, temperature (74 °C), time (45 min). extract...
This study demonstrated the bioconversion of lignocellulosic by-product corn stover (CS) to value-added fermentative product L-lactic acid using furfural tolerant Enterococcus mundtii WX1 and Lactobacillus rhamnosus SCJ9. The efficacy dilute pretreatment by sulfuric formic acids varying from 1% 4% (v/v) concentration was compared. CS pretreated with selected for L-LA fermentation regarding highest fermentable sugar release when combined enzymatic hydrolysis process. Optimal conditions...
At present, few yeast species have been evaluated for their beneficial capabilities as probiotics. Sporidiobolus ruineniae A45.2, a carotenoid-producing yeast, was able to co-produce cell-associated tannase (CAT), gallic acid and viable cells with antioxidant activity when grown in tannic substrate. The aim of this research study identify the potential uses S. A45.2 obtained from co-production system feed additive aquaculture. its CAT displayed high tolerance pH 2.0, pepsin, bile salts...
Red onion is a popular ingredient in many Thai dishes and has recently been promoted for commercial cultivation. In this study, inulin-fructooligosaccharides (inulin-FOSs) were extracted from red onions simplified extraction method. The extract contained 24.00 ± 0.38 g/L free glucose, fructose sucrose, while the level of FOSs was recorded at 74.0 2.80 with degree polymerization 4.1. resistant to simulated gastrointestinal conditions, selectively promoting probiotic lactobacilli. These...
The study investigated the impact of fermentation process on phenolic contents and antioxidant anti-inflammatory activities in extracts Miang, an ethnic fermented tea product northern Thailand. acetone (80%) extraction Miang samples by a non-filamentous fungi-based (NFP) filamentous (FFP) had elevated levels total polyphenols, tannins, condensed tannins compared to young mature leaves. studies also showed better half-maximal inhibitory concentration (IC50) values for leaves both...
As has been confirmed in our previous study, red onion is a promising source of inulin-fructan, inulin neoseries fructan, and their fructooligosaccharides (FOSs). Short-chain FOSs (SCFOSs) are potential prebiotics as they provide many health promoting benefits. However, short-chain oligosaccharides isolated from plants have scarcely studied. After prebiotic production, purification step essential to produce functional prebiotic. The aim this study was develop new processes integrated...
Our recent research study focused on Miang fermentation revealed that tannin-tolerant yeasts and bacteria play vital roles in the production process. A high proportion of yeast species are associated with plants, insects, or both, nectar is one unexplored sources biodiversity. Therefore, this aimed to isolate identify tea flowers Camellia sinensis var. assamica investigate their tannin tolerance, which a property essential processes. total 82 were recovered from 53 flower samples Northern...
This study evaluated the effect of endophytic bacterium inoculation on sprouts and microgreens growth common buckwheat.The endophtyic isolate ST-B2, isolated from buckwheat seedling stems was identified to be Herbaspirillum sp.based analysis partial nucleotide sequence 16S rRNA gene.Inoculation bacterial strain ST-B2 markedly enhanced microgreens.The highest seed with endophyte found in treatment 20% (v/v) inoculum (2.0×10 -7 cfu.mL -1 ) while 10% (1.0×10 had microgreens.Inoculated at 25°C...
