Background and aims Many fruits soften during ripening, which is important commercially in rendering the fruit attractive to seed-dispersing animals. Cell-wall polysaccharide hydrolases may contribute softening, but sometimes appear be absent. An alternative hypothesis that hydroxyl radicals (•OH) non-enzymically cleave wall polysaccharides. We evaluated this by using a new fluorescent labelling procedure 'fingerprint' •OH-attacked Methods tagged polysaccharides with...
Kombucha is a traditional fermented drink and has recently gained popularity due to its numerous claims on therapeutic effects. It prepared by sweetening black tea using symbiotic culture of acetic acid bacteria yeasts known as SCOBY. The can also be brewed different type carbon sources. An investigation was conducted characterize the antioxidant antimicrobial properties kombucha variation sources: white sugar (S), jaggery (J) Kelulut honey (H) in (BT) green (GT) media over period 7, 14, 28...
Abstract Rice husk, an agricultural waste from the rice industry, can cause serious environmental pollution if not properly managed. However, husk ash (RHA) has been found to have many positive properties, making it a potential replacement for non-renewable peat in soilless planting. Thus, this study investigated impact of RHA composite substrate on growth, photosynthetic parameters, and fruit quality cucumber (Yuyi longxiang variety) melon (Yutian yangjiaomi variety). The RHA, peat,...
Previous study has shown the antimicrobial activities of mucus protein extracted from Anabas testudineus. In this study, we are interested in characterizing anticancer activity A. testudineus peptides (AMPs). The was extracted, fractioned, and subjected to antibacterial testing confirm fish's AMPs production. cytotoxic each fraction also identified. Fraction 2 (F2), which shows toxicity against MCF7 MDA-MB-231 were sent for peptide sequencing identify bioactive peptide. two then...
Hydroxyl radicals (•OH) cause non-enzymic scission of polysaccharides in diverse biological systems. Such reactions can be detrimental (e.g. causing rheumatic and arthritic diseases mammals) or beneficial promoting the softening ripening fruit, biomass saccharification). Here we present a method for documenting •OH action, based on fluorescent labelling oxo groups that are introduced as glycosulose residues when attacks polysaccharides. The was tested several polysaccharides, especially...
Xanthone is an organic compound mostly found in mangosteen pericarp and widely known for its anti-proliferating effect on cancer cells. In this study, we evaluated the effects of xanthone crude extract (XCE) α-mangostin (α-MG) normoxic hypoxic human hepatocellular carcinoma (HepG2) cells their toxicity towards zebrafish embryos. XCE was isolated using a mixture acetone water (80:20) verified via high performance liquid chromatography (HPLC). Both α-MG showed higher anti-proliferation HepG2...
Kombucha is one of the traditional fermented drink and known as health due to its claimed therapeutic efficacy. commonly prepared by sweetening black tea with white sugar using a bactocellulosic culture acetic acid bacteria yeasts. Ethanol production part fermentation process too much ethanol acids are harmful. Nowadays, alternative carbon sources different types teas also being used home brewers manufacturers but variation content respect change in medium less known. Therefore, this study...
Expansin is a cell wall loosening protein without hydrolytic activity, which allows expansion by influencing extensibility. Previous studies showed that the suppression of expansin genes (EXPA1, EXPA3, EXPA5 and EXPA10) resulted in defective organ growth altered chemical composition [1,2]. However, molecular mechanism on how non-enzymatic expression can result widespread effects plant still unclear. In this study, we performed transcriptomic analysis hypocotyls previously reported transgenic...
Anabas testudineus is a sturdy freshwater fish that can live in polluted environment due to the epidermal mucus (EM) protects from pathogens or germs. This study explored functional properties of EM as potential antimicrobial and anticancer agent. Inactive Pseudomonas aeruginosa was introduced into tanks stimulate production EM. stimulus significantly increased by more than 100% after 10 days stimulation, indicating influenced environmental biotic stress. In vitro antibacterial activity...
Cadmium (Cd) contamination of urban and agricultural soils is toxic to humans, animals may cause negative effects on plant growth crop production. The existing conventional methods are found be not efficient remove Cd from contaminated soil. present experiment reports the analysis nine T1 lines transgenic tobacco carrying metallothionein gene (eiMT1) Eleusine indica, with potential for high efficiency remediate in soils. Thirty-days old plants were treated different concentrations CdNO3 (0,...
Fish farmers’ dependence on costly formulated fish feed has affected their income. The cost of is also constantly rising. Efforts to mass-produce the locally available natural resource, namely water flea (Moina sp.), were initiated as an alternative commercially feed. This study evaluates most suitable growth medium for culturing Moina sp. and Chlorella studies effect activity quality. In this study, behaviour was monitored individually before cultured together with in a medium. different...

Recurrent and prolonged heat waves during summer have significantly impacted the growth quality of cultivated melons in China. Molybdenum (Mo), a trace element crucial for plant’s photosynthesis process under normal planting conditions, is posited to not only improve plant stress tolerance but also enhance fruit nutritional content. In this study, melon cv. ‘Japanese Sweet Treasure’ was used as experimental material. Various concentrations ammonium molybdate solution (0, 0.05, 0.1, 0.2, 0.4...
Kombucha tea has been claimed to have several health benefits. Many factors influence the properties of kombucha produced. This study focused on effects starter cultures (kombucha liquid broth (KLB) and cellulosic pellicle (KCP)) sweetener (white sugar (S), honey (H) jaggery (J)) used in production tea. The results showed that all teas prepared using KLB had a lower pH higher concentration acetic acid during fermentation. ethanol content for samples increased (0.7 ± 0.26 mg/L 1.73 0.58 mg/L)...
Expansin increases cell wall extensibility to allow loosening and expansion even in the absence of hydrolytic activity. Previous studies showed that excessive overexpression expansin gene resulted defective growth (Goh et al., 2014; Rochange 2001) [1,2] altered chemical composition (Zenoni 2011) [3]. However, molecular mechanism on how non-enzymatic protein can result widespread effects plant organ remains unclear. We acquired transcriptomic data previously reported transgenic Arabidopsis...
