The hemicellulose components (15 - 20 %) of banana fiber can be a feedstock for producing high-value commodity chemicals. Hemicellulose is extracted by physical, chemical, and biological methods, in which combining hydrothermal treatment with alkaline mode of extraction provides an enhanced recovery percentage. Thus, the present study aimed to optimize the hydrothermal-assisted alkaline method of xylan extraction from the banana fiber biomass. Initially, xylan was extracted with a conventional-based alkali method. A maximum of about 43 and 35 % was recovered from pretreated and raw banana fiber at 12% NaOH concentration when incubated at 55 °C for 24 h. To improve the xylan yield, the hydrothermal assisted alkali method experimented in which 67.1% and 58.3 % of xylan were recovered when treated at 121 °C for 1 h at 12% NaOH. To further enhance the xylan recovery, a two-step alkali process by combining conventional and hydrothermal-assisted alkali methods resulted in the highest xylan (81%) recovery from pretreated banana fiber when incubated with 12 % alkali for 8 h followed by steam treatment. On the other hand, a maximum of 73 % of xylan was recovered when steam treated after incubation for 24 h from raw banana fiber. Thus, the alkali incubation followed by steam treatment significantly showed the highest xylan recovery from the banana fiber biomass. The extracted xylan might be utilized as a source for various xylan-based products, including furfural, xylooligosaccharides, xylose, and xylitol, all of which have significant roles in the pharmaceutical and food industries.","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Documentation on morphological traits is quite informative in tomato breeding programs since higher levels of diversity on morphological traits are associated with genotypes with lower genetic diversity when assessed using molecular markers. The present investigation aimed to evaluate morphological diversity in tomato germplasm accessions. Morphological characterization was performed in 104 genotypes acquired from various sources. Thirty-three morphological traits, such as seedling, plant, inflorescence and fruit, were scored based on the tomato descriptors. Out of 33 characters studied, 26 traits exhibited diverse modalities, 4 traits exhibited varied classes in genotypes and 3 traits did not show any variants. Qualitative characterization highlighted greater variability among genotypes, as witnessed by their diverse modalities for each trait. The collected data was subjected to Agglomerative Hierarchical Clustering following Ward’s method. Cluster analysis and dendrogram construction displayed genetic diversity's richness in the germplasm accessions. Cluster analysis placed these 104 genotypes in six clusters. The largest cluster comprised 55 genotypes, whereas the smallest cluster had three. Agglomerative Hierarchical Clustering helped to find similarities between genotypes. This efficiently assigned genotypes into groups and thus provided guidelines for parental selection in tomato hybridization and breeding programmes.","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of hydrolase, phytase can alleviate this problem but is hindered by its cost. The goal of the current study is to clone, express and purify the phytase gene from Bacillus sp. (DS11) into Schizochytrium sp. ATCC 20888 is also a good producer of Docosahexaenoic acid (DHA). This is expected to enhance animal nutrition and reduce phosphate pollution. The DNA sequence analysis using multiple sequence alignments showed significant similarity to the phytase gene from Bacillus sp. (DS11). Subsequently, specific primers were designed based on the consensus sequence of the Bacillus phytase gene obtained from sequencing. The coding DNA sequence was determined to have a length of 1152 base pairs. Phytase gene was successfully cloned into the pRI201-AN DNA vector and transformed into Schyzochytrium sp. Screening on G418 plates showed 53 resistant colonies and from this 11 prominent colonies were chosen for further testing. Out of this, 8 colonies tested positive, with colony PCR having 1.5 kb with a phytase activity of 1.77 U/ml of crude lysate. Further purification with Ni-NTA affinity chromatography provided a specific activity of 15.59 U/mg. This appears to be the first ever reported recombinant phytase produced in Schizochytrium sp. The phytase recommendations are 250U/Kg of feed preparation for broiler & swine diets . It was also determined that 72.64 U/5.2 gm of wet biomass and 1.80% of w/w microalgae would fulfil these requirements per kg of feed preparation.","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135109791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this practice is costly and environmentally hazardous. Sustainable increase in crop yield can be achieved through alternatives like microbial-based fertilizers. In the quest to identify plant growth-promoting endophytic bacteria, the present study was carried out and selected unexplored halophytic plant Heliotropium curassavicum L. Thirteen endophytic bacterial strains were isolated from both aerial and root portions of H.curassavicum. These isolates were tested for salt tolerance, enzyme production, and synthesis of growth-promoting secondary metabolites, like Indole-3-acetic acid (IAA) and phosphate solubilization . Most of the isolates belonged to the Bacillus family, exhibiting varying Gram staining and biochemical reactions. The majority are Gram-positive bacteria, non-motile, spore formers, and exist in two cells or chains. All isolates could tolerate up to 10% NaCl concentration and a temperature of 42°C. Based on phenotypic, bio-chemical characteristics, isolate HCR3 showed promising properties in synthesizing IAA and phosphate solubilization abilities. The isolate HCR3 grew well upto 10% NaCl concentration and also 42°C temperature. Based on molecular characterization by using 16S rRNA gene-based analysis HCR3 isolate was identified and belonged to the Genus Pseudomonas with the highest similarity index with Pseudomonas khazarica sp. HCR3 showed IAA production of 37µg ml-1, had a phosphate solubilization ability of 3.5 ppm, and recorded protease activity on gelatin medium.

In the present study, twenty-four male Wistar albino rats were separated into three groups of eight animals each, including rats adult aged (6 months), and old-aged (24 months old). The elderly resveratrol-treated group was administered 25 mg/kg/day of resveratrol diluted in distilled water orally via gastric tube. The treatment lasted three months. At the end of the experiment, blood was drawn for serum creatinine analysis, the animals were sacrificed, and the kidneys were removed and processed for histological investigation. The findings revealed variable changes in kidney tissue, including glomerulosclerosis, compensatory glomerular hypertrophy, tubulointerstitial fibrosis, thickened glomerular basement membrane, arterial sclerosis, tubular dilatation with cast formation, atrophy of the tubules, infiltration of inflammatory cells, a rise in the rate of apoptotic cells, and a decrease in the glomerular number. These histological changes were associated with increased serum creatinine levels and kidney malondialdehyde (MDA), a marker of lipid peroxidation. The use of RES (Resveratrol) improved the creatinine level with a decrease in the MDA and improved the histological changes of aged kidney. As a result, the progression of aging was accompanied by different histological variations that interfered with the physiological functioning of the kidney, predisposing older persons to renal illnesses. Utilizing RES as a prophylactic and/or therapeutic medicine for aging-related renal changes is also possible.","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
