The aim of the study was to purify and characterize crude amylase from probiotic Lactobacillus plantarum CS for its industrial applications Three purification steps including ammonium sulphate precipitation, ion exchange chromatography on carboxymethyl sephadex and gel filtration on Sephadex G-75 were utilized. The homogeneity of the purified enzyme was confirmed using sodium deodocyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The purified amylase was characterized on different parameters including substrates hydrolyses, pH and temperature activity and stability profiles. The general purification elution profile revealed two different peaks of amylase activities with outstanding one having a molecular weight of 59.7kDa. Its purification fold was 4.0 with specific activity of 16.44U/mg protein and enzyme yield of 3%.  Temperature optimal activity and stability was at 400C and 7.5 for pH activity and stability. Mangenese (Mn2+) (135.17%), tween 80 (128.30%) and some food condiments garlic, thyme, ginger, and tumeric) significantly (p> 0.05) enhanced amylase activity (≥262.40%). However, selenium (Se4+) and hydrogen peroxide (H2O2) were observed to have greatest inhibiting effect (≥30.9%) on the enzyme. Substrate hydrolysis profiles showed that the amylase hydrolyzed all the test starchy substrates with the highest hydrolytic potential on indigenous sweet potato starch (Km value/ Vmax of 1.33mg/ml/ 7.89ml).

Numerous bioactive substances can be found in food components, such as nutritional elements like proteins, carbs, vitamins, minerals, antioxidants, phenolics, and flavonoids, as well as primary and secondary metabolites. Functional foods have a greater importance for their health benefits above and beyond basic nutritional requirements. Demand for functional foods is rising as individuals become more conscious of how their diet affects their health. Prebiotics are short-chain carbohydrates that promotes the growth of healthy bacteria, are converted into fatty acids in the colon, and help the body absorb calcium and magnesium. Intestinal cancer risk is also reduced by them. However, animal products also include useful components such bioactive peptides, conjugated linolenic acid, long-chain omega-3, -6, and -9 polyunsaturated fatty acids, probiotics, and prebiotics.

A total of 120 adult pigeons (Columba livia domestica) were used in the study and kept in wooden cages, and all pigeons received the same quantity of (22%) crude protein and water during trials. Pigeons were acclimatized for 15 days and divided into four equal (A, B, C and D) groups, each consisting of 30 birds. Test groups (B-D) were exposed to CPF with oral doses of “1.3 mg, 1.6 mg, and 2.1 mg/kg body weight/day” respectively for twelve successive weeks, whereas (group A) was assigned as a controlled group. At the end of the trials, blood samples from exposed and controlled group birds were obtained from brachial and collected with anticoagulant “K3-EDTA” vacutainer tubes for hematological assessments.

For scanning the efficacy of some selected processing treatments, the natural vegetation of Tharparkar (NVT) i.e., mung beans (MB), sesame seeds (SS), and pearl millet (PM), were sprouted, roasted, and blanched, respectively, and milled to flour after thermal drying.  All fresh and processed NVT, i.e., sprouted mung bean flour (SMBF), roasted sesame seed powder (RSSP), and blanched pearl millet flour (BPMF), were analyzed for proximate composition, profiling of amino acids (AAs), and safety assessment. The results demonstrated statistically different (P<0.05) mean values of fresh and processed NVT for most of the analyzed parameters. It was found that processing significantly increased (P<0.05) ash, protein, fat, and fiber content whereas significantly decreased (P<0.05) phytic and oxalic acid in the NVT. In addition, some essential AAs significantly (P<0.05) enhanced in SMBF i.e., histidine (0.45g/100g), isoleucine (0.59g/100g), lysine (0.71g/100), methionine (0.23g/100g), phenylalanine (1.54g/100g), and valine (0.32g/100g); RSSP i.e., isoleucine (1.63g/100g), leucine (4.57g/100g), lysine (0.75g/100g), phenylalanine (3.14g/100g), tryptophan (0.81g/100g), and tyrosine (2.15g/100g); and in BPMF i.e., threonine (0.55g/100g), isoleucine (0.28g/100g), leucine (1.70g/100g), methionine (0.21g/100), tryptophan (0.11g/100g), and valine(0.17g/100g). Among non-essential AAs, the alanine and glycine remained significantly higher (P<0.05) in all processed NVT i.e., 1.56, 1.29, and1.43g/100g alanine in SMBF, RSSP, and BPMF, respectively. However, glycine remained at 0.56, 0.59, and 0.23g/100g in SMBF, RSSP, and BPMF, respectively. It is therefore concluded that processing techniques exerted a significant role in enhancing nutritional profile while mitigating the antinutrient load from the NVT.

This essay looks at the ingredients, health advantages, and possibilities as a high-energy food source of potato pudding. The objective of this work was to develop and characterize a new pudding recipe using potato flour as the main ingredient. The recipe was formulated by varying the ratios of potato flour and milk powder and by adjusting the sugar levels. The resulting puddings were evaluated for their texture, nutritional composition and sensory characteristics. The findings showed that the potato flour and milk powder- based pudding had a creamy texture with a smooth mouthfeel. The sensory assessment revealed a non- significant (p < 0.05) difference between potato pudding and control, suggesting that potato pudding formulations have a high potential to substitute potato starch.","PeriodicalId":411068,"journal":{"name":"Pakistan Journal of Biotechnology","volume":"8 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140235419","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 two varieties Anmol and Long green were tested by applying six N rates that included (0 Kg N, (control), 50, 75 ,100, 125 and 150 Kg N ha-1). Both the varieties exhibited positive response to nitrogen fertilization. The maximum vine length, branches vine-1 were noted in plants, fertilized with increasing N rates (150 and 125 kg ha-1). In contrast shorter plants with less branches were noted when they were not fertilized with N nutrition.). The N nutrition also had a positive effect on fruit traits. The maximum fruit number with greater length and weight was recorded in plants supplied with increasing N fertilization. The N fertilization had beneficial influence on plant quality characteristics. The maximum pH, TSS, moisture and ash content in plants were observed, nourished with increasing N supply. The varietal comparison indicates that fruits of \"Long green\" had lower pH (5.88 vs. 6.0), higher in TSS (5.39 vs. 4.28%), moisture (67.74 vs. 55.52%), ash contents (19.96 vs. 19.01%), fruit yield (18178 vs. 17123 kg ha-1) than variety “Anmol”.

This study aimed to isolate, identify and characterize the tomato fungal pathogens in District Kamber Shahdadkot.

This fact supports the malaria prevention theory. The objective of this paper to determine whether and how much there is a protective relationship between malaria and G6PD deficiency. Twelve databases were searched for studies describing any G6PD connection in malaria patients. 38 of the 50 included papers qualified for the review. Results indicated that there was no harmful association between G6PD deficiency and uncomplicated falciparum malaria in Even though it puts carriers at risk for hemolysis, glucose-6-phosphate dehydrogenase (G6PD) deficiency is widespread in areas of Pakistan where malaria is also prevalent. This data supports the malaria protection hypothesis. Pakistan's annual malaria burden is estimated to be 1.5 million cases. The government needs to execute a successful malaria control and eradication program, given the prevailing circumstances. Destroying Plasmodium falciparum gametocytes and eradicating Plasmodium vivax hypnozoite reservoirs are possible with primaquine. However, when using this medication, those who lack the enzyme glucose-6-phosphate (G6PD) experience hemolysis. The distribution of malaria and G6PD deficiency in Pakistan must be mapped to create an effective medication to suppress the disease. No significant reports of G6PD deficiency (G6PDd) in malaria patients have come from Pakistan.
