The main plots included applying two compost manure levels before planting (24 and 48 m3/hectare). Subplots included cultivating five basil varieties (local and four foreign varieties: lime basil, smuglyanka basil, purple basil, and purple ruffles basil). The results revealed that applying compost manure at the highest level significantly increased herb and oil yield attributes over the lowest level. The evaluation of varieties showed that the purple ruffles and purple varieties were the most tolerant to abiotic stresses and recorded the significantly maximum herbage and oil yield. The essential oil chemical composition was affected by the interaction within treatments and harvest time. Applying 48 m3 compost/hectare and cultivation of foreign purple variety should be recommended in this region to produce the best yield quantity and quality characteristics (oil of high linalool of 50.95%–75.01% and minimum estragole of 0.00%–0.02%, as well as attractive flavor and color) which could promote exports.","PeriodicalId":15032,"journal":{"name":"Journal of Applied Biology and Biotechnology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84773642","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}

Of the structural proteins of the virus, the Spike (S) protein on the virion envelope binds to the host cell ACE2 through viral epitopes in the receptor-binding domain (RBD). Deletions in the ORF8 as well as mutations in the S gene of SARS-CoV of 2003 were related to adaptation of the virus to humans. The emergence of novel variants of SARS-CoV-2, viz., B.1.1.7, B.1.427 and B.1.429, B.1.617 and its Kappa and Delta strains/ variants, B.1.351, and P.1 in the United Kingdom, Americas, India, South Africa and Brazil, respectively, has been found be associated with the current waves of the COVID-19 pandemic. These variants are antigenically dissimilar, whereas the current COVID-19 vaccines are monovalent. This is a handicap in the control program. The Delta variant has been reported in 74 countries as of 14 June 2021 and the anticipated third wave involving this variant is of concern to the countries (www.gavi.org). Of late, on 17 June 2021, Delta Plus variant was identified in India (AIIMS, Bhopal, India). Circulation of virus in vaccinated population may lead to endemicity, and this can be monitored by regular serosurveillance for antibodies against select non-structural proteins (NSPs) of the virus;antibodies to NSPs will indicate virus replication in the host. Endemic areas will have higher NSP reactors. It is predicted that the Delta B.1 variant may ignite the third wave of the disease in many countries. As it has been difficult to achieve uniformity in time and density of the vaccination even in the districts, circulation of the virus in partially immune population may lead to the selection of newer variants of SARS-CoV-2. The presence of monoclonal antibody resistant mutants and neutralization—escape mutants in quasispecies structure of another + sense RNA virus, i.e., Aphthovirus (FMD virus;foot and mouth disease virus) in the family Picornaviridae is well documented. The situation could be similar in the Coronaviridae member SARS-CoV-2. Previous immunity may not protect against current/ future mutants thereby pro-longing the COVID-19 control Programme. © 2022 Sharanagouda S.

Fourteen selective TBT-resistant isolates showed cross-tolerance to heavy metals and antibiotics. Among them, one interesting isolate VBAK, showing the highest TBT resistance and maximum growth yield, was selected and taxonomic identification was carried out by sequencing 16S rRNA gene. The maximum composite likelihood algorithm formed a coherent cluster with clad comprised Pseudomonas sp. The thin-layer chromatography profile of the degradation product revealed the depletion of TBT into dibutyltin. The Rf values of TBT and transformed compounds were 0.8 (solvent front = 16.5 ± 2, TBT 9.1 ± 1.0) and 0.7 (solvent front = 6.5 ± 2, product 6.8 ± 2), respectively.

The peptide of interest was partially identified and checked for anti-cancer activity using MDA-MB-231 triple negative breast cancer cell line. To begin with, it was purified via ammonium sulfate precipitation, ultrafiltration, and gel filtration chromatography. It was partially identified using mass matrix assisted laser desorption/ ionization-mass spectrometry (MS-MALDI) and checked for cytotoxic activity using (3-(4,5-Dimethylthiazol2-yl)-2,5-Diphenyltetrazolium Bromide) assay. As an outcome, the active part collected after ultra-filtration, 880 μg/ml of protein content with 15 mm zone diameter, was loaded on sephadexG50 column. The purified protein content was found to be 118 μg/ml with 15 mm of zone of inhibition against Listeria monocytogenes. A peak was obtained at a retention time of 9.371 minutes on subjected to high performance liquid chromatography. The result of MS-MALDI revealed it as an unnamed peptide with 75% query sequence similarity with the hypothetical protein of Lactobacillus reuteri. The cytotoxic study revealed its potential as an anti-cancer peptide, with the IC50 value of 108 μg/ml for MDA-MB-231 cancer cell line. In conclusion, this is the first report of this unknown peptide which showed both antibacterial and cytotoxic activity. It may act as a promising agent and can be further explored in future.","PeriodicalId":15032,"journal":{"name":"Journal of Applied Biology and Biotechnology","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89162358","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}

Maximum biosorption of hexavalent chromium was observed at pH 3.5 with adsorbent dose 2.5 g at 30°C. Three days were considered as the optimum exposure period for chromium removal for live biomass, whereas 1.3 hours exposure period for dead biomass of A. flavus. The equilibrium data were examined by Langmuir and Freundlich isotherms. Freundlich isotherm appeared to be the best fit model. Phytotoxicity test was conducted to check the effect of the treated chromium solution on the seed germination, seedling length, and vigor index of Vigna radiata. Only 23% germination was reported in chromium metal-treated V. radiata seeds, but germination and growth parameters of mung bean seeds were significantly increased in the chromium solution after treatment with dead and live biomass. The chromium biosorption potential showed the following trend: dead A. flavus > live A. flavus. Hence, live and dead biomass of A. flavus can be applied as a safe and economically feasible biosorbent for hexavalent chromium elimination for the treatment of industrial effluent or wastewater system.","PeriodicalId":15032,"journal":{"name":"Journal of Applied Biology and Biotechnology","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88438196","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}
