The bark extract of Michelia champaca could inhibit the growth of the fungi. The present research aimed to know the active compound responsible for antifungal activity. Extraction was done using the Maceration method, antifungal activity was measured using the Diffusion well method, and identification of active compounds was carried out using Gas chromatography-mass spectroscopy (GC-MS). The methanol extract obtained had a yield of 18.7%. It showed strong activity against C. verruculosa with an inhibition zone until 30.01 mm. The fractionation results showed that n-hexane extract (HE) was the strongest inhibiting the growth of C. verruculosa (32.45 mm), followed by chloroform extract (CE) (29.20 mm), while n-butanol extract (BE) was not active. Separating active compounds from HE extract was made using Column chromatography (CC) method with silica gel as the stationary phase and the mixture of n-hexane-acetone (3:1) as the mobile phase. This separation resulted in 5 combined fractions; HE3 and HE5 extracts showed very strong activity against C. verruculosa, with a diameter of the inhibition zone of 26.73 and 33.46 mm, respectively; HE2 extract showed strong activity with a diameter of the inhibition zone of 15.21 mm, while HE1 and HE4 extracts did not show activity. Identification using GC-MS, especially the HE3 extract, revealed that the extract contained two compounds: tributyl acetyl citrate and terephthalic acid, dodecyl-2-ethylhexyl ester.

Its pathogenesis is linked to numerous virulence factors. Understanding these factors and exploring alternative options for the use of antibiotics in the treatment of this bacterium, molecular techniques offer several advantages over traditional culture techniques because they are easier and more specific. The present study aimed to use specific primers for the 16sRNA and LuxR genes to identify B. fragilis. Genetic identification of the B. fragilis isolates was performed using the 16SrRNA gene, and the obtained sequences were submitted to National Centre for Biotechnology Information (NCBI) with accession numbers (OQ448827, OQ448828). Each strain was assigned a unique strain name, AS. AWB94 and AS. AWB79. From the total of all samples, it was found that the growth of various types of bacteria constituted ( 76%), and the samples that did not have growth formed (24%). It was noted that Bacteroidetes constituted only two isolates (2.7%), and these two isolates possessed the gene for quorum sensing (luxR gene), while the results confirmed that they do not possess the sialidase (nanH) enzyme gene. Both isolates possessed the quorum sensing gene (LuxR) out of one hundred samples. This suggests that the isolates have a quorum-sensing mechanism responsible for cell-to-cell communication, multidrug resistance, and biofilm formation.\u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388661","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}

These parameters included slope, texture, calcium carbonate, sum of basic cations, pH, organic matter, salinity, exchangeable sodium percentage and mean temp. of the growing cycle. The rated parameters were processed according to the AHP. The results were compared with Storie and the Square root methods and field observations. When validated using field observations, the developed method had a higher accuracy suitability evaluation for wheat cultivation in the studied area than the other two methods. According to the developed method, almost all of the studied areas could be classified as very suitable (S1) for wheat cultivation. On the other hand, the wheat suitability evaluation according to the other two methods indicated that most of the studied area could be classified as moderately suitable (S2) and marginally suitable (S3), which contradicted the field survey.\u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388391","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}

Field experiments were laid out with the treatments viz., CuSO4,, (5kg/ha) (T1), Gypsum (500 kg/ha) (T2), Conoweeding+Alternate Wetting and Drying Irrigation(AWDI) (T3), microbial consortia (K and Zn solubilising Bacteria 500 ml/ha) (T4) control (T5) and combination of all (T6) except CuSO4 along with control . The results indicated that the T6 recorded higher plant height (110.2 cm), productive tillers/m2 of 332, filled grains of 118.3 and less chaffy grains of 20.3 nos, high nutrient status of 265 kg/ha of available N,35.4 kg/ha of available P,342 kg/ha of available K, 21.1meq/100 g of Ca,8.2 meq/100 g of Mg and root length and volume. The algal population in terms of dry biomass was reduced to 3.1 (g/m2) from the control group of 11.2 (g/m2) at 15 days after imposing treatment. The per cent increase of 26.0 % grain yield was also recorded in the combination treatment over control. From the present research, combined application of gypsum @500 kg/ha +Cono weeding twice +AWDI and microbial consortia of Zn and K solubilising bacteria @500ml/ha could be recommended for better soil environment and rice production in the delta region.\u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388634","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}
