Adsorption result showed that maximum uptake of 38.3, 31.0, 33.5 and 14.5 mg/g were respectively obtained for Bleached (BPKF), Acetylated (APKF), Mercerized (MPKF) and Unmodified Palm Kernel Fibers (UPKF) adsorbents at an optimum time of 3 hours. The sorption kinetic obeyed pseudo second order with the bleached adsorbent (BPKF) having the best fit, and at a certain time limit, intra-particle diffusion controlled the process. Data collected from effect of initial concentration experiments were better fit to the Freundlich isotherm. The result from the thermodynamics of the process showed an endothermic process. Increasing adsorbent dosages led to corresponding increase in the quantity of the indigo dye adsorbed by the different adsorbents. This work revealed the potentials of modified palm kernel fibers over the unmodified fiber for effective removal of Indigo blue dye from wastewater.","PeriodicalId":511647,"journal":{"name":"Lafia Journal of Scientific and Industrial Research","volume":" 414","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140092252","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}

Candida have been associated with diverse diseases including life threatening invasive, superficial and hematogenic infections. This study determined the prevalence of Candida species amongst unmarried women attending Lafia Primary Health Care Centers. Forty high vagina swabs were collected from unmarried women. Isolation and identification of Candida species were performed according to standard procedures using Sabouraud Dextrose Agar, Gram staining and Germ tube test. 13 (32.5%) were positive for five different Candida species. C. albicans was the most prevalent (38.46%; 5/13) species while non-albicans Candida [C. glabrata (23.07%; 3/13), C. tropicalis (6.89%; 2/13), C. parapsilosis (3.44%; 1/13) and C. krusei (6.89%; 2/13)] accounted for 61.54% (8/13) of the total positive cases. Women aged 15-18 years and 23-26 years had the lowest and highest prevalence rates of 14.28% (1/7) and 42.10% (8/19) respectively. Candidiasis is a threat to global health and should be taken with all seriousness. The high candidiasis prevalence observed herein portrays a concern and calls for a continuous study of unmarried women attending Primary Healthcare Centers in Lafia. Furthermore, there should be an improvement in creating awareness of the opportunistic pathogenic characteristic of Candida species as normal flora and the effect they cause when there are hormonal imbalances caused by drug abuse, pregnancy, and poor dieting. The practice of good hygiene should be observed to prevent the spread of the infection.","PeriodicalId":511647,"journal":{"name":"Lafia Journal of Scientific and Industrial Research","volume":"32 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140442132","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}

Phosphorus solubilizing bacteria (PSB) convert insoluble forms of phosphorus into soluble forms that can be taken up by plants. The study aimed to isolate and characterize PSB from the rhizosphere of millet plants in Lafia, and to evaluate their potential for improving soil fertility and crop productivity. Soil samples were collected from four different locations and plated on Pikovskaya's agar medium. PSB colonies were identified based on their ability to produce clear zones around them. The PSB isolates were further characterized by morphological, biochemical, and molecular methods. The phosphate solubilizing activity and plant growth-promoting traits of the PSB isolates were also assessed. The PSB isolates were tested for their effect on the growth of millet seedlings in pots. The results showed that 16 PSB isolates belonging to four genera (Bacillus, Pseudomonas, Enterobacter, and Klebsiella) were obtained from the soil samples. The PSB isolates exhibited varying degrees of phosphate solubilizing activity, ranging from 11.2 to 81.6 mg/L. The PSB isolates also showed positive results for the production of indole acetic acid, ammonia, hydrogen-cyanide, and siderophore. The PSB inoculation significantly increased the shoot and root lengths, and fresh and dry weight of the millet seedlings. The study concluded that the PSB isolates from the millet rhizosphere in Lafia could enhance soil phosphorus availability and millet growth. The study recommended further research on the field application and optimization of the PSB inoculation.","PeriodicalId":511647,"journal":{"name":"Lafia Journal of Scientific and Industrial Research","volume":"3 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140443177","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, just a few studies have been conducted to assess the toxicity of the various sections of this plant. The goal of this study was to determine the toxicity profile of Musanga cercropioides methanol leaf extract in albino rats. Lorke's approach was used to conduct an acute toxicity study. In the first phase, nine (9) albino rats were randomly divided into three (3) groups of three (3) animals each. Each of the animals were orally administered 10,100 and 1000 mg/kg body weight of the extract. In the second phase, twelve (12) animals were used, which were divided into four groups of three (3) animals each. The first three groups received single doses of 1500, 3000, and 5000 mg/kg, respectively, while the fourth group which served as a control was given distilled water orally. After observation for 14 days, no signs of mortality were identified. The maximum dose supplied (5000 mg/kg body weight) did not affect the test animals' mortality or general behavior. When the treated groups were compared to the control groups, there was no significant difference (p > 0.05) in biochemical markers, body weight, or relative organ weights of liver, kidney, heart, and spleen. These findings show that oral administration of Musanga cercropioides methanol leaf extract is safe at a dose of up to 5000 mg/kg body weight in Wistar albino rats.\u0000 \u0000 \u0000 \u0000 ","PeriodicalId":511647,"journal":{"name":"Lafia Journal of Scientific and Industrial Research","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139959819","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}
