Streptomyces. nigra GH12, a new Actinomycete isolate identified by 16S rRNA used for dark green pigment production. Manipulations of the factors affecting pigment production are the most effective way to have maximum yield of pigment. Starch 2.5% (w/v), ammonium nitrate 0.2% (w/v), dibasic sodium phosphate 0.1% (w/v), inoculums size 6% (v/v), initial pH level of 8, 150 rpm rotation speed, 37 ºC temperature, and 9 days of incubation were found the optimum growth conditions for the highest green pigment production. The extraction of green pigment was performed efficiently with ethanol solvent. Results showed no effect on the pigment content at 40, 50 and 60°C. On heating pigment extract at 70, 80, 90 and 100oC for 60 min, retention of pigment remained as high as 97.4, 93, 86 and 79% of the total pigment density , respectively, even with continuous treatment at 100°C for more 60 min. The results indicated that the pigment extracts exhibited their greatest stabilities at high pH values, i.e. 8.0, 8.5, 9.0 and 10.0, during the entire holding time. The pigment was characterized by full UV-visible spectroscopic screening, where the potential absorption maximum of the target green pigment extract was recorded in the range of 300 ̶ 360 nm, with a λmax at 340 nm. Moreover, the chemical composition diversity of the pigment extract was further investigated by GC/MS analysis that revealed the presence of 57 metabolites in their silylated form.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":" 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242689","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}

Samples were randomly collected from both Area Councils and prepared for Analysis using Nitric acid digestion and Atomic Absorption Spectrometer (AAS). The mean concentration of Zinc (Zn) in AMAC were 0.88 ± 0.35mg/kg and 2.04 ± 0.57mg/kg in Kuje Area Council respectively. Results showed that the concentration of Zinc (Zn) in cow hide (Ponmo) from AMAC was two times as high as cow hide (Ponmo) from Kuje Area Council. The mean concentration of Zinc (Zn) in cow hide in both Area Councils were two times as high as the Food and Agricultural Organization Standard unit for Zinc(Zn), which is 0.03mg/kg -1.0mg/kg. However, potential accumulation may depend on the frequency of consumption or exposure. In contrast to many studies the samples had alot of nutritional value. Proximate analysis showed that the ponmo samples for Kuje had 54% proteinand 34.68% carbohydrate, moisture 5.3%, crude lipid 2.3%, ash 2.7%, fibre 0.82% while ponmo samples for AMAC had 51.4% protein, 36% carbohydrate, 5% moisture, crude lipid 4.3%, ash 2.1% and fibre 1.1% which suggests that Ponmo has some level of nutrient especially rich in protein and carbohydrate and low in fibre content. Cowhides from AMAC and Kuje Area Councils contain significant amount of zinc, which exceeded the standard limit and could pose a potential health risk to consumers depending on the frequency of consumption. Hence the need for monitoring of this metal concentration to avoid excessive bioaccumulation that could be harmful to health. This study also showed that cowhides is rich in some nutrients especially protein and carbohydrates and can be a substitute for meat protein.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"96 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135218509","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}

This is to assess the potential impact of climate change on wheat production under different irrigation treatments using the DSSAT-CERES wheat simulation model and climate change scenarios; to determine the best sowing date to be used as an adaptation strategy under climate change scenarios. The model effectively simulates wheat yield, with a high goodness of fit and d-Stat value, and low root mean square per observation, resulting in an overall goodness of fit of average 13.8 kg/fed. The model's performance was satisfactory, with high R2 and d-Stat values and low RMSE/obs, with overall values of 0.830, 0.951, and 2.3 mm, respectively for water consumption. The CERES-Wheat model accurately simulates wheat yield and water consumption, allowing us to assess climate change's impact on wheat yield in 2030 and 2040. The study shows a decrease in solar radiation (SR) by 1.9 and 2.1 MJ/m2/day in 2030 and 2040, while maximum temperature increases by 1.5 and 1.9°C due to climate change, and minimum temperature decreases by 1.8 and 2.3°C in 2030 and 2040. This results in an increase in potential evapotranspiration (PET) by 0.2 and 0.3 mm. The study predicts that season length will shorten in 2030 and 2040 due to temperature increases. In 2030, it will be reduced by 2, 4, and 4 days under different treatments. In 2040, it will be lower, with reductions of 3, 5, and 5 days. The study found that wheat yield losses would be lowest under the first sowing date and irrigation treatment, while the highest reductions were found under the third treatment. Climate change will reduce wheat water consumption due to shorter growing seasons and heat stress, with the lowest reductions occurring in 2030 and 2040 at 8 and 18%, respectively. The highest reductions in wheat yield were observed under the third sowing date and irrigation treatment. We suggest planting wheat in November, using full irrigation to prevent high-yield losses, and implementing adaptation strategies to reduce wheat plant vulnerability to climate change risks.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"505 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135617666","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}

It is an excellent source of energy but contains low amounts of protein and micronutrients. This study was conducted to assess the nutritional value and sensory properties of attiéké enriched with three legumes (cowpea, voandzou and common bean). The attiéké enriched with legume flours was prepared in different proportions of 10%, 15% and 20%. The samples were produced by incorporating the flour of the three legumes into the cassava paste in a single step (fermentation). The ferment content and fermentation time were 12% and 24 hours respectively. The chemical and sensory characteristics of the cowpea, voandzou and common bean enriched attiéké formulations were determined using standard methods. The results showed that the protein (1.13-9.93%), fat (0.06-2.06%), ash (0.1-1.13%), fibre (2-6.33%) and energy (353.747-372.06 Kcal/100 g) contents of the legume-enriched attiéké increased significantly with the cowpea, voandzou and common bean content. In addition, the addition of legume meal induced a significant increase in pH from 4.6 to 4.9. The incorporation of 10, 15 and 20% legume flours changed the appearance, aroma, taste, colour, and overall acceptability of the enriched attiéké compared to the control attiéké which were less appreciated by consumers. Flours with 10% legumes added to the cassava paste before the fermentation process yielded the most acceptable food compared to flours with 15 and 20% legumes added. This work suggests that the addition of 10% legume flour to the attiéké and proper fermentation improves both the nutritional value and sensory properties of the attiéké enriched with legumes.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135969274","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}

 Place and Duration of Study: Nana, Petit Bouaké, Subiakro and Zatta rice-growing lowlands in the Yamoussoukro district (Central Côte d’Ivoire) from May 2021 to April 2022.
 Methodology: Seed-eating birds were surveyed using the line transect method between 6.30 am and 6.30 pm. At each site, four surveys were carried out per month.
 Results: In total, 22 species of seed-eating birds belonging to six families and three orders were inventoried in the rice-growing lowlands of the Yamoussoukro district. Among them, Village weaver Ploceus cucullatus, Red-headed Quelea Quelea erythrops and Bronze Mannikin Spermestes cucullata were the predominant species. Five other species, Red-eyed Dove Streptopelia semitorquata, Magpie Mannikin Spermestes fringilloides, Northern Grey-headed Sparrow Passer griseus, Yellow-mantled Widowbird Euplectes macroura and Black-winged Bishop Euplectes hordeaceus were regular in these lowland rice fields. Numbers of these seed-eating birds were highest at the Subiakro site and at the spike development and maturation of the rice. In addition, their numbers were highest between March and October and lowest between November and February.
 Conclusion: This study indicates that eight seed-eating birds are likely to cause significant damage to rice crops, but their pressure could be reduced by planning harvests between November and February.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135830227","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}
