AMYLOLYTIC POTENTIAL OF Arthrobacter sp. AND Bacillus aerius FROM WASTE DUMP-SITES OF TWO BAKERIES LOCATED WITHIN KADUNA METROPOLIS, NIGERIA
Authors: Obafunmi Tonidunni Ibukunola , Bakori Garba Faiza , Lawal Yunus Sumayya 
Published: July 2023

Bakery waste dumpsites are believed to harbour a variety of bacteria due to the presence of organic materials like flour, sugar, and other food residues. The conditions in these environments support the growth of bacteria with the ability to degrade starch into simple sugars because they produce amylases, an enzyme pivotal to the food and beverage production. As Amylases progressively gain relevance in several other starch-based processes, their availability becomes insufficient, and the need for amylases with unique and superior efficiency increases. The focus of this study was to isolate and characterize bacteria with amylase activity from the soil of bakery waste dumpsites to provide valuable insight into cheap sources of amylolytic bacteria and their potential biotechnological applications. The starch-agar medium was used to isolate and screen amylase-producing bacteria by streak plate method. Two isolates, A2 and A4, showing the most hydrolytic activities of 21 + 0.1 mm and 25 + 0.1 mm, respectively, were identified by their cultural and cellular morphologies, biochemical characteristics, 16S rRNA gene sequence, and nearest phylogenetic neighbour as Arthrobacter sp. and Bacillus aerius. Based on their culture and amylolytic temperatures, Arthrobacter sp. (37 0C) and Bacillus aerius (45 0C) tend to produce amylases that can be explored in low to moderate and moderate to torrid industrial processes, respectively.

Published: July 2023

A week old 150 Arbor Acre strain of broilers fed UMUCASS 36 cassava root meal were used to evaluate the carcass characteristics, organ proportion, blood and serum chemistry and digestibility of the birds. The cassava was harvested, washed, peeled, chipped, oven dried and milled. The processed cassava root meal was used to formulate five diets, at 0, 25, 50, 75 and 100% levels designated D1, D2, D3, D4 and D5 respectively to replace maize. The birds were assigned in a Completely Randomized Design to five treatments with three replicates of ten birds per replicate. The carcass characteristics of broilers fed diet D2 was more superior and significantly (P>0.05) different from other broilers on the other diets. The superiority reflected in the bled weight, plucked weight, dressed weight and dressing percentage with the following values: 2136.67g, 2056.67g, 1723.33g and 77.71% respectively. The same trend was seen the values of the cut parts. Broilers on diet D5 had the highest percentage weight in heart (0.81%), liver (3.81%), gizzard (3.31%) and kidney (1.29%) while broilers on diet D2 had the least percentage of heart weight (0.38%), liver (1.33%), gizzard (1.11%) and kidney (0.57%). The experimental diets had no deleterious effects on the haematology and the blood serum of the broilers. Broilers placed on diet D2 had the best digestibility coefficients in all the digestibility parameters when compared with broiler chickens fed other diets. From the ongoing, it can be concluded that broilers on diet D2 performed best therefore, diet D2 is recommended.

The research affirmed that Cola nitida L. and Garcinia kola Heckel used in Nigeria are quite different medicinally and nutritionally. The proportions of all nutrients analyzed quantitatively (lipid, moisture, fibre, ash, and protein except carbohydrate) were greater in C. nitida than in G. kola Heckel (p<0.05). C. nitida has a lower energy density than G. kola Heckel (332.20 kcal/g vs 349.10 kcal/g sample) (p<0.05). Alkaloids, flavonoids, phenolics, and cardiac glycosides were all significantly greater in G. kola Heckel than C. nitida at p<0.05, in addition to saponin, tannin, and steroids. A 72-hour methanol extraction of kola nuts by cold maceration showed that C. nitida had significantly lower total phenolic, flavonoid, and tannin contents than G. kola Heckel (TPCs: 1815.38±125.90 µg GAE; TFCs: 385.80±37.24 µg QE; and TTCs: 2643.75±36.08 µg TAE/g sample). 2.2-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays showed that G. kola Heckel (IC50 = 133.70 ± 0.11 µg/mL) was more effective than C. nitida (IC50 = 226.70 ± 0.21 µg/mL) at the 0.05 level. Studies on anti-inflammation found similar effects for G. kola Heckel and C. nitida (antiproteinase activity IC50 = 162.90 and 223.60 µg/mL; albumin denaturation: IC50 = 155.10 and 347.20 µg/mL; and membrane stabilization: IC50 = 183.50 and 271.70 µg/mL). Thus, it is proposed here that G. kola Heckel, in comparison to C. nitida, may be an acceptable source of energy, an antioxidant, and an anti-inflammatory agent in the nutraceutical and pharmaceutical sectors for the benefit of humans.

Published: July 2023

Mental illnesses have been known to distress the general population as a whole. Notably, no social demographic is exempt from mental illnesses with the modern dynamics and challenges increasing the magnitude of mental illness. Students especially in higher learning institutions are not spared from the over-increasing mental illnesses. Despite the challenges brought about by mental illnesses among the students, stigmatization of the mentally ill has been high among them. This has seen increased drop-out of school, total insanity and sometimes suicide due to lack of psychosocial support among the mentally ill students, especially their peers. The mass media has been a critical tool of communication. However, there is little evidence on its role in mental health stigmatization hence this study seeks to assess the role of mass media channels on the mental illness stigmatization among college students. The research utilized the descriptive survey design and where both qualitative and quantitative methods were used to collect and analyze the data. The target population of this study comprised of the students at the Kenya Medical Training College (KMTC). There were 51045 students in the college as of July 2022. A questionnaire was used to collect data from the students. The data was analysed using mixed method analysis where both quantitative and qualitative data was analysed. The quantitative data was analysed using inferential and descriptive statistics through SPSS. Content analysis was used to analyse the qualitative data. The findings revealed that mass media channels played a critical role in determining the spread of information and the perceptions of mental illness among students. The channels of mass media communication were found to instigate mental illness stigmatization among college students. Digital media was found to have the strongest influence on mental health stigmatization followed by broadcasting media, print media and outdoor media. It is recommended that these channels of mass media ought to be more positive and encourage students to uphold and accept the mentally ill to minimize stigmatization.

Abstract: Grass is one of the plants that live on God's earth, even grass is also written in Al-quran. Grass is currently also a pest for plants, so sometimes to minimize grass growth, many farmers or people eradicate grass by cutting it even by poisoning the grass. Each method used has its own risk of work accidents, such as using grass poison can experience insecticide poisoning. To anticipate this, a remotecontrol robot that sprays automatic grass poison using the PID method is designed. The test results found that the robot works with a voltage of 11.1 VDC with a 5-12VDC motor with a speed of 3000rpm and a gearbox motor is used so that it turns into a 5Kg load torque. Meanwhile, for control using the HC-05 interface which is connected to Android, the maximum distance transmission system is 0-10m. For watering grass, it has 2 scala heights, grass with a height of 10-15 uses PID 1, which is watered with a voltage of 11.1VDC delay (t) 1.5s. Grass with a height of 25-30 using PID 2, watered with a voltage of 14.8VDC delay (t) 3s. All watering the grass uses a 16VDC pump motor with 1500 rpm. After the robotic watering system is applied using the PID method, the P value = 14.56. The value of I = 22.08 and the value of D = 15.5.

Published: July 2023

Abstract: Traffic accidents are one of the biggest contributors to injuries and fatalities worldwide. Victims of traffic accidents range from minor injuries to severe injuries and even death. The severity of many accidents is often due to a lack of discipline and public awareness of traffic rules and safety measures. Car manufacturers have attempted to mitigate the effects of accidents by providing seat belts. However, many people neglect to use them, thinking that nothing will happen while driving. Even with fines imposed by authorities, people can outsmart them by removing their seat belts when officers are not around. To address this issue, a model has been developed to monitor drivers using artificial intelligence and computer vision. The camera captures images, which are then processed by a neural network trained with the YOLOv5 algorithm. The model has an average precision of 89% and a recall of 81%, and can accurately detect whether drivers are wearing seat belts or not. This model is expected to aid in improving driver and passenger safety on the roads. By paying attention to the use of seat belts, the severity of injuries sustained in accidents can be reduced. Keywords: computer vision; neural network; seatbelt detection; yolo Abstrak: Kecelakaan lalu lintas merupakan salah satu penyumbang terbesar cedera dan kematian di seluruh dunia. Korban kecelakaan lalu lintas tidak hanya mengalami cedera ringan, tetapi juga cedera berat bahkan kematian. Parahnya banyak kecelakaan yang terjadi dapat disebabkan oleh kurangnya disiplin dan kesadaran masyarakat akan aturan lalu lintas serta tindakan keselamatan. Produsen mobil telah berusaha untuk mengurangi efek kecelakaan dengan menyediakan sabuk pengaman. Sayangnya, masih banyak orang yang mengabaikan penggunaannya, dengan menganggap bahwa tidak akan terjadi apa-apa saat mengemudi. Meskipun ada denda yang diberlakukan oleh pihak berwenang, orang masih dapat melepaskan sabuk pengaman ketika tidak ada petugas di sekitar. Untuk mengatasi masalah ini, sebuah model telah dikembangkan untuk memantau pengemudi menggunakan kecerdasan buatan dan visi komputer. Kamera mengambil gambar yang kemudian diproses oleh jaringan saraf yang dilatih dengan algoritma YOLOv5. Model ini memiliki presisi rata-rata sebesar 89% dan recall sebesar 81%, dan dapat dengan akurat mendeteksi apakah pengemudi menggunakan sabuk pengaman atau tidak. Model ini diharapkan dapat membantu dalam menangani masalah keselamatan pengemudi dan penumpang di jalan raya.
