PRODUCTION OF BIOPLASTIC (PHB) BY SOIL MICROBIAL ISOLATES: A REVIEW
AMINA USMAN UMAR AND UDEME JOSHUA JOSIAH IJAH.
Department of Microbiology, Federal University of Technology Minna, Niger State, Nigeria.
Polyhydroxybutyrate (PHB) is a very important polymer of polyhydroxyalkanoates. PHB accumulates inside numerous bacteria under nutrient-limiting conditions with excess carbon, and accumulates as distinct white granules during unbalanced growth in the cell. Soil microorganisms such as Pseudomonas, Bacillus, Alcaligenes, Halomonas etc, are capable of producing this intracellular lipid granule through the action of enzymes. These bioplastics are important in the food industries, agriculture, building and in medicine, due to their good aroma barrier, oxygen permeability, tensile strength and biomoldability. The main limitations for the bulk production of bioplastics are its high production and recovery costs. However, the use of agro waste, industrial by-products, genetic and metabolic engineering has allowed their biosynthesis in several indigenous and recombinant organisms by improving the yields of production and reducing overall costs. The future market for bioplastics will be increasing owing to its sustainability. Also, new innovations of bioplastics in the future can raise the efficiency of production and build new job opportunities most especially, in developing countries.

Contamination of water bodies due to anthropogenic activities of man has been a major concern to mankind particularly in developing nations where regulations by government are either not obeyed or no stringent regulations to monitor and punish the offenders. The biological wealth of a water body is mainly dependent on its physico-chemical parameters’ quality. The physico-chemical qualities of two waterbodies (Bayeiku and Offin Rivers) in Ikorodu division of Lagos State, were sampled and analysed with the intention of determining the extent of pollution and the health of the water bodies. Five sampling stations each were established on both rivers and samples collected monthly for six months (March to May 2021). The physico-chemical parameters were analysed using standard methods by APHA. The obtained result revealed that the average value of the parameters analyzed are; turbidity (29.71±23.03 NTU), conductivity (401.94±576.52 µS/cm), DO (33107.92±59091.09 mg/L), hardness (33107.92±59091.09) and that these values are above the WHO allowed limits except for temperature (29.09±1.65°C), pH (7.59±0.34) and salinity (3.05±3.45). One-way analysis of variance (ANOVA) and the 95% confidence level revealed that the value of each parameter was not statistically significantly (p ˃0.05). The variation of each parameter was as a result of pollution from activities that take place along the river bank.

Clinical iatrogenesis is seen as an “epidemic” that has bedeviled the modern medical institution that is being practiced in the hospital/clinics. This study was set to find out the implications of this epidemic on health delivery in Keffi. It aimed to find out the factors responsible for persistent occurrence of clinical iatrogenesis in Keffi town, its implications on health delivery and then proffer solutions that will curb its existence for an effective health delivery in Keffi and Nigeria at large. The data used for the study were collected through the administration of questionnaires, focus group discussions and observations made on the sampled population. Data were qualitatively analyzed in simple frequency and percentage table based on the one hundred and ten retrieved questionnaires. Misdiagnosis, illegible handwriting, wrong prescriptions, unnecessary/wrong surgical operations, improper keeping of patient’s records, impatience of practitioners, the monopolistic nature of practitioners over patients among other factors were discovered to be the causal factors to clinical iatrogenesis. This has negative implications on health delivery in Keffi. Thus, the government should encourage the training of more medical practitioners, in-house training/seminars/workshops to update practitioners’ knowledge on the use of modern tools, development of an effective policy that will ensure that negligent practitioners are appropriately discipline, disclosure of practitioners’ negligent acts among others. This will eradicate or reduce the occurrence of clinical iatrogenesis in Nigeria.

Salmonella as a group of microorganisms has long been recognized as an important zoonotic pathogen of worldwide economic significance in animals, birds and man. They are intestinal bacteria which give rise to enteritis and typhoid-like disease. The prevalence of Salmonella differs depending upon sample types, collection and handling methods, detection techniques and geographic regions and management systems. These differences may mask the impact of other factors such as raising practices, seasonal patterns and processing procedures that are actually causing true changes in the distribution of the bacteria. Salmonella infection causes not only decreased production performance and even death of poultry, but also contamination of the human food chain, leading to serious economic losses in the poultry business, as well as being a threat to public health. This review recommends that: The best preventive and control strategy is vaccination.

Federal Polytechnic Bali, Department of Biochemistry/ Chemistry
Caffeine is one of the most commonly use substance found in green seed coffee, green tea (Camellia sinensis) and other tea brand. Caffeine-containing products have been consumed for hundreds of years for their pleasant flavor and stimulating effects. The aim of this study is to determine the concentration of caffeine in some commonly consumed tea in Taraba state. Each tea sample was introduced into a 250ml beaker containing water and was boiled with the addition of Calcium trioxocarbonate to evaporate tannins. The solution was allowed to cool after filtration after which liquid to liquid extraction was done. Two layers of the solution was formed when tetra chloromethane was introduced into the solution. The caffeine moves into the tetrachloride phase since it is more soluble in carbon tetrachloride than water. Caffeine concentration present in SAM tea, Hilltop tea, Lipton tea, Top tea and Highland tea were calculated and showed values of 0.29, 0.17, 0.34, 1.05 and 0.34 in mg/ml. Top tea has the highest caffeine content, followed by Highland tea and Lipton tea. The least is hill top tea. The concentration of caffeine in top tea is the highest as a result, it would be the highest central nervous system stimulant among the other sample tested. This implies it could have a damaging effects among consumers, therefore, consumers’ consumption of the beverage is to be minimized. Caffeine sometimes can cause negative health effect in some individuals, therefore quantities of caffeine need to be shown on the label for the interest of those consuming them.

Information is vital at every stage of the product life. At the early-stage information about existing product is useful to enable setting of target during product definition. Furthermore, information about function, form and processing method are all important at the early stage. As the product becomes matured the information need is concern with its operation and disposal. For a successful product development process, there is need to study the product development process and the means of storing design information throughout the life span of the artifact. Ontology has proved to be one of the best tools for information storage indexing and retrieval. However, its use in product development process is not well emphasised. This paper scans through the existing ontology application to understand method applied to build them and the challenges and progresses register in them. It then proposed a need to deploy ontology for information capturing storage and retrieval at all stages of PDP. This can go a long way to assist new entrant into the industries to improve on their design capabilities.
