Isolation of Microorganisms Associated with Palm Oil Contaminated Soil
Aim: Palm oil processing generally generates lots of wastewater (palm oil mill effluent), this is usually discharged into
the environment in the untreated form and subsequently causes several environmental issues. There is therefore need to
isolate microorganisms that can be used to clean up the palm oil contaminated environment especially the soil.
Methods and Results: Palm oil contaminated soil was obtained from Oba Adeyemi palm oil mill in Oyo, Oyo State, Nigeria,
other soil samples which were purposely contaminated with palm oil, were obtained from Ajayi Crowther University
Oyo, Oyo State. Isolation, characterization and identification of microorganisms were carried out using morphological
and biochemical characterization. The isolates were preliminarily screened for lipolytic activities, this was confirmed
by growth on the mineral salt medium after 7 days, signifying hydrolysis. One of the prominent isolates was further
identified by sequences analysis of 16S rRNA genes. Forty-one bacterial isolates were identified, which included species of
Bacillus (80 %), Pseudomonas (20 %) in the oil mill contaminated soil sample and Bacillus spp. (100 %) in the purposely
contaminated soils. Twenty-nine fungal isolates including species of Aspergillus, Oidiodendron, Geotrichum, Penicillum,
Saccharomyces were isolated with Aspergillus fumigatus having the highest frequency of occurrence (37.5 %) in artificially
contaminated soil and Saccharomyces spp. having the highest frequency of occurrence (91 %) in palm oil contaminated
soil from the palm oil mill. Sequencing of the 16S rRNA of one of the prominent isolates showed that it was identified as
MN607220 Saccharomyces cerevisae. All the bacterial and fungal isolates had lipolytic activities except Bacillus mycoides
and Oidiodendron sp. respectively. Nine of the ten Saccharomyces sp. had lipolytic activities.
Conclusion: These screened organisms could therefore be employed for the cleanup of palm oil contamination in the
environment.
Significance and Impact of Study: Thereby ridding the environment of possible toxic effects especially in areas of need
like Malaysia
Scardovia Wiggsiae and the Other Microorganisms in Severe Early Childhood Caries
Severe early childhood caries (S-ECC) is an aggressive form of tooth caries in preschool children. New different bacteria were defined as associated with S-ECC. The aim of this study was to analysis the role of Scardovia wiggsiae and the other cariogenic microorganisms in S-ECC in Turkish children. Two same-sized groups of children were enrolled in the study: the first group consisted of 40 children with S-ECC (mean-age:52.93±11.5months), and the second group consisted of 40 caries-free children (mean-age:49.43±12.47months). The numbers of mutans streptococci, lactobacilli and yeasts were examined by culturing techniques, while the presences of S. wiggsiae, Streptococcus mutans, Streptococcus sobrinus, Actinomyces gerencseriae, Veillonella parvula, Fusobacterium nucleatum were examined by using 16S rRNA-based PCR technique in plaque samples. The prevalence of S. wiggsiae, S. mutans, A. gerencseriae, V. parvula and the numbers of mutans streptococci, lactobacilli, yeasts were found significantly high (P<0.05) in SECC. Also, the presence of S. wiggsiae with either S. mutans, A. gerencseriae, V. parvula or F. nucleatum were associated (P<0.01) with S-ECC. Understanding the effects of bacteria on initiation and progression of S-ECC will also help to improve protective and preventive treatments.
Preparation of Fibre Fortified Basundi Using Date Fruit (Phoenix dactylifera)
Fibre fortified basundi was prepared using different levels of dried crushed date fruit (Phoenix dactylifera) with a view to optimize the process for its manufacture and to study its chemical, sensory and microbiological qualities. Initially the preliminary trials were conducted by blending of different levels of date fruit crush viz; 0, 2, 4, 6, 8, 10 and 12% in the basundi with 5% sugar to finalize the experimental treatments.
Bacteriological Quality of Milk in Raw Bovine Bulk Milk in the Selected Milk Collection Centers: Smallholder Dairy Processing Ethiopia
Cross-sectional study was conducted to examine and identify quality of raw bovine milk from in Arsi Zone and East Shewa Zone, in Oromia, Ethiopia. The purpose of the study was to assess hygienic practices during milking, milk collection and bacteriological quality of cow’s milk in Arsi and East Shewa Zones milk collection centers.
Immunodeficiency and Microbial Infections
Immunodeficiency refers to failure of immune system to encounter infections by different microbial pathogens such as fungi, bacteria, viruses and protozoan. This is called acquired or secondary immunodeficiency syndrome (SIS).
Pharmacy Compounding Quality Control and Pharmaceutical Development Strategies for Seventeen alpha Hydroxyprogesterone Caproate in Prevention of Preterm Delivery
Seventeen alpha hydroxyprogesterone caproate (17-OHPC) is the only FDA-approved drug labeled for prevention of preterm delivery. This drug is also available as a compounded product from licensed compounding pharmacies. This article reviews the FDA approval history and pharmacy compounding quality control data of 17-OHPC, as well as briefly discusses possible future pharmaceutical development strategies for 17-OHPC.
Reduction of Bitterness and Enhancing Palatability of Cetirizine Oral Liquid Dosage Forms by Cyclodextrins
The aim of this manuscript is to study cyclodextrins (CDs) as a potential excipient to suppress bitterness and enhance palatability of pediatric liquid preparations for Cetirizine, an extremely bitter drug. Natural α, β and γ CDs; and β CD derivatives such as hydroxyl propyl (HP), randomly methylated (RM) and sulfobutyl ether (SBE) β-CDs were screened in different molar ratios of 1:1, 1:2 and 1:3 for their inhibition of the extremely bitter taste of Cetirizine using the human gustatory sensation test.
