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

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.

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.

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.
