The experiment was conducted to measure the feasibility of partial replacement of skim milk with different levels of coconut milk in the manufacture of dahi. Skimmed milk was replaced by 0, 5, 10, 15 and 20% of coconut milk to produce Dahi designated as A, B, C, D and E. All the samples were analyzed for organoleptic, chemical and microbiological qualities. Replacement of skim milk up to 10% with coconut milk increased total organoleptic score but score decreased when level of coconut milk was 15% and 20%. Dahi manufactured by incorporating 5% coconut milk gave superior results for body and consistency and also for colour and texture. In all levels of replacement increased fat, carbohydrates, ash and total solids were obtained, while protein and pH content were significantly decreased in Dahi samples. Total bacterial count was higher in the dahi manufactured by replacement of coconut milk than control. It could be concluded that 5 and 10% replacement of skim milk with coconut milk for the manufacturing of Dahi was acceptable and reduced the production cost and they were better in compare to others, according to organoleptic, chemical and microbiological analysis. The work showed the potential of coconut as an alternative source of skim milk in dahi manufacturing with improved nutritional value and consumer acceptability.Asian J. Med. Biol. Res.

An experiment was conducted to measure the feasibility of incorporating carrot (Dascusa carota) juice in the manufacture of dahi. Four different types of dahi were manufactured by adding 0, 5, 10, and 15 per cent carrot juice to skim milk. The prepared dahi samples were subjected to physical, chemical and microbiological analysis to evaluate their qualities. Data on physical, chemical and microbiological parameters were recorded and analyzed. It was observed that the addition of carrot juice with skim milk improved the physical qualities. Dahi with 5% carrot juice was superior to other dahi samples in respect of smell and taste, body and consistency and also for colour and texture. Chemical analysis showed that addition of carrot juice increased the total solids and acidity content but decreased the protein, fat, ash and pH content. Total bacterial count was higher in the dahi samples manufactured by incorporating carrot juice than the control. From this study, it was suggested that dahi could be successfully manufactured from skim milk by incorporating carrot juice and 5% was found better for this purpose.Bang. J. Anim.

Due to the ubiquitous nature of bacteria and fungi, the microbiological analysis of environmental surfaces (chairs, tables, floors, hand rails, toilet door knobs and class door knobs) of five (5) secondary schools in Birnin Kebbi metropolis was carried out. Surface swabbing method was used for the collection of a representative sample on the surfaces. Media such as Nutrient agar, Eosin methylene blue, Sabouraud dextrose agar, and Mannitol salt agar were used for the isolation of the organisms. The total bacterial count ranged from 1.1×102 to 9.9×103 CFU/ml, while the total fungi count ranged from 0.0 to 3.6 ×103 CFU/ml. The bacteria isolated include: Corynebacterium kutsceri, Lactobacillus casei, Bacillus sphaerious, Staphlococcus aureus, Bacillus subtilis, Aeromonas spp, staphylococcus epidermidis, Pseudomonas spp, Micococcus varians, while the fungi isolated include Rhizopus stolonifer, Saccharyomyces cerevisae, Alternaria alternate, Aspergillus niger, Mucor spp., Fusarium spp. The isolation of these organisms followed series of procedures, starting with samples collected with swab sticks emulsified with peptone water, followed by the sterile dilution of each sample to a factor of 10-1 for chairs, tables, hand rail and door knobs while floor was diluted to a factor of 10-2. One millilitre (1ml) aliquots of which was used as a representative sample used for isolation of pure colonies was followed by series of biochemical test to confirm the identification of each isolate. Despite the routine cleaning practiced in secondary school setting, isolation of microorganisms from secondary school setting is inevitable.

Biological implant failures are primarily related to biofilm, which can lead to peri-mucositis and, further on, peri-implantitis. The 810-nm diode laser has an affinity for pigmented chromophores, so its use in the peri-implant sulcus has a significant bactericidal effect on the black-pigmented anaerobes such as Porphyromonas gingivalis. Therefore, it can be used to eliminate or reduce the bacterial count in the peri-implant sulcular fluid (PISF), thus increasing the life of the implants and reducing the chances of failure. The purpose of this study was to evaluate the efficacy of the 810-nm diode laser for the maintenance of dental implants and its use as a regular in-office tool for limiting the microbiological count in the PISF. Twenty patients undergoing implant treatment at the Department of Periodontology and Oral Implantology were randomly selected for the study. PISF samples were collected before and after the sulcus was lased with an 810-nm diode laser and sent for quantitative microbiological analysis using universal bacterial count, and the quantity of P gingivalis was evaluated using real-time polymerase chain reaction (PCR). The analysis revealed that after diode application, the median percentage drop in the microbial count was 76.67% and the median percentage drop in P gingivalis count was 99.28%. The use of an 810-nm diode laser resulted in the following outcomes: (1) drastic reduction in the total bacterial count around the implant and (2) significant reduction in the P gingivalis count, as evaluated by real-time PCR.

This study aimed to calculate the total bacteria and to identify the proteolytic bacteria in rumen and reticulum of local Kacang goat. The samples used were the rumen and reticulum fluids of five goats at abattoirs in Banda Aceh. Isolation of proteolytic bacteria was carried out using skim milk agar with pour plate method and incubated at 39° C for 48 hours. The bacterial colonies morphology was observed and the total bacterial count was recorded. DNA of the widest proteolytic index colony was isolated, amplified, and sequenced. The results showed that the dominant colonies morphology was white with position inside the agar. The average of total proteolytic bacteria in goat rumen fluid and reticulum fluid were 6.416x106 CFU/mL and 2,382x107 CFU/mL, respectively. Isolates with the widest proteolytic index was Ru3 (2.5 mm) in the rumen which homology and phylogenetic tree analysis of 16S rRNA showed 93% sequence similarity with Bacillus subtilis, while in reticulum was Re1 (2.0 mm) which has 92% sequence similarity to Tatumella. It is concluded that the number of proteolytic bacteria in reticulum is greater than the number of proteolytic bacteria in the rumen of local kacang goat. Homology analysis in this study proved that the Ru3 and Re1 isolate were probably either a new species or unconfirmed species.

The experiment was conducted to determine the optimum level of egg in the manufacture of buffalo milk pudding. Three types of pudding were prepared using different levels of eggs (40%, 30% and 20% by weight) and a constant level of corn flour (4%) at Dairy Technology and Microbiology Laboratory of the Department of Dairy Science, Bangladesh Agricultural University, Mymensingh. Quality of pudding was evaluated by physical, chemical and microbial test. From the result of physical study (smell and taste, body and consistency, color and appearance) it was found that pudding of 40% egg obtained the best score (97.50±3.77) followed by 30% (83.96±2.52) and 20% egg containing pudding (74.93±1.01). The differences within the overall score with different level of egg had significant effect. Chemical analysis showed the significant differences (p<0.01) within the total solids (TS) (340.61±1.72, 334.18±2.10 and 327.48±2.61), moisture (659.39±1.72, 665.82±2.10 and 672.52±2.61), fat (79.37±1.90, 76.43±2.76 and 73.47±3.62), protein (60.43±0.90, 53.82±0.57 and 47.07±0.25), carbohydrate (194.02±1.07, 197.33±1.17 and 200.57±1.21) and pH (6.90±0.00, 6.93±0.21 and 6.87±0.22) but no significant differences was found in ash (6.78±0.14, 6.58±0.13 and 6.38±0.01) and acidity percentage (0.071±0.00, 0.071±0.00 and 0.071±0.00%). Microbial analysis showed that there were significant differences (p<0.01) in total bacterial count (43.00±2.65×104, 38.33±1.53×104 and 35.00±3.00×104) in the pudding containing different levels of eggs. The experiment concluded that the egg level has a significant effect on the buffalo milk. The better result for buffalo pudding is at 40% egg level by weight with 4% constant corn flour.

Studies have shown that ozone is a good oxidizer and a strong disinfectant. There are many uses for ozone in the food industry, but there is relatively little information about the influence of ozone on biochemical composition and the capacity to reduce the number of microorganisms in birch sap. In this study, sap was ozonated at different intervals for 5 min (O3: 0.087 ± 0.009 mg L−1), 10 min, 15 min, 20 min, 25 min, or 30 min (O3: 0.99 ± 0.09 mg L−1). The parameters of the birch sap were studied immediately after the ozone treatment as well as during storage for seven days at 2 °C and for five days at 20 °C. The parameters of ozonated birch sap were compared with the parameters of fresh sap (control). The microbiological analysis included total bacterial count, lactic acid bacterial count, and yeast and mold count. Birch sap color, pH, titratable acidity, and ºBrix values were also determined. Evaluation of monosaccharides, sucrose, total sugars, and ascorbic acid was carried out in fresh sap as well as sap ozonated for 30 min, immediately after ozonation. The results show the statistical significance of the inactivation of microorganisms after treatment in most cases. The microorganism counts gradually reduced with increasing intervals of ozone treatment. The best results were obtained after 25 and 30 min of ozonation. Ozone treatment did not significantly influence the pH, titratable acidity, or °Brix statistically. Values of monosaccharides, sucrose, total sugars, and ascorbic acid were influenced within the margin of error. Ozone had a significant influence on the chroma and hue angle.
