Forty samples of freshwater clam (Batissa violacea), popularly known as Kai, collected from the Suva market were analysed for total aerobic plate count and total coliforms. The heterotrophic bacteria isolated by plate count were also characterised up to genera. The results indicated higher than acceptable level of plate count and coliform bacteria. While total plate count of aerobic heterotrophic bacteria ranged from 5.5 x 105 colony forming units (cfu) per gram to more than 107 cfu/ gram, total coliform load varied between 1.1 x 104 to 1.1 x 105 per 100 gm of Kai flesh.

Nitrogen fixation is carried out only by prokaryotes, mainly some cyanobacteria and heterotrophic bacteria.

Abstract ABSTRACT A standardized system has been established wherein microbes were recovered from specific sites (waters, sediments, slimes, tubercles) and at least six physiologically different groups of microbes were characterized and identified. These organisms were selected for properties known to be associated with microbial influenced corrosion (MIC), such as slime formation, acid production, sulfate reduction, iron chelation and precipitation, and hydrogen utilization. The organisms were characterized by their fatty acid composition. Coupons of the test material were embedded in epoxy,

Abstract:
The effect of eucalyptus honey addition on the safety and extend the shelf life of local cream was evaluated. Cream was manufactured by the corporation various concentrations of bee honey (0, 5, 10,15 and 20) % and kept under cool temperature (6 + 1) °C for 15 days. Several variables were determined to assess the bee’s honey influence samples with time of the storage on cream quality which those involved the total viable count, coliform, psychrotrophic bacteria, yeasts and molds as well as peroxide value, acid degree value (ADV), these tests were carried out at the age of 0, 5, 10 and 15 days.

Abstract:
Fermented products have gained worldwide popularity for their nutritional and health aspects. Many studies have been done on this topic, including fermented cabbage (sauerkraut). Yet little or no studies are done on evaluation of fermented cabbage juice which is considered as by-product of sauerkraut production, still rich in bioactive compounds. In order to reduce food waste, sustainable solutions are being searched for to preserve valuable fermented cabbage juice. The aim of this study was to evaluate chemical and physical composition of concentrated fermented cabbage juice and their changes

Abstract:
Burn injuries of the skin are one of the most common household injuries which vary depending on the way of induction and its severity. Common complications are sepsis of the wound and immunosuppression. A total of 44 burned patients were included in the study. Blood samples and a swab were taken from the location of burn from each patient. All cytokines (IL-5, IL-6, IL-10, G-CSF, TNF and IFN) were evaluated using the ELISA technique. Swabs were cultured and the bacterial growths were tested for sensitivity to 20 different antibiotic discs. Hematological tests were performed and compared to the

Abstract:
This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a
