O objetivo do presente trabalho é avaliar as características físico-químicas e microbiológicas dos reservatórios da região do semiárido brasileiro, receptores de água do Projeto de Integração do rio São Francisco, identificando a influência de variáveis ambientais na comunidade fitoplanctônica. Foram estudados os reservatórios de Itaparica, Poço da Cruz, Boqueirão, Armando Ribeiro Gonçalves e Castanhão. Para alcançar o objetivo proposto, foram feitas análises estatísticas multivariadas com auxílio dos programas Primer e SPSS. Verificou-se que os reservatórios se diferenciam em dois grupos (Eixo Leste e Eixo Norte), observando-se a existência de uma variação temporal. As variáveis ambientais explicaram 78% da variação do fitoplâncton. Destes 22% são explicados por variáveis tipológicas (naturais) e 56% são explicados por variáveis de pressão (efeito antropogênico). Espera-se que a transferência de água possa contribuir para melhoria da qualidade da água, sendo fundamental a implementação de medidas que promovam uma gestão integrada e sustentável das respectivas bacias hidrográficas. Palavras-chave: variáveis ambientais, fitoplâncton, reservatórios, semiárido The Influence of Environmental Variables on Phytoplankton Community of the Receptors Reservoirs by the São Francisco River Integration Project ABSTRACT This study aims to evaluate the physico-chemical and microbiological characteristics of brazilian northeast reservoirs, from the São Francisco river Integration Project, to identify the influence of environmental variables on the phytoplankton community. There were studied the reservoirs of Itaparica, Poço da Cruz, Boqueirão, Armando Ribeiro Gonçalves and Castanhão. To achieve the proposed aim, multivariate statistical analyses were performed with the Primer and SPSS programs. It was observed that the reservoirs are distinguish in two groups (East and North Axis), observing the existence of a temporal variation. It was verified that the environmental variables explained 78% of the phytoplankton variation. Of these, 22% are explained by typological variables and 56% are explained by pressure variable. It is expected that the transfer of water may improve water quality (especially in reservoirs of the East Axis). It is essential to implement actions to promote an integrated and sustainable management of their watersheds. Keywords: environmental variables, phytoplankton, reservoirs, semiarid

The current investigation was undertaken with the aim of studying the effect of breed of the animal on various physico-chemical, compositional and microbiological characteristics of bovine colostrum. While studying the effect of breed of the animal on various physico-chemical, compositional and microbiological characteristics of colostrum, it was found that the specific gravity, fat, total protein, casein protein, whey proteins, Lactose, total solids and solids not fat of the colostrum samples from local non-descript animals were significantly (p £ 0.05) lower compared to all other animal sources (breeds) under study. The fat content of Jersey cross (fi) [Jersey cross under field conditions] was significantly (p £ 0.05) higher than Jersey cross (fa) [Jersey cross under farm conditions]. Total protein content of Jersey and Jersey cross (fi) were found to be comparable however both these samples were found to be possessing significantly (p £ 0.05) higher values than Jersey cross (fa). Casein protein of Jersey and Jersey cross (fi) was found to be comparable however both these samples were found to be possessing significantly (p £ 0.05) higher values than Jersey cross (fa). Lactose content of Jersey was significantly (p £ 0.05) higher than Jersey cross (fi). Total solids content of Jersey cross (fi) was significantly (p £ 0.05) higher than Jersey cross (fa). Jersey cross (fi) possessed significantly (p £ 0.05) higher solids not fat content than Jersey cross (fa) and the values were found to be comparable with Jersey colostrum samples. The pH values of colostrum samples of Jersey were seen to be significantly (p £ 0.05) higher than all other sources of colostrum viz Local, Jersey cross (fa) and Jersey cross (fi). Amongst the latter three, the values were found to be comparable. The ash, electrical conductivity and total plate count (TPC) of the colostrum samples of the animal sources under study were found to be possessing comparable values having no significant (p greator than 0.05) difference among themselves whatsoever.

Monthly Variations

The present study was carried out to determine the monthly variations of physico-chemical parameters in water samples from Chiffa river at Blida, North West of Algeria from April to August 2006. Water samples were analyzed for physico-chemical parameters and the results showed their monthly variations as follows: pH 7.5-7.6, electrical conductivity 0.87–1.06 mS·cm−1, nitrate 0–7.00 mg·L−1, nitrite 0–0.28 mg·L−1, ammonia 0–0.03 mg·L−1, phosphate 0–0.94 mg·L−1, sodium 19.3–47.0 mg·L−1, chloride 35.7–52.0 mg·L−1, calcium 90.3–104.7 mg·L−1, magnesium 27.3–37.7 mg·L−1, organic matter 0.4–3.9 mg·L−1, chlorophyll a 0.7–132.3 mg·L−1, and bicarbonate 219.3–248.7 mg·L−1. The analyzed physico-chemical parameters were almost not exceeded the maximum permissible limit of WHO and Algerian Water Quality Guidelines. A total of 53 taxa belonging to 4 divisions have been identified, including Chlorophyta (52.83% of taxa), Bacillariophyta (28.30%), Cyanophyceae (16.98%), and Charophyta (1.89%).

Loloh is a Balinese traditional beverage made from one or a combination of several herbal extracts. The most popular variants of loloh in Bali are loloh tibah and loloh cem-cem, which are continuously produced every day. During distribution, loloh is stored at room temperature. The study was aimed to study the physico-chemical and microbiological characteristics of loloh cem-cem and loloh tibah during storage at room temperature.  This study used a purposive random sampling. The samples consisted of 14 loloh sellers in Badung-Denpasar. Type parameters that were observed during a 24 hour-storage at room temperature included pH, total soluble solid, titratable acidity, ascorbic acid, total plate count, total yeast and mold count. During room temperature storage, the level of total plate count, total mold/yeast of loloh cem-cem and loloh tibah changed significantly. The shelf life of loloh cem-cem was only 12 hours at room temperature (28-30 oC) with the characteristics of pH 2.95, TSS 5.67 °Brix, vitamin C 19.35 mg/100 g, titratable acidity 0.24%, log total plate count 6.48 Cfu/mL, log total mold/yeast 5.01 Cfu/mL. The shelf life of Loloh tibah was only 12 hours at room temperature (28-30 ºC) with the characteristics of pH 3.34, TSS 4.21 °Brix, Vitamin C 10.20 mg/100 g, titratable acidity 0.13%, log total plate count 6.68 Cfu/mL, log total mold/yeast 5.86 Cfu/mL. Beyond the 12 hour-storage, both of the lolohs had higher total colony counts than the upper standard limit.
