    <description>Title: Biochemical composition of the marine conditioning film: Implications for bacterial adhesion
&lt;br/&gt;
&lt;br/&gt;Authors: Jain, A.; Bhosle, N.B.
&lt;br/&gt;
&lt;br/&gt;Abstract: The conditioning film formed on glass panels was analysed for total carbohydrates (CFCHO), total proteins (CFP) and total uronic acids (CFURA). The influence of these compounds on the adhesion of three marine bacterial cultures, Pseudomonas sp. CE-2, Pseudomonas sp. CE-10 and Bacillus sp. SS-10 was also evaluated. One-way analysis of variance suggested a significant increase in the attachment of all three cultures to conditioned glass panels. Moreover, CE-2 (r = 0.874) and CE-10 (r=0.879) showed a significant positive correlation with CFCHO. Conversely, SS-10 (r = 70.69) showed a significant negative correlation with CFCHO. Backward multiple linear regression analysis indicated that CFCHO were the most predictive component of the conditioning film in explaining bacterial adhesion to the conditioned glass panels</description>

    <description>Title: Distribution of butyltins (TBT, DBT, MBT) in sediments of Gulf of Cadiz (Spain) and its bioaccumulation in the clam Ruditapes philippinarum
&lt;br/&gt;
&lt;br/&gt;Authors: Garg, A.; Anton-Martin, R.; Garcia-Luque, E.; Riba, I.; DelValls, T.A.
&lt;br/&gt;
&lt;br/&gt;Abstract: Surface sediment samples were analyzed for organotins namely tributyltin (TBT), dibutyltin and monobutyltin from six areas located in the Gulf of Cadiz (14 stations), Spain. The total butyltin ranged between undetected and 1,580 ng Sn g sup(-1). TBT generally prevailed in most of the samples, suggesting fresh inputs of butyltin compounds and/or less degradation of TBT. The observed levels of butyltins at several sites are much higher than that required to induce toxic effect on marine organisms, suggesting that these sediments are polluted with butyltin compounds. The clam Ruditapes philippinarum was used for studying bioaccumulation of butyltins by exposing them to contaminated sediments from the Gulf of Cadiz over a period of 28 days under laboratory conditions. Biota-sediment accumulation factor (BSAF) ranged from 0.44 to 3.99</description>

    <description>Title: Distribution of particulate carbohydrate species in the Bay of Bengal
&lt;br/&gt;
&lt;br/&gt;Authors: Khodse, V.B.; Bhosle, N.B.; Gopalakrishna, V.V.
&lt;br/&gt;
&lt;br/&gt;Abstract: Suspended particulate matter (SPM) of surface seawaters was collected during December 2003 to October 2004 at 10 stations in the Bay of Bengal, and analyzed for particulate organic carbon (POC), total particulate nitrogen (TPN), total particulate carbohydrate (TPCHO) and total particulate uronic acids (TPURA). The concentrations of POC, TPCHO and TPURA varied from 4.80 to 29.12, 0.85 to 4.24, 0.09 to 0.91 mu M C, respectively. The TPCHO-C and TPURA-C accounted for 6.6-32.5 % and 0.87-3.65 % of POC. The trends observed for the distribution of these compounds were generally similar to those recorded for the distribution of chlorophyll a (Chl a). The C/N ratios varied from 3.2 to 22.3 with most of the values being less than 10. This suggests that the organic matter was mostly derived from phytoplankton and bacteria. Relatively low C/N ratios and high TPCHO yield imply that freshly derived organic matter was present during SWM and FIM. Our data suggest that the quality and quantity of organic matter varied spatially and seasonally</description>
