Phytoplankton diversity and abundance in Ndop wetland plain, Cameroon

  Phytoplankton is very sensitive to nutrient changes. Very little work has been carried out on the effect of these changes on the phytoplankton community in the Ndop wetland. Four paddy-field sites were studied to evaluate the effect of some abiotic factors on their occurrence and abundance of phytoplankton. Water samples were collected from the paddy-fields sites following age gradient 34, 32, 22...

Ecofriendly application of cellulase and xylanase producing marine Streptomyces clavuligerus as enhancer in biogas production from waste

  The marine actinomycete strain MAC 9 was used for the production of cellulase and xylanase from wheat bran with inducers oats and soy meal as substrate. Out of 30 actinomycetes screened from sediments of Tiruchendhur coastal areas of Tamil Nadu, India only 8 strains showed both cellulase and xylanase activity. The marine actinomycete exhibited highest enzyme activity at alkaline pH 8-9 with temperature...

Isolation of biosurfactant-producing marine bacteria

  Biosurfactant-producing marine bacteria were isolated from oil-spilled seawater collected from harbors and docks in Mumbai, India. Haemolytic activity, emulsification activity toward n-hexadecane, emulsion of mixtures of oils, drop collapsing test as well as oil displacement test were used to determine biosurfactant producing activity of marine bacteria. Among 25 strains, 20 different strains showed...
