Production and characterization of microbial levan using sugarcane (Saccharum spp.) juice and chicken feather peptone as a low-cost alternate medium

Optimization of rhamnolipid production by Pseudomonas aeruginosa OG1 using waste frying oil and chicken feather peptone

In the present study, production of rhamnolipid biosurfactant by Pseudomonas aeruginosa OG1 was statistically optimized by response surface methodology. Box-Behnken design was applied to determine the optimal concentrations of 52, 9.2, and 4.5 g/L for carbon source (waste frying oil), nitrogen source (chicken feather peptone), and KH2PO4, respectively, in production medium. Under the optimized ...

Direct Somatic Embryogenesis for Rapid , Cost Effective Production of Transgenic Sugarcane ( Saccharum Spp . Hybrids )

During the last decade, considerable effort has been expended in developing an efficient transformation system for sugarcane. Most protocols employ microprojectile bombardment of gene constructs into embryogenic sugarcane callus. The numbers of transgenic plants produced per bombardment range from 0.1-20 globally, with genotype response and selection regime appearing to be the most important fa...

The Biology of the Saccharum spp. (Sugarcane)

Enhancement of Pseudomonas Aeruginosa Growth and Rhamnolipid Production Using Iron-Silica Nanoparticles in Low-Cost Medium

The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...

Characterization of sugarcane (Saccharum spp.) leaf senescence: implications for biofuel production

BACKGROUND Second-generation ethanol (2G-bioethanol) uses lignocellulosic feedstocks for ethanol production. Sugarcane is one among the most suitable crops for biofuel production. Its juice is extracted for sugar production, while sugarcane bagasse, straw, and senescing leaves are considered industrial waste. Senescence is the age-dependent deterioration of plant cells, ultimately leading to ce...
