The present study was designed to test the immunostimulatory efficacy of poly-β hydroxybutyrate-hydroxyvalerate (PHB-HV) extracted from Bacillus thuringiensis B.t.A102 on the immune system of Oreochromis mossambicus. Fish were fed with 0%, 1%, 3% or 5% PHB-HV supplemented feed and were bled at regular intervals of 5 days. The specific immune response was(More)
Polyhydroxyalkanoates (PHAs) are natural polyesters produced by microbes, a potential alternative to synthetic plastics. Various methods ranging from gravimetry to spectrophotometry are routinely used for qualitative analysis of extracted PHA. There is a great need for accurate quantification of intracellular PHA during bioprocess. Hence, the present study(More)
An indigenous Bacillus thuringiensis strain B.t.LDC-391 producing cytocidal proteins against human colon cancer cell line, HCT-116, was subjected to phenotypic and genotypic characterization to evaluate its relatedness to B.anthracis. The morphological features of this strain were meta-analyzed with data of other parasporin and insecticidal protein(More)
Observing the environment and recoganizing patterns for the purpose of decision making are fundamental to any scientific enquiry. Pattern recognition is a scientific discipline so much so that it enables perception in machines and also it has applications in diverse technology areas. Among the scientific community, statistical pattern recognition has(More)
Polyhydroxyalkanoate (PHA) is a promising polymer for various biomedical applications. There is a high need to improve the production rate to achieve end use. When a cost-effective production was carried out with cheaper agricultural residues like molasses, traces of toxins were incorporated into the polymer, which makes it unfit for biomedical(More)
The immunostimulatory effect of phospholipopeptide biosurfactant from Staphylococcus hominis (GenBank Accession No: KJ564272) was assessed with Oreochromis mossambicus. The non-specific (serum lysozyme activity, serum antiprotease activity, serum peroxidase activity and serum bactericidal activity), specific (bacterial agglutination assay) immune responses(More)
Digital images are powerful and widely used communication medium in many fields like medical imaging, digital forensics, surveillance, journalism, etc. The availability of sophisticated digital image technology has given rise to image forgery. The forgeries are very difficult for a human eye to detect. Passive tampering detection method aims to detect the(More)
