Polyethylene and polypropylene are the two polyolefins with wide ranging applications. They are recalcitrant and hence remain inert to degradation and deterioration leading to their accumulation in the environment, and, therefore creating serious environmental problems. In this review, biodegradation of these two polymers under in vitro conditions is reported. An attempt has been made to cover the mechanism of biodegradation, the various bacterial and fungal organisms that have been reported for the same, methods adopted for the studies and different characterization techniques followed to measure the extent of degradation

Keywords: polyethylene, polypropylene, biodegradation, in vitro

Forensics for tracing microbial signatures: Biodefence perspective and preparedness for the unforeseen

Biological weapons are assigned high priority in homeland security, defence, counterproliferation, nonproliferation, intelligence, and counterterrorist programmes. In order to strengthen active defense against development and use of these weapons, several comprehensive technological and forensic capabilities have been developed world over for investigative, intelligence, prosecutive, diplomatic and policy purposes. Microbial forensics is one of such strategies. It is a new discipline combining microbiology and forensic science. Microbial forensics associate the source of the causative agent with a specific individual or group by measuring molecular variations between related microbial strains. In this context, several advanced molecular techniques and practices including molecular phylogeny, whole genome sequencing, microarray analysis, DNA finger printing, etc., can be extremely valuable and effective analytical tools in a microbial forensic investigation. Results from such analyses may be related to the intentional use of microbial agents for bioterrorism or the accidental release of any offensive microorganisms or toxins of public health significance, specifically for the purpose of determining the origin. The new discipline of microbial forensics is an integration of an array of well established fields, such as microbial genomics, phylogenetics, forensic informatics and classical microbiology.

Nutrigenomics: Looking to DNA for nutrition advice

With the success of ‘Human Genome Project’ and the powerful tools of molecular biology, we have entered the era of genetic nutrition. The publication of the human ‘blue print’ has triggered an explosion in pharmaceutical research to utilize this knowledge in prescription of drugs to be tailored according to the genetic make up of susceptible individuals or in other words personalized medicine. Propelled by the recent unraveling of human genome; nutritional sciences are discovering the application of the so-called “omics” sciences. This has the potential of identifying and validating targets to improve personalized nutritional health and thus serves to define the added value for the next generation of foods and the crops. The first new term to emerge in this area was “Nutrigenomics.” Today, the term nutrigenomics generally refers to the study of how dietary components interact with the genome and modify subsequent gene expression1. It is envisaged that nutrigenomics will lead to evidence-based dietary interventions for prevention of diet related common diseases.

This paper describes a single tube assay for 20 fluorescent labelled Y-STR loci, which is rapid and robust state-of-art multiplex system. Reaction conditions, including annealing temperature, concentration of primers, magnesium and template DNA, DNA polymerase and reaction volume, were optimised to yield robust amplification. The assay could withstand moderate fluctuations in reaction parameters with no affect on haplotype analysis. Sensitivity and robustness of the multiplex system is revealed from the examination of different matrices and environmental conditions wherein complete haplotypes could be obtained in all the samples with no failures except those exposed to severe environmental stresses. Genotyping of the 20 Y-STR loci showed that all loci included in the multiplex are highly polymorphic in the Indian populations and its inclusion increases the discriminatory power of the marker system. It could be summarized that the developed Y-STR multiplex assay is a simple, sensitive and robust system highly suitable for concurrent analysis of 20 polymorphic Y-STR loci.

A 750 bp DNA fragment of the gag gene, coding for capsid (p26) protein of bovine immunodeficiency virus (BIV), was cloned in pQE32 vector and expressed as 6´ His tagged fusion protein in Escherichia coli. The concentration of affinity purified His tagged capsid protein was 5 mg/mL and its yield was 3.5 g/L of induced culture (E. coli). The recombinant capsid protein of BIV was found to be immunologically reactive with a reference positive serum. Using the purified capsid protein, an indirect ELISA was standardized to test sera of cattle and buffalo for carrying out sero-surveillance of BIV. Of 672 animals tested by capsid based ELISA, 162 were positive and 510 were negative, giving an overall prevalence of 24% in India. In conclusion, the recombinant capsid based indirect ELISA was found suitable to study BIV antibody status. To our knowledge, this is the first seroprevalence study of BIV infection in India.

Densonucleosis virus (DNV) is one of the pathogenic viruses of the commercially valuable silkworm, Bombyx mori. It causes flacherie disease, mostly as combined infection with other pathogens like bacteria, which accounts for the significant loss of cocoons in sericulture. Two isolates of DNV from B. mori, DNV1 and DNV2 have been previously identified on the basis of their sequences. After infection with purified isolates of DNV in some commonly used silkworm strains, viz. Nistari, C’nichi, NB1 and Guangnnong Marked, the polymerase chain reaction (PCR) was conducted using DNV1 and DNV2 primers. DNV1 primers generated a distinct profile in the B. mori strains, whereas DNV2 produced single monomorphic band in all the screened strains. Sequence of one of the prominent fragments generated by the DNV1 primer exhibited very high degree of nucleotide variability from that of Japanese DNV1 isolate, but the sequence of DNV2 showed near to complete similarity. Besides, the study demonstrates that PCR technique could be used to diagnose the DNV presence/absence in silkworm strains without sacrificing the larvae and the results could be used in breeding programmes.
