Public attitude towards modern biotechnology

This article reviews the literature related to the main idea of the study, rooting from the definition of biotechnology, global status of commercialized biotechnology products, and global and local public attitudes towards modern biotechnology and past models for attitude towards modern biotechnology. The first section of the review will be the in-depth-discussion regarding the definition of modern biotechnology according to several established international organizations, followed by global status of commercialized biotechnology products which will emphasize on how modern biotechnology is classified and which area are being focused more by the stakeholders, and global and local public attitudes towards modern biotechnology based on previous studies. Last but not least, the final section is credited to past studies related to attitudes and past models of public attitudes towards biotechnology, both globally and locally. A developing country like Malaysia was chosen in this article as an example of the case study related to local situation of modern biotechnology.Key words: Modern biotechnology, genetically modified (GM), public attitude, Malaysi

Biopiracy and states’ sovereignty over their biological resources

In the last several decades, indigenous communities had to contend with the misappropriation of their biological resources and associated traditional knowledge (TK) through the inappropriate exercise of intellectual property rights (IPRs). The advent of modern biotechnology has intensified this problem leaving indigenous communities increasingly vulnerable. As a counter measure, the Convention on Biological Diversity (CBD) was adopted in 1992, proclaiming the sovereignty of states over their biological resources, and requiring their consent and the equitable sharing of benefits on mutually agreed terms as conditions for access. On October 29, 2010, the Nagoya Protocol was adopted to implement these provisions. Nevertheless, the CBD has attracted critical comments from those opposed to the idea of state sovereignty over biological resources, especially when the exercise of sovereignty transcends a state’s territorial borders. Two alternative doctrines; “the common heritage of mankind”, and “the global commons”, have been canvassed. This paper set out to analyse these arguments together with the alternative doctrines, in order to determine whether state sovereignty over biological resources as proclaimed by the CBD is justified. The merits of each doctrine were examined against the background of the problems presented to indigenous communities by the trinity of biopiracy, IPRs and modern biotechnology. The paper found that the doctrine of state sovereignty over biological resources, whilst having its limitations, is not only normatively justified, but is also, comparatively more capable of helping to protect the biological resources and associated TK of indigenous communities against piracy.Key words: Indigenous communities, biological resources, traditional knowledge, biopiracy, Convention on Biological Diversity (CBD), plant breeders’ rights, patents, sovereignty

The need for biosafety regulation in developing countries: Benefits and controversies

Nowadays, the rapid development of biotechnology has become a main concern for a larger part of the world. It has become one of the most promising fields which guarantee returns to businesses and offers benefits to the society. When dealing with biotechnology, the first issue that comes to mind is the safeness of the technology from tip to toe, that is, the safeness of the products of biotechnology, how they can be used on human beings and animal, and their effects on the environment. The objective of this paper is to assess the needs and adequacy of the regulation in developing countries compared to the developed countries. In order to address these concerns, governments have adopted appropriate regulations to ensure the safety of the biotechnology products, and to protect not just human but the environment universally. This paper will discuss those regulations, especially as adopted by developing countries along with their implications. It is hoped that the paper will recover the lack of the regulations in relation to developed country.Key words: Biotechnology, biosafety, developing countries, benefits, risks and controversies

Isolation and characterization of cyclo-(tryptophanyl-prolyl) and chloramphenicol from Streptomyces sp. SUK 25 with antimethicillin-resistant Staphylococcus aureus activity

This is the first report of isolation of Streptomyces strain from the root of this plant. Strain Universiti Kebangsaan 25 (SUK 25) has a very high activity to produce secondary metabolites against methicillin-resistant Staphylococcus aureus (MRSA), which is associated with high morbidity and mortality rates due to acquired multidrug resistance genes and causes medication failure in some clinical cases worldwide. Phylogenetic analysis based on the 16S ribosomal RNA gene sequence exhibited that the most closely related strain was Streptomyces omiyaensis NBRC 13449T (99.0% similarity). Aim: This study was conducted to carry out the extraction, identification, and biological evaluation of active metabolites isolated from SUK 25 against three MRSA strains, namely, MRSA ATCC 43300, MRSA ATCC 33591, and MRSA ATCC 49476. Materials and methods: The production of secondary metabolites by this strain was optimized through Thronton’s media. Isolation, purification, and identification of the bioactive compounds were carried out using reversed-phase high-performance liquid chromatography, high-resolution mass spectrometry, Fourier transform infrared, and one-dimensional and two-dimensional nuclear magnetic resonance. Results: During screening procedure, SUK 25 exhibited good antimicrobial potential against several strains of MRSA. The best biological activity was shown from fraction number VII and its subfractions F2 and F3 with minimum inhibitory concentration values at 16 µg/mL and 8 µg/mL, respectively. These two subfractions were identified as diketopiperazine cyclo-(tryptophanyl-prolyl) and chloramphenicol. Conclusion: On the basis of obtained results, SUK 25 isolated from Z. spectabile can be regarded as a new valuable source to produce secondary metabolites against bacteria, especially MRSA.

CRISPR-based genomic tools for the manipulation of genetically intractable microorganisms

Genetic manipulation of microorganisms has been crucial in understanding their biology, yet for many microbial species, robust tools for comprehensive genetic analysis were lacking until the advent of CRISPR–Cas-based gene editing techniques. In this Progress article, we discuss advances in CRISPR-based techniques for the genetic analysis of genetically intractable microorganisms, with an emphasis on mycobacteria, fungi and parasites. We discuss how CRISPR-based analyses in these organisms have enabled the discovery of novel gene functions, the investigation of genetic interaction networks and the identification of virulence factors
