Abstract

Molecular analysis of Lactobacillus fermentum isolates is essential to understand their genetic variation in relations to their roles in sayur asin fermentation process. Combination of three molecular techniques which is restriction fragment length polymorphism (RFLP) of 16S23S rDNA intergenic spacer region (ISR), random amplified polymorphic DNA (RAPD-PCR) and an enterobacterial repetitive intergenic consensus (ERIC-PCR) analysis were performed to discriminate 19 representative isolates of L. fermentum isolated from sayur asin. The result showed that L. fermentum strain D11 is distantly related to other isolates based on RFLP using HhaI restriction enzyme and RAPDPCR analyses. In addition, both of RAPD-PCR and ERIC-PCR successfully determined the genetic variation among L. fermentum strains by exhibiting distinct 4-8 bands (800-2080 bp) and 4-10 bands (280-3050 bp), respectively. A dendogram generated from UPGMA cluster analysis of both RAPD-PCR and ERIC-PCR data showed two distinct genotypic groups exist among L. fermentum isolated from sayur asin in Indonesia.

Abstract

Krisis ekonomi yang terjadi di Indonesia terutama bersumber dari dalam negeri kita sendiri.Pemerintah orde baru, terutama sejak era konglomerasi (1987-1994), terlalu mengabaikan berkembangnya kesenjangan.Pertumbuhan ekonomi ternyata hanya sebuah fatamorgana (Mubyarto,2000). Krisis ekonomi 1997-1998 dan keadaan politik yang tidak menentu, mengakibatkan nilai mata uang rupiah dalam tempo yang amat singkat, menurun drastis. Indonesia pun langsung terpuruk. Kegiatan ekonomi tersendat karena sebagian besarnya sangat tergantung kepada bahan baku impor. Banyak perusahaan yang gulung tikar dan banyak buruh terpaksa di PHK. Jumlah penganggur dan jumlah penduduk miskin meningkat dengan tajam.

Abstract

Three hundred years ago, a Sweden expert, Carl von Linne had laid down a very basic and strong foundation in naming all the living organisms on earth.Supposedly, without the brilliant effort of Carl von Linn6, nowadays, there may have any chaos among people around the world in naming all the living creatures, because everyone would have given the name to those organisms, due to their own sense; thus a kind species may have thousands of name. If this is happen, then all the information regarding the species (including its benefit to mankind) may have no meaning at all. All people would have spoken about a species differently, without realize that they actually regarding about the same species.The center of references such as Herbarium Bogoriense and Museum Zoologicum Bogoriense may be not existed without the work and service of Carolus Linnaeus. No one nowadays arguing the great service of Carolus Linnaeus in naming of each living organisms based on binomial nomenclature.
