Aims: Our previous study demonstrated that Klebsiella IIEMP-3 associated with tempeh was genetically different from those of medical isolates. In addition to the whole genome sequence of Klebsiella IIEMP-3, the draft genome sequence of another isolate, i.e. IWJB-6 was employed for comparison. In this study, the details of the virulence genes and unique gene in both Klebsiella isolates were compared employing in silico and in vitro analysis. Methodology and results: Whole genome of Klebsiella IIEMP-3 and IWJB-6 were annotated to investigate the virulence factor. Klebsiella IIEMP-3 and IWJB-6 were obtained from tempeh producers in Bogor, West Java-Indonesia. Genome sequences were analyzed employing BLAST Ring Image Generator (BRIG) software. The results showed that all of the samples, including isolates IIEMP-3 and IWJB-6 did not harbor rmpA, i.e. DNA sequence for K. pneumoniae virulence factor. Conclusion, significance and impact of study: Klebsiella could be found in almost all tempeh samples from Indonesia and could be harmless for human due to the absence of rmpA and other virulence-associated genes. The significance of this study showed that IIEMP-3 and IWJB-6 isolates were more closely related to K. variicola. However, K. variicola At-22 harbored sdsA gene which is lacking in those two tempeh isolates. Combined with PCR analysis for specific gene/s; our study suggested that isolates from Indonesian tempeh were closely related to K. variicola, and proposed to be designated as K. variicola subsp. tempehensis.
Manfaat pengolahan ikan adalah untuk meningkatkan nilai ekonomis serta memperlambat terjadinya proses pembusukan ikan. Melalui diversifikasi pengolahan diharapkan dapat meningkatkan pendapatan masyarakat pesisir sekaligus menjadi solusi pemanfaatan ikan-ikan ekonomis rendah seperti ikan kadalan, ikan layang dan ikan lemuru yang banyak terdapat di pesisir Desa Pengambengan Kabupaten Jembrana, Bali. Tujuan dari pelaksanaan kegiatan pengabdian ini adalah untuk meningkatkan pengetahuan, keterampilan, dan perubahan perilaku masyarakat pesisir dalam mengoptimalkan pemanfaatan ikan lokal ekonomis rendah. Kegiatan ini dilaksanakan melalui tiga pendekatan yaitu pemberian materi diversifikasi olahan, melakukan kegiatan praktik olahan bersama, dan pendampingan kelompok sasaran. Kegiatan diikuti oleh dua kelompok sasaran yaitu Poklahsar Tanjung Cemara dan Poklahsar Tanjung Wangi. Dalam kegiatan ini diberikan pembekalan materi berupa diversifikasi olahan Sambal Ikan, Abon Ikan dan Otak-otak Ikan. Selama kegiatan praktik, kelompok sangat aktif berpartisipasi dan bersemangat untuk mempraktikkannya kembali di rumah. Hasil dari pendampingan yang dilakukan setelah kegiatan pelatihan menunjukkan bahwa kelompok telah melakukan olahan ikan dalam bentuk sambal ikan dan abon ikan dan telah menjadi produk olahan yang dijual sehingga memberikan tambahan penghasilan bagi kelompok.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
