“…Some psychrotolerant yeasts only exhibited extracellular amylase or cellulase activity at a narrow range of low temperature and pH values ( Carrasco et al, 2016 ), unlike B. subtilis ZIM3, which could adapt to a wider range of temperature and pH values. Interestingly, there were previous attempts to employ the thermostable cellulase- and amylase-producing bacteria for the biodegradation of tobacco waste extract and food wastes ( Awasthi et al, 2018 ; Ye et al, 2019 ). In this study, we attempted to improve the quality of tobacco leaves by biodegradation of starch, cellulose, and protein in flue-cured tobacco leaves via fermentation, and hopefully could produce distinctive flavor.…”

“…A study showed that expression of enzymes such as β-1,4-glucosidase and β-1,4-endoglucanase in the ethanologenic E. coli was found as better biomass hydrolysis ( Munjal et al, 2015 ). Nowadays, many studies are mainly focused on bacteria strain itself producing thermostable amylase and cellulase enzymes, and these results showed that many wild-type strains could biodegrade the food waste, tobacco waste, and wastepaper ( Poorna and Prema, 2007 ; Awasthi et al, 2018 ; Ye et al, 2019 ). However, few researches are involved in genetic approaches for improvement of microbial enzyme activity applied in tobacco fermentation.…”

In this study, a series of bacteria capable of degrading starch and cellulose were isolated from the aging flue-cured tobacco leaves. Remarkably, there was a thermophilic bacterium, Bacillus subtilis ZIM3, that can simultaneously degrade both starch and cellulose at a wide range of temperature and pH values. Genome sequencing, comparative genomics analyses, and enzymatic activity assays showed that the ZIM3 strain expressed a variety of highly active plant biomass-degrading enzymes, such as the amylase AmyE1 and cellulase CelE1. The in vitro and PhoA-fusion assays indicated that these enzymes degrading complex plant biomass into fermentable sugars were secreted into ambient environment to function. Besides, the amylase and cellulase activities were further increased by three- to five-folds by using overexpression. Furthermore, a fermentation strategy was developed and the biodegradation efficiency of the starch and cellulose in the tobacco leaves were improved by 30–48%. These results reveal that B. subtilis ZIM3 and the recombinant strain exhibited high amylase and cellulase activities for efficient biodegradation of starch and cellulose in tobacco and could potentially be applied for industrial tobacco fermentation.

Bacterial cellulose (BC) is a natural polymer secreted as a protective cell covering of certain bacterial species. In contrary to plant cellulose, BC possesses some unique features like high moisture-holding capacity, high durability, high liquid absorbing capabilities, biostability, and biodegradability, makes BC an excellent raw material in wide-ranging areas like biomedical, food, agriculture, paper, textile industries and electronics. The main objective of this review is to discuss various aspects of BC production (different sources for bacterial strain isolation, culture media and, its alternatives also major culture techniques). In addition, various applications of BC are also reviewed.

“…Biokompatibilitas sendiri merupakan suatu kemampuan material saat dipergunakan pada tempat yang spesifik pada organ tubuh dapat berinteraksi pada jaringan hidup/sel-sel namun tidak memicu atau menimbulkan suatu respon imun dan toksisitas (Ma'ruf, 2018). Selain itu selulosa bakteri secara alami mampu terurai dengan sangat baik (Ye et al, 2019) serta memiliki daya serap air yang tinggi (Novikov et al, 2021).…”

Selulosa bakteri merupakan polimer yang memiliki aplikasi yang luas dan menjanjikan dalam berbagai bidang medis. Tujuan dari penelitian tinjauan pustaka ini adalah untuk melakukan penelusuran pustaka untuk mengetahui apakah substrat dan kondisi fermentasi mempengaruhi kualitas selulosa yang dihasilkan dan penggunaannya di bidang farmasi. Metode pengumpulan data yang digunakan adalah dengan melakukan studi kepustakaan dengan menggunakan kata kunci pencarian: produksi dan aplikasi selulosa bakteri. Artikel ini diulas dalam 10 tahun terakhir yang membahas tentang produksi, karakterisasi, dan aplikasi selulosa bakteri dalam bidang farmasi. Artikel tersebut didapat dari berbagai penelitian yang telah dilakukan melalui mesin pencari seperti Google Scholar, PubMed, dan Science Direct. Berbagai penelitian menunjukkan bahwa substrat, konsentrasi starter, suhu, pH, waktu fermentasi dan proses pemurnian sangat mempengaruhi kualitas selulosa yang dihasilkan. Studi karakterisasi yang dilakukan meliputi SEM, TGA, kadar air dan sifat mekanik. Dalam aplikasi farmasi, selulosa bakteri dapat digunakan untuk membuat pembalut luka, pembawa obat, dan bahan masker wajah, serta stabilisator emulsi dan rekayasa jaringan.
