Prospects and technological advancement of cellulosic bioethanol ecofuel production

Abstract: Energy security, rapid depletion of fossil fuels and the huge greenhouse gas emission from the utilization of fossil fuels are the growing concerns in today's world. Bioethanol is considered as one of the attractive ecofuel due to its environmental sustainability and renewability over fossil fuels. So far cellulosic ethanol (second generation) production has gained attention at commercial scale over the other feedstocks such as first, third and fourth generation as it has no impact on food security. Third and fourth generation bioethanol technologies are in the immature stage and need further research. In this study, an outline of the systematic development of bioethanol production has been presented. The advancements in bioethanol technology and the status of installed commercial/pilot/demonstration scale plants based on lignocellulosic feedstocks all over the world have been highlighted. Finally, we have tried to underline the issues and challenges associated with the commercial scale production of cellulosic ethanol.

Inhibitory effects of probiotic potential lactic acid bacteria isolated from kimchi against Listeria monocytogenes biofilm on lettuce, stainless-steel surfaces, and MBEC™ biofilm device

Abstract: Probiotics show great promise as alternative and environmentally friendly candidates to control microbial pathogens. Here, six isolated lactic acid bacteria (LAB) were chosen based on their anti-listerial activity. Anti-listerial LAB isolates were identified by 16S rRNA gene sequencing. The anti-listerial activities of these isolates were evaluated by Listeria monocytogenes biofilm inhibition assays on stainless-steel coupons (SS), lettuce, and a minimum biofilm eradication concentration (MBEC™) biofilm device. Results revealed that following co-culture with LAB for 24 h, L. monocytogenes biofilm cells were inhibited by up to 2.17 log CFU/cm2, 1.62 log CFU/cm2, and 1.09 log CFU/peg on SS, lettuce, and MBEC™, respectively. Although these LAB bacteria suppressed L. monocytogenes biofilm formation on both surfaces, the inhibitory effect on lettuce surfaces was lower than that on SS. These results support the potential use of LAB strains to inhibit biofilm formation by pathogenic bacteria on vegetable products and in the food industry, without associated risk to consumers.
