Cyclase inhibitor tripropylamine significantly enhanced lycopene accumulation in Blakeslea trispora
Yanlong Wang, Xiwen Chen, Xiao Hong, Shipeng Du, Chunxiao Liu, Wenfang Gong, Defu Chen

Highlights

・Tripropylamine exhibited the highest capability to enhance lycopene accumulation in Blakeslea trispora.
・Tripropylamine is not only an inhibitor on cyclase activity but also as a stimulator on the total carotenogenesis.
・Tripropylamine upregulated the transcript of genes associated with terpenoid biosynthesis pathway.

Simultaneous production of bioelectricity and treatment of membrane concentrate in multitube microbial fuel cell
Emre Oguz Koroglu, Afsin Y. Cetinkaya, Bestami Ozkaya, Ahmet Demir

Highlights

・Tubular microbial fuel cells (MFCs) with pipe-in-pipe multielectrode assemblies were developed.
・Utilization of MFC with mesh and spring significantly reduces internal resistance.
・A sustainable solution to membrane concentrate treatment over 70% chemical oxygen demand (COD) removal was obtained.
・The microbial community was observed on the membrane surfaces in a uniform morphology.

Characterization of partitioning behaviors of immunoglobulin G in polymer-salt aqueous two-phase systems
Yin Hui Chow, Yee Jiun Yap, Pau Loke Show, Joon Ching Juan, Mohd Shamsul Anuar, Eng-Poh Ng, Chien-Wei Ooi, Tau Chuan Ling

Highlights

・Phase composition and NaCl concentration affect the IgG partitioning significantly.
・Accumulation of IgG at the interface intensified as phase composition increased.
・This phenomenon was correlated with a linear relationship between ln G and Δ[PEG].
・A linear relationship between ln K and NaCl concentration was proposed.
・All the studied ATPSs were fitted well with the applied equation.

Periodic peristalsis increasing acetone–butanol–ethanol productivity during simultaneous saccharification and fermentation of steam-exploded corn straw
Jingwen Li, Lan Wang, Hongzhang Chen

Highlights

・Periodic peristalsis increased the ABE productivity by 44.8% in high solids SSF process.
・Periodic peristalsis improved the initial sugar conversion rate by 49.7%.
・The period of batch fermentation was shortened from 108 h to 84 h.
・Periodic peristalsis in acid-production phase at a low frequency was optimal.
