“…The levels of the variables (Table S3) for the CCD experiments were selected according to the results of the previous experiments. For these three factors, this trial was essentially a 2 3 factorial design increased by six axial points (also called star points) and two replications of the centre point (all of the factors were at level 0), resulting in a total of twenty experiments (Hwanhlem et al ., ). The distance of the star points from the centre point was α=2 (n/4) =1.682 (for three factors, n = 3).…”

A total of fifty-six strains of lactic acid bacteria isolated from Chinese sauerkraut juice from Shenyang were screened for glucansucrase production. Among them, strain DRP105 was detected to produce highest yield of glucansucrase in MRS broth, which was identified to be Leuconostoc mesenteroides. Based on Plackett-Burman Experiment, sucrose, sodium acetate and initial pH were found to be the most significant factors for glucansucrase production of L. mesenteroides DRP105. Afterwards, effects of the three main factors on glucansucrase activity were further investigated by central composite design, and the optimum composition was sucrose 35.74 g L À1 , sodium acetate 6.46 g L À1 and initial pH 5.90. Optimum results showed that glucansucrase activity was increased to 6.26 AE 0.09 U mL À1 in 24 h fermentation, 33.19% higher than before. Our study also suggested that Tween 80 and dextran have potential to improve glucansucrase stability at temperature (30°C) higher than enzyme storage temperature in crude fermented broth.Considering the culture conditions reported in previous studies, we set the main factors in this study as follows: initial pH of 4. 0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5 and 8.0; temperatures of 20, 25, 30, 35, 40 and 45°C; rotary speeds of 0, 50, 80, 100, 120, 150 and

“…Many research studies proved on identify antimicrobial compounds from mangrove sediments. Only a few studies demonstrated the nature of the antimicrobial compound produced by associated mangrove bacteria (Hwanhlem et al, 2014;Balakrishnan et al, 2014). In the present study, the compound showed to be a protein in nature.…”

“…This report agrees with this study as these genera were monitored at the last part of fermentor operation (e.g., days 24 and 28). Lactic acid producing bacteria are non-spore forming Gram-positive bacteria with rod or spherical morphology [28]. Unlike other anaerobic bacteria, they can grow in the presence of oxygen [29].…”

a b s t r a c tTo identify causes affecting the stability of biohydrogen production from the microbial community perspective, a fermentor was operated using galactose as a substrate for 30 days. The fermentor demonstrated that hydrogen production yield gradually increased with concomitant decrease of galactose concentration until day 27. Meanwhile, hydrogen producing clostridia gradually increased their proportion to 75% of bacteria analyzed until day 11, and then gradually decreased to 23% with increases in other groups of bacteria such as Bacilli. After day 27, hydrogen production abruptly failed without deterioration of galactose utilization. At that time, lactic acid accumulated to 920 mg COD/L and Ruminococcaceae increased its proportion to 30%. In conclusion, low substrate levels, beginning on day 11, provided a selective disadvantage to the hydrogen producing clostridia and proliferated other groups of bacteria, which resulted in accumulation of lactic acid and, ultimately, failure of hydrogen production.
