Introduce the topic of your paper. What microorganisms are of interest? Habitat? Applications for medicine and/or environment?

Section 1


Genome-atlas view of the L. plantarum WCFS1 chromosome, with the predicted origin of replication at the top. The outer to inner circles show (i) positive strand ORFs (red); (ii) negative strand ORFs (blue); (iii) GC-skew (green); (iv) G+C content (black); (v) prophage-related functions (green) and IS-like elements (purple); and (vi) rDNA operons (black) and tRNA encoding genes (red). Kleerebezem 2003.

Include some current research, with at least one figure showing data.

Section 2


Lactate and acetate production pathways in Lactobacillus plantarum. EMP, Embden–Meyerhof Parnas pathway; LDH, lactate dehydrogenase; POX, pyruvate oxidase; PDH, pyruvate dehydrogenase; PFL, pyruvate formate lyase; PTA, phosphotransacetylase; AK, acetate kinase. Quatravaux 2006.

Include some current research, with at least one figure showing data.

Section 3

Control juice (), juice containing cCFS from Lactobacillus plantarum 16 (), juice containing cCFS from Lact. plantarum 62 (). P < 0·001 (***). (b) Effect of 16 and 62 cCFS on the growth of R. mucilaginosa in yoghurt. Control yoghurt (), yoghurt containing cCFS from Lact. plantarum 16 (), yoghurt containing cCFS from Lact. plantarum 62 (). P < 0·001 (***). Crowley 2012.
Hematoxylin-eosin stained gastric sections (×20). A: Control group showed normal gastric histopathology; B: Helicobacter pylori infected group showed infiltration of inflammatory cells (arrows); C and D: Lactobacillus plantarum (L. plantarum) B7 106 CFUs/mL treated and L. plantarum B7 1010 CFUs/mL treated groups showed improvements in gastric inflammation. GE: Gastric epithelium; LP: Lamina propria; MM: Muscularis mucosae; SM: Submucosa; ML: Muscularis.Sunanliganon 2012.
