ABSTRACT Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant juice, for example, can be used for production of lactic acid using LAB. In a process named ‘ENLAC’, recovery of protein and chlorophyll from silage by simultaneous lactic acid fermentation and enzyme hydrolysis has been developed. Furthermore, a process for protein recovery was recently developed by applying a specific LAB starter culture to green juice from freshly harvested crops. This paper focuses on reviewing LAB for their applications within biorefining of ‘green’ crops such as clover, alfalfa, grasses and other green plant materials.

Abstract. Kusharyati DF, Pramono H, Ryandini D, Manshur TA, Dewi MA, Khatimah K, Rovik A. 2020. Bifidobacterium from infant stool: the diversity and potential screening. Biodiversitas 21: 2506-2513. Bifidobacteria spp. are a group of Lactic Acid Bacteria commonly found in the gastrointestinal tract of adults and infants. LAB are known as probiotics and have many health benefits. This research aimed to isolate Bifidobacteria from infant stool, identify, explore their diversity, and screen their potential as probiotics. Stool samples were collected from 3 healthy infants in Banyumas Regency. The potential screening included lysozyme resistance, antimicrobial activity, and exopolysaccharide production. A total of 7 Bifidobacterium species were isolated from infant stool: B. catenulatum, B. minimum, B. indicum, B. dentium, B. asteroides, B. galicum, and B. coerinum. B. indicum isolates (Bb3F and Bb1B) had the greatest inhibition activity against Escherichia coli and Candida albicans with 10.80 and 9.70 mm, respectively. Bifidobacteria isolates were resistant to lysozyme from egg whites up to 200 µg.mL-1. B. catenulatum Bb1A isolate had the highest yield of exopolysaccharide production with 74 mg.L-1. Among them, three Bifidobacterium strains (Bb1B, Bb2A, and Bb2E) were considered potentially as probiotics.

Pure Cultures

Lactic acid bacteria (LAB) are an important group in the industrially using microorganisms. The first pure cultures of bacteria was "Bacterium lactis" (probably Lactococcus lactis), obtained in 1873 by J. Lister. LAB are Gram-positive, non motile, non spore-forming, except Sporolactobacillus inulinus, catalase negative, microaerophilic or anaerobic microorganisms. LAB can be found in milk and dairy products, plants and human and animal intestinal mucosa. LAB have low Guanine and Cytosine (G+C) ratio.The industrial applications of lactic acid bacteria is considered, it is emphasized that reliable typing methods in strain levels are getting important about both study on cultures used in functional foods and determining the performance of LAB starter cultures. Denaturing Gradient Gel Electrophoresis (DGGE) is the most common technique in molecular fingerprinting culture-independent techniques. The technique is based on the separation of the same length but having different sequences of the Polymerase Chain Reaction (PCR) products.
