“…Phage regulatory proteins must be identified and their target sites in the genome characterized. Hopefully, the current rapid advances in DNA sequencing technology that are inspired by an interest in other genomes [67] will, when combined with recent significant increases in funding for dairy research [68], have a major impact on research into temperate phages. The determination of the complete nucleotide sequence of a tei~perate phage genome is now a realistic undertaking for a well-organized laboratory and would be a most significant advan~ in our knowledge.…”

Lysogeny is widespread in the lactic acid bacteria. The majority of lysogens can be induced by UV irradiation or treatment with mitomycin C, but indicator strains which allow lytic growth of the induced phage are often not easy to identify. A few temperate phages have been shown to transduce chromosomal and/or plasmid markers. Information about the molecular biology of the temperate phages from lactic acid bacteria is sparse and needs significant supplementation in order that these potentially valuable phages might be utilized more efficiently as tools for improving existing starter strains in dairy fermentations.

“…They consist of both coccoid (lactic streptococci) and rodshaped bacteria (lactobacilli). There has been speculation (Kondo & McKay 1985;Sandine 1987) on the feasibility of using genetic manipulation to improve these organisms in their capacity to act as starter cultures. In this respect there has been much recent.…”

Evidence for the conjugal transfer of the broad host range plasmid pIP501 into strains of Lactobacillus helveticus

The conjugative broad host range plasmid pIP501 was transferred from Streptococcus faecalis to a series of strains of lactic streptococci used commercially as dairy starter cultures. With these transconjugants as donors the plasmid was exconjugated to two strains of Lactobacillus helveticus and a commercially used strain of Strep. thermophilus. There was evidence that the plasmid could transfer between isogenic derivatives of one of the strains of Lact. helveticus. Transfer from Lact. helveticus to Strep. faecalis was also detected but at a low frequency. There was no evidence for the conjugal transfer of plasmid pIP501 into a strain of Lact. bulgaricus by exconjugation from either lactic streptococci or Lactobacillus sp.

“…For information on the biochemistry, physiology, plasmid biology,, genetics, and gene exchange systems in lactic acid bacteria, the reader is referred to the following reviews [19][20][21][22][23][24][25][26][27][28][29][30][31]. A paper on looking backward and forward at the practical appfications of genetic research on lactic acid bacteria was presented by Sandine in 1987 [32].…”

SUMMARYThe lactic acid bacteria are invoh'ed in the manufacture of fermented foods front raw agricultural materials such as milk, meat, vegetables, and cereals. These fermented foods are a significant part of the food processing indt'tstry and are often prepared using selected, strains that have the ability to produce desired product.s or changes efficiently. The application of gene.t!~c engineering technology to improve existing straals or develop novel strains for these fermentations is an active research area world-wide. As knowledge about the genetics and physiology of lactic acid bacteria accumulates, it becomes possible to genetically construct strains with characteristics shaped for specific purposes. Examples of present and future appfications of biotechnology to lactic acid bacteria to improve product quality are described. Studies of the basic biology of these bacteria are being actively conducted and must be continued,
