Definitions

  • biocontrol techniques in horticulture have not been commercially successful and one reason for this is that there is often a lack of reproduceability between trials in vitro and in the field. Also when compared to chemicals biological techniques suffer because of inoculum production, application and cost. Chemicals are also often preferred on the grounds of efficacy because chemicals generally work irrespective of environment or inoculum potential. Chemicals also are easier to apply to target plants and also a greater range of pathogens may be controlled.
  • U.S. Patent 4,878,936 describes the use of B cereus ATCC 53522 as having biocontrol activity and which produces a fungicide active against Phytophera megasperm .

  • Microbiology 52 552-555 (1986) which describes a variety of lactic acid bacteria isolated from plant surfaces and plant associated products which were found to be antagonistic to the phytopathogens Xanthomonas campestris, Envinia catotovora and Pseudomonas syringae.
  • treatment of bean plants with a Lactobacillus planetarium strain before inoculation with Pseudomonas syringae caused a significant reduction of the incidence of disease.

  • the biocontrol agent of the invention may be applied to the target before, during and after harvest.
  • the SDBS starter culture was stored at 4°C before use. To reactivate, equal parts of "Kialla” organically grown unbleached white flour and Milli-Q filtered water were mixed to form a smooth paste. The paste was then combined with the starter culture (1:1) sometimes it may be necessary to fully decant off the "clear layer" of accumulated acetic acid, lactic acid and ethanol from the top of the starter culture when this is more than V6 of the total volume. The culture was then incubated in a loosely covered glass jar at room temperature (23-30°C) for mostly 24 hours but up to five days.
  • the SDBS mixture appears to act fungistatically to inhibit or retard the development of anthracnose on naturally infected common mango fruits.
  • the fungistatic effect of the treatment can be eliminated when the mixture is removed from the fruit surface by washing.
  • the effect can be enhanced by prolonged exposure to the actively growing (wet) mixture by repeated dipping or by the addition of the spreader - sticker formulations Nufilm 17 and Codacide.
  • the SDBS starter culture originated from a sourdough starter which was developed by Mrs Edith Aylward of Roys Road, Palmwoods, Queensland, Australia.
  • the starter initially comprised a combination of intact grapes of the Cabernet variety and a commercial starter obtained from Germany called "BACK FERMENT” which was utilised in rye bread manufacture and such commercial starter was mixed with water and unbleached organic white flour (“KIALLA”) in equal volumes.
  • KIALLA unbleached organic white flour
  • Lactobacillus casei ssp caesi grows well on Lactose LB medium, while the other isolates either do not grow or only grow very slowly and poorly on this medium.
  • This medium to estimate the proportion of L. casei ssp casei in the total count.
  • yeast population growth seems to be very sensitive to both oxygen availability and organic acid and ethanol concentration. If yeast numbers are low in the starter at the beginning of the fermentation (in our experience due to prolonged growth and/or storage under anaerobic conditions), the population will not grow and very little ethanol production will occur. When reasonable numbers are present > 10 3 per ml, the population seems to be active in the first 24 hours of fermentation producing ethanol. This can be seen in the fermenting mix as it becomes very frothy. As the fermentation proceeds, acid accumulation and possibly oxygen depletion will limit yeast growth and activity. When this occurs the mixture stops frothing and dies down again.
  • LLA medium comprised Lactic Acid Bacteria Media using lactate. This medium comprised. 0.03% Tween 80, 1.5% fresh yeast extract, 0.6% tryptone and 2.0% lactose which was adjusted to pH 5.45 with agar.
  • SLA medium is the same as LLA medium except sucrose is utlised instead of lactose at the same concentration.
  • MLS medium is the same as LLA medium except maltose is used instead of lactose at the same concentration.
  • RSYM medium comprised 10% raw sugar, 0.05% (NH ⁇ 2 HPO 4 1.5% fresh yeast extract and 2% agar. Water is added to 100% and the pH adjusted with IN HCl to pH 6. The medium should be autoclaved before use.
  • SYM medium is the same as RSYM with sucrose being used instead of raw sugar.
  • MEA is a conventional malt extract medium obtained from Oxoid Australia.
  • PDA is a conventional potato dextrose medium also obtainable from Oxoid Australia.
  • RAA is a conventional rogosa agar medium obtainable from Oxoid Australia.

  • MRS medium is also obtainable from Oxoid Australia where 52 g of MRS broth is dissolved in 1000 ml of MilliQ H 2 O and 20 g of agar is added. The mixture is autoclaved at 121 °C for 15 minutes.
  • Table 6 shows pH profiles of the standard fermenation at 30°C.
  • Runs I and 2 yeast numbers were very low at the beginning of fermentation.
