"Pilot-scale extensive reforestation of carob trees Prosopis juliflora in the dessert region of Peru - Grau Region".

Approved: Oct. 1993

Ends: Oct. 1996

Financial Source: European Economical Comission

Ammount: 350,000 ecus (US $450,000)

Goals: Determine a new reforestation methodology to restore damages in dessertic areas. This new methodology consists mainly in:

a)Preparing the seeds to be directly planted

b)Protecting the seeds to be planted from an aeroplane (Pelletizing them).

Development: First stage: seed treatment to accelerate budding (it normally takes 14 days; the treated seed reaches 80% of its germination capacity 18 hours after the treatment, when it is suspended using cold water for posterior seeding).

Field test results: 38% of the treated seeds germinated. These were seeded using manual techniques (they were manually buried), and only 1-3% of the ones seeded from an aeroplane germinated. That was the reason why pelletizing was proposed, to avoid the damaging effects of radiation.

Second Stage: 1000 ha seeded using manual techniques and by aeroplane; the seeds will be pelletized, and is planned for the next "El Niño" event (1997). A program aiming to protect 25 trees/ha against ants and lizards (responsible for the death of young plants) will start.

Carvajal, G., J. Sanchez, M. Ayala, and A. Hase. 1996. Differential characteristics between marine and clinicalVibrio cholerae during the peruvian epidemic. In press.

Abstract: Important differences between isolated strains of marine species compared with strains from hospitalized patients were found, concluding that the marine environment is not the main cause of the cholera outbrake in Peru; there is risk when consuming raw shell fish from the contaminated zones.


Carvajal, G. 1990. Luminous bacteria and technology. Boletín de Lima (ed. internac.) 71:89-95.

Abstract: The isolation of two luminous bacterial species present in the peruvian marine environment and whicha have great biotechnological aplicability is described. Among the numerous applications derived from the use of these microorganisms is the posibility to obtain various enzymes (lipases, esterases, amilases, etc.) useful for the food industry, detergents, textiles and for the development of bacterial diagnosis methods.


Carvajal, G. 1988. Thioploca, a curious filamenous marine bacteria. Boletín de Lima (ed. internac.) 55:10-12.

Abstract: The isolation of this microorganism in the peruvian sea is described, frequently being in the marine outcropping zones and a possible indicator of the high primary productivity; it is present in the ocean bed, in the limit of anoxic conditions. This is a filamentous species and metabolizes mineral compounds in the ocean bed associated to the deposition of minerals like manganese and uranium. The future study of this microorganism for further technological research is of great interest.


Carvajal, G. and Thilly. 1988. Mutagenic activity of Mintostachys mollis (muña) in AHH1 lymphoblast cells. Plant Foods for Human Nutrition 30:105-114.

Abstract: The utility of muña extract as food preservative is described, as long as its use does not exceed 30 ug/ml concentrations which is the limit where it becomes genotoxic for human cells. Afterwards, the good preservation of precolumbine textiles of the Antropological Museum has been proved, using the essential volatile extract which eliminates the fungi rotting these valuable materials (reported on the VIII Peruvian Microbiology Congress, 1990).

Abstract: Three sustratum were made using a mixture of soil and compost, and sterilizing them with three different fractionated treatments in the autoclave along two consecutive days. The efficiency of the sterilization treatments was evaluated monitoring the disminution in the bacterial and fungal populations with standard plate count. Sterilization of all sustratum was achieved with a 45 minute treatment during the first day and a 30 minute treatment during the second day.

Abstract: The survivance and symbiotic characteristics of Bradyrhizobium sp. PLL113 strain (Phaseolus lunatus L.) innoculated in a mixture of soil and compost was studied. The population decreased significantly (P < 0,001) during storage at 4ºC for 60 days. The mixture mantained a population greater than 108 UFC/g only during the first month. The counting method using MPN showed that the strain mantained its infective capacity during storage. The dry weight of the aereal part of the innoculated plants was significantly greater (P < 0,05) than the plants innoculated with the stored mixture. This difference could had been due to the smaller population in the stored mixture and not because of a loss of symbiotic effectiveness of the strain.

Abstract: Yeast-extract-mannitol (YEM) broth, a widely used laboratory medium for the cultivation of rhizobia, was modified to reduce its cost and made it suitable for medium scale production of rhizobial legume inoculants. Yeast extract and mannitol, the most expensive ingredients, were reduced or substituted with more cheap substrates. With the addition of 1,1 g/L of glutamic acid or food grade sodium glutamate, yeast extract can be reduced to 0,05 g/L without affecting growth. Mannitol can be replaced with 12,5 g/L of pharmaceutical grade glycerin for Bradyrhizobium strains or with 10 g/L of food grade sugar for Rhizobium strains. The symbiotic properties of rhizobia grown on modified media were not affected.

Abstract: The diversity of thirty six rhizobium strains isolated from Phaseolus lunatus in the central coast of Peru was studied, grouping them along with their morphological and physiological characteristics.The growth velocity, acid or alkaline production, Zn+2 y Co+2 metallic ions resistance and 2% sodium chloride tolerance results show that 25% of the isolates showed characteristics from the Bradyrhizobium gender, and 75% from the Rhizobium gender. The appearance, sodium chloride tolerance and growth at different pH and temperature levels of the colonies was very diverse. Results suggest that the two taxonomic groups (Rhizobium y Bradyrhizobium) nodulate in Phaseolus lunatus in the central coast of Peru.

Abstract: 2000 g/L/d of D- fructose has been produced from an inuline solution in a reactor. The microorganism used was a Kluyveromyces marxianus mutant (strain KF 28), invertase and pectinase hiperproductor. The immobilized cells were used in reactors for the hydrolisis of sucrose and pectin. Most of the parameters optimized for the hydrolisis of inuline were able to be used for the other two cases; even though, some parameters had to be specially adapted, mainly for pectin hydrolisis.
